Two new species of dematiaceous hyphomycetes isolated from senescent leaves of Night-scented Lily, Alocasia odora (plant family: Araceae) are described based on light and scanning electron microscopy as well as LSU rDNA sequence analysis. One of these species observed directly on the leaves and in vitro is placed in genus Parastenella because of morphological characteristics. The other species characterized in vitro only is accommodated in the genus Ramichloridium. Molecular data indicate a close relationship of both species with Ramichloridium musae within the Mycosphaerellaceae (Capnodiales, Dothideomycetidae, Dothideomycetes).
