Notes. This species stands out by the sporotheca leaning towards one side, the capillitium radiating from the base, and the fusiform, white lime nodes. Similar to Ph. viride (Bull.) Pers. , but the sporothecae in that species have yellow lime nodes. The groups of warts ornamenting the spores of the species were only observed in the collections Lado 24410, 24478, 26381, 26469, 26823, 25024, and 25441.
