Discussion

Encalypta affinis is the only species of the genus in the flora area with papillae on the basal leaf cells. Specimens with short, excurrent costae and cuspidate leaf apices have been referred to var. affinis while the other extreme, costae ending below apex and leaves muticous, to var. macounii. This species could be confused with E. ciliata, also with a double peristome but with pitted instead of heavily papillose spores. Encalypta procera has a longer double peristome, granulate spores, and propagula on the stem tomentum.
