 Notes. Surprisingly, Didymium nigrisporum is the most frequent and widely distributed species in the studied area. Initially described from Pradesh (India) and, so far, only reported from this country and Peru (Clark & Haskins, 2014). Similar to D. ilicinum by the prominent, calcareous columella and the formation of crystal scales or aggregations in the peridium, differing by the smaller and paler spores of D. nigrisporum. Lado et al. (2016) first cited this species in Peru. They commented on the variability in the density of the lime in the peridium in the Peruvian specimens, with lime-poor forms, lime in scales, and lime forming a crust. The material reported here shows mostly sporophores with lime scales but never crusts.
