“…Zanclospora [ 1 ], typified with Z. novae-zelandiae , was established for dematiaceous hyphomycetes observed on plant litter or decaying wood and bark and characterised by setiform conidiophores, discrete phialides arranged in whorls and hyaline, unicellular, non-setulate conidia in slimy masses enveloping the conidiophores [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. However, the morphological characters of conidiophores, phialides and conidia vary among species and contribute to the phenotypic heterogeneity of the genus.…”

Zanclospora (Chaetosphaeriaceae) 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 Zanclospora as highly polyphyletic, with species distributed among three distantly related lineages in Sordariomycetes. Zanclospora 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 Chaetosphaeria. The generic concept is emended, and 17 species are accepted, 12 of which have been verified with DNA sequence data. Zanclospora 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 Zanclospora diversity. Our data confirm that Zanclospora is a rare genus.

“…However, species in these genera can be distinguished by the arrangement and colour of the conidiogenous cells. In Kramasamuha they are pale brown and solitary or in clusters along the conidiophores ( Subramanian & Vittal 1973 ). In Garnaudia , the conidiogenous cells are brown, and verticillate in terminal branches ( Borowska 1977 ), while in Endophragmiella the conidiogenous cells are hyaline and mainly solitary and terminal ( Hughes 1979 , Seifert et al .…”

The Genera of Fungi series, of which this is the sixth contribution, links type species of fungal genera to their morphology and DNA sequence data. Five genera of microfungi are treated in this study, with new species introduced in Arthrographis, Melnikomyces, and Verruconis. The genus Thysanorea is emended and two new species and nine combinations are proposed. Kramasamuha sibika, the type species of the genus, is provided with DNA sequence data for first time and shown to be a member of Helminthosphaeriaceae (Sordariomycetes). Aureoconidiella is introduced as a new genus representing a new lineage in the Dothideomycetes.

“…Although the conidia secede rhexolytically and carry away with them a basal frill, derived from the apex of the conidiogenous cell, the species show particular differences from species of Endophragmie/la listed above. The two excluded species are more suitably discussed elsewhere together with a consideration of Kramasamuha Subramanian et Vittal (1973) and Garnaudia Borowska (1977).

The generic name Endophragmia Duvernoy et Maire is considered untenable for more than 30 species that have been included in it. In many of these species conidia secede rhexolytically. and percurrent proliferations arise from the penultimate cell of the conidiophore and of the successive proliferations: most of these particular species are transferred to Endophragmiella Sutton. Two species described in Endophragmiella are excluded from this genus and two new species described.
