Hypocrea stilbohypoxyli and its trichoderma koningii-like anamorph: a new species from puerto rico on stilbohypoxylon muelleri. Sydowia. Vol. 55(2) pp.255-266. 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: The new species Hypocrea stilbohypoxyli and its Trichoderma anamorph are described. The species is known only from Puerto Rico where it grows on stromata of Stilbohypoxylon muelleri (Xylariales, Xylariaceae). Hypocrea stilbohypoxyli is readily distinguished from the morphologically most similar H. koningii/T. koningii by its substratum and slower growth rate, which is especially evident on SNA. Stromata are morphologically very similar to those of H. koningii and H. rufa. The anamorph is morphologically close to T. koningii, differing from T. koningii in having somewhat shorter and wider conidia. Hypocrea stilbohypoxyli differs from H. koningii/T. koningii in 3 bp in ITS-1 and 2 bp in ITS-2 sequences. Both are members of Trichoderma sect. Trichoderma. |
