ABSTRACT
An undescribed Neocosmospora with a Penicillifer anamorph was isolated from living twigs of Chamaecyparis thyoides and stems of Hudsonia ericoides in the New Jersey Pine Barrens and from a decayed basidioma of Fomes fomentarius from northwestern New Jersey. These isolates were found to be the same species as one previously collected on galls of Crataegus crus-galli in Brooklyn, New York. This is the first Neocosmospora teleomorph known to produce a Penicillifer anamorph. This new Neocosmospora is homothallic producing both the anamorph and teleomorph in culture. It is unique because of the combination of large ascospores arranged biseriately and green ascospore color on certain media. The Penicillifer anamorph has conidiophores with a biverticillate branching pattern not seen in other species of Penicillifer.
