few plants of these violet-gilled species are usually found, and they 

 all appear to be very rare. 



23 Inocybe subochracea (Peck) Massee. I would include in 

 this, var. b u r t i i Peck, since the greater or lesser development of 

 the veil is the only difference between them and depends on condi- 

 tions for growth. This species is sharply characterized among the 

 ochraceous or yellowish species by the abundant thick-walled, slender 

 cystidia, especially numerous over the whole surfaces and edges of 

 the gills. These cystidia are tinged yellow, and in dried specimens 

 this characteristic is brought out still more, especially by the use of 

 potash solution. In nearly all other species, the cystidia are hyaline. 

 The subcuneate shape of the spores is also a helpful character, 

 although not so sharply marked. 



24 Inocybe serotina Peck. This is a large whitish or yellowish- 

 white species of sandy regions. The spores are elliptical. The 

 cystidia are few and hard to find, short, 45-55 x 18-22 micr. Peck 

 does not mention them. The species is closely related to the genus 

 Hebeloma, but no viscidity was reported on the pileus. 



25 Inocybe minima Peck. The type was collected by Simon 

 Davis in Massachusetts. Peck found it also in New York State. 

 The pileus is minutely fibrillose or lanuginose, recalling the kind of 

 covering present on the pileus of I . i n f e 1 i x , but the spores and 

 cystidia are quite different. The spores measure slightly longer than 

 given by Peck. 



26 Inocybe comatella (Peck) Massee. Quite small and occur- 

 ring on rotten wood. The spores measure 6-7 (8) x 3-4 micr., as 

 given by Massee ; this is smaller than noted by Peck. The cystidia 

 are abundant and thick-walled. The hairs of the pileus appear as 

 hyaline bundles of hyphae under the microscope. 



27, 28, 29 Inocybe eutheloides Peck ; I. pallidipes E. & E. : 

 and I. destricta var. minor Kauff., are closely related and kept 

 apart with difficulty in the dried condition. The pileus of all three 

 are more or less rimose, the extent of rimosity depending on 

 weather conditions. This series of closely similar species includes 

 I. eutheles Berk., which apparently has thin-walled cystidia. 

 I. destricta var. minor has both the thin-walled and thick- 

 walled type, the former predominating on and near the edge of the 

 gills, but mixed with the other type. I. eutheloides and 

 I. pallidipes have thick-walled cystidia of the usual appear- 

 ance ; when growing, I. eutheloides has a fawn colored cap, 

 while that of I. pallidipes varies from light brown to darker
