166 THE AGARICACEAE OF MICHIGAN 



ochraceous or ochraceous-yelloic. STEM 2-5 cm. long, 4-6 mm. 

 thick, white, spongy-stuffed then hollow, slender, equal or subequal 

 to subventricose, sometimes subclavate, even or obscurely rivulose. 

 SPOKES ochraceous. TASTE mild. ODOR none. 



Scattered or gregarious. In coniferous or mixed woods. So far 

 •reported only from northern Michigan. 



Like R. integra this has to be considered at present a composite 

 species, from which several species have, from time to time, been 

 segregated. According to von Post, a pupil of Fries, the master 

 himself included many forms which do not fit into his own descrip- 

 tion ; and Komell follows the Swedirsli tradition and refers to B. 

 cliamaeleontina all small forms with mild taste and ochraceous 

 s:ills not otherwise accounted for. "No subacrid forms are in- 

 eluded" writes Romell. Specimens with the caps a uniform red,, 

 rose colored, purplish, lilac, etc., and accompanied with a yellowish 

 tint, are always included; sometimes also, whitish, faded forms 

 must be placed here.

"PILEUS 1-2.5 cm. broad, thin, fragile, convex becoming plane 

 or slightly depressed in the center, covered with a viscid, separable 

 pellicle, tubercular-striate on the thin margin, variaMe in color^ 

 purplish, greenish-purple or olive-green with a browai or blackish 

 center, or sometimes purplish with a greenish center. FLESH 

 white. GILLS narrowed toward the stem, subdistant, equal, 

 rounded behind and nearly free, ventricose, whitish becoming pale 

 yellow. STEM 1-2.5 cm. long, equal or tapering upward, stuffed or 

 hollow, white. SPORES bright yellowish-ochraceous^ subglobose, 

 8-iO micr. TASTE mild." 



Its place of growth is only nmler lalsm fir. It has been reported 

 from Michigan, but the description given is that of Peck. The 

 important characters seem to be the bright yellow tinged spores. 

 It is separable from R. puellaris, "by the viscid cap, the gills rather 

 widely separated from each other and nearly free, the stem never 

 yellowish nor becoming yellow where wounded, and the spores bav- 

 in c: nn ochraceous hue."
