It is characterized by effuse, black, and somewhat glistening colonies on the surface of natural substratum, which are mainly composed of solitary, dry, dark, cymbiform, or ellipsoidal to obovoid, 3–4-euseptate conidia. The conidia secede rhexolytically from semi-macronematous conidiophores with percurrent regeneration. The conidia resemble those of <i>Bactrodesmium</i> species, but they are not produced from sporodochial conidiomata. Phylogenetically, this new genus is placed in the <i>Savoryellomycetidae</i> incertae sedis, closely related to <i>Flammispora</i>, but is distant from the <i>Fucosporellales</i> which contains the <i>Bactrodesmium</i> species. This new genus is proposed based on three collections from different localities in Taiwan, with descriptions of two novel species, <i>G. bactrodesmioides</i> and <i>G. tarooides</i>, which differ in conidial morphology. The two species are supported by sufficient differences in their LSU, SSU, and the ITS sequences.

It had then been identified as <i>Lachnum papyraceum</i> (<i>Lachnaceae</i>, <i>Helotiales</i>) based on morphological traits, and extracts from its mycelial cultures were found to possess extraordinary nematicidal and antibiotic activities. Over 60 different secondary metabolites were finally identified from this fungus after extensive variation of culture media and scale-up of production up to 100-L scale. Among the main active principles were mycorrhizin A and chloromycorrhizin A, which had first been reported in 1977 from an unnamed “mycorrhizal” fungus of the hemiparasitic plant, <i>Monotropa hypopitys</i> (pinesap), that was isolated in Sweden. We noted that both the <i>Lachnum</i> strain and the original mycorrhizin producer were still available in the public domain and decided to study them for comparison using a multilocus phylogeny and also generated secondary metabolite profiles of both strains using analytical high performance liquid chromatography coupled to diode array and mass spectrometric detection (HPLC–DAD/MS). Surprisingly, the sequence data as well as the secondary metabolite profiles of both strains were highly similar, and it was also confirmed by phylogenetic methods that the strains are indeed nested within the genus <i>Lachnum</i> by comparison of their ITS, LSU, and <i>RPB2</i> sequences. The specimen called <i>L. papyraceum</i> in the old publications was tentatively re-identified by Hans-Otto Baral as <i>L</i>. cf. <i>subvirgineum</i>, but substantial further work on the taxonomy of the genus remains to be done, anyway. We conclude that some <i>Lachnum</i> species have a highly complex but all the more interesting life cycle, and the mycorrhizal symbiont partner may invade the host plant, where it may persist as an endophyte and finally turn saprotrophic on the wood of the senescent pine tree. The taxonomy of these fungi should also be further resolved in the future, using a polythetic concept that includes chemotaxonomic data and a multi-locus genealogy.</p>","PeriodicalId":19111,"journal":{"name":"Mycological Progress","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141718835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
