2. Peckiella camphorati (Peck) 



Hypomyces camphorati Peck, Bull. N. Y. State Mus. 105 : 23. 



Stroma consisting of a thin effused subiculum overspreading 

 the hymenium of the host and obliterating the gills, forming an 

 even layer, bright lemon-yellow sometimes slightly fading; peri- 

 thecia numerous, small, immersed in the subiculum or v^ith the 

 ostiola slightly protruding, darker than the subiculum, pale 

 brownish; asci cylindrical, 8-spored ; spores i-seriate, fusiform 

 with a short apiculus at each end, occasionally blunt at both 

 ends, smooth or very minutely rough, 15-20X4 mic, simple 

 oozing out and forming a white powder over the surface of the 

 stroma {pi. 21, f. 6). 



On the hymenium of Lactaria camphorata. 



Type locality : New York. 



Distribution : New York. 



Specimens examined: New York, Peck (type), Murrill 26JS. 



The spores of this species are similar in size and general ap- 

 pearance to those of Peckiella lateritia but the species is easily 

 distinguished by its bright lemon-yellow stroma.

Stroma effused, more or less cottony, forming an even layer 

 on the hymenium and more rarely on the stem of the host, en- 

 tirely obliterating the gills, at first white becoming pale yellow or 

 yellowish-brown; perithecia thickly scattered, immersed or with 

 the necks of the ostiola more or less prominent, darker than the 

 subiculum, yellowish or brownish, ovate; asci cylindrical, 8- 

 spored, of variable length often attaining a length of 200 mic. ; 

 spores fusiform, usually with a distinct apiculus at each end, 

 unequal sided, at first smooth, becoming delicately verrucose.
