Abstract
A coelomycete with characters resembling the asexual morphs in the family Botryosphaeriaceae was isolated from a fallen leaf of an orchid collected in Thailand. Morphological and phylogenetic analyses placed the strain in
Neoscytalidium
. Phylogenetic relationships among
Neoscytalidium
species were inferred by analyzing internal transcribed spacers and large subunit of rRNA sequence data and indicate that our strain is a new species, which is introduced and illustrated herein as
Neoscytalidium orchidacearum
sp. nov.
