Clitocybe centralis n. sp. 



PLATE C, fig. I6-20 



Pileus thin, broadly convex or nearly plane, slightly umbilicate, 

 ■glabrous, hygrophanous, pale grayish brown and faintly striatulate 

 on the thin margin, with the center brown or brownish when moist, 

 grayish white when dry, flesh whitish, taste and odor farinaceous ; 

 lamellae thin, close, adnate or slightly decurrent, whitish ; stem 

 short, equal, stuffed or hollow, fibrous, colored like the pileus ; spores 

 minute, elliptic, .00024 of an inch long, .00012 broad. 



Pileus 6 to 15 lines broad ; stem 1 to 1.5 of an inch long, 1 to 2 

 lines thick. Gregarious. In woods among fallen leaves. Essex and 

 Warren counties. September and October. 



The brown or brownish umbilicus of the pileus affords a con- 

 venient mark by which to recognize the species and it is suggestive 

 of the specific name. In dried specimens this brown color is apt to 

 fade and disappear. The species might easily be taken to belong 

 to the genus O m p h a 1 i a, but is placed in Clitocybe because 

 of its fibrous stem and slightly decurrent lamellae. 



Pleurotus cornucopioides Pers. 



Decaying wood. Montezuma. October. The characteristic fea- 

 ture of this species is found in the decurrent lamellae. They are 

 prolonged in thin ridges or lines which run down the stem a half- 

 inch or more and give a fluted or striated appearance to its upper 

 part. The stem is eccentric or sometimes nearly central. 



Pleurotus similis n. sp. 



Pileus fleshy, flexible, spathulate, flabellate or suborbicular, con- 

 vex, glabrous, white or yellowish white, flesh white; lamellae thin, 

 subdistant, decurrent, distinct at the base, white; stem short, ascend- 

 ing, glabrous except at the villose base, solid, very eccentric or 

 lateral, white; spores subelliptic, .0002 to .0003 of an inch long, 

 .00012 to .00016 broad. 



Pileus 1 to 2 inches long, nearly as broad; stem 3 to 6 lines long, 

 2 to 3 thick. Single or cespitose. Prostrate trunks of ironwood, 

 Ostrya virginiana. West Shokan. August. 



The resemblance of this species to P. pantoieucus is so 

 close as to suggest the specific name given to it. It differs in its
