Molecular and morphological data reveal two new species of Scolecobasidium

Two species of Scolecobasidium were isolated from soil in Hainan and Hebei Provinces, China. The two taxa develop broadly ellipsoid conidia and ellipsoidal to oblong conidia, respectively. Their taxonomic placement in Scolecobasidium was confirmed by morphological similarity and phylogenetic analysis of the RNA polymerase II subunit b (RPB2) sequence data. The two fungi, which are morphologically distinct to previously described species, and occupy unique positions in the phylogenetic tree, are thus introduced as the new species Scolecobasidium terricola and S. ellipsoideum. They are described and illustrated and compared with similar species in the genus. (C) 2013 The Mycological Society of Japan. Published by Elsevier B. V. All rights reserved.
