Agaricacese 



Armillaria. A. appendicula'ta Pk. bearing an appendicula or small appendage. 

 Pileus broadly convex, glabrous, whitish, often tinged with rust color 

 or brownish rust color on the disk. Flesh white or whitish. Gills 

 close, rounded behind, whitish. Stem equal or slightly tapering up- 

 ward, solid, bulbous, whitish, the veil either membranous or webby, 

 white, commonly adhering in fragments to the margin of the pileus. 

 Spores subelliptical, 8x5/1*,. 



Pileus 2-4 in. broad. Stem 1.5-3.5 in. long; 5-10 lines thick. 



Auburn, Ala. October. C. F. Baker. 



The general appearance of this species is suggestive of Tricholoma 

 album, but the presence of a veil separates it from that fungus and places 

 it in the genus Armillaria. The veil, however, is often slightly lacer- 

 ated or webby and adherent to the margin of the pileus. Peck, Bull. 

 Torrey Bot. Club, Vol. 24. 



Mt. Gretna, Pa., Angora, Pa. On decaying roots in ground. August 

 to November. Found plentifully in resorts of other Armillaria. Edi- 

 bility the same. Mcllvaine. 



A. pondero'sa Pk. ponderosus, weighty, ponderous. Pileus thick, 

 compact, convex or subcampanulate, smooth, white or yellowish, the 

 naked margin strongly involute beneath the slightly viscid, persistent 

 veil. Gills crowded, narrow, slightly emarginate, white inclining to 

 cream color. Stem stout, subequal, firm, solid, coated by the veil, 

 colored like the pileus, white and furfuraceous above the ring. Flesh 

 white. Spores nearly globose, 4;* in diameter. 



Plant 4-6 in. high. Pileus 4-6 in. broad. Stem about I in. thick, 



Ground in woods. Copake, Columbia county. October. 



The veil for a long time conceals the gills, and finally becomes lacera- 

 ted and adheres in shreds or fragments to the stem and margin of the 

 pileus. Peck, 26th Rep. N. Y. State Bot. 



New England, Frost; New York, Peck, Repts. 26, 29, 41. West Vir- 

 ginia and Pennsylvania. Ground in woods. September to November. 

 Mcllvaine. 



Professor Peck says in 26th Report: "This species has not been 

 found since its discovery in 1872." 



Where the Armillaria mellea frequents I have often found A. pon- 

 derosa. It was plentiful at Mt. Gretna, Pa., in September, 1898.
