mollis (Schaeff.) Quél. (Syll.5: 877.) Not Crepidotus S.F. 
Gray. 1821. 
Derminius (Fries) Schroet. (metonym). 1889. Type, 
Crepidotus scalaris Fries. (Syl. 5: 878.) 
Sporocarp soft, fleshy, putrescent: pileus irregular, often 
dimidiate or resupinate: lamellae neither separable nor anas- 
tomosing : spores ochraceous-brown or cinnamon: veil none: 
stipe eccentric, lateral or wanting. 
Type, Crepidotus eprbryus Fries. (Syll. 5: 881.) 
The use of the generic characters adopted in the corre- 
sponding series of white-spored species would result in con- 
siderable segregation. For the present it seems more con- 
venient to hold the species together. 
40. CLAUDOPUS (W. G. Sm.) Gillet, Champ. Fr. 1: 
426. 1878. 
Sporocarp fleshy, putrescent: pileus irregular, dimidiate 
or resupinate: lamellae neither separable nor anastomosing : 
spores pink or salmon: veil none: stipe eccentric, lateral, 
or wanting. 
Type, C. vardabzl’s (Pers.) Gillet. (Syll. 5: 733.) 
Here again a strictly consistent treatment would require 
needless segregation. 
41. UROSPORA Fayod, Ann. Sci. Nat. Bot. VII. g: 328. 
1889. 
Phyllotus Karst. Hattsv. 92. 1879. Not Phyllota Benth. 
1837. (Type, Pleurotus porrigeus (Pers.). (Syll. 5: 374)-) 
Sporocarp fleshy or membranous, putrescent: pileus ses- 
sile, at first resupinate: lamellae from a central or eccentric 
point: spores white: veil none: stipe none. 
Type, Pleurotus striatulus (Fries). (Syll. 5: 382.) 
With age some of the larger species become pronouncedly 
dimidiate and might easily be confused with the next genus. 
At first, however, all are clearly resupinate. As here used 
this genus corresponds to Pleurotus § 3, HMesupinati, sub- 
sections * and ***, of the SyMoge.
