tose, suberect, shining, smoothish, rigid and fragile when dry, pale- 
greenish or greenish-grey ; lacinie lineari-attenuate, short, roundly 
compressed, usually much divided towards the apices, pulverulento-

This looks as if related to R. farinacea, but the structure of the cortex 
and the chemical reaction, as well as the general habit and place of 
growth, show its affinity io be rather with R. scopulorwm, to which it 
holds the same relation as R. farinacea has to R. calicaris. Sometimes 
it spreads extensively over the substratum, while at other times it occurs 
only in small tufts. It is very rarely fertile in Great Britain, the spermo- 
gones having the spermatia as in the preceding species.
