Olpitrichum sphaerosporum: a new USA record and phylogenetic placement

Olpitrichum sphaerosporum, a dimorphic hyphomycete isolated from the foliage of Juniperus chinensis, constitutes the first report of this species in the United States. Phylogenetic analyses using large subunit rRNA (LSU) and internal transcribed spacer (ITS) sequence data support O. sphaerosporum within the Ceratostomataceae, Melanosporales.
