This variation in Acadesine supplier ascospore size had led Doi (1972) to erect H. sulphurea f. macrospora. H. megalosulphurea Yoshim. Doi (Doi 1972) differs from H. sulphurea by pulvinate stromata, while H. subsulphurea Syd. has monomorphic ascospores (Overton et al. 2006b). Similar are also H. austriaca and H. victoriensis. Hypocrea austriaca differs from H. sulphurea by lighter stromata, slightly

smaller ascospores and the occurrence on Eichleriella deglubens, while no fungal host has so far been detected for the Australian H. victoriensis. The Brevicompactum , Lutea and Psychrophila Clades Introduction Species of three clades adjacent in the generic phylogenetic tree of the genus Hypocrea/Trichoderma (Fig. 1) are here subsumed, primarily in order to reach comparable quantitative scopes in each descriptive chapter. The Brevicompactum clade is the result Caspase Inhibitor VI molecular weight of an integrated approach of molecular biology (DNA sequence data), morphology, phytopathology (search for plant-protective agents useful for biocontrol of the vine diseases Eutypa dieback and Esca) learn more and profiling of secondary metabolites such as peptaibiotics and trichothecenes. First recognised by Degenkolb et al. (2006) the clade was established by Degenkolb et al. (2008a) with the

new formally described species Trichoderma arundinaceum, T. turrialbense, T. protrudens and Hypocrea rodmanii, in addition to T. brevicompactum that had been described by Kraus et al. (2004). Chemotaxonomic potential, prediction of biocontrol suitability, health concerns of secondary metabolites including trichothecenes and hydrophobins analysed by mass spectrometry of this group of species was discussed by Degenkolb et al. (2008b). Three holomorphic Hypocrea/Trichoderma species including two new ones are described in this clade below. The Lutea clade Phenylethanolamine N-methyltransferase currently comprises only the two species H. lutea and H. melanomagna (Chaverri and Samuels 2003). A third species is added below. The clade is exceptional due to the distinctly gliocladium-like anamorphs characterised by more or less mononematous penicillate conidiophores and green conidia that

are eventually embedded in a mucous exudate. Like the Semiorbis clade, this clade contains both species with hyaline and green ascospores. The typification of H. lutea is clarified here and the anamorph of H. lutea, Gliocladium deliquescens, is combined in Trichoderma. Hypocrea megalocitrina and H. psychrophila were recognised as the Megalocitrina clade (Chaverri and Samuels 2003). This was adopted by Jaklitsch et al. (2006a) when describing H. crystalligena. The clade including H. megalocitrina is now called the Psychrophila clade; it is well supported and now comprises four European species including two new ones. These species are characterised by pulvinate stromata and white-conidial anamorphs with more or less gliocladium-like conidiophores. Species descriptions Clades and the species within the clades are arranged in alphabetical order.
