Harper—Species of Hypholoma . 
1161 
determined by weather conditions. A whole series of them 
can probably be found. 
g. Veil annulate. 
In these plants the veil makes a ring on the stem instead of 
clinging to the margin of the pileus. They are of course de¬ 
scribed in the genus Stropharia. Such variations between an¬ 
nulate and appendiculate in the character of the veil often occur 
in the praecox-dura group in the genus Pholiota and elsewhere. 
Peck describes such a form as Stropharia irregularis, Torr. 
Pull. Jan. 1900, pp. 16-—17. It had a slight annulus soon 
breaking into fragments and disappearing. The author ex¬ 
pressed the opinion later that it is a form of Hypholoma in- 
certum. 
Murrill in Mycologia, Hov. 1912, pp. 301—302, has de¬ 
scribed a form with a much more persistent annulus, Stropharia 
longistriata of which he says “Similar to Hypholoma appendieu- 
latum in general appearance but always furnished with a thick 
persistent annulus.” 
h. Doubtful forms. 
Hypholoma atrofolium Pk. Torr. Bull. Oct. 1896, p. 417 is of 
doubtful affinities. Mtirrill suggests that it may belong to the 
genus Psathyrella. 
Hypholoma subuquilum Bann. 1ST. Y. State Mus. 44 pp. 70— 
71 shows nothing distinctive according to the brief description 
except the small spores 4x5/*.
