true Hypholoma lacrimabundum in Europe are not more than 
4—5X7—9 /i. Murrill in Mycologia, May, 1915 p. 116 pi. CLVIII 
2, gives a good figure of Hypholoma velutinum but calls it Hypho¬ 
loma lacrimabundum (Bull) Quel. He appears to be of the opinion 
that Fries’ plant was an old scaly form of the one illustrated by 
Bulliard. 
Note 2. Hypholoma delineatum Pk., N. Y. State Mus. Bull. 
150 p. 83 is placed in the Hypholoma velutinum group by the 
author. Dr. Peck said it could be easily mistaken for Hypholoma 
rugocephalum from which it was to be separated by its more 
narrow obtuse and smooth spores. Dr. Dodge sent me a dried 
plant which he considered Hypholoma delineatum after examina¬ 
tion of Peck’s specimens. A photograph of it is shown in pi. 
XXI D. Both Peck’s description and Dodge’s specimen differ 
from the plants in the Hypholoma velutinum group in the smooth 
stem and broad membranous annulus as well as in the smooth, 
not opaque and not apiculate, spores. Nor have the gills in the 
dried specimen turned black. In all these characters the plants 
agree with members of the Pholiota erebia group as described in 
the note, Vol. XVII p. 1163 and pi. LXXXIV. Peck also calls 
attention to the rugose pileus with radiating ridges on the margin 
and to the habitat on both rotten logs and the ground both 
features of forms in the Pholiota erebia group. Furthermore the 
spores in the dried specimen are larger than those described by 
Peck, 5—6X12—14 m instead of 4—6X8—10g, both of which 
measurements are found in forms I have included in the Pholiota 
erebia group. It is probable therefore that Hypholoma deline¬ 
atum Pk. belongs to the Pholiota erebia group. 
THE HYPHOLOMA APPENDICULATUM-CANDOLLEANUM 
GROUP 
In vol. XVII, pis. LXXX-LXXXI11 of these Trans¬ 
actions I published illustrations of five forms belonging to 
this group. Hypholoma candolleanum, leucotephrum, cuti- 
fractum, longipes and incertum. I here add illustrations of 
typical Hypholoma appendiculatum, a form similar to leu¬ 
cotephrum and the annulate form described as Stropharia 
irregularis Pk. or Stropharia longistriata Murr. The spores 
in all the forms are of the same size and character 4—6x7 
—12m. 
1. Hypholoma appendiculatum Bull. PL XXII ABC. 
Hypholoma appendiculatum was very abundant at 
Geneseo., Ills., during the summer of 1915. The plants 
grew in lawns and pastures, preferring the vicinity of stumps 
and buried roots. They varied much but the most typical
