Notes
No further specimens of this species appear to have been found, despite the type-locality being on the doorstep of a past centre of systematic botanical work. According to Fries, in E. & P. Pf., ed. 2, 17a (2): 156 (1959), it differs from the other 4 species in its glabrous connective-appendage.
