Perithecia gregarious, subsphseroid, 300 /x diam., their apices pro- 

 jecting from the eifused, orange-colored subiculum. Asci cylindrical, 

 8-spored, 110-140x6 {i. Sporidia uniseriate, uniseptate, fusoid, with 

 the ends subapiculate, slightly curved, nearly smooth, 15-24x5-6 fi, 

 hyaline. The white mold, Diplocladium minus, Bon., is said to be 

 ite conidial stage.

In the affected specimens of Lactarius, the gills are entirely ob- 

 literated, so that the hymenium of the Agaric presents an even, orange- 

 colored surface in which the subglobose perithecia are thickly bedded, 

 with only their slightly prominent reddish ostiola visible. Asci long 

 and slender. Sporidia uniseriate, fusiform, straight or slightly cui-ved, 

 rough, hyaline, uniseptate, cuspidate-pointed at the ends, 30-38 x 6-8 //, 

 The general appearance is much the same as that of the preceding 

 ^ipecies, but the sporidia are larger, rough and warted and the felt-like 

 mycelium is wanting. In decay, the color changes to a purplish red. 



On Lactarius, especially L. piperatus. Carolina, (Ravenel),

Mycelium lax, effuse, consisting of loosely-woven threads, at first 

 white and beai-ing conidia (Tricothecium agaricinum, Bon.), then 

 deep rose-color or nearly blood-red. Perithecia deep rose-red, sub- 

 spherical or ovoid, of variable size, buried in the stroma, except the 

 projecting, rather obtuse, papilliform ostiola. Asci linear, 150x6-7 [i, 

 with eight uniseriate, narrowly lanceolate, apiculate, straight or slight- 

 ly curved, hyaline, 22-37x5-7 fj. sporidia nucleate or spuriously 1-3- 

 se})tati' and often suliinequilateral.
