 Cercospora argythamniae Dearness & House sp. nov. 



Spots beginning as a yellowish green discoloration of the naturally 

 purplish leaf, not determinate ; the fruiting part with a definite yel- 

 lowish or brownish border surrounded by a greenish rim, opaque 

 when held up to the light, 2-4 mm in diameter and thickly dotted 

 with the dark tubercular bases of the tufts of conidia ; conidia aris- 

 ing from short or obsolete hyphae, pale brown when viewed with 

 reflected light; amphigenous, obclavate, 15-40 \x by 2 [x above to 3 or

On Argythamnia mercurialina Muell. Caddo, In- 

 dian Territory (Oklahoma), June 22, 1891. Charles S. Sheldon. 



Related to Cercospora crotonifoliae Cooke, which is 

 epiphyllous and has cylindrical spores. 



Gymnopilus subviridis Murrill, sp. nov. 



Pileus convex to nearly plane, circular, 8-10 cm broad ; surface 

 dry, dull green with a bluish green bloom, becoming glabrous with 

 age ; margin very involute, undulate, not at all appendiculate ; con- 

 text greenish yellow with an agreeable odor; lamellae deeply emar- 

 ginate, broad, inserted, distant, brownish green, uneven on the 

 edges ; spores broadly ovoid to sul:)globose, ferruginous, asperulate, 

 about 5 by 3.5-4 m ; stipe long, slender, flexuous, largest at the mid- 

 dle, concolorous, staining brownish, fleshy-fibrous, greenish within, 

 reaching 10-15 cm in length and i cm in thickness. 



Type collected on a decayed fir stump at Olympia, Wash., No- 

 vember 27, 1914, by Miss M. McKenny (Herb. N. Y. State Mu- 

 seum). This is an interesting addition to the large number of spe- 

 cies of this genus from the Pacific coast. It may readily be recog- 

 nized by its green color. Two other species, G. s u b f 1 a v i d u s 

 Murrill and G. v i r i d a n s Murrill, become green spotted when 

 handled, but they are entirely dififerent from Miss McKenny's plant. 

 For the benefit of those using Saccardo's nomenclature, this species 

 is recombined as F 1 a m m u 1 a subviridis Murrill.
