Three species of Hypocrea with stipitate stromata and Trichoderma anamorphs.

AbstractHypocrea brevipes, H. poronioidea and H. capitata, a new species, were grown in pure culture from individual part-ascospores. Each produced a Trichoderma anamorph, but none of the anamorphs were referable to any named Trichoderma aggregate species. Stromata with fertile ascospores formed in cultures derived from single part-ascospores of H. poronioidea. In addition, a hyphomycetous, Acremonium-like synanamorph with hyaline conidia borne in slime formed in cultures of H. poronioidea. The distribution of H. poronioidea is extended from the Americas to Africa. These Hypocrea species and their anamorphs are described.
