216 THE AGARICACEAE OF MICHIGAN 



Solitary or gregarious upon duug or various kinds of debris. 

 This is one of the earliest species of Coprinus to appear in the sprint 

 The long cylindrical or narrowly conical pileus distinguishes this 

 plant from the various forms of C. fimetwrius, which usually appear 

 a little later in the season. 



This may be the C. lagopus of various authors. 



197. Coprinus lagopides Karst. 

 Karsten, Hatts., 1, 535. 

 Illustrations: Massee, Ann. Bot., Vol. 10. PL 10, Figs. 20-22. 



PILEUS 4-7 cm. broad, very thin, companulate, sulcate, grayish, 

 disk livid, ornamented with free white scales joined by hairs. 

 GILLS subcrowded, narrow, remote, black. STEM up to 17 cm 

 high, white, floccose, hollow, equal. SPORES Q-S x 5-6 micr., apic- 

 ulate. Upon very rotten wood in forest. 



Found once at Bay View. We have found this plant in New 

 York also. 



198. Coprinus jonesii Pk. 



Peck, Bull. Torr. Bot. Club 22, p. 20G, 1895. 



PILEUS 2.5-5 cm. broad, at first blunt, or truncate, becoming 

 campanulate or broadly convex, submembranaceous, grayish, buff 

 at apex, covered at first with white or tawny-cinereous floccose 

 scales which wholly or partly disappear with age, striate, margin 

 revolute and splitting. GILLS crowded, linear, free, whitish be- 

 coming black. STEM 5-9 cm. long. 4-7 mm. thick, equal' or 

 shghtly tapering upward, minutely floccose, hollow, white. 

 SPORES 7.5-8.5 x micr., broadly elliptical. 



Fragile, sometimes caespitose. Found upon the wall in a cellar 

 at Ann Arbor. Peck says "This species is closely related to C 

 fimetarius of which it might easily be considered a variety but it 

 is easily distinguished by the truncate apex of the young pileus, 

 the differently colored pileus and smaller spores." It grew on what 

 appeared like nncracked hard and dry plaster of the wall
