Dimerosporium echinatum, E. & E. 
On living leaves of Quercus chrysolepis, Jackson, Amador 
Co., Calif., Coll. Geo. Hansen, com. Marshall A. Howe. 
Epiphyllous, forming dense orbicular patches 3 to 4 mm. 
diam., made up of the densely crowded, bristly, black, ovate 
perithecia, 200 to 300 ~ diam., arising from a scanty, spar- 
ingly branched, septate, creeping mycelium, and thickly 
clothed with opaque, black bristles 70 to 110 u long, 5 to 7 m 
thick at the base. Asci clavate-cylindrical, short-stipitate, 
paraphysate, 8-spored, p. sp. 50 to 55x15 w. Sporidia mostly 
biseriate, ovate, uniseptate and slightly constricted, yellow, 
12 to 15x 6 to7 w. 7 
The perithecia are soon broadly perforated above, and the 
orbicular patches which they form often cover the entire 
surface of the leaf.

Epiphyllous. On the living leaves the perithecia are 
thickly scattered on large (1 cm.), white (reddish-brown 
below) orbicular spots with a narrow reddish-brown border, 
but on the dead leaves they are spread evenly over the whole 
surface of the leaf, not in spots. Perithecia globose, about 
+ diam., the apex strongly erumpent and covered by the 
mostly stellately cleft epidermis, above which the papilliform 
ostiolum scarcely projects. Asci oblong, abruptly contracted 
at base into a short nodular stipe, mostly narrower above. 
Paraphyses stout, septate below, attenuate above, but slightly 
enlarged at the tip. Sporidia biseriate, clavate-oblong, about 
4-septate, strorizly constricted at the second septum, but not 
at the others, hyaline, straight, obtuse, narrower below, 15 to 
27 x 6 to 7 u (mostly not over 20 long).
