Interpretive Summary: Fungi are a diverse group of organisms that influence human affairs in both good and bad ways. One group of fungi includes species that produce important industrial enzymes such as cellulase while other species can cause opportunistic infections of humans. Accurately defining species within this group is essential for safely using these fungi to produce enzymes. In this research species in this group are characterized using both molecular sequence data and microscopic structures. Eight new species were discovered and are described and illustrated as new to science. This research will be used by chemical engineers and plant pathologists, ecologists, and epidemiologists who deal with these fungi both as helpful and harmful organisms.

Technical Abstract: The Longibrachiatum Clade of Trichoderma is revised. Eight new species are described (T. aethiopicum, T. capillare, T. flagellatum, T. gillesii, T. gracile, T. pinnatum, T. saturnisporopsis, T. solani). The twenty-one species known to belong to the Longibrachiatum Clade are included in a synoptic key. Trichoderma parareesei and T. effusum are redescribed based on new collections or additional observations. Hypocrea teleomorphs are reported for T. gillesii and T. pinnatum. Previously described species are annotated.
