Tribe [. CANTHARELLEAE 
Hymenium covering obtuse lamellae-like folds of the sub- 
stance of the pileus. 
1. PLICATURA Peck, Ann. Rep. N. Y. State Mus. 24: 
75. 1872. 
Reviving, persistent: pileus sessile or resupinate, tough: 
lamellae obtuse, fold-like: spores white or hyaline: veil 
none: stipe none. 
Type, Zrogia Alni (Peck) Sacc. (Syll. 5: 637.) 
The sessile species of 7rogva and Xerotus as given in the 
Syloge should be sought here. 
2. XEROTINUS Reichenb. Consp. 14. 1828. 
Nerotus Fries. 1828. Not Aerotus R. Brown. 1810. 
Reviving, persistent: pileus tough, stipitate: lamellae 
obtuse, fold-like, usually furcate: spores white or hyaline: 
veil none: stipe central, thick, homogeneous with the pileus. 
Type, Xerotus afer Fries. (Syll. 5: 632.) 
Fries first used the name erotes in Syst. Orb. Veg. 78. 
1825, but without citing species. Inthe H/enchus he changed 
it to .Yerotus, which is only a different ending for the same 
word. According to our rules Reichenbach was correct in 
renaming it. The sessile species of the Syoge are here 
excluded. 
3. DICTYOLUS Quél. Enchr. Fung. 139. 1886. 
Corniola S. F. Gray. 1821. Not Cornzola Adans. 1763. 
Leptoglossum Karst. 1879. Not Leptoglossa DC. 1841. 
Putrescent : pileus eccentric, dimidiateor resupinate, fleshy : 
lamellae obtuse, fold-like: spores white or hyaline: veil 
none: stipe lateral or wanting. 
Type, Cantharellus muscigenus (Bull.) Fries. (Syll. 5: 
495-) 
As here defined this includes Cantharellus, § Pleuropus 
and § Resupinatus, of the Sylloge.
