CUtocybe inversus Scop. This species closely resembles the last, 
from which it is here distinguished by the reddish color of the gills 
and the smaller, more globose spores. Lanzi, Funghi Roma, PI. 95, 
fig. 3, gives a good figure of these forms. On the ground. Tornado, 
August, Kohlberg. 
Clitocybe laccata Scop. Common on the ground in woods, early 
and late. Mile Bluff, June, Mauston; Melchior’s, November, Algoma. 
Clitocybe maxima Gaert. & Meyer. The pileus grows to be 25 
cm. broad and the stipe 20 cm. high. Such forms are figured by Cooke, 
Illust., Pi. 135. Under dense growth of young oak and pine, Dodge’s, 
Crossville, near Mauston. 
Clitocybe multiceps Pk. Clusters growing in the woods are more 
slender than those found along street curbing. Insects do not seem 
to infect the plants and they remain several days in a fresh condition 
after being gathered. August, Fish Creek. 
Clitocybe socialis Fr. In Sphagnum swamps with Boletinus palus - 
ter, Blahnik’s, November, Algoma. 
Collybia acervata Fr. The shining stems are dark brown, four or 
five being bound together at the base by a mass of felt-like hairs. On 
decayed wood, Warner”s grove, September, Algoma. Peck vid. 
Collybia confiuens Pers. Among leaves, Krohn’s lake, August, 
Algoma. Peck vid. 
Collybia dryophila (Bull.) Fr. The species is variable as to form 
and color. The commonest form is figured by Holland, Atlas Champ., 
PI. 48, fig. 102, Some specimens have white gills and greasy, hygro- 
phanous caps. These might be called C. butyracea. Cf. Cooke, Illust., 
PI. 143. On the ground among leaves, and cespitose near old logs, 
August, Foscora; Krohn’s Lake, Algoma. 
Collybia fusipes Fr. The most characteristic features of the spe¬ 
cies are the ventricose stipe and the manner in which the gills pull 
aw'ay from the stem in groups attached to a collar. This is well 
shown by Buliiard, Hist. Champ., Pis. 36 and 106, p. 612; Paul., Icon. 
Champ., PI 50 figs. 1. 2; Bolt., Hist. Fung., PI. 129. Most other figures 
show much longer stems which taper downward several inches. Tim- 
ble’s woods, October. Algoma. 
Collybia lacunosa Pk. Specimens o.5—2 cm. broad, 2-4 cm. high, 
golden yellow throughout with the exception of the whitish gills, were 
found frequently on coniferous logs. The plants dry with little loss of 
color or form. The species is rather tough for one of this genus. 
Specimens at the New York Botanical Garden, very similar to ours, 
having the same scabrous stipe, have bden called Omphalia scabriuscula 
Pk. Krohn’s Lake, August, Algoma. Peck vid. 
Collybia laxipes Fr. This is a slender, symmetrical little plant 
with a velvet-coated stipe and flesh-colored pileus which is viscid in
