Type, Pleurotus applicatus (Batsch). (Syll. 5: 379-) 
This is Pleurotus § 3, Resupinata, subsection **, of the 
Sylloge. It differs from Scytinotus solely in the gelatinous 
upper layer of the pileus. It is a well-marked group easily 
distinguished from the other segregates of Pleurotus by the 
tough, reviving pileus. 
22. HEMICYBE Karst. Hattsv. 248. 1879. 
Sporocarp tough, coriaceous, reviving: pileus dimidiate : 
lamellae from a lateral point, thin, lacerate: spores white or 
hyaline: veil none: stipe short, lateral or none. 
Type, Lentinus urs¢nus Fries. (Syll 5: 608.) 
This corresponds to Lenittnus series B, Pleurotz, of the 
Sylloge. 
23. PANELLUS Karst. Hattsv. 96. 1879. 
Rhipidium Wallr. Fl. Crypt. Germ. 2: 742. 1833. Not 
fetpidium Trinn. 1820. 
Sporocarp tough, coriaceous or woody, reviving: pileus 
dimidiate: lamellae from a lateral point, thick, entire, sub- 
obtuse: spores white or hyaline: veil none: stipe lateral or 
none. 
Type, Panus stypiicus (Bull.) Fries. (Syll. 5: 622.) 
This is Panus §**, of the Sy/oge. It is difficult to find 
technical characters by which to separate this from Hemz- 
cybe, but the two types are sufficiently distinct. 
24. PANUS Fries, Epicr. Myc. 396. 1838. 
Sporocarp coriaceous, often thick and fleshy, reviving: 
pileus irregular, convex or depressed: lamellae adnate or 
decurrent: spores white or hyaline: veil none: stipe eccen- 
tric, usually stout, solid. 
Type, P. farneus Fries. (Syll. 5: 614.) 
As here defined the genus excludes the dimidiate and resu- 
pinate sections. It differs from the segregates of Lents- 
nus solely in the irregular pileus and eccentric stipe. The 
character of the lamellae, whether thin and lacerate or thick 
and entire, cannot be here used as a generic character. 
Many species of Pocillaria have entire lamellae.
