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

 in. long, .OOOIG to .0002 broad. 



Dead trunks and brandies of basswood, Tilia jimericana. 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. Tiie individual plants are also sometimes so 

 closely crowded that they appear ca3spitose. 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 margin 

 when moist, white when dry; lamellae very narrovj, linear, crowded, 

 decurrent, white, becoming cinnamon; spores globose, .0002 to X)QO)lb 

 in. broad. 



Old stumps and much decayed wQod. 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 FletirofKS peia- 

 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 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 26tli Report, 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. cC' 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 (jrayisli-white and striatu- 

 late on the margin when moist, wliite when dry ; lamelhe close, suh- 

 ventricose, rounded behind, white or whitiah, becoming brownish-fer- 

 ruginous ; spores f/Iobose, .00025 to .0003 in. broad. 



Variety 2)licatilis. 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 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-
