| description | <i>Zanclospora</i> (<i>Chaetosphaeriaceae</i>) is a neglected, phialidic dematiaceous hyphomycete with striking phenotypic heterogeneity among its species. Little is known about its global biogeography due to its extreme scarcity and lack of records verified by molecular data. Phylogenetic analyses of six nuclear loci, supported by phenotypic data, revealed <i>Zanclospora</i> as highly polyphyletic, with species distributed among three distantly related lineages in Sordariomycetes. <i>Zanclospora</i> is a pleomorphic genus with multiple anamorphic stages, of which phaeostalagmus-like and stanjehughesia-like are newly discovered. The associated teleomorphs were previously classified in <i>Chaetosphaeria</i>. The generic concept is emended, and 17 species are accepted, 12 of which have been verified with DNA sequence data. <i>Zanclospora</i> thrives on decaying plant matter, but it also occurs in soil or as root endophytes. Its global diversity is inferred from metabarcoding data and published records based on field observations. Phylogenies of the environmental ITS1 and ITS2 sequences derived from soil, dead wood and root samples revealed seven and 15 phylotypes. The field records verified by DNA data indicate two main diversity centres in Australasia and Caribbean/Central America. In addition, environmental ITS data have shown that Southeast Asia represents a third hotspot of <i>Zanclospora</i> diversity. Our data confirm that <i>Zanclospora</i> is a rare genus. |
