mon even on the streets of our larger cities.* It is commonly 

 eaten raw in salads. 



Montagjiites is a rare form, known only from Texas and New 

 Mexico in which the pileus is reduced to a simple, disc- like ex- 

 pansion of the end of the stipe. It is interesting only from its 

 relation to certain puff-balls. Bolbitiiis differs from both the 

 other genera in having rusty brown spores. The five American 

 species are mostly ^ nail and inconspicuous. 



4. Species with luaxy lamellae (Hygrophoreae). 



Three genera f make up this group. Of these Go?nphidiies 

 has black spores and decurrent lamellae. Nyctalis contains only 

 a single species, peculiar in its parasitic habit ; it grows usually 

 on the upper surface of the pileus of large species of Lactariiis. 



By far the greater number of the species heXongto Hygr op horns, 

 about thirty species being reported from this country. Some of 

 the species are highly colored, H. niiiiiatus being a bright red, 

 and H. psittaciniis having a green pileus and yellow stem. J 



5. Genera either ivith a milky juice, or with brittle adnate lam- 

 ellae and a fleshy stem. (Lactarieae.) 



According to Hennings three genera § belong here, but they 

 have usually been considered as forming only t^\ o, and it is per- 

 haps best to let them remain so for the present. 



Russula is so called from the predominance of species with a 

 red pileus and can be usually recognized by its brittle character, 

 added to its fleshy stem and usually adnate lamellae. A large 

 number of species are described from America, || but the limita- 



* Morgan (Jour. Cincinnati Soc. Xat. Hist. 6: 173-177J describes 

 thirteen species of Coprinus occurring in Ohio ; and Massee (Annals of 

 Botany, 10 : 1 2 3- 1 84. //. 10, 11. 1896) has given a monograph of the 

 entire genus. 



•)- Hennings {^loc. at.) also separates the species of HygropJiorus, which 

 have a slimy veil as a distinct genus, Liniaciiini. 



J Peck (Reg. Rep. 23: 112-114) describes seven of the species then 

 known to occur in New York, but many species have since been reported. 



\Loc. cit. 213-22I; he separates the genus Russulina from Russtila 

 based on the species with the spores tinged widi ochraceous. 



II Probably thirty species have been described and there are others. 

 Macadam (Jour. Mycol. 5 : 58-64, 135-141) attempted a .synopsis of our 

 species, but the work was discontinued after about twenty-tive had been 

 described.
