margin, whitish or various shades of cream color and yellow. 
Lamellae broad, adnate, sometimes with a broad shallow sinus, 
decurrent in lines on the stem, white becoming purple black. 
Stem stuffed with a pith, equal or enlarging and somewhat 
bulbous at the base, white or cream color, ffocculose below the 
annulus, viscid with the pellicle cracking as on the pileus. 
Annulus slight and evanescent, near the middle of the stem. 
Spores elliptical, dark purple, 10xT6^. 
This species is not so common as the folowing Stropharia 
semiglobata. It is distinguished by the more expanded pileus, 
the stuffed and more floccose stem, the larger size, larger spores 
and plane not clouded gills. In our observation these distinc¬ 
tions do not always hold good. The plants photographed have 
all the marks of Stropharia stercoraria except that the gills are 
clouded. We have found Stropharia semiglobata with spores 
as large as any ascribed to Stropharia stercoraria. Lloyd’s pho¬ 
tograph of Stropharia semiglobata in Hard’s, mushrooms fig. 
260 resembles ours. We take Atkinson’s illustration, fig. 30 to 
be more typical Stropharia semiglobata. 
Stropharia semiglobata, Batsch. 
This is the most common species of Stropharia. It is found 
everywhere on dung and manured ground. Illustrations are 
numerous. Atkinson, Mushrooms, fig. 30 is a good photograph 
of the species. It resembles Stropharia umbonatescens, PL 
LXV A. except that the pileus is exactly hemispherical. 
Pileus fleshy in the center, hemispherical, not expanding, 
smooth, even on the margin, viscid, light yellow. Lamellae, 
broad adnate, whitish and becoming mottled purple brown or 
black. Stem equal, smooth, fistulose, ^viscid, light yellow, 
sometimes slightly enlarging at the base. Annulus a fibrous 
ring stained with spores. Spores elliptical 8-—9x13—IP* or 
larger.
