lieueosporae 



A. crenula'ta Pk. Pileus thin, broadly ovate, becoming convex 

 or nearly plane and somewhat striate on the margin, adorned with a few 

 thin whitish floccose warts or with whitish flocculent patches, whitish or 

 grayish, sometimes tinged with yellow. Lamellse close, reaching the 

 stem, and sometimes forming decurrent lines upon it, floccose crenulate 

 on the edge, the short ones truncate at the inner extremity, white. 

 Stem equal, bulbous, floccose mealy above, stuffed or hollow, white, 

 the annulus slight, evanescent. Spores broadly elliptic or subglobose, 

 7.5101". long, nearly as broad, usually containing a single large nucleus. 



Pileus 2.5-5 cm - broad. Stem 2.5-5 cm. long, 6-8 mm. thick. 



Low ground, under trees. Eastern Massachusetts. September. Mrs. 

 E. Black ford and George E. Morris. 



The volva in this species must be very slight, as its remains quickly 

 disappear from the bulb of the stem. The remains carried up by the 

 pileus form slight warts or thin whitish areolate patches. The annulus 

 is present in very young plants, but is often wanting in mature ones, in 

 which state the plant might be mistaken for a species of Amanitopsis. 

 Its true affinity is with the tribe to which A. rubescens belongs. As in 

 that species, the bulb soon becomes naked and exhibits no remains of 

 the volva. It is similar to A. farinosa also in this respect, but quite 

 unlike it in color, in the adornments of the pileus and in the character 

 of its margin, which is even in the young plant and but slightly striate 

 in the mature state. Its dimensions are said sometimes to exceed those 

 here given, and it is reported to have been eaten without harm and to 

 be of an excellent flavor. I have had no opportunity to try. Peck,
