Notes. This species is very variable morphologically, and some authors distinguish among three varieties according to the spore diameter ( Poulain et al. 2011): var. affinis , (12)13–15(17) µm, var. armillata , (15)17–18(19) µm, and var. microspora , 8–10 µm. Peruvian specimens matched the description of var. armillata , with the spores ranging from 15–17 µm and with a conspicuous pale band ( Yamamoto 1998).
