Abstract

Phylogenetic analyses using internal transcribed spacer (ITS), large subunit rRNA (LSU), and small subunit (SSU) sequence data showed that Harzia, Chlamydomyces, and Olpitrichum are con-generic. Thus, Chlamydomyces, and Olpitrichum were reduced to synonymy of Harzia. The generic concept was amended and expanded accordingly. Eight new combinations were proposed. Melanospora and Sphaerodes are phylogenetically related to Harzia. However, several members of Melanospora and Sphaerodes are polyphyletic and belong to Hypocreales or Microascales in Sordariomycetes. The Proteophiala morph is not only a crucial morphological character, but also has a phylogenetical significance in defining Melanosporales. It is hypothesized that the taxa with synanamorphic or asexual Proteophiala all belong to Ceratostomataceae, Melanosporales.

Keywords: Aspergillus-like; Ceratostomataceae; Dimorphic; Gonatobotryum; Melanosporales; Proteophiala.
