(417 ) 
slightly depressed: lamellae adnate: spores white: veil 
none: stipe central, solid, woody. 
Type, Lentinus cubensis B. & C. Jour. Linn. Soc. Bot. 
10: 302. 1868. (Syll. 5: 605.) 
This is a small genus distinguished from Lentodium solely 
by the absence of a veil. I£ this organ should be discovered 
by the study of young specimens, then this name would be- 
come a synonym under that genus. 
36. ANTHRACOPHYLLUM Cesati, Myc. Borneo 3. 
1879. 
Sporocarp fleshy, putrescent: pileus dimidiate: lamellae 
from a lateral point, unequal: spores black: veil none: stipe 
none or very short and lateral. 
Type, A. nigrita (Lév.) Kalchbr. (Syll. 5: 1139.) 
There is some doubt as to the validity of this genus. 
Patouillard (Tax. Hymén. 146) says that the spores are color- 
less. The single species referred to it is not known to me. 
37. MELANOTUS Pat. Tax. Hymén. 175. 1g00. 
Sporocarp fleshy, putrescent: pileus dimidiate; lamellae 
radiating from a lateral point: spores purplish-brown: veil 
none: stipe none. 
Type, Crepddotus bambusianus Pat. (Syll. 11: 63.) 
No species of this genus has been reported from North 
America, but an undescribed one occurs in Cuba. 
38. TAPINIA (Fries) Karst. Hattsv. 452. 1879 
Sporocarp fleshy but firm, putrescent: pileus dimidiate or 
resupinate: lamellae from a lateral point, often anastomosing, 
separable from the pileus: spores ochraceous-brown: veil 
none: stipe none. 
Type, Paxillus panuoides Fries. (Syll. 5: 889.) 
Besides being distinguished bythe separable, anastomosing 
lamellae, these plants are usually larger and tougher than 
those of the next genus. 
39. PHIALOCYBE Karst. Hattsv. 415. 1879. 
Crepidotus (Fries) Quél. (homonym). 1872. Type, C.
