Abstract

The genus Glyphothecium Hampe (Ptychomniaceae) is treated herein as comprised of three species. Glyphothecium sciuroides (Hook.) Hampe is reported for the first time to occur in the New World, growing sympatrically with G. gracile (Hampe) Broth. in Patagonia. The distribution of G. gracile in parts of the world other than southern South America is questioned. Morphological distinctions between G. sciuroides and G. gracile are clarified for the first time. The disjunct distribution of G. sciuroides is correlated with the distribution of a known phorophyte, Nothofagus.
