Proposal of a new family Pseudodiploösporeaceae fam. nov. (Hypocreales) based on phylogeny of Diploöspora longispora and Paecilomyces penicillatus

| Summary: | ABSTRACTDuring a field survey of cultivated Morchella mushroom diseases, Diploöspora longispora and Paecilomyces penicillatus, causal agents of pileus rot or white mould disease were detected, which resulted in up to 80% of yield losses. Multi-locus phylogenic analysis revealed that the fungi were affiliated in a distinct clade in Hypocreales. We further constructed a phylogenetic tree with broader sampling in Hypocreales and estimated the divergence times. The D. longispora and P. penicillatus clades were estimated to have diverged from Hypocreaceae around 129 MYA and Pseudodiploösporeaceae fam. nov is herein proposed to accommodate species in this clade. Two new genera, i.e. Pseudodiploöspora and Zelopaecilomyceswere, were introduced based on morphological characteristics and phylogenic relationships of Diploöspora longispora and Paecilomyces penicillatus, respectively. Five new combinations – Pseudodiploöspora cubensis, P. longispora, P. fungicola, P. zinniae, and Zelopaecilomyces penicillatus – were proposed. |
