lamellae. No measurements of that species are recorded, but 

 as figured (Krombh. $1. 6i,f. S, o) it is smaller and darker

 lamellae all equal, interveined and subanastomosing near the 

 stipe, subsinuate, broad, subplane, white to cream yellow; 

 spores pale yellow, globose, rough with sharp conical projec- 

 tions, 7-9 ,«; stipe variable in size, 5-11 x 1^2-3 cm., equal,

 tomosing lamellae. It belongs to the section Fragilcs.

 ing pine trees ; pileus 7-8 cm., convex, obtuse, reddish-brown,

 to subglabrate, margin even, subappendiculate with the 

 fibrous remnant of the ruptured veil; lamellae subsinuate, 

 crowded, rather broad and subventricose, edge thin but en- 

 tire, pale brown becoming dark cinnamon, spores bright fer-
