ARMILLARIA APPENDICULATA. 
Pileus broadly convex, glabrous, whitish, often tinged with 
ferruginous or brownish-ferruginous on the disk, flesh white or 
whitish ; lamellae close, rounded behind, whitish ; stem equal or 
slightly tapering upward, solid, bulbous, whitish, the veil either 
membranous or webby, white, commonly adhering in fragments 
to the margin of the pileus; spores subelliptical, .0003 in. long, 
.0002 broad. Pileus 2~4 in. broad; stem 1.5-3.5 in. long; 5-10 
lines thick. :

The general appearance of this species is suggestive of Zitcho- 
loma album, but the presence of a veil separates it from that 
fungus and places it in the genus Armillaria. The veil, however, 
is often slight lacerated or webby and adherent to the margin of 
the pileus. 
CLITOCYBE TARDA. 
Pileus fleshy but rather thin, easily splitting when old, but firm 
when young and fresh, convex becoming nearly plane or some- 
what centrally depressed, sometimes slightly umbonate, glabrous, 
hygrophanous, brown when moist, grayish or grayish-brown when 
dry, the margin at first deflexed or incurved, flesh white, in- 
odorous; lamellae subhorizontal, moderately close, rather fragile, 
adnate or slightly decurrent, often eroded on the edge, at first with 
a pale violaceous tint, becoming whitish; stem short, equal or 
tapering downwards, solid, fibrillose, colored like the pileus; 
spores elliptical, .0003 in. long, .00016 broad. Pileus 1-3 in. 
broad ; stem about I in. long, I—3 lines thick. 
Ground in greenhouses. Lynn, Massachusetts. December. 
Mrs. A. P. Doughty. : 
The species is referable to the second section of the tribe Orbi- 
formes.. The stem, when viewed by the aid of a lens, appears to 
be longitudinally and interruptedly rimulous from the separation 
of the fibrils. These are somewhat reticulately connected as in 
the stem of C. cyathiformis. The lamellae easily split transversely, 
and sometimes separate from the pileus at their inner extremity. 
There are two forms. The darker colored one may be taken 
as the typical form. It is firmer, more regular, and under a lens 
sometimes appears to be minutely innately fibrillose> The other 
may be designated as 
CLITOCYBE TARDA PALLIDIOR. 
Pileus paler, more fragile and irregular, more apt to be cen- _
