Russula ochracea Fr. 



Pileus pale ochraceous, soft, convex, then expanded and de- 

 pressed, margin coarsely striate, pellicle thin, viscid, disk usually 

 becoming darker. 



Lamellae slightly adnexed, broad, scarcely crowded, ochra- 

 ceous. 



Stem ochraceous, slightly wrinkled longitudinally, stuffed, 

 soft. Taste mild. 



Spores globose, echinulate, ochraceous, 10 to 12 /u,; pileus 7.5 

 cm, broad; stem about 3.5 cm. long, 10 to 14 mm. thick. 



Grassy places in deciduous woods. Glen Ellyn. June. Stem 

 ochraceous but paler than the pileus; taste mild; flesh very pale- 

 ochraceous; lamellae pale-ochraceous with a slight greenish tint. 



CANTHARELLUS. 



Hymenophore continuous with the stem, descending un- 

 changed into the trama; lamellae thick, fleshy-waxy, fold-like, 

 somewhat branched, obtuse at the edge. Fleshy, membrana- 

 ceous fungi, without a veil. Spores white. 



Not hygrophanous 1 



Hygrophanous 2 



1. Plant yellow; lamellae concolorous, 



stem solid C. cibarius. 



Plant orange; lamellae darker, stem 



stuffed C. aurantiacus. 



2. Plant dingy or brownish when moist; 



stem hollow C. infundibuliformis. 



Cantharellus cibarius Fr. 



Pileus fleshy, firm, convex, becoming expanded or slightly 

 depressed, glabrous, yellow, the margin at first involute, then 

 spreading and often wavy or irregular. 



Lamellae narrow, thick, distant, decurrent, branched or anas- 

 tomosing, yellow. 



Stem firm, glabrous, solid, yellow. 



Spores elliptical, pale yellowish, 7.5 to 10 /x. long. Pileus 2.5 

 to 10 cm. broad; stem 2.5 to 10 cm. long, 6 to 12 mm. thick. 



Ground in woods, throughout our district. July to October. 



Plants collected at Glencoe in 1902, have exactly the characters 

 of C. minor Pk., except that the spores are 10 x 7 p., agreeing 

 substantially with those of C. cibarius. 

 Cantharellus aurantiacus Wulf. (Plate VII.) 



Nearly orange-color. Pileus fleshy, soft, depressed, some- 

 what tomentose. 



Lamellae close, straight, dichotomous, of a rather deeper color. 



Stem stuffed, unequal. 



Pileus 5 to 7.5 cm. broad; stem 5 cm. long. 



Among decayed leaves on and about the base of stump, Lisle. 

 August. The pileus is occasionally eccentric. Spores elliptical, 

 6x4/x.
