MARSUPELLA 101 
Nevis. It occurs as thin purple patches on steep wet 
rocks. Male plants are common; fruit has not been 
observed. 
Herr Kaalaas agrees that the Ben Nevis plant is cer- 
tainly M. Boeckii. I cannot see that it differs from our 
M. Stableri. Mr Pearson, to whom I sent specimens from 
Ben Nevis, also had no doubt that they were the same 
species as M. Stableri.

MARSUPELLA USTULATA Spruce 
Frequent in many parts of the Highlands, from sea-level 
on the west coast to 3900 ft. alt. in Mid Perth. Grows in 
small, compact, dark-brown to nearly black patches on soil, 
also as scattered patches on boulders and rocks, especially 
on schist and granite. It doubtless occurs in many other 
parts of the Highlands than those recorded, also in the 
hilly district of Kirkcudbright, but has been overlooked. 
It is of similar appearance to M. Sprucei, and cannot be 
distinguished from it in the field. Fruit is usually present 
from June to October.
