Abstract

Morphological studies and phylogenetic analyses of DNA sequences from the internal transcribed spacer (ITS) regions of the nuclear ribosomal gene repeat, a partial sequence of RNA polymerase II subunit (rpb2), and a partial sequence of the large exon of tef1 (LEtef1) were used to investigate the taxonomy and systematics of nine Hypocrea species with anamorphs assignable to Trichoderma sect. Hypocreanum. Hypocrea corticioides and H. sulphurea are reevaluated. Their Trichoderma anamorphs are described and the phylogenetic positions of these species are determined. Hypocrea sulphurea and H. subcitrina are distinct species based on studies of the type specimens. Hypocrea egmontensis is a facultative synonym of the older name H. subcitrina. Hypocrea with anamorphs assignable to Trichoderma sect. Hypocreanum formed a well-supported clade. Five species with anamorphs morphologically similar to sect. Hypocreanum, H. avellanea, H. parmastoi, H. megalocitrina, H. alcalifuscescens, and H. pezizoides, are not located in this clade. Protocrea farinosa belongs to Hypocrea s.s.
