Microascus brevicaulissp. nov., the teleomorph of Scopulariopsis brevicaulis, supports placement of Scopulariopsiswith the Microascaceae

AbstractFive isolates of Scopulariopsis brevicaulishave been found to form perithecia in addition to typical conidia. The teleomorph is described as Microascus brevicaulissp. 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 Microascusproduce a Scopulariopsisstate in culture, this discovery now definitively links S. brevicaulis, the type species of Scopulariopsis, to the Microascaceae.
