CLASSIFICATION OF ACAItlCS 185 



PILEUS 3-7 cm. broad, broadly convex, then expanded, obtusely 



depressed, sometimes broadly ambonate, very viscid, run/inn dull 

 orange to yellowish on dish-, paler yellowish toward the olwe on 

 greenish margin, in age variegated yellowish-olivaceous-brown, 

 at first decorated ton-aril margin by wedg< shaped, creamy to vine 

 ceous, ftbrillose, detersile } delicati scales, concentrically arranged, 

 the outermosl forming an interrupted fringe al the edge of the 

 pilens, glabrescenl Lu age, margin even, a1 firsl incurved. FLESB 

 soft, moist, thick on disk, thin on margin, yellowish-white. GILLS 

 adnate, rounded behind or sinuate, often seceding or Bubdecurrenl 

 in age, rather broad behind, tapering anteriorly, close to crowded, 

 at the very first creamy-buff, soon grayish-fuscous, finally dark 

 olive purplish-gray, edge white-flocculose. STEM 3-6 cm. long, 3-5 

 mm. thick, slender, rigid-tough, subequal, curved, solid-fibrous .with- 

 in, in age hollow, ftbrillose and dotted with small, recurved scales 

 up to tin- evanescent annulus, yellowish above, becoming dull red- 

 dish-brown below. VEIL rather well -developed at the fust . vary- 

 ing white to vinaceous, lilac or purplish-tinged, floccose-fibrillose. 

 SPORES oval or short oblong, 6-7.5x3.5-4.5 micr.. smooth, dark, 

 fuscous-brown with a slight purplish tinge in mass. CYSTIDIA 

 numerous on sides and edge of gills, subventricose below, lanceolate 

 above, about 55 micr. long. 



Solitary to subeaespitose. On logs, sticks, dead branches, etc., 

 frondose and mixed coniferous W Is. 



Marquette, New Richmond. Ann Arbor, etc. Throughout the 

 State. July-October. Bather frequent. 



This species is distinguished from all the other Flammulas by 

 the peculiar color of the gills and spores: the tint of gray and 

 purple which these possess may easily lead the student into plac- 

 ing it among the purple-spored genera. The other characters, 

 however, ally it to the genus Flammnla. The colors of the pileus 

 are, furthermore, quite variable, but there is nearly always an 

 olivaceous tint present, especially on the margin when young. The 

 pelliculose cap is usually glutinous and when fresh dotted with the 

 triangular, hairy, appressed scales. It is apparently indigenous 

 to America.
