the base; spores eubelliptical, brownish -ferruginous, .00025 to .0003 

 in. long, .00016 to .0002 broad. 



Dead trunks and branches of basswood, Tilia Americana. East 

 Berne, Albany county. August. 



Tliis 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 cajspitose. It is possible that inter- 

 mediate forms may yet be found that will connect these. 



Crepidotus applanatus, Fr. 



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 mai'gin 

 when moist, white Avhen dry; laniellse very narrow, linear, crowded, 

 decnrrent, 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 Pleiirotiis jjefa- 

 loides in this respect as well as in the narrow crowded lamellae and 

 flattened stem-like base. As in that species and others of this genus, 

 the pileus quickly be;comes convolute in drying, unless it is pUiced 

 under pressure. The striations of the thin margin are often retained 

 in the dried plant. In the 26th Eeport, our specimens were errone- 

 ously referred to C. nephrodes, B. & C, from which they differ in the 

 glabrous pileus and crowded linear lamella. 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, B. S 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 fiab- 

 ellate, nearly plane, sometimes depressed bebind, sessile or prolonged 

 behind into a short white tomentose rudimentary stem or tubercle, 

 glabrous, hygrophanous, watery-ivhiie or grayish-white and striatu- 

 late on the margin when moist, white when dry ; lamella? close, siib- 

 ventricose, rounded heliind, white or whitish, becoming brownish-fer- 

 ruginous ; spores globose, .00025 to .0003 in. broad. 



Varietj 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 pilous and much broader lamella 

 rounded behind. In drying, the moisture is retained longer by the 

 thin margin than it is by the thicker disk. The striations are some-
