Mycobiology 2020 Oct 22;48(6):476-483. Epub 2020 Oct 22.

School of Biological Sciences and Institute of Microbiology, Seoul National University, Seoul, Republic of Korea.

The genus (Strophariaceae, Basidiomycota) is made up of wood-rotting saprotrophic mushrooms characterized by a yellow or brown pileus with scales and/or slimy, and by a brownish smooth spore with a germ pore. However, these features are not enough to distinguish its species, or separate the genus from other brown-spored wood-rotting genera such as and . Although internal transcribed spacer (ITS) sequence-based identification has improved identification accuracy for species of , most species in Korea are reported based on morphological features.

Screening of ecologically diverse fungi for their potential to pretreat lignocellulosic bioenergy feedstock.

Appl Microbiol Biotechnol 2014 Apr 7;98(7):3355-70. Epub 2014 Feb 7.

Department of Bioenergy, Helmholtz Centre for Environmental Research-UFZ, Permoserstrasse 15, 04318, Leipzig, Germany.

A widespread and hitherto by far underexploited potential among ecologically diverse fungi to pretreat wheat straw and digestate from maize silage in the future perspective of using such lignocellulosic feedstock for fermentative bioenergy production was inferred from a screening of nine freshwater ascomycetes, 76 isolates from constructed wetlands, nine peatland isolates and ten basidiomycetes. Wheat straw pretreatment was most efficient with three ascomycetes belonging to the genera Acephala (peatland isolate) and Stachybotrys (constructed wetland isolates) and two white-rot fungi (Hypholoma fasciculare and Stropharia rugosoannulata) as it increased the amounts of water-extractable total sugars by more than 50 % and sometimes up to 150 % above the untreated control. The ascomycetes delignified wheat straw at rates (lignin losses between about 31 and 40 % of the initial content) coming close to those observed with white-rot fungi (about 40 to 57 % lignin removal).

Clues for regulatory processes in fungal uptake and transfer of minerals to the basidiospore.

Biol Trace Elem Res 2013 Jul 12;154(1):140-9. Epub 2013 Jun 12.

Institute of Geosciences, Friedrich-Schiller-University, Burgweg 11, 07749 Jena, Germany.

Several fungal species are notorious for the preferential acquisition of toxicants such as AsCdHgPbU in their wild-grown basidiomes, but it is not known how, or whether at all, mineral uptake is regulated. In this study, basidiomes of Kuehneromyces mutabilis, Pleurotus ostreatus, and Hypholoma fasciculare were grown on Fagus sylvatica logs embedded in sand, uranium-overburden soil, and garden soil (SIO) at a lab scale to raise the accessible mineral resources 30 to >1,000 times over those available in the timber alone. Non-embedded logs and a field culture established on SIO served as controls. Read More

Outcomes of fungal interactions are determined by soil invertebrate grazers.

Ecol Lett 2011 Nov 19;14(11):1134-42. Epub 2011 Sep 19.

Cardiff School of Biosciences, Cardiff University, Museum Avenue, Cardiff, CF10 3AX, UK.

Saprotrophic fungal community composition, determined by the outcome of competitive mycelial interactions, is one of the many key factors affecting soil nutrient mineralisation and decomposition rates. Fungal communities are not generally predicted to be regulated by top-down factors, such as predation, but rather by bottom-up factors, including resource availability. We show that invertebrate grazers can exert selective pressures on fungal decomposer communities in soil, reversing the outcomes of competitive interactions. Read More

Simulated nitrogen deposition affects wood decomposition by cord-forming fungi.

Oecologia 2011 Dec 7;167(4):1177-84. Epub 2011 Jul 7.

Earthwatch Institute, Oxford, UK.

Anthropogenic nitrogen (N) deposition affects many natural processes, including forest litter decomposition. Saprotrophic fungi are the only organisms capable of completely decomposing lignocellulosic (woody) litter in temperate ecosystems, and therefore the responses of fungi to N deposition are critical in understanding the effects of global change on the forest carbon cycle. Plant litter decomposition under elevated N has been intensively studied, with varying results. Read More

Saprotrophic basidiomycete mycelia and their interspecific interactions affect the spatial distribution of extracellular enzymes in soil.

FEMS Microbiol Ecol 2011 Oct 26;78(1):80-90. Epub 2011 May 26.

Laboratory of Environmental Microbiology, Institute of Microbiology of the ASCR, Prague, Czech Republic.

Saprotrophic cord-forming basidiomycetes are important decomposers of lignocellulosic substrates in soil. The production of extracellular hydrolytic enzymes was studied during the growth of two saprotrophic basidiomycetes, Hypholoma fasciculare and Phanerochaete velutina, across the surface of nonsterile soil microcosms, along with the effects of these basidiomycetes on fungi and bacteria within the soil. Higher activities of α-glucosidase, β-glucosidase, cellobiohydrolase, β-xylosidase, phosphomonoesterase and phosphodiesterase, but not of arylsulphatase, were recorded beneath the mycelia. Read More
