The form photographed, which grows in the open on grass culms, has 
much shorter stem (2-3cm.) than the usual form in woods (var. setipes), 
which has stem 0 to 9 cm. long. On a very wet day I have seen in the 
open the pileus almost white with a dark center and expanded so 
tensely as to become striate. Normally it is darker color and not 
striate. 
Some recent European writers are disposed to use Bulliard's 
name “cauticinalis” for this plant, but personally we do not favor dis¬ 
placing a well established name in common use for a plant, solely on 
the grounds of “priority.” 
101— COLEYBIA STIPITARIA VAR. ROBUSTA P. T. 
It is stated (Myc. Notes, 43) that Collybia 
zonata seems to be an enlarged edition of C. stipi- 
taria in fact it has all the characters excepting 
size. I am perfectly familiar with both plants 
growing around Cincinnati, and have never in 
this locality seen any forms connecting them. 
This summer, in northern Michigan, growing on 
fallen cedar limbs in a swamp, I found a plant 
that I could not refer to either. It seemed to be 
exactly intermediate. We present a photograph, 
and it is not necessary to further describe it. 
The description of the color and zonate hairs of 
either stipitaria or zonata covers it. For the coiijbi. sUp’SrmV robust., 
present we call it a form of stipitaria, as (Natural size.) 
between the two it is closer to this plant in size, though it might not 
be thought so from the figures we present. Our figure of zonata is of 
a very small specimen. 
102—COLEYBIA ZONATA. 
This plant has been described in these notes (vide 
No. 43.) The opinion of Prof. Bresadola expressed 
that this plant is a large form of stipitaria is 
strongly confirmed in my mind by since finding an 
intermediate form in Michigan. Still the normal 
form of the two plants are so widely different in size, 
that I would call them by different names. 
103—COLLYBIA HARIOLORUM. 
Pileus white, thin, smooth, expanded or depressed, 
margin obscurely striate. Gills very numerous, 
close, narrow, free. Stipe pale, even, hollow, cov¬ 
ered below with long, white, loose, woolly hairs. 
It grows usually several in a cluster in woods 
ground. It is not common. The stipe is not as 
firm as C. dryophila. In drying the hairs of the 
stipe mat down. A peculiarity of the plant is the
