This looks as if related to li. farinacca, but the structure of the cortex 

 and tlij chemical reaction, as well as the general habit aud place of 

 growth, show its ailiiiity lo be rather with li. srupulorum, to which it 

 holds the same relation as R. farinacea has to R. calkaris. 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.
