Both species were identified as Phellinus rimosus by former mycologists, but both are morphologically distinct from authenticated specimen of P. rimosus. Fulvifomes boninensis is characterized by perennial basidiomata, a sulcate pileus surface becoming rimose, lack of a distinct crust on the pileus surface, subdimitic hyphal system in the context, and ellipsoid basidiospores. This species is endemic to the Bonin Islands, Japan, and is specific to the host Morus boninensis, a red-listed tree species. Fulvifomes imazekii is characterized by perennial basidiomata, sulcate and velutinous pileus surface, lack of a crust on the pileus surface, dimitic hyphal system in the context, and broadly ellipsoid basidiospores. This species is specific to Berchemiella berchemiaefolia, and is known only from Mt. Yokogura-yama, in Kochi Prefecture, Japan. Fulvifomes boninensis and F. imazekii are considered threatened, because of their high host specificity each with a threatened tree species as well as the limited distribution of the former and the extremely small number of \"mature individuals\" of the latter. The following new combinations were also proposed: Fulvifomes aulaxinus, F. pappianus, and F. tepperi.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"63 3","pages":"131-141"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/c3/00/MYC-63-131.PMC10032352.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9387054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over 20 y have passed since its first discovery but since then it has not been rediscovered. Here, we re-isolated M. yatsukahoi from the type locality and another location, Tambara Moor, Gunma, Japan. Sporophores of this species were detected by direct field observation in Sugadaira and by induction from soil from Tambara. We attempted to narrow down isolation sources of this species by investigating the excrements of Lithobiomorpha and Scolopendromorpha centipedes, which are frequently found in the two locations where the species is distributed. In both locations, we found M. yatsukahoi in the excrements of Lithobiomorpha but not Scolopendromorpha. Myconymphaea yatsukahoi appears to be a coprophilous fungus and the excrements of the predators living in soil may be promising isolation sources for understanding the hidden diversity of kickxellalean fungi.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"63 4","pages":"176-180"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/92/06/MYC-63-176.PMC10043566.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9387592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The degradation of cellulose in nature mainly depends on the cellulase secreted by microbes, which degrade cellulose into small molecular substances through chemical action, and the microbes that secrete cellulase mainly include some bacteria, fungi and actinomycetes, etc. The large and diverse microbial population contained in the mammalian gastrointestinal tract plays an important role in nutrient digestion. At present, many cellulose-degrading strains have been screened and obtained from animal digestive system and feces, such as Bacillus subtilis from the feces of Panda, Bacillus amyloliquefaciens from the cecum of goose. In this study, the fungal diversity was analysed in the fresh faeces of Tibetan sheep, Tibetan gazelle and Tibetan antelope in Qiangtang, Tibet. Results showed that the structure and species of gut fungi are different in three animals, which may be related to the different physiological functions among different animals, e.g., Tibetan antelope and Tibetan gazelle have stronger tolerance to rough feeding than Tibetan sheep. This study will lay a foundation for cellulose-degrading fungal development and provides technical support for improving rough feeding tolerance of Tibetan sheep.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"63 4","pages":"156-164"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/0b/62/MYC-63-156.PMC10042320.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9387596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tuber japonicum strains grew better on malt extract and modified Melin-Norkrans medium, and showed peak growth at 20 °C or 25 °C. This fungus utilized inorganic (NH4 + and NO3 -) and organic N sources (casamino acids, glutamine, peptone, urea, and yeast extract). Additionally, this fungus utilized various C sources, such as monosaccharide (arabinose, fructose, galactose, glucose, and mannose), disaccharide (maltose, sucrose, and trehalose), polysaccharide (dextrin and soluble starch), and sugar alcohol (mannitol). However, nutrient sources that promote growth and their effects on growth promotion widely varied among strains.
