Stropharia caesiospora sp. nov. 



Pileus 4-9 cm. broad, convex, obtuse, chamois to honey-yellow (Ridg.), 

 subviscid, even, firm or slightly elastic, margin somewhat crenate-lobed ; flesh 

 white, rather thick and compact, thin on margin ; gills crowded, narrow, 

 adnexed-emarginate, at length rounded behind, heterophyllous, drab to hair- 

 brown or ashy-gray ; stem 4-9 cm. long, equal or slightly bulbous at the base, 

 whitish, 6-12 mm. thick, slightly lacerate above the annulus, stuffed to solid, 

 fibrillose-glabrescent ; annulus persistent, membranous, flocculose below, striate- 

 ridged above, becoming gray from the spores ; spores minute, 5-6 X 3-4 fi, 

 ovoid, smooth, tinged purplish-cinereous under microscope, ashy in mass with 

 a tint of purple ; cystidia none, except few, inflated, sterile cells on edge of 

 gills ; odor slight. 



Gregarious, on the ground among debris in chestnut and conifer mixed 

 woods, Elkmont, Tennessee, September, 1916. The color of the half-mature 

 gills is similar to that of S. depilata Fr., but paler. The annulus has the 

 markings of S. coronilla Fr. and of S. bilamellata Pk., which differ in spore- 

 size. It is near to the description of 5". obdurata, which Ricken considers 

 identical with 5". coronilla. It was found a number of times.
