This plant is closely related to the preceding one from which I have 

 seniirated 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 c^spitose. It is possible that inter- 

 mediate forms may yet be found that will connect these. 



Crepidotus applanatiis, 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 hycrrophanous, waterv-white and striatulate on the margin 

 when moilt, white when drV; lamella very narrow, linear, crowded, 

 decurrent, white, becoming cinnamon; spores globose, .0002 to .0002o 



in. broad. t i i. o * 



Old stumps and much decayed wood. Common. July to beptem- 



It is very variable in the shape of the pileus, but it is commonly 

 cither cuneate or spathulate. It closely resembles Pleurofus jjefa- 

 loides in this respect as well as in the narrow crowded lamella^ 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 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. (& 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 llab- 

 ellate, nearly plane, sometimes depressed behind, sessile or pro onged 

 behind into a short white tomentose rudimentary stem or tubercle, 

 glabrous, hygrophanous, umterij-white or (/nti/ish-wJttfc and striatu- 

 late on the margin when moist, 2uhite when dry: lamella' close si<I>- 

 .ventricose, rounded heldnd, wliite or whitish, becoming brownish-ler- 

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



'Yavletvplicafilis. Pileus coarsely plicate on the margin. 



Decayfng wood in damp shaded places. Common. June to bep- 



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 b> t he 

 thin margin than it is by the thicker disk. The stnations are .sonu-
