Russulaceae [SEP] Wood decay species
The corticioid species in "Boidinia", "Gloeopeniophorella", and "Pseudoxenasma" are saprotrophic, wood-degrading fungi that develop on dead wood. Their early-branching positions in the phylogeny suggests this has been the ancestral trophic mode of the Russulaceae, and that the mycorrhizal lifestyle "(see above)" evolved later. The saprotrophic nature of these species has been questioned, based on the observation that other inconspicuous, crust-forming fungi are ectomycorrhizal; a subsequent author reaffirms nevertheless that "[n]one of the corticioid species in the family shows any sign of mycorrhizal activity."
