Schistidium occidentale (E. Lawton) S.P. Churchill, a species described in 1967 as Grimmia occidentalis
E. Lawton, was distinguished as a separate taxon in
1940. It was described as G. alpicola Hedw. var. rivularis
(Brid.) Wahlenb. fo. acutifolia Grout. The
identity of this taxon with S. occidentale
is confirmed, its name is lectotypified, and some
diagnostic characters of this form are illustrated. Species
of Schistidium Bruch & Schimp.
subg. Canalicularia
Ochyra are reviewed and a
key to their determination is provided.
