Doubtful and Excluded Species 



Agaricus (Psathyra) pholidotus Mont. Syll. Crypt. 126. 1856. 

 Collected in grassy ground at Columbus, Ohio, by Sullivant. De- 

 scribed as fugacious with scaly disk, reminding one of some species 

 of Coprinus, but the gills are blackish-purple. I have not seen the 

 types. 



Atylospora corrugis (Pers.) Fayod, Ann. Sci. Nat. VII. 9: 376. 

 1889. Specimens from Bresadola greatly resemble the types of 

 A. umbonata, but Peck says his species is much darker, striatulate, 

 and atomate, with a less glabrous and more slender stipe and 

 broader spores; also the umbo is very prominent and becomes 

 white on drying. 



Psathyra obtusata Fries, Syst. Myc. 1: 293. 1821. Reported 

 by Kauffman from Michigan, occurring infrequently on very rot- 

 ten wood. I have not seen his specimens. 



Psathyra per simplex Britz. Bot. Centralb. 77 : 436. 1899. Re- 

 ported by Kauffman as rare on dead wood in hemlock woods in 

 Michigan. He says it differs from P. obtusata in the size of its 

 spores and the characteristic spreading of the margin of the pileus. 



Psathyra polytrichopkila (Peck) Sacc. See Deconica. 



Psathyra roseolus (Clements) Sacc. Syll. Fung. 14: 154. 1899. 

 (Gymnochilus roseolus Clements, Bot. Surv. Neb. 4: 23. 1896.) 

 Collected on the ground on bluffs of the Missouri River, at Belle- 

 vue, Nebraska. Pileus hemispheric or convex, 1^2.5 cm. broad, 

 glabrous or nearly so, wrinkled, vinous when wet, incarnate when 

 dry; lamellae slightly remote, purplish-cinnamon-colored; spores 

 ellipsoid, dark-purple, 12-13 x 7-8^; stipe tall, fragile, fistulose, 

 shining, glabrous, farinaceous-granular at the apex, 4-8 cm. long, 

 2 mm. thick. I have not seen the types.
