THE AGARICACEAE OF MICHIGAN 



509. Hebeloma syrjense Karst. 



PILEUS 2-5.5 cm. broad, convex-expanded, firm, glabrous, viscid. 

 provided with a gelatinous, separable pellicle, even, rufous or brick- 

 red, fading to ochraceous-brown, margin at first incurved. FLESH 

 tonghish, pallid or tinged rufous-brown. GILLS adnate at first. 

 then emarginate, close, moderately broad, whitish tben rufous- 

 brown to cinnamon-brown, edge obscurely floccnlose. STEM 4-G 

 cm. lung. :'.."> nun. thick, subequal or attenuated downward, floccose- 

 8caly above, glabrescent below, tonghish, elastic, stuffed then hollow, 

 whitish, becoming sordid brownish below, even. SPOKES elliptical, 

 inequilateral, apiculate, smooth, 8-10.5x5-6 micr., pale rusty-cinna- 

 mon in mass. CYSTIDIA none. Sterile cells short, slender, cylin- 

 drical, on edge of gills. ODOR slight. TASTE slightly astringent. 



Gregarious or caespitose. On the ground in frondoSe woods. 

 Ann Arbor. September-October. Infrequent. 



This species has the appearance of a Cortinarius, but no cortina 

 is present in the young stage; on this account it is also to be dis- 

 tinguished from H. testaceum. The brick-red color, caespitose 

 stems and separable pellicle are characteristic features. The some- 

 wliat tough texture is also a marked character. When young, the 

 pileus is often bay-brown and in age may become irregular or 

 repand.
