ABSTRACT: During a continuing study of coprophilous fungi in Venezuela, a sordariaceous pyrenomycete with unusual ascospores was isolated from calf dung. The ascospores were composed of two, dark brown, smooth, ellipsoidal end cells that were connected by a long, hyaline, hyphal intercalary cell. These features place the fungus in Zygopleurage, a genus characterized by nonstromatic, obpyriform, ostiolate perithecia, with indistinct paraphyses and clavate, unitunicate, long-stipitate asci. The species was identified as Zygopleurage zygospora, which represents a new record for Venezuela.
