Abstract

Five isolates of Scopulariopsis brevicaulis have been found to form perithecia in addition to typical conidia. The teleomorph is described as Microascus brevicaulis sp. nov., characterized by small (70-130 μm diam), black, ostiolate ascocarps that are papillate or very short-necked, and with a peridium of textura angularis. The ascospores are reniform, 5-6 × 3.5-4.5 μm, smooth, and pale orange in mass. Although other species of Microascus produce a Scopulariopsis state in culture, this discovery now definitively links S. brevicaulis, the type species of Scopulariopsis, to the Microascaceae.
