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

 eaten raw in salads. 



Montagnites 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. Bolbitius differs from both the 

 other genera in having rusty brown spores. The five American 

 species are mostly small and inconspicuous. 



4. Species with waxy lamellae (HYGROPHOREAE). 



Three genera f make up this group. Of these Goinphidiits 

 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 Lactarius. 



By far the greater number of the species belong to Hygrophorns, 

 about thirty species being reported from this country. Some of 

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

 and H. psittacinus having a green pileus and yellow stem.j" 



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

 ellae and a fleshy stem. (LACTARIEAE.) 



According to Hennings three genera belong here, but they 

 have usually been considered as forming only two, 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. Nat. Hist. 6: 173-177) describes 

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

 Botany, 10 : 123-184. //. /o, //. 1896) has given a monograph of the 

 entire genus. 



f Hennings {loc. cit.} also separates the species of Hygrophorus^ which 

 have a slimy veil as a distinct genus, Liinacium. 



\ 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. 213-221; he separates the genus ftiissitfina from Aussit/a 

 based on the species with the spores tinged with ochraceous. 



| 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-five had been 

 described.
