Notes. A recently described species by Lado et al. (2022) from Peru possesses an iridescent peridium ( Fig. 3D View FIGURE 3 ), a columella with irregular projections arranged in a reticulate fashion and spores in easily dissociable clusters, (3)5– 8(10) spores per cluster ( Fig. 3E View FIGURE 3 ). This species is the first one with this type of columella in the genus Diachea ( Martin & Alexopoulos 1969, Farr 1976, Poulain et al. 2011). Diachea mitchellii has been exclusively reported from Polylepis forests, being exceedingly abundant there.
