Part 3, 1917] AGARICACEAE 193 
Bolbitius fragilis Fries, Epicr. Myc. 254. 1838. Reported from various parts of North 
America. The specimens I have seen represented a variety of things and had to be disregarded. 
Bolbitius tener Berk. Outl. Brit. Fungol. 183. 1860. Reported from New York, Indiana, 
and elsewhere, but the specimens so named do not appear to be distinct from Galerula crispa. 
Bolbitius titubans (Bull.) Fries, Epicr. Myc. 254. 1838. (Agaricus titubans Bull. Herb. 
Fr. pl. 425, f. 1. 1788.) Reported from various parts of the United States, but I have seen 
no American specimens. ‘The spores are described as incarnate-salmon-colored, which would 
place the species among the PLUTEANAE. 
Bolbitius vitellinus (Pers.) Fries, Epier. Myc. 254. 1838. (Agaricus vitellinus Pers. 
Syn. Fung. 402. 1801. Not A. vifellinus Batsch, 1783.) Reported from North Carolina 
by Schweinitz.

Pileus thick, fleshy, putrescent, solitary, tomentose; lamellae concrete with the pileus, 
long-decurrent, anastomosing behind; spores ochraceous, much elongated; stipe central or 
nearly so, fleshy; veil none.
