' Dead trunks and branches of basswood, Tilia Americana. East 
Berne, Albany county. August. 
This plant is closely related to the preceding one from which I have 
separated it because of its larger size, smaller spores and stem not 
thickened at the base. The individual plants are also sometimes so 
closely crowded that they appear czespitose. It is possible that inter- 
mediate forms may yet be found that will connect these. 
Crepidotus applanatus, £7. 
Flattened Agaric. 
Pileus very thin, six to twelve lines long, four to ten broad, vari- 
able in shape, suborbicular, reniform, cuneiform or spathulate, plane 
or convex, sometimes slightly depressed behind, sessile or prolonged 
behind into a short compressed white-tomentose stem-like base, gla- 
brous, hygrophanous, watery-white and striatulate on the margin 
when moist, white when dry; lamelle very narrow, linear, crowded, 
decurrent, white, becoming cinnamon; spores globose, .0002 to .00025 
in. broad. 
Old stumps and much decayed wood. Common. July to Septem- 
ber. 
It is very variable in the shape of the pileus, but it is commonly 
either cuneate or spathulate. It closely resembles Plewrotus peta- 
loides in this respect as well as in the narrow crowded lamelle and 
flattened. stem-like base. As in that species and others of this genus, 
the pileus quickly becomes convolute in drying, unless it is placed 
under pressure. The striations of the thin margin are often retained 
in the dried plant. In the 26th Report, our specimens were errone- 
ously referred to C. nephrodes, B. & C., from which they differ in the 
glabrous pileus and crowded linear lamelle. This last character dis- 
tinguishes it from all our other Crepidoti. It is gregarious and the 
pileus is often stained by the spores. 
Crepidotus malachius, BD. & C. 
Soft-skinned Agaric. 
-Pileus thin on the margin, thicker behind, eight to twenty-four 
lines broad, varying from reniform or suborbicular to cuneate or flab- 
ellate, nearly plane, sometimes depressed behind, sessile or prolonged 
behind into a short white tomentose rudimentary stem or tubercle, 
glabrous, hygrophanous, watery-white or grayish-white and striatu- 
late on the margin when moist, white when dry; lamelle close, swb- 
ventricose, rounded behind, white or whitish, becoming brownish-fer- 
ruginous ; spores globose, .00025 to .0003 in. broad. 
Variety plicatilis. Pileus coarsely plicate on the margin. 
Decaying wood in damp shaded places. Common. June to Sep- 
tember. 
This resembles the preceding species in color and habit, but it is 
easily distinguished by its broader pileus and much broader Jamelle 
rounded behind. In drying, the moisture is retained longer by the 
thin margin than it is by the thicker disk. The striations are some-
