No. 23. The Glistening Coprinus. A cluster growing in a lawn 
where a cottonwood tree has been removed. 
gills, at first white, change through brownish purple to black and in 
rather dry weather they shrivel and dry up instead of melting into 
ink. 
The Glistening Coprinus occurs mostly during late spring and 
early summer, but is not infrequently found during the autumn fol¬ 
lowing rainy weather. 
Inky Cap (Coprinus atramentarius). 
This is a somewhat larger mushroom than the glistening co¬ 
prinus and is readily distinguished by the shape and color of the caps. 
It usually occurs in grassy places where the soil is rich, many often 
crowded together, the short stems being almost hidden from view. 
The caps are from one to two inches high, oval or egg-shaped, 
sometimes slightly indented at the top, and of a gray or brownish 
gray color. The caps have fine lines extending to the margin, some 
of them being quite deep grooves and in consequence the margin i * 
apt to be rather irregular. It leaves a rather prominent ridge where 
it was attached to the stem. The surface of the cans is frequently 
quite scaly, due to the breaking up of the surface during growth, 
while in other forms the longitudinal striations or fine grooves are 
alone present. The caps when open assume a flattened bell-shape 
with the margin usually upturned and rolled back. The stems are 
white, smooth above and somewhat scaly or rough below the ridge¬ 
like ring and are comparatively short at first, but lengthen as the 
caps expand, often reaching a height of six inches. Tt is oftenest 
found during summer and autumn
