Agaricacese 



pieurotus. The species is not noticeably viscid after its youth. The viscidity 

 can be detected in old specimens by moistening the pileus. Its flavor 

 is not marked, nor is its texture as pleasing as most others of its genus, 

 but being a late species it satisfies the longing of the mycophagist for 

 his accustomed food. 



P. pulmona'rius Fr. pulmo, lung, from texture. PileilS 2-3 in. 



broad, ash-colored, continuous with the stem, fleshy, soft, but tough, 

 flaccid, obovate or kidney-shaped, plane or reflexo-conchate at the mar- 

 gin, even, smooth. Flesh thin, soft, white. Stem very short, solid, 

 exactly lateral, horizontal or ascending, round, villous, expanded into 

 the pileus. Gills decurrent but ending determinate ly, moderately broad, 

 distinct, not branched or anastomosing at the base, livid or ash-color. 



The primary form is solitary. The pileus is ashy-tan when dried. It 

 differs from A. salignus alike in the definitely lateral stem and in the 

 thin flaccid pileus. Fries. 



Not previously reported. 



Found by Miss Madeleine Le Moyne, Washington, Pa., September, 

 1898, and sent to writer. Gills 3 lines broad, not narrow in proportion 

 to flesh. 



Taste and smell similar to P. ostreatus. Cooked it is tender, and 

 more succulent than P. ostreatus. 



III. RESUPINA'TI. 



P. mastruca'tllS Fr. mastrnca, a sheepskin. PileilS up to 2 in. 



long and I in. broad, sessile, at first resupinate then expanded and 

 horizontal, often lobed, upper stratum of pileus gelatinous, brown, 

 bristling with squarrose or erect squamules. Flesh thickish. Gills 

 radiating from the point of attachment, broad, rather distant, grayish- 

 white. 



On old trunks. Imbricated. Readily distinguished by the brown, 

 squarrosely scaly pileus. Massee. 



Spores oblong, oblique, 8x5/u. Morgan. 



In June, 1886, the writer found this species in oak woods near Phila- 

 delphia. It grew on fallen trunks and on decaying spots of living 

 timber. 



It is edible, and of good flavor, but is rough in the mouth. If found 

 in quantity, the extract of it would make a delicate soup.
