Mycologia 



nexed, crowded, of medium width, subconcolorous ; spores broadly 

 ellipsoid, obtuse at both ends, smooth, dark-purplish-brown under 

 the microscope, 7x5^; stipe slender, fragile, tapering upward, 

 enlarged at the base, glabrous, silky, hollow, concolorous but 

 slightly paler, 7 cm. long, 2-3 mm. thick; annulus distant 2.5 cm. 

 from the pileus, ample, persistent. 



Type locality : Chalmitte, New Orleans, Louisiana. 



Habitat : On the ground in wet woods. 



Distribution : Vicinity of New Orleans, Louisiana. 



Collected by F. S. Earle, No. 116 (type), September 8, 1908; 

 also on September 7, 1908, No. 101. A thin, fragile plant re- 

 sembling certain species of Drosophila, but having an ample, per- 

 sistent annulus. The color of the pileus in dried specimens varies 

 from avellaneous to umbrinous or fuliginous ; the stipe and annulus 

 being nearly white.

 face glabrous, moist, hygrophanous, becoming striatulate, sub- 

 cinnamon-colored when moist, ochraceous when dry; lamellae ad- 

 nate, broad, yellowish to umbrinous ; spores globose to ellipsoid, 

 brownish-black, 12-17 x 6-Q/jl; stipe tough, short, stuffed or hol- 

 low, dry, flocculose, pallid, 2.5 cm. or more long; annulus lacerate, 

 fugacious; veil often appendiculate. 



Type locality : Sweden.

I have excellent material collected by Romell and myself in 

 Sweden, in which the spores are elongate-ellipsoid, smooth, opaque, 

 yellowish under the microscope, reaching 17 x 9 /a. Harper de- 

 scribes and figures what he considers S\ submerdaria Britz., and 

 says that Morgan refers it to S. merdaria as a variety. Kautfman 

 finds this species in Michigan and follows Karsten in placing it in 

 Psilocybe, since the stipe is described as tough.
