BERKELEY’S TYPES OF FUNGI. 107 
PaTELLARIA styGta, Berk. § M. A. Curt. in Grevillea, vol. iv. 
(1875) p. 2. (Pl. 4. figs. 15-17.) 
Gregarious, or sometimes crowded, orbicular, plane, marginate, 
attached by a central point, margin free, glabrous, black, about 
1 mm. across; hypothecium dark-coloured, parenchymatous, 
running out at the surface and margin into large hexagonal cells, 
15-20 x 8-12 p, arranged in rows, external cells almost globose, 
dark; asci cylindric-clavate, apex slightly narrowed and thick- 
walled, apex alone blue with iodine, 50 x 6-7 4; spores 8, irregu- 
larly 2-seriate, cylindrical, ends very slightly narrowed, 1-septate, 
brown, often very slightly curved, 15-16 x44; paraphyses very 
slender, septate, tips thickened, brown, agglutinated together. 
Patella stygia, Sace. Syll. viii. n. 3215. 
On wood. New Jersey ; Lower Carolina; Boston (Sprague, 
n. 6234). 
This species will stand as Karscura sryata, distinguished by 
the narrow cylindrical spores and the large cortical cells of the 
ascophore. 
PareLtarta Broxami, Berk. in herb.; Phillips, Brit. Disc. 
p- 351. (Pl. 4. figs. 18-14.) 
Gregarious, sessile, fixed by a central point, applanate, 
glabrous, at first with a slightly upraised margin, then plane or 
slightly convex, black, about 2 mm. across ; excipulum minutely 
parenchymatous, blackish-olive, cells becoming arranged in rows 
and almost quadrate towards the exterior and margin; asci 
cylindric-clavate, not much narrowed at the base, apex slightly 
narrowed and thick-walled, everywhere deep, clear blue with 
iodine, 50-60 x 7-8 p3; spores 8, irregularly 2-seriate, elliptical 
or fusoid, 1-septate, brown, 10-15 x 5-7»; paraphyses very 
slender, septate, tips thickened, brown, more or less agglutinated 
together. 
Karschia Bloxami, Sace. Syll. viii. n. 3208. 
On rotten wood. Engiand (Bloaam). 
Allied to Karschia lignyota, but readily distinguished by 
having the two cells of the spore of equal size. 
Parertarta ara, Berk. in herb. (Pl. 4. figs. 11, 12.) . 
Superficial, attached by a central point, expanded and slightly 
Concave; substance thin, glabrous, blackish brown (when dry), 
15 mm. across, irregularly contracted when dry ; hypothecium
