h. Pileus striatulate, at least when wet. 



3. DECONICA BULLACEA Bulliard, Herb. Fr. 1791. 

 Cooke, Illustr. 608. 



Pileus fleshy, hemispheric then expanded, glabrous, at length 

 ■umbonate, striatulate to the middle, tawny-bay, alutaceous when 

 dry. Stipe short, fistulous, equal, fibrillose, yellowish, at the 

 base brown-ferruginous. Lamellae adnate, triangular, plane, 

 close, brown-ferruginous ; spores elliptic, 7-9 x 5-6 mic. 



Growing on manure and in rich soil. Michigan, Kauffman. 

 Pileus 2-2.5 cm. in diameter, stipe 2-3 cm. long, 2-3 mm. thick. A 

 smaller plant with smaller spores than D. coprophila. 



4. DECONICA SCATIGENA B. & C, Fungi Cub. 1867. 



Pileus convex, yellow-brown. Stipe glabrous above, at the 

 base tomentose. Lamellae broad, adnate by a tooth ; spores 

 minute. 



Growing on manure. Cuba, Wright. Pileus 6-y mm. in 

 diameter ; stipe 2 cm. high, 2 mm. thick. The minute spores 

 distinguish this species from D. bullacea. 



5. DECONICA SUBVISCIDA Peck, 41 N. Y. Rep., 1887. 



Pileus thin, subconical then convex or nearly plane, often 

 slightly umbonate, glabrous, hygrophanous, pale chestnut or 

 reddish tan color, slightly viscid when moist and striatulate, pal- 

 lid or dull bufif when dry. Stipe equal or tapering downwards, 

 fibrillose, hollow, brownish toward the base, paler above. La- 

 mellae broad, subdistant, adnate or subdecurrent, at first whitish 

 then brownish ferruginous ; spores ovoid, brown, 7-8 x 5 mic. 



Growing on horse manure and in rich soil. New York, Peck. 

 Pileus 6-12 mm. in diameter; stipe 2-3 cm. long, 2 mm. thick. 

 The species is closely related to D. bullacea ; it is gregarious and 

 in wet weather appears in great abundance and in successive 

 crops. 



II. AMMOPHILAE. Groiving in sand and gravel in 

 woods and open places. 



a. Growing among mosses. 



6. DECONICA POLYTRICHOPHILA, Psathyra poly- 

 trichophila Peck, 30 N. Y. Rep. 1877. 



Pileus thin convex, or subcampanulate, glabrous, fragile, 

 hygrophanous, brown and striatulate wdien moist, bufif or dull
