Bucklandiella sudetica (Funck) Bednarek-Ochyra & Ochyra
Synonym: Racomitrium sudeticum (Funck) Bruch &. Schimp. in B.S.G.
Racomitrium sudeticum (Funck) Bruch &. Schimp. in B.S.G. forma kindbergii Frisvoll
Special status: NONE
Recognition: This is a dark, smallish racomitrium that grows on rocks high in the mountains. Its short urn is a good clue. It has a leaf margin that is bistratose in one cell row and a costa that is mostly 3 stratose in the lower and middle parts. The best way to distinguish it from Bucklandiella occidentale is by the adaxial costa shape in the distal half of the leaf. The abaxial side of the costa is round and smooth in Bucklandiella sudetica while there is a shallow, irregular groove on the abaxial side of the costa in Bucklandiella occidentalis. The hairpoint is usually short, less than 0.5 mm in Bucklandiella sudetica and longer than that in Bucklandiella occidentalis.
Distribution: Widspread but infrequent, in the mountains probably mostly above 5,000 feet in Oregon.
Comments: This is a critical species with a wide range of variability. I have found it only once in Oregon, on the east slope of the Cascades in Klamath County.
