Glaudopus. Quite a number of the spores were al rmal, and in 



one case one spore grew from the Bide of another which was the 

 only one attached to that basidium. The trama of the gills is 

 composed of narrow, parallel hyphae, "> micr. thick, hyaline to- 

 wards the pileus l»ui filled with a red homogeneous substance 

 toward the edge of the gills, where the hyphae terminate in in- 

 flated, sterile, oval or elliptical large cells; this coloring matter 

 gradually breaks up into refractive red globules. The trama of the 

 pileus is hyaline inward the gills, composed of interwoven narrow, 

 long hyphae, about <i micr. thick, which become narrower toward 



the surface Of the pileus and are filled with the red coloring matter. 



finally ending in tufts or fibrils which stand out from the surface 



ami are intensely scarlet red.

The grayish tint of the pileus is due to the minute, grayish floc- 

 cose squammules." When central-stemmed the species might be 

 mistaken fur a Naucoria. I have no1 collected it.
