Encalypta rhaptocarpa is widely distributed in the northern part of the flora area. It is somewhat similar to E. alpina, but differs in leaf shape and has a much longer excurrent costa, a peristome, and an entire or erose base on the calyptrae. Encalypta rhaptocarpa could be confused also with E. vittiana by the strongly ribbed and red color on the capsule, however E. vittiana has a shorter awn and fringed calyptrae. The peristome of E. rhaptocarpa generally presents as single row of reddish, broadly lanceolate teeth. Careful examination of some specimens reveals a preperistome of very short, stubby projections ringing the outside of the main teeth.
