Abstract: | The new genus Amphirosellinia is erected to include five xylariaceous fungi with erumpent or immersed perithecioid stromata. Amphirosellinia fushanensis, A. nigrospora and A. tennesseensis are newly described, whereas A. evansii and A. quercina are new combinations. Synnematous, geniculosporium-like anamorphs are known for A. fushanensis, A. nigrospora, A. tennesseensis and A. evansii; the anamorph of the latter species was produced on natural substratum, whereas those of the former three species were produced in culture. Dichotomous keys are presented for the Amphirosellinia species and for some genera that might be confused with Amphirosellinia. Entoleuca ellisii also is described as new. It readily can be separated from the known species in the genus by its smaller ascospore size range and short ascospore germ slit. |
