Teleomorphs are reported for Trichoderma minutisporum (Hypocrea minutispora sp. nov.) and T. polysporum (H. pachybasioides). Hypocrea pilulifera/T. piluliferum is redescribed. Trichoderma croceum is synonymized with T. polysporum. The new species H. parapilulifera, H. stellata, and H. lacuwombatensis are described. All of these species fall within the morphological concept of Trichoderma sect. Pachybasium and within the phylogenetic group 'pachybasium B5' of Kullnig-Gradinger et al (2002). Parsimony analysis of nucleotide sequences from three unlinked loci ? ITS1 and 2, endochitinase (ech42) and translation elongation factor 1-alpha (tef1) - detects two distinct phylogenetic lineages within the group "pachybasium B5,' one comprising H. pachybasioides/T. polysporum, H. pilulifera/T. piluliferum, H. parapilulifera and H. stellata. This group is characterized by having conidia that are white in mass and is the only lineage within Hypocrea characterized by such conidia. The second group includes the green conidial T. minutisporum and H. lacuwombatensis. The partition homogeneity test reveals significant recombination within former, ?white-conidia? species, but not within the ?minutisporum? lineage.} }
