whitish becoming pink ; stem somewhat fiexuous, equal, fibrillose, 
hollow, sometimes compressed and canaliculate, brown, a little 
paler than the pileus, with white mycelium at the base ; spores 
subglobose, angular, 10-12 fx in diameter, commonly uninucleate.

The species is remarkable for its somber coloring and its prom-
