Abstract:

Omphalia lapidescens is a macrofungus that is used in traditional Chinese medicine for its insecticidal and stagnation-relieving properties. The active ingredients of this fungus including proteins, polysaccharides and sterols have been demonstrated to exhibit antiparasitic, anti-inflammatory, and antitumor effects. Omphalia has been used in clinical cancer treatment. Many studies on Omphalia have concentrated on its cytotoxicity and anticancer effects. However, the investigation of its natural metabolites remains a significant area for further research. This review presents a comprehensive analysis of the research progress concerning the pharmacological components of Omphalia. The aim of this discussion is to provide a reference for further in-depth study of Omphalia, with the objective of exploring its potential value. Therefore, the focus of this review was on the classification of metabolites in Omphalia and their mechanisms of action.

Abstract:

AbstractMolecular studies have shown the type collection of Omphalina oreades to be conspecific with a small brown basidiolichen from the Appalachian range in Newfoundland, both with 4-spored basidia. Two sequences deposited in GenBank, originally identified as O. grisella, fell in the same clade. Sequences of the type collection of Omphalia grisella, with 2-spored basidia, formed a sister clade together with two GenBank deposits, one identified as O. grisella and the other as Omphalina velutina. Omphalina oreades is recombined here as Lichenomphalia oreades comb. nov., and the species redescribed and illustrated. Sequences of the internal transcribed spacer regions of nuclear ribosomal DNA (ITS rDNA) from the algae associated with two collections of L. oreades fell within a highly supported clade with members of an undetermined species of Coccomyxa. The most abundant algal ribosomal large subunit sequence from granules at the base of a different collection matched GenBank sequences identified as Chloroidium ellipsoideum, which is probably either a free-living algal species or a partner to a species of Trapeliopsis. The second most abundant sequence matched Coccomyxa subellipsoidea and is the most likely photobiont of L. oreades. Further studies are required to elucidate the relationship of L. velutina to these taxa.

Abstract:

Clitocybe umbrinopurpurascens, a rare species thus far known only from Morocco, is redescribed based on fresh collections made in Calabria (South Italy). Photographs of fresh material and drawings of the main micromorphological features of the species are provided. The type collection, in poor condition and not suitable for molecular analysis, was restudied macro- and micromorphologically and was found fully identical with the collections from Calabria. Based on molecular data, this species belongs to the genus Pseudoomphalina (type Omphalia kalchbrenneri) and the genus Neohygrophorus is treated as a synonym of Pseudoomphalina. A collection from Calabria is chosen as an epitype for P. umbrinopurpurascens. Our morphological and molecular revision of other Pseudoomphalina species did not provide evidence supporting the placement of Agaricus pachyphyllus in Pseudomphalina, or any other of the allied genera, therefore, for this species the new genus Pseudolaccaria is introduced. As there are no extant original herbarium specimens, a lectotype and epitype for Omphalia kalchbrenneri and a neotype for Agaricus pachyphyllus are designated.

Abstract:

La aplicación de la nanotecnología, específicamente de las nanopartículas en campos como la medicina, la remediación medioambiental y la agricultura pasa por conocer y entender las interacciones que ocurren entre estas y el sistema biológico, para lo cual es necesario abordar el estudio de la nano-biointerface. Con base en resultados obtenidos en el estudio de la capacidad antifúngica y antibacterial de las nanopartículas de óxido de cinc (ZnO-NPs), se hizo una revisión de ciertos fenómenos fisicoquímicos que podrían ocurrir en la interface entre semiconductor y membrana celular y explicarían la acción de dichas nanopartículas. Concretamente, se analizaron los efectos de la naturaleza semiconductora del ZnO y la existencia de defectos puntuales en el sólido, así como de las interacciones de tipo entrópico, sobre un sistema biológico. Con base en estos procesos fisicoquímicos, se estructuraron modelos cualitativos de mecanismos que permitirían explicar los efectos de la presencia de las ZnO-NPs en cultivos de diversos hongos (Omphalia sp., Colletotrichum sp. y Phoma sp.), tales como la inhibición de su crecimiento y la alteración de su ultraestructura, y de la bacteria Escherichia coli, en la cual causarían la inhibición del crecimiento hasta en un ⁓70 % y una concentración mínima inhibitoria (CMI50) de 30,40 µg/mL, sin incidencia de radiación UV.

Full text

Abstract:

The genus Omphalina is an ideal genus for studying the evolutionary mechanism of lichenization. Based on molecular phylogeny using ITS and nuLSU sequences by means of Bayesian and maximum likelihood analyses and morphological examination, combining the existence of green algae in basidiomata stipe and a Botrydina-type vegetative thallus, we described a bryophilous new basidiolichen species, Omphalina licheniformis, from a residential area of Jiangxi Province, China. This finding of unusual new basidiolichen species updated our understanding of the delimitation of Omphalina, indicating that both non-lichen-forming and lichen-forming fungal species are included simultaneously. The presence of algal cells in the basidiomata should receive more attention, as this would be helpful to distinguish more potential basidiolichens and explore the cryptic species diversity. This work provides new insights and evidence for understanding the significance of lichenization during the evolution of Agaricomycetes.

Abstract:

Changes in land cover directly affect biodiversity. Here, we assessed land-cover change in Cuba in the past 35 years and analyzed how this change may affect the distribution of Omphalea plants and Urania boisduvalii moths. We analyzed the vegetation cover of the Cuban archipelago for 1985 and 2020. We used Google Earth Engine to classify two satellite image compositions into seven cover types: forest and shrubs, mangrove, soil without vegetation cover, wetlands, pine forest, agriculture, and water bodies. We considered four different areas for quantifications of land-cover change: (1) Cuban archipelago, (2) protected areas, (3) areas of potential distribution of Omphalea, and (4) areas of potential distribution of the plant within the protected areas. We found that “forest and shrubs”, which is cover type in which Omphalea populations have been reported, has increased significantly in Cuba in the past 35 years, and that most of the gained forest and shrub areas were agricultural land in the past. This same pattern was observed in the areas of potential distribution of Omphalea; whereas almost all cover types were mostly stable inside the protected areas. The transformation of agricultural areas into forest and shrubs could represent an interesting opportunity for biodiversity conservation in Cuba. Other detailed studies about biodiversity composition in areas of forest and shrubs gain would greatly benefit our understanding of the value of such areas for conservation.

Abstract:

Heavy metal waste treatment often uses dangerous chemicals. Omphalina sp is a nonpathogenic fungi that can be used to reduce the harmful effects of waste treatment. The use of fungal biomass has advantages such as low operating costs, efficient, and high metal binding capacity, minimal sludge, metals can be recovered, biosorbent can be regenerated, raw materials available easily, can use inactivated microorganism, and does not require additional nutrients. In the present study optimization of the biomass utilization for waste water treatment was conducted by comparing batch, rotary, packbed flow, and biotray methods. Results showed that Omphalina sp can reduce mercury level up to 91.38% with rotary, 83.98% with biotray, 87.14% with pack bed flow, and 31.94% with batch methods respectively from initial Hg concentration of 3 ppm. Similarly, Omphalina sp can reduce copper level up to 23.58% with rotary, 22.66% with biotray, 10.53% with pack bed flow, 10.17% with batch methods respectively from initial Cu concentration of 100 ppm. Optimum absorption Hg and Cu occurs in the first one hour.

Full text

Abstract:

AbstractIn Omphalodium pisacomense and Omphalora arizonica the umbilicate thallus is limited on both sides by strongly gelatinized, prosoplectenchymatous cortices. Pseudocyphellae are formed abundantly on the top of tubercles and ridges; the tuberculate pseudocyphellae are predominantly confined to the upper surface in Omphalodium pisacomense and to the lower surface in Omphalora arizonica. Studies of the ascocarp ontogeny demonstrated the affiliation of Omphalodium and Omphalora to Parmeliaceae s. lat. In both genera, pycnidia and apothecia arise in the upper cortex, being differentiated entirely by cortical hyphae. The parmelioid development of the apothecia differs in the two genera. In Omphalodium pisacomensethe apothecium is incompletely zeorine, since the upper margin of the exciple remains covered by the thalline cortex, while in Omphalora arizonica the upper margin of the exciple protrudes and develops gradually, together with the thalline stalk, into a pedicel for the hymenium. The differences in developmental morphology support the view that Omphalodium and Omphalora should be treated as separate genera. The peculiarities of the parmelioid ontogeny and its implication in the evolution of lichens are discussed.

Full text

Abstract:

The European species of <i>Omphale</i> Haliday (Eulophidae: Entedoninae) are revised. The revision includes 37 species, of which eleven are newly described and the remaining 26 species are redescribed. The species are classified into six species groups, with six unplaced species. All species are fully diagnosed and thoroughly illustrated. Identification keys are provided for females and males. Two new morphological features to aid classification and identification are introduced: male genitalia and wing interference patterns (WIPs). The former has been used successfully in the classification of New World <i>Omphale</i> and the latter is used for the first time in a taxonomic revision. Male genitalia in <i>Omphale</i> have considerable interspecific variation, an unusual trait among chalcidoid Hymenoptera, and are demonstrated to be useful for classification of species and species-groups, and they also possess the only autapomorphy for <i>Omphale</i>. WIPs are useful to help separate some species, but cannot be used to define either the genus or species groups. Distributional data are compiled for each species and suggest a pan-european distribution for most species. Gall-midges are the known hosts for 14 species, and the absence of host overlap between species suggests that host specialization is a driving force for speciation. Several <i>Omphale</i> species are known only from females, or have a strong female biased sex ratio, suggesting thelytokous development. Apart from the 37 species included in this revision, the status for nine additional species (names) in species group <i>aetius</i> remain unsolved. For nomenclatorial stability, a <b>neotype</b> is designated for <i>Eulophus lugens</i> Nees (= <i>Omphale lugens </i>(Nees)). <i>Elachestus obscurus</i> Förster and <i>Derostenus sulciscuta</i> Thomson are transferred from <i>Holcopelte</i> to <i>Omphale</i> <b>comb.n</b>. <i>Derostenus radialis</i> Thomson and <i>Achrysocharella americana </i>Girault are synonymized with <i>Omphale theana</i> (Walker), and <i>O. teresis</i> Askew is synonymized with <i>O. phruron</i> (Walker), <b>syn. n. </b>The status of genus <i>Pholema</i> Graham is revised as it is removed from synonymy with <i>Omphale</i> and instead synonymized with <i>Neochrysocharis</i> Kurdjumov, <b>syn. n., </b>and the type species for <i>Pholema</i>, <i>P. microstoma</i> Graham, is transferred to <i>Neochrysocharis</i>, <b>comb. n.</b> <i>Eugerium orbatum</i> Szelényi, previously transferred to <i>Omphale</i>, is synonymized with <i>Asecodes congruens</i> (Nees), syn. n.

Abstract:

In 1999 and 2007 mycobiota of several locations in the Eastern Carpathians, Ukraine was studied. The Chornohora, Svydovets and Horhany mountain massifs were visited, especially locations with natural (primeval or near-natural) forests. Records of 32 rare, threatened or overlooked species of macrofungi are published. Ten of them are probably new to Ukraine (<em>Cordyceps rouxii, Gymnopilus josserandii, Hydropus atramentosus, H. marginellus, H. subalpinus, Hypholoma subviride, Hypoxylon vogesiacum, Lopadostoma pouzarii, Omphalina cyanophylla, Skeletocutis carneogrisea</em>) and 10 can be considered bioindicators of natural forests (<em>Cystostereum murrayi, Hohenbuehelia auriscalpium, Hydropus atramentosus, Hypoxylon vogesiacum, Multiclavula mucida, Omphalina cyanophylla, Phellinus nigrolimitatus, P. pouzarii, Rigidoporus crocatus, Skeletocutis stellae</em>). The records are compared with the mycobiota of the Poloniny National Park, Slovakia and with data on indicator species of fungi from abroad. The Eastern Carpathians (covering parts of Slovakia, Poland, Ukraine and Romania) seem to be the best refugee for rare (especially lignicolous) fungi of mountain beech and mixed forests in Europe.

Abstract:

To provide a clearer picture of fungal species relationships, increased efforts are being made to include both molecular and morphological data sets in phylogenetic studies. This general practice in systematics has raised many unresolved questions and controversies regarding how to best integrate the phylogenetic information revealed by morphological and molecular characters. This is because phylogenetic trees derived using different data sets are rarely identical. Such discrepancies can be due to sampling error, to the use of an inappropriate evolutionary model for a given data set, or to different phylogenetic histories between the organisms and the molecule. Methods have been developed recently to test for heterogeneity among data sets, although none of these methods have been subjected to simulation studies. In this paper we compare three tests: a protocol described by Rodrigo et al., an adapted version of Faith's T-PTP test, and Kishino and Hasegawa's likelihood test. These tests were empirically compared using seven lichenized and nonlichenized Omphalina species and the related species Arrhenia lobata (Basidiomycota, Agaricales) for which nrDNA large subunit sequences and morphological data were gathered. The results of these three tests were inconsistent, Rodrigo's test being the only one suggesting that the two data sets could be combined. One of the three most parsimonious trees obtained from the combined data set with eight species is totally congruent with the relationships among the same eight species in an analysis restricted to the same portion of the nrDNA large subunit but extended to 26 species of Omphalina and related genera. Therefore, the results from phylogenetic analyses of this large molecular data set converged on one of the three most parsimonious topologies generated by the combined data set analysis. This topology was not recovered from either data set when analysed separately. This suggests that Rodrigo's homogeneity test might be better suited than the two other tests for determining if trees obtained from different data sets are sampling statistics of the same phylogenetic history. Key words: data sets heterogeneity, homogeneity test, lichen phylogeny, Omphalina, ribosomal DNA.

Abstract:

The article is devoted to the study of eclectic facade sculpture in the historical center of Rostov-on-Don, considered in accordance with specific neo-styles. Sculpture plays an important compositional role in the design of the facades of Neo-Baroque monuments, emphasizing the rhythmic organization of facades, emphasizing the central and corner parts of buildings. Sculptural decor in the design of facades, designed within the neo-Greek and Neo-Renaissance, obeys the compositional rhythm set by architectural forms, is most often placed in architecturally limited fields, highlights the compositional axes of facades and more actively uses motifs of ancient origin. In general, the iconography of the sculptural decor includes plant motifs (laurel, flower, fruit garlands, flower baskets, acanthus, wreaths, rosettes), images of objects, including symbolic ones (shells, cartouches, caduceus, flowerpots, a cornucopia, a fountain, attributes of industry, trade, sciences and arts, armorial shields), zoomorphic images (mainly lion mascarons, griffins), mixanthropic and anthropomorphic images. Among the latest figurines are putti, mascarons of satyrs, Aphrodite, Hermes; belt herms of Hercules, Omphale, Deianira; sculptures of nymphs, Apollo, Ceres, goddesses of Glory; scenes from the history of Cupid and Psyche. The symbolism of the sculptural decor corresponds to the purpose of the building, expresses the ideas of prosperity and progress: Ceres, Apollo, the goddess of Glory — on the building of the City Duma; musical instruments and theatrical masks — on the theater building; plots symbolizing various types of activities — on the building of the Property Pledge Society; attributes of trade, industry, sciences, arts, mascarons of Hermes and his caduceus, cornucopia — on tenement houses; Hercules, Dejanira, Omphala, Aphrodite’s mascarons are on the mansions. There is a “universalization” of the mascarons of Hermes and his caduceus, which are used everywhere, regional motifs appear (bees, salting fish), the use of neo-style decor on the building, reproducing the type of kuren, is noted. Stylistically, the sculpture is focused mainly on classicism and the Renaissance, using the techniques of mannerism, baroque, rococo. The prototypes are the motifs of the sculptural decoration of famous buildings in St Petersburg, Vienna, Berlin, Brussels, chronologically close to the monuments under consideration.

Abstract:

AbstractA taxonomic revision of the lichenized species of the genus Omphalina in the Iberian Peninsula is presented, based upon fungal and lichen herbarium material, as well as on fresh collections. Relevant morphological and ecological features are discussed and a diagnostic key is provided. Four lichenized species, O. ericetorum, O. hudsoniana, O. meridionalis and O. velutina are recognized. A squamulose vegetative thallus (Coriscium-type) is present only in O. hudsoniana, while the other three species form a thallus of hyphal globules (Botrydina-type). Anatomical features of the vegetative thallus cannot be used to distinguish between these last three species. Whilst O. hudsoniana is known only from the montane belt of the Eurosiberian Region and O. meridionalis seems to restricted to the Mediterranean Region, living in more or less humid sites of the Supramediterranean belt, the other two species, O. ericetorum and O. velutina, are widespread.

Abstract:

A Gram-negative motile rod, strain SAM4T, was isolated from the highest positive dilution of a most probable number series inoculated with tidal-flat sediments from the German North Sea coast. The isolate grew at 4–35 °C and showed constant growth yields throughout almost the whole temperature range. Growth was observed between pH 6 and 9 and at salinities of 0.3–10.2 %. Strain SAM4T required Na+ for growth, contained bacteriochlorophyll a and was catalase- and oxidase-positive. It was nutritionally versatile growing on a variety of carbon compounds including carbohydrates, amino acids and organic acids like lactate or succinate. It grew anaerobically on complex media such as marine broth, indicating fermentation, and by reducing trimethylammonium oxide. The dominant phospholipids were phosphatidylethanolamine and phosphatidylglycerol, whereas only traces of phosphatidylcholine and an unidentified lipid were found. The major fatty acid was n-C18 : 1 ω7c. The DNA G+C content was 56.4 mol%. The isolate was identified as a member of the Roseobacter clade within the class Alphaproteobacteria. However, based on phylogenetic, phenotypic and physiological data, it clearly differs from its closest relative Tateyamaria omphalii. Therefore, a novel species is proposed: Tateyamaria pelophila sp. nov., with strain SAM4T (=DSM 17270T=LMG 23018T) as the type strain. Emended descriptions of the genus Tateyamaria and of Tateyamaria omphalii are also presented.

Abstract:

ABSTRACTA comparison is made of the light acclimation potential of seedlings of three canopy species of the tropical rain forest of Los Tuxtlas, Mexico: Cordia megalantha, Lonchocarpus guatemalensis, and Omphalea oleifera. These species showed similar growth rates in a range of microhabitats. Gap dynamics were simulated by transferring plants between three environments: beneath a closed canopy, a small gap, and a large gap. Plants of all three species were able to adjust their morphology and growth rates in response to changes in light availability. Growth rates increased when plants were moved to a (larger) gap, and decreased when plants were moved to a more shaded environment. Shade-grown plants were able to acclimate faster to increasing light availability than sun-grown plants to decreasing light availability. Also, plants moved from shady to sunny conditions showed higher relative growth rates than sun control plants, whereas sun-grown plants when moved to the shade showed lower relative growth rates than shade control plants. Species differed in their response to gap dynamics. Omphalea could not acclimate morphologically to shading, but reacted faster than the other species in response to the occurrence of a large gap. Acclimation potential seemed to be related to plasticity in physiological rather than in morphological traits. Suppressed seedlings of all three species performed well in the shade, and were able to acclimate rapidly to gap-conditions.
