| Abstract: | The Brevicompactum clade is recognized as a separate lineage in Trichoderma/Hypocrea. This includes T. brevicompactum and the new species T. arundinaceum, T. turrialbense, T. protrudens and Hypocrea rodmanii. The closest relative of the Brevicompactum clade is the Lutea clade. With the exception of H. rodmanii, all members of this clade produce the simple trichothecene-type toxins harzianum A or trichodermin. All members of the clade produce peptaibiotics, including alamethicins. Strains previously reported as T. harzianum (ATCC 90237), T. viride (NRRL 3199) or Hypocrea sp. (F000527, CBS 113214) to produce trichothecenes are reidentified as T. arundinaceum. The Brevicompactum clade is not closely related to species that have biological application. |
