free gills and the pileus is covered by a reddish gray furfur- 
aceous coat. Morgan transfers it to the genus Pilosace.

About half of the species of Hypholoma reported from the 
United States are in this section. All except Hypholoma hy¬ 
dro philmn which is reported from Michigan by Kauffman ap¬ 
pear to belong to a single group. We have named the group 
after the two common European species Hypholoma candollea- 
num and Hypholoma appendiculatum both of which are re¬ 
ported from this country. 
The Hypholoma Candolleanum-Appendiculatum Group. 
Hypholoma candolleanum Fr. PI. LXXX. 
Typical plants of the species Hypholoma Candolleanum Er. 
are shown in PI. LXXX. Compare also Cooke’s Illustration PI. 
546. They grow scattered or in clusters on the ground or on 
very rotten logs in the borders of woods and bushy places. The 
plants photographed were collected at Sumner, Washington. 
The plants are acorn shaped at first as in D, becoming cam¬ 
panula te and expanded, often with the margin split and up¬ 
turned. The surface usually appears smooth but there is a 
slight universal veil which under favorable weather conditions 
appears as separating floccose scales on the pileus. This is 
true of all the species in the group. A few such flocci are seen 
on the young plant in D. The margin of the pileus is usually 
even but sometimes appears finely striate with long lines. Es¬ 
pecially is this true of the dried plants PI. LXXXIII B. The 
striate margin is noted in a number of plants in the group. The 
partial veil is a thin woven membrane seen also in I), which 
clings in patches to the margin of the pileus as it expands. This 
veil is characteristic and gives the name to the section. The 
gills, seen in C, are close and rather narrow, slightly ventricose, 
rounded and adnexed or broadly sinuate behind with a slight 
tooth connecting with lines down the stem. The gills are violo- 
ceous when young becoming purple brown in age and this is the
