Abstract:

Internal specialized conducting tissues, if present, are restricted to the gametophytic generation in liverworts while they may occur in both generations in mosses. Conducting tissues are unknown in the anthocerotes. Water–conducting cells (WCCs) with walls perforated by plasmodesma–derived pores occur in the Calobryales and Pallaviciniaceae (Metzgeriales) among liverworts and in Takakia among mosses. Imperforate WCCs (hydroids) are present in bryoid mosses. A polarized cytoplasmic organization and a distinctive axial system of microtubules is present in the highly specialized food–conducting

Abstract:

Many species of liverworts (<i>Hepaticae</i>) are morphologically plastic to such an extent that their proper recognition may cause difficulties even for a specialist. Central European species of the genus <i>Pellia</i> are notorious in this respect. Searching for less malleable diagnostic characters (than morphological and/or anatomical ones) we showed recently that the electrophoretic phenotypes (obtained by means of separation of enzyme proteins on starch gels) can be used for reliable identification of <i>Pellia</i> species with much reliability.

Abstract:

The neotropical hepatic flora, predominantly constituted by members of the Jungermanniales and Metzgeriales, includes a disproportionate number of genera which are endemic (over 38) and a number which evidently originated here but have shown slight and in a geological sense, modern dispersal by solitary species. Endemism is confined almost to the Jungermanniales; it is to a large degree of a unique sort: confined to highly apomorphic derivatives, often extremely reduced, sometimes confervoid or thalloid (aside from ‘normal’ sexual branches). These endemics are derivatives of basically cool-Gon

Abstract:

Spore wall development in Haplomitrium hookeri (Calobryales) is initiated while the sporocyte is in meiotic prophase. Extracellular exine precursor material is preferentially deposited within the sporocyte wall in a highly specific pattern that is predictive of the pilate – retiplilate ornamentation of the mature exine. Tripartite structures characteristic of hepatic exine are polymerized in exine precursors that become elevated on stalks of projecting cytoplasm. Plasma membranes of the cytoplasmic projections become extremely contorted and membrane displacement eventually isolates stalks from

This species was not adequately described and illustrated by Stephani or by subsequent workers. Moreover, Scott Pike (1987) misapplied the epithet, F. spinifolia, to specimens Amell had identified as F. leucoxantha, because they (Scott Pike 1988) overlooked a capsule with ripe spores in the type specimen.

This ultrastructural study of two closely related liverworts with contrasting modes of nutrition reveals very similar interactions with endophytic dikaryotic basidiomycetes. In both hepatics, collected from a variety of sites, the fungus is confined to specific regions of the gametophyte thallus, and hyphal contact with the substratum is via the rhizoids. The colonization cycle comprises a growth phase when the fungus forms large intracellular coils, host cytoplasm proliferates and the starch content of the plastids decreases, followed by senescence when the hyphae die back and aggregate into

Fossombronia capensis S.W.Amell var. spiralis Perold, var. nov. from Western Cape is described.

In F. capensis var. capensis the spirals are weak except for two Arnell collections in which they are quite strong. Subtle differences in spore ornamentation are then, perhaps, the most definitive character to separate the two varieties.

Abstract:

<i>Metzgeria</i>, a genus established in 1818, has been the subject of various taxonomic studies, with revisions leading to the recognition of several genera within the Metzgeriaceae family. Recent research indicates that <i>Metzgeria</i> constitutes over 98% of the family's species, with broad global distribution.During a bryophyte survey in Shennongjia National Park, <i>Metzgeria epiphylla</i> A. Evans was newly recorded in China, expanding the known distribution of this species beyond its previously reported locations in the South Atlantic and South Pacific regions. This represents the firs

Abstract:

The Koigorodsky National Park (56.7 thousand hectares) was established on December 7, 2019. It is located on the border of the Komi Republic and the Kirov region. An annotated list of liverworts collected in the Koigorodsky National Park has been presented in the article for the first time. The list includes 38 species and one subspecies of 28 genera, 21 families, seven orders (Blasiales, Jungermanniales, Marchantiales, Metzgeriales, Pelliales, Porellales, Ptilidiales), and two classes (Marchantiopsida and Jungermanniopsida). For each species, the article provides data on structures associated

Abstract:

Two new species of Fossombronia are described: F. angulifolia Perold from Lesotho and F. swaziensis Perold from Swaziland and Mpumalanga. F. angulifolia is characterised by erect or semi-erect, 2-4-lobed, angular leaves, by mostly incompletely reticulate spores and by rather short elaters F. swaziensis can be recognised by large, rounded or sometimes shallowly notched leaves, which are rather stiff and bi- to multistratose basally, by quite large perigonial bracts in the male plants and by spores which have irregular areolae containing tubercular inclusions

Abstract:

A new species of Fossombronia, F. renateae, from Mpumalanga and KwaZulu-Natal in southern Africa is described. It is distinguished by its reflexed, undulating leaves and often stipitate pseudoperianth with a highly convoluted mouth, as well as by completely or incompletely reticulate spores and usually by short, blunt elaters with two spirals which often form rings or coils. Notes are provided on two unnamed species from Mpumalanga which cannot be fully described as yet, since ripe spores are not available for study. Brief references are made to some tropical African species.

Abstract:

This article reviews published data on the likely occurrence of basidiomycetous endophytes in jungermannialean (leafy) liverworts and presents a new overview based on observations on freshly collected specimens supplemented with confirmation, by transmission electron microscopy, of dolipore septa in representative taxa. These associations are widespread in the Lophoziaceae and Arnelliaceae and sporadic in the Jungermanniaceae, Scapaniaceae, and Geocalycaceae. They are almost exclusively confined to taxa growing on well-drained, humus-rich substrata and are absent from epiphytes and species fro

Abstract:

The above three southern African species were described during the nineteenth century, but the descriptions are brief and mostly inadequate. The practice, albeit for justified financial reasons, of dividing collections (which were often mixed) and of distributing the parts to different herbaria, has led to some later authors applying the specific epithets to the wrong components. This has caused a great deal o f confusion, and much time and effort have been expended in sorting out these misapplications. This paper aims to correct and to report on some past mistakes.

Abstract:

Fossombronia zuurbergensis Perold, sp. nov. from Eastern Cape is described. It is distinguished by having leaves and pseudoperianths with markedly dentate margins; the spore ornamentation on the distal face consists of ridges which can be quite variable, although, at least some of them run parallel to each other in straight or curved, short or long ridges, others occurring at right angles to the former. New records for F. capensis var. capensis and F. crispa are reported for Eastern Cape.

Abstract:

Two new species with spinose spores are described from the Western Cape. F. elsieae Perold is quite a large plant, generally with almost entire leaves, its spores on the distal face having relatively few, rather coarse spines, which often appear broken and are occasionally linked to form abbreviated ridges. F. spinosa Perold is a smallish plant with irregularly lobed leaves, its spores on the distal face having numerous, fine spines, which sometimes coalesce to form short ridges.
