GYMNOMITRIUM ADUSTUM Nees 
Marsupella olivacea Spruce 
Frequent gn many of the hills in the Highlands to at 
least 3600 ft. alt., and also occurring, though rarely, in the 
lower subalpine regions to sea-level. It has only as yet 
been found in one locality in the Southern Uplands. When 
on the low ground of the subalpine region and for some 
distance up the hills, this plant is generally found on rocks 
and boulders as small loose tufts of an olive-green or 
yellowish-brown colour. On the higher parts of the hills 
the plant is most commonly found on bare soil, generally 
in rather compact, nearly black patches. Although this 
species is not rare on schistose rocks, it is found most 
commonly on granite, and has also been found on basalt. 
Fruit is generally present throughout summer and autumn.
