tawny and finally clay colored when dry and the characteristic 
broad, rough, apiculate, opaque spores. It is the only form 
in the group which I have collected. 
Pileus 2'—3 inches broad, fleshy, from ovate to campanulate 
and expanded, obtusely iimbonate, even on the margin, covered 
when young with a veil of appressed matted fibers becoming 
glabrate, hygrophanous, lurid when young becoming tawny and 
finally clay colored or isabelline. Flesh very thin, concolor- 
ous. Lamellae adnexed, easily separating, broad, not 
crowded, pallid with the edge white, becoming dark brown, 
black dotted. Stem 2—4 inches long, up to Vo inch thick, hol¬ 
low, equal, covered with a fibrous coat like that on the pilous 
below the annulus, white tomentose above. Colored like the pileus 
but lighter. Veil of fibrous tufts adhering chiefly to the mar¬ 
gin of the pileus, whitish becoming black with the spores. 
Spobes ellipsoid, oblique or irregular, apiculate, fuscous, not 
pellucid, 5x9-— 10/*. Basids 7 —8x8—25/*. Cystids 9x40/*. 
NOTE. Hypholoma rugocephalum Atk. is fully described and 
illustrated in “Mushrooms” p. 30 and PI. 8. Hypholoma boughtoni 
Pk. and Hypholoma delineatum Pk. are described in N. Y. State Mus. 
Bull. 150 pp. 82—-84. The former is figured in Bull. 139 PL II, 
figs. 1—7. 
IV. Flocculosa. 
As stated above the group is not a natural one. There is a 
whole series of forms in which the pileus is covered with sepa¬ 
rating floceose scales in the Hypholoma candolleanum-append- 
iculatum group and Hypholoma sublateritium also has a scaly 
form. We have no photographs of the plants which remain in 
the section. 
Hypholoma artemesiae Pass, is reported in Farlow’s index. 
Hypholoma aggregatum Pk. and var. sericeum Pk. are de¬ 
scribed in H. Y. State Mus. Bep’t 46 p. 106 ! and Bull. 54 p. 
972, PI. 79, figs. 8-—14. The plants are densely tufted and 
grow about the base of stumps. They are said to resemble Hy¬ 
pholoma candolleanum but are not hygrophanus. Hypholoma 
aggregatum is distributed in Shear’s H. Y. Fungi Ho. 13. 
Hypholoma olivaesporum Ell. & Ev. is a small plant about 1 
inch high and y 2 inch broad growing among sphagnum. It has
