In this study, we describe two novel saprobic fungi Sporocadus changchunensis and S. crataegicola. The novelty of these species is supported by both morphological characteristics and analyses using maximum likelihood (ML) and Bayesian inference (BI). Sporocadus crataegicola formed a distinct clade from S. changchunensis and S. rotundatus with 98% ML and 1.00 BPP statistical support, and the morphological character of S. crataegicola is remarkable in its distinguishable shape of ascospores and fewer septa. Sporocadus changchunensis differs from S. italicus, which was also found on Crataegus, by its narrower ostiolar canal, wider hamathecium, and smaller asci. The internal transcribed spacer (ITS) region, the large subunit (LSU) of ribosomal DNA, the RNA polymerase II subunit (rpb2), the translation elongation factor 1-alpha (tef1-α), and β-tubulin (tub2) genes were used for the phylogenetic analyses. An inoculation experiment was also performed to determine the possibility of latent pathogens on C. pinnatifida. The inoculation experiment showed that the species caused black spots on the mature leaves of hawthorn. We hypothesize that saprobes possess potential pathogenic ability that may lead to the occurrence of plant diseases under various circumstances. This study also extends the knowledge of the host range and geographic distribution of Sporocadus species in China.","PeriodicalId":48720,"journal":{"name":"Mycokeys","volume":"122 ","pages":"149-168"},"PeriodicalIF":3.6,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12447080/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145114638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present work concerns a survey of macrofungi from Motuo in Xizang, which is located at the northern edge of China's tropical zone. Three new species were identified using morphological features and DNA sequences (ITS, LSU and RPB2). Inocybe flavitomentosa sp. nov. belongs to section Umbraticae. It has a yellow, densely hairy cap and angular spores with faint knobs. This is the first species in its group to be found in the Chinese tropics. Inocybe motuoensis sp. nov. forms a basal branch in the I. xanthomelas group. It is the only purely tropical species in this group. It has a yellowish-brown cap, no caulocystidia and spores bearing 7-11 rounded nodules. Inocybe subchondrospora sp. nov. belongs to the I. fibrosoides group. Resembling the northern species I. chondrospora, it has smaller spores (10.1-12.9 × 6.0-7.2 µm) and grows in subalpine areas at an elevation of 2,400-2,500 m. These discoveries expand the known range of Inocybe in tropical Asia and support the idea that the I. xanthomelas group likely originated in tropical regions.","PeriodicalId":48720,"journal":{"name":"Mycokeys","volume":"122 ","pages":"99-121"},"PeriodicalIF":3.6,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12447083/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145114802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fagaceae, a plant family of significant ecological importance in the Northern Hemisphere, harbors a wide array of fungal species. During an investigation of pleosporalean fungi associated with woody litter from Fagaceae plants, dead wood samples with fungal fruiting bodies were collected in Henan and Jiangxi provinces, China. In this study, we describe two novel species, Pseudothyridariella fagacearum and Phaeoseptum biyangense, and report a new host record for Byssosphaeria siamensis.
