A multilocus analysis was applied to representatives of the informal groups to determine their level of phylogenetic support as a first step towards taxonomic revision of Neonectria sensu lato and five genera are recognised.
Hypocrea/Trichoderma (Ascomycota, Hypocreales, Hypocreaceae): species with green ascospores.

The present study showed that phenotypic characters alone are generally not helpful in understanding phylogenetic relationships in this group of organisms, because teleomorph characters are generally highly conserved and anamorph characters tend to be morphologically divergent within monophyletic lineages or clades.
Systematics of the Trichoderma harzianum species complex and the re-identification of commercial biocontrol strains

The taxonomy of the T. harzianum species complex is revised to include at least 14 species, and two new combinations are proposed, T. lentiforme and T. inhamatum.

A monograph of Allantonectria, Nectria, and Pleonectria (Nectriaceae, Hypocreales, Ascomycota) and their pycnidial, sporodochial, and synnematous anamorphs

Results from the phylogenetic analyses demonstrate that species previously regarded as the genus Nectria having Gyrostroma, Tubercularia, and Zythiostroma anamorphs belong in two major paraphyletic clades.
Species delimitation in fungal endophyte diversity studies and its implications in ecological and biogeographic inferences

The results demonstrate that ITS alone generally underestimates the number of species predicted by other nuclear loci and question the use of ITS and arbitrary divergence thresholds for species delimitation.
Regiocrella, a new entomopathogenic genus with a pycnidial anamorph and its phylogenetic placement in the Clavicipitaceae.

Regiocrella is shown to be closely related to the scale insect pathogen Hypocrella and the plant-associated genera Balansia, Claviceps, Epichlöe, Myriogenospora and Neoclaviceps and to have multiple evolutionary origins within the Clavicipitaceae.
Hypocrea/Trichoderma: species with conidiophore elongations and green conidia
- P. Chaverri, L. Castlebury, B. Overton, G. Samuels
- BiologyMycologia
- 1 November 2003
Species of Trichoderma and Hypocrea that have green conidia and sterile or fertile elongations of their conidiophores are described or redescribed and their phylogenetic position explored and anamorph and teleomorph phenotype are not useful predictors of relationships.
EVOLUTION OF HABITAT PREFERENCE AND NUTRITION MODE IN A COSMOPOLITAN FUNGAL GENUS WITH EVIDENCE OF INTERKINGDOM HOST JUMPS AND MAJOR SHIFTS IN ECOLOGY
- P. Chaverri, G. Samuels
- BiologyEvolution; international journal of organic…
- 1 October 2013
The results support several interkingdom host jumps and also show that the preference for a particular habitat was gained or lost multiple times, and revealed that mycoparasitism is associated with accelerated speciation rates, which suggests that this trait may be linked to the high number of species in Trichoderma.
