The Mycologic Flora of the Miami Valley^ 0. 75 



58. A. FiLOPES, Bull. — Pileus membranaceous, obtusel3', campanu- 

 late, expanded, striate. Stipe filiform, flaccid, rather fragile, glabrous; 

 the base hairy, rooting. Lamellae free, lanceolate, close, white. 



In woods among the fallen leaves, simple and solitary. Pileus \-^ 

 in. broad, stipe nearly 2 in., besides the root. The color brownish or 

 livid gra}', rarely white. 



B. The plant when cut or broken exuding a colored juice. 



59. A. H^MATOPUS, Pers. — Csespitose. Pileus somewhat fleshy, cara- 

 panulate, obtuse; the margin denticulate. Stipe rigid, white, pulveru- 

 lent, when broken exuding a dark red juice. Lamellae adnate, whitish. 



Common in woods upon logs; recognized at once by the dark-red 

 juice when broken. Pileus ^-1 in. in diameter, the stipe 2 in. or more. 

 The color is commonly a dark reddish or purplish, sometimes paler. 

 Our plant seems to be the same as the British plant described by B. & 

 Br. in the Handbook, but neither seems to me to be the plant of 

 Fries. The latter is even, the lamellae of one color, etc. Fries' figure 

 shows no striae. 



Note. — The Mycenas like the Tricholomas appear to be remarkably 

 scarce in the Miami Valley. Yet being mostly very small plants, it is 

 quite likely several species have been overlooked. Leaianus, galericu- 

 latus and hcemntopus are common enough, other species must be rare, 

 and the individuals few in number. 



Subgenus VIII. — Omphalia, Fr. 



Spores white. Pileus somewhat membranaceous, more or less um- 

 bllicate. Stipe cartilaginous, usually thickened upward, and expanded 

 into the pileus. Lamellae truly decurrent. 



A. Margin of the pileus at first inflexed. 



a. Lamellae narrow, close, 60-G2. 

 6. Lamellae broad, distant, 63-65. 



B. Margin of the pileus straight. 



c. Lamellae broad, 66, 67. 



d. Lamellae narrow, 68. 



A. Pileus dilated from the first, the margin inflexed. 

 a. Lamella> narrow, close. 



60. A. CHRYSEUS, Peck.— Yellow. Pileus plane or somewhat de- 

 pressed, umbilicate, striatulate, minutely scaly. Stipe nearly glabrous, 

 stuff-ed or hollow, sometimes curved. Lamellae close, rather narrow.
