• Comments

  Inocybe albodisca can be distinguished by a two-toned cap (disc white to cream, shading to a grayish brown to vinaceous brown margin), a pallid stipe with abruptly bulbous base, spermatic odor, nodulose spores, and thick-walled cystidia. The white to cream velipellis (universal veil tissue) that persists on the cap is reminiscent of Inocybe fraudans, Inocybe brunnescens, and Inocybe bakeri. I. fraudans differs in having tissues that stain red, a strong spicy odor, and smooth spores; I. brunnescens has a hazel-brown cap, non-bulbous stipe, smooth spores, and lacks a spermatic odor; and I. bakeri has a tan to ochraceous cap and longer smooth spores.
