Gen. X. Lasionectria, Sacc.—Perithecia hairy. 
145. Lasionectria poliosa, E. & E. Parasitic on Diatrype platys- 
toma , Schw., Florida, January, 1886. VV. W. Calkins, No. 138. Journ. 
Mycol. II, p. 39. 
Perithecia scattered, membranaceous, orange red, ovate-globose, one 
sixth millim. in diam., sparsely clothed, except the papilliform ostiolum, 
with straight, spreading, hyaline, septate, glandular hairs, about equal in 
length to half the diameter of the perithecia ; asci sessile, oblong-cylin¬ 
drical, about 75 x 12 !>-; sporidia biseriate, oblong or subfusiform-oblong 
and subinequilateral, hyaline, uniseptate and slightly constricted at the 
septum, containing several nuclei irregularly placed, 18—22x 7—8 ends 
rounded or subacute. The hairs which clothe the perithecia are at first 
about seven ! l thick, with the ends obtuse and a little swollen, but at 
length they become elongated and attenuated above. This must be nearly 
allied to N. teplirothele , Berk., but in the description of that species the 
perithecia are not described as hairy. 
146. Lasionectria lasioderma (Ell.) Am. Nat., February, 1886, 
p. 194. Parasitic on old Valsa lutescens, Ell., on dead limbs of Quercus 
coccineci , lying on the ground, Newfield, N. J., June, 1882. 
Perithecia mostly single, subamorphous, obtuse-conic, broadly per¬ 
forated above, about one fourth millim. high, shaggy with short, 
septate, obtuse, imperfectly-developed hairs, dull red when dry, pale 
orange when moist; asci cylindrical, 75—80 x 7—8 !■>■; sporidia uniseriate, 
elliptical, hyaline, uniseptate, scarcely constricted, 11—12 x 4—5 y.
