The true sexual state of V. prolifera is hereby described and a new combined name C. prolifera is proposed. During our studies on marine fungi along the coasts of Japan, an unknown fungus forming clavate conidia was discovered from beaches of Rishiri Island in the northern cool region of Japan and is described here as a new anamorphic species, C. clavata. Regarding the life cycle of Corollospora, 20 species have a teleomorph type life cycle, while in the other eight species, each four are teleomorph-anamorph type and anamorph type, respectively. Phylogenetic analyses revealed three species having Varicosporina anamorphs, C. anglusa, C. prolifera, and C. ramulosa are closely related, and the former two species have the teleomorph-anamorph type life cycles, and the latter one has the anamorph type. Phylogenetic and morphological data suggest that C. anglusa possibly evolved from the teleomorph type ancestor and that C. ramulosa differentiated from the teleomorph-anamorph type ancestor relating to C. prolifera.

It has been demonstrated that dispersedly retained broad-leaved ectomycorrhizal (EcM) trees can mitigate the effect of logging on the diversity of EcM fungi in the surrounding Abies sachalinensis seedlings. However, it remains unclear how retained trees of different mycorrhizal types affect the diversity of EcM fungi in Abies seedlings. We investigated the neighborhood effect of different mycorrhizal types of retained trees on the diversity of EcM fungi symbiotic with surrounding Abies seedlings. At dispersed retention sites, the roots of Abies seedlings were collected near mature EcM trees (ET) or arbuscular mycorrhizal (AM) trees (AT), or in open areas where no retained trees existed within ten meters (NT). EcM fungi were identified based on ITS barcoding of the EcM roots. The diversity measures of EcM fungi under AT and NT were comparable and lower, respectively than those under ET. The community composition of the EcM fungi was similar between AT and NT, and both were significantly different from that of ET. These results indicate that AM trees do not have significant impact on EcM fungul community in the surrounding EcM seedlings.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"66 3","pages":"195-200"},"PeriodicalIF":1.4,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13062905/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147674986","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}

Various Cercospora species have recently been reported on sugar beet associated with CLS globally. The diversity of Cercospora species on CLS that occurred in Hokkaido, Japan, was examined based on the phylogenetic analyses in this study. These isolates of Cercospora species were divided into three groups based on multi-loci molecular phylogenetic analyses with a combined matrix of DNA sequences composed of rDNA ITS, actin, calmodulin, histone, and translation elongation factor. In addition, the ATP binding cassette transporter (ATR) gene sequences were newly introduced for multi-loci phylogenetic analyses as an alternative locus. Japanese Cercospora isolates from B. vulgaris formed well-supported clades by bootstrap values, which were recognized as C. beticola, C. cf. resedae, and an unknown lineage of Cercospora species. From these results, Cercospora hokkaidensis, isolated from sugar beet in three locations across Hokkaido, was described in this study. Moreover, ATR was proposed as a new candidate species barcoding region to recognize Cercospora species.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"66 3","pages":"180-188"},"PeriodicalIF":1.4,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13062908/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147675022","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}

In this study, a Neostagonosporella-like fungus was collected from living leaves of Sasa borealis and unidentified bamboos in Japan and described as a new species (Neostagonosporella sasae) based on morphological examinations and phylogenetic analyses. This species is characterized by multiloculate ascostromata, trabeculate pseudoparaphyses, cylindrical to fusiform hyaline 5-6-septate ascospores, phialidic conidiogenesis, and two types of conidia: 3-6-septate cylindrical macroconidia and aseptate or rarely 1-septate ellipsoidal microconidia. These characteristics resemble those of N. bambusicola and N. sichuanensis. However, N. sasae differs from N. bambusicola in its substrates (vs. dead leaves of bamboo), trabeculate pseudoparaphyses, and shorter ascospores, and from N. sichuanensis in its substrates (vs. living to nearly dead stems and branches of Phyllostachys heteroclada), shorter ascospores, and larger microconidia. Phylogenetic analyses showed that N. sasae formed a robust monophyletic clade within the Neostagonosporella lineage but were separated from other known species of this genus. Furthermore, we revised the genus definition to incorporate additional ecological and morphological characteristics: bamboo leaves as substrates (previously limited to stems and branches), and cellular pseudoparaphyses (previously limited to trabeculate forms).","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"66 3","pages":"171-179"},"PeriodicalIF":1.4,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13062909/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147675041","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}

This species was found in the proventriculus (foregut) of several genera of Gryllidae and on their feces. It is distinguished from U. rhaphidophoridarum in that it has a different host, and the number and morphology of the claws of sporangiola also differ. After the host ingested sporangiola, we observed that the upper half of the sporangiola disappeared in the gut and that the claws of the sporangiola, which function as attachment structures in the proventriculus, underwent morphological changes. The claws transformed to bottle opener-like structures arranged in chains vertically with hollowed-out centers. Fine hairs on the inner surface of the proventriculus became entangled with these structures and were stuck in the gaps between the denticles of the claws, leading to attachment to the host gut.
