Abstract
Morphological and molecular studies led to the description of Heteroconium triticicola as a new species isolated from roots of wheat in the United Kingdom. The new fungus shares with H. citharexyli, the type species of Heteroconium Petrak, features such as superficial mycelium, macronematous, mononematous, unbranched, straight conidiophores, monoblastic, integrated, terminal, cylindrical conidiogenous cells, and catenate, dry, simple, cylindrical, obclavate, often pale brown, smooth, multiseptate conidia. The genus Heteroconium is proposed as an anamorph within Hyaloscyphaceae.
