Peritliecia gregarious, sabgphaeroid, 300 a diam., their apices pro- 

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

 8-spored, 110-140x6 p. Sporidia uniseriate. Tmiseptate. nisoid. with 

 the endi subapieulate. slightly curved, nearly smooth. 15-24x5-6 t u, 

 hyaline. The white mold. Diplocladium minus, Bod.. is said to h* 

 its conidial stage.

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

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

 colored surface in which the subglobose peritliecia are thickly bedded, 

 with Only their slightly prominent reddish ostiola visible. Asci long 

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

 rough, hyaline, uniseptate. cuspidate-pointed at the ends. 30-3 s x6-8 u 

 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 (Tricothecium agaricinum, Bon.), then 

 deep rose-color or nearly blood-red. Peritliecia 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 fi, 

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

 ly carved, hyaline. 22-37x5-7 a sporidia nucleate or spuriously 1-3- 



te and often subinequilateral.
