Abstract

In sampling fungi from the built environment, two isolates that could not confidently be placed in described species were encountered. Phenotypic analysis suggested that they belonged in sect. . In order to verify the sectional placement and to assure that they were undescribed rather than phenotypically aberrant isolates, DNA was isolated and sequenced at the beta-tubulin, calmodulin, internal transcribed spacer and RNA polymerase II loci and sequences compared with those from other species in the genus . At each locus, each new isolate was distant from existing species. Phylogenetic trees calculated from these data and GenBank data for species of the section excluded the placement of these isolates in existing species, with statistical support. Because they were excluded from existing taxa, the distinct species (type strain NRRL 35910) and (type strain NRRL 66196) in sect. are proposed to accommodate these strains.
