Figure 2.

A phylogeny of Psathyrellaceae (maximum likelihood) shows that several lineages were recruited as mycorrhizal symbionts of the mycoheterotrophic orchids Eulophia zollingeri and Epipogium roseum. Mycorrhizal taxa fall within a clade consisting of Psathyrella candolleana representatives, while others fall within the Coprinellus clade (sequences from references 12 and 14; the support values on branches correspond to maximum likelihood bootstrap probabilities, and only values above 70% are shown).
