brown or umber; the stems of both are persistently white or whitish. 

 The spores are the same in the two species. On the other hand the 

 stem of I. destricta var. minor is rufous-tinged at maturity, 

 the pileus becomes normally more lacerated-scaly and usually there 

 is a shade of reddish in the brown color. The plants of the three 

 species average the same size. 



30 Inocybe excoriata Peck. A fairly large plant, with pileus 

 3-5 cm broad. Other species which have the general appearance of 

 it, differ in not possessing any cystidia. The pileus is not always 

 excoriate and not too much stress must be placed on this character. 

 The cystidia are thick-walled, fairly abundant and stout, and it is 

 possible that it is I. e u t h e 1 e s B. & Br. of Massee's monograph, 

 although not like specimens referred to I. eutheles by Bresa- 

 dola. 



34 Inocybe maritimoides Peck. There seems to be no other col- 

 lection in existence except the type. It is clearly distinguished by 

 its angular, non-nodulose spores and thin-walled, scattered cystidia. 

 When the spores are rolled over under the microscope the surface is 

 obscurely uneven; they are subrectangular to subquadrate in outline 

 when at rest. 



36 Inocybe umboninota (Peck) Massee. In the monograph, 

 Peck amends the original description in the 38th report, page 87, 

 by citing it as only " in part " the new conception. I shall therefore 

 use the specimens referred to in the monograph as the type. By 

 doing so, a number of difficulties connected with the identity of this 

 species disappear. An examination of several collections which must 

 be referred here, showed that the plants of this species vary larger 

 than the size given by Peck. The pileus is 1.5-5 cm broad, often 

 only a few of the large size in a collection. Nevertheless it must be 

 considered a medium to large size Inocybe. The spores have 

 the same characteristics as those of I. u m b r i n a Bres. but the 

 latter is a small plant, with very rimose caps, while the caps of 

 I. umboninota are scarcely rimose as a rule although tending 

 occasionally to become more so. The spores measure 6-8 x 4-6 

 micr., are angular-tuberculate, the tubercles not very distinct. In 

 stature it simulates I. asterospora Quel. 



38 Inocybe radiata Peck. This is apparently our nearest Ameri- 

 can relative of I. carpta Bres., but the pileus and stem of 

 I. radiata do not possess the lanuginose covering of Bresadola's 

 plants, and the spores of I. radiata are "generally narrowed 

 toward one end" (Peck), while those of soecimens from Bresadol? 

 which I examined are more rectangular in outlme. The size of t.h«*
