Harper—Species of Pholiota of the Great Lakes Region. 477 
us is squamose. Striations or ridges on the annulus have been 
noted in Pholiota aurea, Pholiota rugosa, Pholiota togularis, 
var. filaris and in Stropharia coronilla. The ridges in our 
plants are very marked. 
Pileus fleshy, convex becoming, plane, obtuse, even, slightly 
viscid when moist, smooth or squamose with innate darker col¬ 
ored fibers, yellowish. Flesh white. Lamellae close, adnate 
or slightly notched, becoming dark ferruginous brown with 
white eroded edges. Stem short, enlarged below, white floccose, 
solid becoming stuffed or hollow. Annulus thick with deep 
radiating ridges on the upper surface. Spores ferruginous 
brown, elliptic, 3—4x5—6 /*. 
The plant photographed is a very large specimen. 
Note. Pholiota johnsoniana, Pk., is another species of this type. It 
is somewhat smaller than Pholiota caperata, has a similar thick an¬ 
nulus and even white stem. It was described and figured by Peck, 
N. Y. State Mus. Rep’t 23 p. 98 and PI. III. It is also described and 
photographed by Atkinson, Mushrooms, p. 153. Reported from Michi¬ 
gan by Kauffman. 
2. Large plants with a membranous annulus. 
Pholiota howeana, Pk. (?). 
The plant photographed was found growing on the ground 
in open damp woods at Glencoe Ill., in June. 
Pileus heavy, fleshy, convex to plane or depressed when 
old, smooth, moist, even, dirty whitish or yellowish becoming 
dark colored. Flesh thick and white. Lamellae broad, ven- 
tricose, adnate, whitish becoming rusty brown with spores. 
Stem white, much thickened towards the base and fusiform 
rooted, slightly enlarging towards the apex, scaly and shreddy 
below the collar. Annulus broad, membranous, entire. Spores 
4—5x8—9 /*. 
The plant is close to Pholiota howeana, Pk., ~N. Y. State 
Mus. Rep’t 26, pp. 59-00 (Stropharia howeana) and Mus. 
Bull. 122 p. 147. 
Pholiota ventricosa, Earle, Bull. Y. Y. Bot. Garden 1902 
p. 341, is another species based on plants very similar to ours.
