Abstract:
Collections of macromycetes made in seven municipalities in southern Brazil, viz. six in Rio Grande do Sul and one in Santa Catarina, are listed. They belonged to the Myxomycota (6 spp.), Ascomycota (54 spp.) and Basidiomycota (189 spp.). First records for Brazil could be Battarrea phalloides, Amanita rubescens, Boletus edulis and Mycena filopes, the last three found under exotic Pinus.

Abstract:
Wild mushrooms are important to the nutritional health and economic subsistence of rural populations in Mexico, but inaccurate identification of mushrooms has led to reported cases of poisoning. The aim of this study is to establish genotoxic profiles of mushrooms of the putative Amanita rubescens complex and to link those profiles with morphological attributes that suggest a correct identification of mushrooms, in order to prevent poisoning. Several combinations of amplification products (AMA, PHA, POP1, and POP2 genes) were identified in A. rubescens fungi sold in traditional markets; these genes are related to the presence of toxic polypeptides and its enzymatic regulators. The sequences correspond to a previously reported toxic gene family (MSDIM). All samples with the complete toxic gene profile presented reddish to dark-brown sporomes; this is the only attribute that visually distinguishes samples with toxic potential. Our results suggest that the mushrooms sold in traditional Mexican markets do not correspond to the A. rubescens complex. We conclude that morphological variability allows for identification of edible and inedible mushrooms.

Abstract:
The dichloromethane extraction was applied to extracted volatile compounds of the six developmental stages of caps and stipes of an Amanita rubescens mushroom and the relative contents were measured with the gas chromatography-mass spectrometry. The number of identified compounds ranged between 53 and 52, respectively, with a high ratio of alkane volatiles. The significant differences between the aroma compounds were determined in caps to identify their stages of development. The fully mature stage caps were characterized by 4,6-dimethyl-dodecane (7.69 ± 1.15%), 2-hexyl-1-decanol (11.8 ± 1.61%), 1,3-di-tert-butylbenzene (11.4 ± 1.25%), heptadecyl pentadecafluorooctanoate (2.16 ± 0.31%), and 2-hexyl-1-dodecanol (13.5 ± 1.33%). Niacinamide (3.90 ± 0.07%) and glycerol (3.62 ± 1.27%) was present in the caps in the early-stage of the rotting mushroom, which represented the 10th–12th day of fructification. The caps and stipes from the 12th–15th day of fructification were characterized by 2,3-butanediol (11.7 ± 0.13% and 8.00 ± 0.10%, respectively). Moreover, the caps from this developmental stage were characterized by 2-methyl- and 3-methyl butanoic acids (0.18 ± 0.03% and 0.33 ± 0.02%, respectively) which are typical for the rotting stage. In this study, we confirmed the effect of A. rubescens developmental stages on the aroma profile.

Abstract: The study presents first information on edible mushrooms of Guba district. Specimens were collected in 2017-19 in forest ecosystem. As a result of the study, 17 species (Amanita rubescens, Boletus edulis, B. reticulatus, Cerioporus squamosus, Clitocybe odora, Clitopilus prunulus, Coprinellus micaceus, Hortiboletus rubellus, Laetiporus sulphureus, Leccinellum pseudoscabrum, Legaliana badia, Lycoperdon perlatum, Macrolepiota mastoidea, M. procera, Russula risigallina, R. turci, Xerocomellus chrysenteron) of edible mushrooms belonging to 14 genera were identified. Legaliana badia is a new record for Azerbaijan mycobiota. All other mushroom species are new records for the study area. GPS coordinates and ecological groups of mushrooms were identified.

Abstract:
En el presente estudio se determinó el contenido de compuestos fenólicos y la actividad antimicrobiana yantioxidante en cuatro especies de hongos comestibles (Amanita rubescens, Astraeus hygrometricus, Laccaria laccata y Lycoperdon perlatum). Las actividades antimicrobianas se probaron en Staphylococcus aureus, Streptococcus agalactiae y Candida albicans. Los compuestos fenólicos y la actividad antioxidante se midieron mediante métodos espectrofotométricos. Todos los hongos presentan una alta actividad en comparación con S. agalactiae. El contenido de compuestos fenólicos se ubicó entre 1.54 - 20.93 mg GAE/g DW y la actividad antioxidante entre 0.0034 - 0.0854 mmol TE / g DW, siendo A. rubescens la especie con el valor más alto encontrado. Los resultados obtenidos de la actividad antimicrobiana utilizando el método de difusión en disco indicaron que los extractos exhibieron una actividad moderada. Sin embargo, la Concentración Mínima Inhibitoria (CMI) con ambos disolventes muestra que todas las especies de macromicetos registraron inhibición de los microorganismos en diferentes concentraciones. En general, los extractos etanólicos ejercieron una actividad antimicrobiana mayor a los obtenidos con metanol. La bacteria S. agalactiae fue el microorganismo más susceptible y S. aureus la más resistente. La mejor actividad antimicrobiana se encontró en los extractos etanólicos de A. hygrometricus y L. perlatum, principalmente en S. agalactiae, con un valor de CMI de 3.75 mg/mL. En conclusión, se sugiere que estas especies de macromicetos se pueden utilizar como fuente natural de componentes antimicrobianos y antioxidantes.

Abstract:
En un vivero forestal, a la planta se le brindan los cuidados e insumos necesarios para favorecer su calidad; con la finalidad de que tenga mejores oportunidades durante su desarrollo inicial. El objetivo del presente estudio fue evaluar la supervivencia y crecimiento en diámetro y altura de Pinus engelmannii en una reforestación, con base en la incorporación de inoculantes micorrícicos comerciales en la etapa de preacondicionamiento en vivero, y de fertilizante de lenta liberación al momento de plantar. Se evaluaron seis tratamientos: inoculante endomicorrícico con esporas de Glomus, inoculante ectomicorrícico con esporas de Amanita rubescens, Amanita sp., Lactarius indigo, Ramaria sp. y Boletus sp., e inoculante ectomicorrícico con esporas de Pisolithus tinctorius y Scleroderma citrinum, combinado con y sin fertilizante granulado Multicote 8® de lenta liberación (8-9 meses) (11 N-28 P2O5-11 K2O+ micronutrimentos). Las variables respuesta registradas fueron: supervivencia y causa de mortalidad, diámetro del tallo y altura. Los resultados indicaron que la supervivencia disminuyó paulatinamente, y a los 12 meses varió de 57 a 83 % entre tratamientos. En las variables diámetro y altura existieron diferencias significativas de los tres a los 12 meses. Los tratamientos con inoculante ectomicorrícico sin fertilización tuvieron mayor supervivencia, mientras que los tratamientos con inoculante y fertilizante mostraron mayor incremento en diámetro y altura. Se concluye que la inoculación controlada repercutió en la supervivencia, y la fertilización tuvo efecto sobre el crecimiento en campo de P. engelmannii.
