110 MR. G@. MASSEE—REDESCRIPTIONS OF 
at first closed, then gradually expanding until saucer-shaped, 
finally plane, or even very slightly convex, usually with the 
extreme margin upturned, up to 2 mm. across; dise blackish, 
externally paler, and with the margin irregularly raised when 
dry; substance entirely composed of rather stout, interwoven 
hyphe, which become thickened, brown, and arranged in a 
parallel series at the margin; asci clavate, apex rounded, pore 
blue with iodine, wall rather thick, about 110 x 11-12; spores 
8, irregularly 2-seriate towards the apex of the ascus, obliquely 
1-seriate below, hyaline, smooth, elliptic-fusiform, ends acute, 
3-septate, 19-22 x 6-7 1; paraphyses very numerous, filiform, 
more or less agglutinated together at the tips, which are not at 
all thickened.

On bark of Acer. New England (Sprague, n. 5831). 
This species proves, on examination, to be synonymous with 
Tympanis conspersa, Fries, as defined in Brit. Fung.-F). iv. 128, 
from specimens sent by Fries to Berkeley, which also agree 
with Fries’ Scler. Suec. nn. 12 &171. The drawing accom- 
panying the specimen called Tympanis rhabdospora in Berkeley’s 
herbarium shows that the numerous minute spores in the ascus 
were mistaken for granular protoplasm, and that the slender 
paraphyses were, in turn, mistaken for filiform spores.

(1875) p.3; Sace. Syll. viii. n. 2403. (PI. 4. figs. 37, 38.) 
Densely crowded in small groups of 6-12 individuals, slightly 
concave and irregular from mutual pressure when moist, laterally 
compressed and completely concealing the dise when dry, 
brownish-black, glabrous, sessile, 1-2 mm. across ; substance 
formed of rather stout, interwoven hyphe which are deep brown 
in colour at the cortex; asci clavate, apex rounded, and not at 
all blue with iodine, wall thick especially upwards, 70-80 x 12 5
