Abstract
Collections of pathogenic fungi found on spiders from Thailand were selected for a detailed taxonomic study. Morphological comparison and phylogenetic analyses of the combined ITS, LSU, tef1, rpb1 and rpb2 sequence data indicated that these specimens formed new independent lineages within the Cordycipitaceae, containing two new genera occurring on spiders, i.e. Jenniferia gen. nov. and Polystromomyces gen. nov. Two new species in Jenniferia, J. griseocinerea sp. nov. and J. thomisidarum sp. nov., are described. Two strains, NHJ 03510 and BCC 2191, initially named as Akanthomyces cinereus (Hevansia cinerea), were shown to be part of Jenniferia. By including sequences of putative Hevansia species from GenBank, we also revealed Parahevansia as a new genus with the ex-type strain NHJ 666.01 of Pa. koratensis, accommodating specimens previously named as Akanthomyces koratensis (Hevansia koratensis). One species of Polystromomyces, Po. araneae sp. nov., is described. We established an asexual-sexual morph connection for Hevansia novoguineensis (Cordycipitaceae) with ex-type CBS 610.80 and proposed a new species, H. minuta sp. nov. Based on characteristics of the sexual morph, Hevansia and Polystromomyces share phe-notypic traits by producing stipitate ascoma with fertile terminal heads; however, they differ in the shape and colour of the stipes. Meanwhile, Jenniferia produces non-stipitate ascoma with aggregated superficial perithecia forming a cushion. A new morphology of ascospores in Jenniferia is described, illustrated and compared with other species in Cordycipitaceae.
