During a survey of freshwater fungi in temperate southern Australia, two new taxa were found, Melanascoma panespora and Pleurothecium brunius. Morphological and molecular data place Melanascoma panespora in the Diaporthomycetidae representing a new genus. Melanascoma, along with Proliferophorum and Paraproliferophorum, form a new lineage and the family Melanascomaceae is introduced. Phylogenetic analyses using ITS, 28S, and 18S nrRNA gene sequences,, along with morphological examination revealed Pleurothecium brunius to be a new species of Pleurothecium, sister to P. aquaticum.
