rose, green-gray to dark-olive
crust; apothecia minute to small, 0.2 to 0.5 mm. in diameter, adnate,
commonly carneous or darkening, more or less convex and usually becoming
convex with the exciple finally covered; hypothecium pale or pale brown;
hymenium pale below and commonly darker above; paraphyses coherent,
semi-distinct to indistinct; asci clavate; spores oblong-ellipsoid, 8 to
12 mic. long and 3.5 to 5 mic. wide.

Collected on Little Mountain in Lake County. On a rotten log. Not
previously reported from Ohio, and evidently rare in the State.

Simple spores were seen in the specimens collected, but they were
supposed to be immature.

3. Biatorina lentibularis (Ach.) Koerb. Syst. Lich. 191. 1855.

_Lecidea lentibularis_ Ach. Syn. Meth. Lich. 28. 1814.

Thallus a thin, smooth or subtartareous, rarely rimose-areolate,
ash-white to brown-gray, wide-spread and continuous or finally
disappearing crust; apothecia minute to small, 0.2 to 0.5 mm. in
diameter, adnate, black, from flat becoming convex and often irregular,
the inconspicuous exciple then becoming covered; hypothecium pale to
darker brown; hymenium pale or tinged brown; paraphyses distinct to
coherent-indistinct; asci clavate; spores oblong-ellipsoid, 8 to 11 mic.
long and 2.7 to 4 mic. wide.

A single collection was made in Highland County. On exposed calcareous
rocks. Not previously reported from Ohio, and doubtless rare in the
State.

An occasional 4-celled spore was seen, a transitional character
previously noted by Th. M. Fries. The plant is closely related to the
next below, from which it may not be distinct.

4. Biatorina chalybeia (Borr.) Mudd, Man. Brit. Lich. 180. 1861.

_Lecidea chalybeia_ Borr. in Sowerby, Eng. Bot. Suppl. 1: pl. 2687. f.
2. 1831.

Thallus a thin, smooth or roughened, ash-gray and darkening crust,
forming a continuous layer, becoming inconspicuous and rarely
disappearing; apothecia minute to small, 0.3 to 0.5 mm. in diameter,
adnate to sessile, concave to slightly convex, black, the exciple
concolorous, prominent, and rarely becoming covered; hypothecium dark
brown; hymenium pale below and pale brown above; paraphyses wide and
strong, distinct to coherent-indistinct; asci clavate; spores
oblong-ellipsoid, 8 to 12 mic. long and 3.5 to 4.75 mic. wide (Fig. 4).

Collected in Butler County. On calcareous rocks. Not previously reported
from Ohio, and probably rare in the State.

The spores are somewhat larger than in
