subdistant, rounded behind, radiating from a lateral or eccentric 
point, whitish, then ferruginous; spores subelliptical, .00035 to .0004 
in. long, .00025 to .0003 broad. 
Decaying wood, bark, ete., in damp, shaded places. Common. 
June to October. : 
This species, and C. herbarum appear to run together, and but for 
the marked difference in the size of their spores I should have united 
them. ‘The latter is not limited in its habitat to the stems of herbs, 
and the former sometimes, though rarely, occurs on them. C. her- 
barum is a smaller species with a thinner pileus, nearly always resupi- 
nate, and when reflexed, less densely tomentose. Its smaller spores 
especially distinguish it. Both appear to be closely allied to the 
European C’. chimonophilus, which seems to be distinguished by its 
a oe one elliptical” spores, and its few distant lamelle attenuated 
ehind. 
Crepidotus fulvotomentosus, P*. 
Tawny-tomentose Agaric. 
Pileus eight to twenty-four lines broad, scattered or gregarious, 
suborbicular, reniform or dimidiate, sessile or attached by a short, 
white-villose tubercle or rudimentary stem, hygrophanous, watery- 
brown and sometimes striatulate on the margin when moist, whitish, 
yellowish or pale ochraceous when dry, adorned with small, tawny, 
hairy or tomentose scales ; lamelle broad, subventricose, moderately 
close, rounded behind, radiating from a lateral or eccentric white vil- 
lose spot, whitish becoming brownish-ferruginous ; spores elliptical 
often uninucleate, .0003 to .0004 in. long, .0002 to .00025 broad. 
Decaying wood of poplar, maple, etc. Common. June to Oc- 
tober. 
A pretty species, corresponding in some respects to the European 
C. calolepis, but much larger and with tawny, instead of rufescent 
scales. ‘The cuticle is separable and is tenacious though it has a hya- 
line gelatinous appearance. The pileus is subpersistent, and specimens 
dried in their place of growth are not rare. 
Crepidotus dorsalis, P#. 
Dorsal Agaric. 
Pileus eight to fifteen lines broad, sessile, dimidiate or subreniform, 
plane or slightly depressed behind, with a decurved substriate margin, 
slightly jfidrillose-tomentose, reddish-yellow; \amelle close, ventricose, 
rounded behind, radiating from a lateral white villose spot, yellowish, 
then brownish-ochraceous or subferruginous; spores globose, .00025 in. 
broad. 
Decaying wood. Sprakers and Adirondack mountains. June and 
September. Buffalo. G. W. Clinton. 
The tomentum of the pileus is more dense and conspicuous about 
the point of attachment, where it sometimes forms minute tufts or 
scales. ;
