MASTIGOPHORA Nees 
MasticopHorRA Woopstt (Hook) Nees 
This rare Atlantic species is confined to the west side of 
the Highlands, though not ending in the western watershed, 
as it extends slightly over that into the East Highlands 
when that province approaches the west coast. This species 
extends from Dumbarton to Sutherland, and is found in 
some quantity on several of our hills from 1600 ft. to 
2300 ft. alt. In one locality in Argyll it occurs at the low 
level of 1000 ft. alt. Its usual habitat is moist rock ledges, 
but it is found also on steep grassy or heathery slopes. It 
forms large reddish-brown patches, the cclour being very 
similar to that of Ptilidiwm ciliare, and is either unmixed 
or among other species, especially Scapania ornithopo- 
divides, S. gracilis, Bazzania tricrenata, Jamesoniella 
Carringtoni, and Anastrepta orcadensis. Inflorescence 
has not been seen.
