6 34 THE AGARICACEAE OF MICHIGAN 



narrow, thin, not forked, white becoming dingy, edge serratulate. 

 STEM 6-12 cm. long, G-12 mm. thick above, tapering upward from 

 a bulbous base, sometimes equal and subbulbous, stuffed to hollow, 

 soft, whitish, at first covered by the fibrils of the veil, with scat- 

 tered brown squamules, terminating in a floccose-fibrillose, often 

 oblique and broken, rather evanescent ANNULUS. SPORES 

 elongated oblong, smooth, white, 7-9 x 2.5-3 niicr. ODOR and 

 TASTE not marked. 



(Dried: Cap, gills and stem alutaceous to wood-brown.) 

 Gregarious. On the ground or on very rotten wood in forests, 

 on flowerbeds, conservatories, etc. Ann Arbor, Bay View, New 

 Richmond. September. Frequent. 



Much the appearance of the next two species; separable with 

 certainty from L. friesii by its entire gills, from L. asperula by the 

 spores. The veil is composed of silky filaments woven into a mem- 

 brane which is at length lacerated vertically so as to appear like a 

 "cortina" of the genus Cortinarius. 



671. Lepiota friesii Lasch. 



Epicrisis, 1S3G-183S. 



Illustrations: See Hard's Fig. of L. acutaesquamosa, which it 

 imitates in appearance. 

 Marshall, Mushroom Book, 1902, op. p. 65. 



The description of the preceding species is sufficient for all the 

 characters except the following: GILLS very narrow, abundantly 

 forked, very crowded. SPORES 6-9 x 2 micr., narrowed at one 

 end, smooth, white, elongated-oblong to subfusiform. Sterile cells 

 on edge of gills as in the preceding species. Habitat, etc., same as 

 in L. acutaesquamosa. 



Ann Arbor, Houghton, Munising, New Richmond. 



The spores in our plants are narrower than in L. acutaesquamosa, 

 whicli may be a constant character. The forking of the crowded 

 -ills is very marked. The pointed warts are crowded on the disk, 

 or may be scattered over the entire surface of the pileus, and easily 

 rubbed oil".
