Two novel species of (Parabambusicolaceae, Pleosporales) with their phoma-like asexual morphs.

The monotypic genus (Parabambusicolaceae, Pleosporales) was introduced for a microfungus isolated from a collection of dried stems of a dicotyledonous plant in Thailand. In this paper, we introduce two novel species, and , in this genus. Their asexual morphs comprise conidiomata with aseptate and hyaline conidia. has ascomata, asci and ascospores that are smaller than those of . Descriptions and illustrations of and are provided and the two species compared with the type species of the genus, . Evidence for the introduction of the new taxa is also provided from phylogenetic analysis of a combined dataset of partial LSU, SSU, ITS and sequence data. The phylogenetic analysis revealed a distinct lineage for and within the family Parabambusicolaceae.
