Fig. 2.

Schematic representation of the phylogenetic relationships of the currently recognized sections and clades in the genus Trichoderma. Clades representing sections as defined by Bissett (1991a) are boxed. The two clades of Pachybasium (A and B) are given by a vertical grey bar. The dotted line indicates the ambiguous phylogenetic placement of the H. lutea clade. Note that this is not a phylogenetic tree, but only a scheme based on several different phylogenetic trees published by Kullnig-Gradinger et al.(2002) and Chaverri et al.(2004). Branches are only given if they were strongly supported in all trees obtained until now
