Grimmia pseudo-anodon Deguchi, previously known only from Peru, is reported as new to Bolivia. The specimens are from packets labelled as Coscinodon trinervis, collected by Herzog in 1911. Grimmia pseudo-anodon is distinct by its non-plicate leaves and straight, centrally attached seta. This is a range extension of some 300 km and an elevational increase of about 1000 m
