Interpretive Summary: Fungi in the genus Hypocrea in their Trichoderma asexual states are useful for the biological control of plant diseases, yet many species of Hypocrea have yet to be discovered, described and tested for their biocontrol ability. A new species of Hypocrea having an asexual state similar to Trichoderma koningii was discovered in Puerto Rico growing on another fungus. This previously unknown species is given a scientific name, H. stilbohypoxyli, and is described and illustrated in both its sexual and asexual states. This research will be used by plant pathologists who are searching for fungi that can be used in the biological control of plant diseases.

Technical Abstract: Hypocrea phyllostachydis was collected from the bamboo species Phyllostachys bambusoides in southwestern France (Dept. Pyréneés Atlantiques). Hypocrea phyllostachydis can be recognized from other morphologically similar species by the small subglobose or broadly ellipsoidal conidia and small ascospores. Conidiophores of H. phyllostachydis do not branch in a pyramidal fashion, as is typical of most species of Trichoderma. Rather H. phyllostachydis has an irregular branching pattern, with a long central axis and relatively short lateral secondary branches. A key to species of Hypocrea with green ascospores from France is presented.
