clavate or long-clavate; spores
ellipsoid to fusiform, 4- to 8-celled, 16 to 35 mic. long and 4 to 8
mic. wide.

Collected in Preble, Hocking, and Adams counties. Over mosses on rocks
or bases of trees; or rarely on rocks, soil, bark, or wood. Not
previously reported from Ohio, and not a common fungus in the State.

3. Bilimbia naegelii (Hepp) Zwackh. Flora. 45: 505. 1862.

_Biatora naegelii_ Hepp, Spor. Flecht. Eur. pl. 4. f. 1. 19. 1853.

Thallus of usually flattened granules, these commonly running together
to form a moderately thin, more or less roughened, often chinky, ash- or
green-gray, or darkening, limited or rarely wide-spread crust; apothecia
minute to middle-sized, 0.2 to 0.9 mm. in diameter, adnate or rarely
sessile, flesh-colored to dark brown, scattered or clustered, flat with
the thin exciple visible to strongly convex with the exciple covered;
hypothecium pale or tinged brown; hymenium pale throughout or tinged
brown above; paraphyses coherent, semi-distinct to indistinct; asci
clavate; spores fusiform-ellipsoid, 4- to 8-celled, 18 to 25 mic. long
and 3 to 4 mic. wide.

Collected in Highland County. On bark. Not previously reported from
Ohio, and doubtless rare in the State.

The usual width given for the spores is 4 to 6 mic., and our plant is
placed here provisionally.

4. Bilimbia melaena (Nyl.) Th. Fr. Lich. Scand. 383-385. 1871.

_Lecidea melaena_ Nyl. Bot. Not. 1853: 182. 1853.

Thallus of minute, olive-green to black-brown granules, these forming a
thin, granulose or scurfy, sometimes disappearing crust; apothecia
minute to small, 0.25 to 0.55 mm. in diameter, black-brown to black,
sessile, occurring singly or in clusters, strongly convex to subglobose,
the exciple soon covered; hypothecium pale brown to red-brown; hymenium
pale or tinged brown; paraphyses coherent, semi-distinct to indistinct;
asci clavate to inflated-clavate; spores oblong-ellipsoid or dactyloid,
2- to 4-celled, 12 to 22 mic. long and 4 to 6 mic. wide.

Collected in Lake County. On an old log in a wood. Not previously
reported in Ohio, and rare in the State.

Nylander called the apothecium pale within, but forms with red-brown
hypothecia are admitted by later writers.

5. Bilimbia microcarpa Th. Fr. Bot. Not. 1863: 8. 1863.

_Bilimbia obscurata microcarpa_ Th. Fr. Nov. Act. Soc. Sci. Ups. III. 3:
183. 1861.

Thallus of minute ash-gray or green-gray granules, these rarely forming
a thin or moderately thic
