    Abstract:
    Several molecular studies have demonstrated that species traditionally assigned to the form genus Acremonium are polyphyletic, while Acremonium sensu stricto is a central element of the family Bionectriaceae (Hypocreales). Based on phenotypic characters and molecular phylogenetic analyses, two new Acremonium species, A. moniliforme and A. dimorphosporum, are described. The former is related to Emericellopsis and is characterised by cylindrical conidia, acicular phialides and abundantly formed moniliform hyphae. Acremonium dimorphosporum resembles A. borodinense. It produces dimorphic conidia that are either cylindrical and smooth-walled or ellipsoidal and rough-walled. The new genus Brunneomyces is proposed based on three species, including B. brunnescens (formerly A. brunnescens), B. europaeus and B. hominis. They are characterised by brown hyphae, sympodial conidiophores and chains of ovoidal to ellipsoidal conidia. Chordomyces albus sp. nov. is characterized by its light-coloured colonies, simple or branched conidiophores, phialides with percurrent proliferations and cylindrical collarettes, and ellipsoidal to cylindrical conidia. The combined analysis of the LSU, ITS, RPB2 and TEF1-¿ loci supports the inclusion of B. brunnescens, B. europaeus, B. hominis and C. albus in Plectosphaerellaceae.
