Reiner-Drehwald, M. Elena Pôrto
The new species Lejeunea perpapillosa is described and illustrated, based on two collections from north-eastern Brazil (Pernambuco and Bahia states). It is characterized by strongly papillose leaf cells, highly bifid underleaves, and caducous and fragmenting leaves and underleaves. Differences of the morphologically similar Lejeunea phyllobola are discussed.
