79. IIy^pomy^ces tegillum, B. & C. Grev. IV, p. 15. “On pine. 
Carolina. (Raven el). 
“ Reritliecia ovate, rufous-brown, scattered, a continuous white my¬ 
celium, like thin parchment.” 
80. IIypomyces flavescens, Schw. 
Perithecia gregarious, distinct, globose-ovate, papillate, whitish, 
covered with a villose coat that finally disappears, seated on a milk- 
white, broadly effused, pubescent subiculum ; asci cylindrical; sporidia 
narrowly-elliptical, hyaline (uniseptate) ? On hymenium of some lesu- 
pinate Polyporus. Pennsylvania (Schweinitz.) 
81. IIypomyces pannosus, Schw. 
Stroma effused, whitish, shaggy, thin, margin fimbriate-cottony ; 
perithecia semi-immersed, pale, with dark-colored, punctiform ostiola; 
asci cylindrical; sporidia (?) On rotten wood. Ex. Herb. Schw. The 
descriptions of this and the preceding species are taken from Grevillea 
XII, p. 80, and were, apparently, made from specimens in Herb. Berk 
eley. They are not in Schw. Synopsis X. Am. The H. pannosus here 
described is said to be a different thing from the Sphceria pannosa, Fr. 
In the next two species, the fructification is unknown. 
82. IIypomyces tubericola, Schw. Syn. X. Am., Xo. 1192. On 
an old “ White Tuber” infesting the outer bark. Found at Pocono, Pa. 
Effused, thin, brown-black, margin scarcely determinate; perithe¬ 
cia at first subimmersed, finally erumpent(“omnino prominulis”), brown- 
black, rugose tuberculate, minute, subconic, densely crowded, at length 
collapsing. The interior of the perithecia is said to be entirely similar 
to that of the preceding species, i. e., H. Lactifluonim, etc. Whether the 
“ White Tuber ” is an’old specimen of Pachyma, cocos is uncertain. 
83. IIypomyces boleticola, Schw. Syn. X. Am., Xo. 1494. 
Found but seldom on very much decayed Polyporus citrinus, at Bethle¬ 
hem, Pa. Allied to JT. aurantia, Fr., but distinguished by its paler 
color, by the character of the subiculum (stroma) and shape of the per¬ 
ithecia ; subiculum effused, interrupted, of loose texture, wuth irregular 
spaces (“ plagis irregularibus ”), pale orange with the margin whitening 
out; perithecia only partially immersed, conic-ovate, more or less scat¬ 
tered at first, colored like the stroma, at length orange-red, rather soft, 
papillate, easily separating from the stroma, leaving small cavities, con¬ 
tents of the perithecia very white, at length oozing out and remaining 
attached to the ostiola like a white villous pubescence. 
Mycogone cekyina, Ditm, which is found on Jlelvelhi and on 
various decaying Pezims and Asterophora Pezizce, Oda., on P. kemispherica, 
both of which are found here, are, with several similar molds, regarded 
as the conidial stage of different species of IIypomyces, of which the 
ascigerous stage has not been found. 
Gen. VI, Polystigma, Persoon.— (Moug. et Xest, Xo. 270). Stroma 
subcarnose, effused, colored (ochraceous, red or yellow), phyllogenous ; 
perithecia immersed ; asci 8-spored ; sporidia ovoid, continuous, hyaline.
