CANTHERELLEAE 



Fruit-body fleshy or submembranous. Stem central or lateral. 

 Gills thick, obtuse on edge, fold-like or ridge-form, usually forked, 

 narrow. Veil none. 



I*>\ the inclusion of Trogia and several tropical or subtropical 

 genera, the group is extended by some authors to include sessile 

 and reviving or arid plants. As Limited above the group approaches 

 Thelepharaceae on the one side, the genera Clrtocybe and Hygro 



his on the oilier. The genus Dictyolus Quel, belongs here, bu1 

 no species have been found within the state. Ii is characterized by 

 plants having ;i lateral stem arising from the larger mosses, and by 

 vein-like, forked gills. D. retvrugus is probably a native of the 

 state. The group includes Cantherellus, Dictyolus and Nyctalis. 



Nyctalis Fr. 



I Prom the Greek. wyx } night, referring to the black color of the 

 host-mushroom. | 



Wnite-spored ; chlamydo-spores abundant; gills thick, distinct, 

 obtuse on edge; stem central; parasitic on other Agarics; veil none. 



Fleshy, putrescent, no1 large-sized mushrooms, developing on the 

 pileus and stem of the fruit-bodies of Russula, Lactarius, Cantherel- 

 lus, etc., after the latter have become well developed or are partially 

 decayed. The gills and basidiospores in our species are often 

 dwarfed or entirely undeveloped. The propagation of the plant is 

 instead, dependent on the presence of secondary spores which are 

 formed in abundance over large parts of the surface of the plants. 

 These spores are elliptical, brownish, long-spiny, r_' I s micr. in 

 diameter. They are formed from the loosened hyphae of the ^u-- 

 face of the pileus, etc., which break up Into chains of spores, and 

 because of this method of formation, are called chlamydospo
