167. GR. SCALPTURATA appears to be a very polymorphous species, both in external aspect 
and in the divisions and colour of the spores. A specimen from Dr. Montagne 
himself, collected at Cayenne, has the spores 8, small, oblong or subelliptical, 
5-celled, colourless; whilst Lindig. Lich. N. Gran. 54 has one immense cylin- 
drico-oblong fuscous murali-divided spore, more than three times longer than in 
our No. 330.
