Abstract

Based on analyses of concatenated internal transcribed spacer regions of the nrDNA operon (ITS), large subunit rDNA (LSU), γ-actin and β-tubulin gene sequences the taxonomy of coniothyrium-like fungi belonging in the family Montagnulaceae, order Pleosporales, was re-assessed. Two new genera are proposed, Alloconiothyrium, to accommodate A. aptrootii sp. nov., and Dendrothyrium for D. longisporum sp. nov. and D. variisporum sp. nov. One new species is described in Paraconiothyrium, viz. Parac. archidendri sp. nov., while two species so far classified in Paraconiothyrium are transferred to Paraphaeosphaeria, viz. Paraph. minitans comb. nov. and Paraph. sporulosa comb. nov. In Paraphaeosphaeria five new species are described based on asexual morphs, viz. Paraph. arecacearum sp. nov., Paraph. neglecta sp. nov., Paraph. sardoa sp. nov., Paraph. verruculosa sp. nov., and Paraph. viridescens sp. nov. Macro- and micromorphological characteristics are fully described.
