Abstract

sp. nov. is described from two strains, one isolated from a mountain stream in Oregon, USA (NRRL Y-6106 = CBS 5560), and a second (NRRL YB-4169) from an unknown substrate from Marion, Illinois, USA. The species forms four hat-shaped ascospores in each deliquescent ascus and appears to be homothallic. Abundant true hyphae are produced with some having apparent dolipore-like septa. Analyses of nuclear gene sequences for the D1/D2 domains of large-subunit rRNA, small-subunit rRNA, translation elongation factor-1α, and subunits B1 and B2 of RNA polymerase II show the proposed novel species to be distinct from other species of the clade. Because of their placement in the clade, , , , and are reassigned to the genus as new combinations, and the description of the genus is emended to reflect the resulting changes in phenotypic characters.
