Mycologia 



margin ; lamellae free, crowded, rather broad, plane, white ; spores 

 ovoid, regular, smooth, hyaline, 5X3-5/*; stipe white, hollow, 

 subglabrous, tapering upward from an enlarged base, 4 cm. long, 

 2-5 mm. thick; annulus large, white, persistent, near the middle 

 of the stipe. 



Type collected on the ground in a banana field at Santiago de 

 las Vegas, Cuba, June 17, 1904, F. S. Earle 75. This species is 

 related to L. colimensis, but is quite distinct. 



2. Lepiota colimensis sp. nov. 



Pileus convex, regular, solitary, not umbonate, 1.5 cm. broad, 

 5 mm. high ; surface dry, white, delicately floccose, not scaly, the 

 center concolorous ; lamellae free, white; spores broadly fusiform, 

 smooth, pure hyaline, 7-8 X 3.5—4.5 ^ ; stipe long, slender, white 

 with an avellaneous tint, cepaeform at the base, 4 cm. long, 2 mm. 

 thick above, 7 mm. thick below ; annulus superior, large, white, 

 persistent, apparently fixed. 



Type collected on the ground in an orchard at Colima, Mexico, 

 500 m., January 3, 1910, W. A. & Edna L. Murrill 618. A small 

 specimen of what appears to be the same species was collected in 

 a moist forest at Motzorongo, Mexico, 400 m., January 15, 1910, 

 W. A. & Edna L. Murrill 1023. 



3. Lepiota tepeitensis sp. nov. 



Pileus convex to expanded, slightly umbonate, 3 cm. in diam- 

 eter ; surface white, uneven, fuliginous at the center, adorned with 

 fuliginous, imbricate scales, the remains of the cuticle; lamellae 

 free, white, broad, rather crowded; spores ellipsoid, smooth, pure 

 hyaline, usually uninucleate, 7 X 4> ; stipe white, glabrous, taper- 

 ing upward, 4 cm. long, 3 mm. thick; annulus slight, evanescent. 



Type collected in humus in a moist virgin forest along the 

 Tepeite River, near Cuernavaca, Mexico, 2300 m., December 28, 

 1909, W . A. & Edna L. Murrill 522. The general appearance of 

 the plant suggests Lepiota ianthina Cooke, first found in green- 

 houses at Kew Gardens, but the disk and its radiations are fulig- 

 inous instead of dark-violet. 



4. Lepiota flavodisca sp. nov. 



Pileus thin, conic to subexpanded, the center remaining conic in 

 form, solitary, 2 cm. broad ; surface white, minutely crested, long 

 and deeply striate, becoming plicate on drying, the center flavous,
