This special edition of Mycosphere Notes commemorates the 70th birthday of Kevin D. Hyde, a seminal figure in fungal taxonomy whose work has profoundly influenced the study of fungal diversity and classification. In this paper, we provide entries on a new genus, 41 new species, five new geographical records, six new host records, and a new habitat record across 42 families, 22 orders, eight classes, and two phyla, continuing the invaluable work of Kevin D. Hyde in advancing our understanding of fungal biodiversity and distribution. The fungal species introduced in this paper were found as endophytes, epiphytes, pathogens, and saprobes on plant material and litter substrates across diverse ecosystems, including terrestrial, freshwater, and cave habitats in Brazil, China, India, the Philippines, Thailand, and Uzbekistan. Species boundaries were meticulously determined based on a rigorous process of morphological characteristics and molecular phylogenetic analysis, ensuring the accuracy of species delimitation. Heterohelminthosporium is introduced as the new genus in Massarinaceae, Pleosporales and the newly described 41 species are Allocryptovalsa hydei, Amorocoelophoma hydei, Annulohypoxylon hydei, Brunnipila hydei, Candolleomyces aliensis, Candolleomyces hydei, Ceramothyrium hydei, Corynespora hydei, Coryneum hydei, Crepidotus yunnanensis, Dacrymyces undulatomarginatus, Diaporthe hydei, Diorygma hydei, Distoseptispora monospora, Heterohelminthosporium hydei, Hevansia hydei, Hysterobrevium hydei, Keraliethelia hydei, Laccaria flavumbilicatus, Laccaria hydei, Lomaantha guizhouensis, Melomastia hydei, Microdochium guizhouensis, Muyocopron cavernae, Neoheleiosa hydei, Neottiosporina imperatae, Nigrospora guangdongense, Nigrosynnema hydei, Ophioceras hydei, Ophiocordyceps bannaensis, Orbilia longispora, Ostropomyces hydei, Periconia hydei, Phaeoseptum kunmingensis, Pseudosporidesmium hydei, Roussoella hydei, Stilbocrea hydei, Stilbocrea yunnanensis, Trichoderma hydei, Xylochrysis hydei, and Zasmidium hydei. Notably, one species was discovered in the air within a cave habitat. In addition, Favolaschia variistipitata and Hermatomyces indicus are reported as a new geographical record, and Comoclathris pimpinellae, Corynespora cassiicola, Dothiora sorbi, and Pseudocercospora snelliana are reported as new host records. Allodiatrype elaeidicola and Fusarium guangdongense are reported as new host and geographical records, and Leptobacillium coffeanum is reported as a new geographical and habitat record. We provide new molecular data for all collected species and updated phylogenetic trees, spanning multiple phyla, classes, orders, and families. This study highlights the expanding diversity of fungi and represents Kevin D. Hyde’s global collaborations in Mycology. We respectfully pay tribute to Kevin D. Hyde’s invaluable contributions to mycology, which have significantly advanced our understanding of fungal diversity.

This study provides taxonomic and phylogenetic insights into fungal taxa within Dothideomycetes and Sordariomycetes associated with medicinal plants in Southwestern China. These fungi are of significant interest for investigating their functional potential and for broader studies on medicinal plant-fungal interactions. A total of 90 fungal isolates were obtained from medicinal plants in Yunnan, Guizhou, and Sichuan Provinces, representing 27 genera, 19 families, and six orders. Among these, one species was identified in Pleurotremataceae (Dyfrolomycetales, Dothideomycetes), three in Eriomycetaceae (Monoblastiales, Dothideomycetes), and 30 species across 12 families of Pleosporales (Dothideomycetes). Additional taxa include three species in Amphisphaeriaceae and Sporocadaceae (Amphisphaeriales, Sordariomycetes), ten in Distoseptisporaceae (Distoseptisporales, Sordariomycetes), and two in Magnaporthaceae and Ophioceraceae (Magnaporthales, Sordariomycetes). Species delimitations and new taxa establishments were based on morphological characterization, cultural features, and multi-locus phylogenies. A novel genus, Testudiniscutum, is introduced, together with 32 new species: Acrocalymma kevinii, Amphisphaeria davidihuangtciae, A. hydeimucosa, Brunneofusispora kevinimucosa, Chromolaenicola hydei, Ch. hydeiwikstroemiae, Chromolaenomyces davidii, Distoseptispora combreticola, D. davidalangii, D. heptapleuricola, D. keviniligustrina, D. uncariicola, Gaeumannomyces hydeicoicis, Leptoparies hydei, Leucaenicola hydeinandinae, Lophiotrema hydeirubicola, Lo. kevinobpyriforme, Melomastia kevinhydei, Neoheleiosa hydeispora, N. hydeiverrucosa, N. septata, Neokalmusia kevinitetradii, Neoroussoella kevinii, Ophioceras hydeanum, Paraconiothyrium kevinhydei, Paraphaeosphaeria hydeihelleniae, Parathyridariella davidiseptata, Periconia hydeiguttulosa, Pseudochaetosphaeronema hydeiseptatum, Pseudoteichospora hydei, Seiridium kevinitibouchinicola, and Testudiniscutum isodonticola. Fourteen new host records are reported for Austropleospora ochracea, Distoseptispora aquatica, D. longispora, D. pachyconidia, D. yichunensis, Lophiostoma japonicum, Lophiotrema hydei, Lo. mucilaginosis, Lo. neohysterioides, Periconia alishanica, Pe. byssoides, Pe. pseudobyssoides, Pe. verrucosa, and Pseudothyridariella idesiae. Moreover, three new host and geographical records are provided for Chromolaenicola lampangensis, Distoseptispora tectonigena, and Parathyridaria ellipsoidea. Chromolaenicola nanensis is synonymized under Ch. Lampangensis based on morphological and molecular evidence. Detailed descriptions, illustrations, and taxonomic notes are provided for all new taxa and records. This study represents the first comprehensive account of fungi from medicinal plants in China, significantly enriching knowledge of fungal diversity and their ecological associations in medicinal plant ecosystems.

Furthermore, we report two new habitat records for Rhodoveronaea hyalina and Hermatomyces xizangensis, as well as a new geographical and habitat record for Polyplosphaeria appendiculata. All taxa are supported by morphological and multigene phylogenetic analyses. This contribution is dedicated to Kevin D. Hyde in celebration of his 70th birthday, in recognition of his outstanding contributions to the field of mycology.
