Hypocrea phyllostachydis and its Trichoderma anamorph, a new bambusicolous species from France

Abstract

Hypocrea phyllostachydis was collected from the bamboo species Phyllostachys bambusoides in southwestern France (Dept. Pyrenees Atlantiques). It can be distinguished from other morphologically similar species by the small subglobose or broadly ellipsoidal conidia and small ascospores. Conidiophores of the Trichoderma state of H. phyllostachydis do not branch in a pyramidal fashion, as is typical of most species of Trichoderma. Rather, it 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.
