Perithecia gregarious, subspfraeroid, 300 tt diain., their apices pro- 

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

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

 the end? subapieulate, slightly curved, nearly smooth, 15-24x5-6 p, 

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

 its 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 subgiobose perithecia are thickly bedded, 

 with only their slightly prominent reddish ostiola visible. Asci long 

 and slender. Sporidia uniseriate, fusiform, straight or slightly curved, 

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

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

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

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

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

 white and bearing conidia (Tricotkecium agaricinum, Bon.), then 

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

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

 projecting, rather obtuse, papilliforni ostiola. Asci linear, 150x6-7 jut, 

 \\-ith eight uniseriate, narrowly lanceolate, apiculate, straight or slight- 

 ly eurved, hyaline. 22-37x5-7 // sporidia nucleate or spuriously 1-3- 

 -cptate and often subinequilateral.
