 H. tubericola, (Selnv.) 



Sph&ria tubericola, Schw. Syn. N. Am. No. 1192. 

 Hypomyces tubericola, Cke. Syn. 335. 



Effused, thin, brown-black, margin scarcely determinate. Peri- 

 thecia at first subinimersed, finally erumpent ('-onmino proininulis"), 

 brown-black, rugose-tuberculate, minute, subconical, densely crowded, 

 at length collapsing. The interior of the perithecia is said to be en- 

 tirely similar to that of the preceding species, i. e. H. Lactifluorum, etc. 



On an old "White Tuber" infesting the outer bark. Found at 

 Pocono, Pa. (Schw.) 



H. boleticola, (Schw.) 



Sphcsria boleticola Schw. Syn N. Am. No. 1494. 

 Hypomyces boleticola, Cke, Syn. 336. 



Allied toff. <i ii r<i nt nix ( PIT*.), but distinguished by its paler color, 

 by the character of the subiculum (stroma) and shape of the perithecia. 

 Subiculum effused, interrupted, of loose texture, with irregular spaces 

 ("plagis irregularibus"), pale orange with the margin whitening out 

 Perithecia only partially immersed, conic-ovate, more or less scattered, 

 at first colored like the stroma, at length orange-red, rather soft, pap- 

 illate, easily separating from the stroma, leaving small cavities; con- 

 tents of perithecia very white, at length oozing out and remaining at- 

 tached to the ostiola. like a white villous pubescence. 



Found but seldom on very much decayed Polyporus v.i.1.rinnx.

 IV, p. 15. 



Of this species, but little appears to be known. It is stated by 

 Cooke, in Grevillea XII, p. 80, that the asci are cylindrical and the 

 sporiclia lanceolate, mucronate at each end, uniseptate, hyaline and 

 42-60 x 6-7 fjt. Found on some Agaric. 



Mycogone cervina Ditm., which is found on Helvella and on 

 various decaying Pezizas and Asterophora Pezizoe. Cda., on P '. hem- 

 ispherica, both of which are found here, are, with several similar molds 

 regarded as the conidial stage of different species of Hypomyces, of 

 which the ascigerous stage lias not yet been found.
