usually pruinose exciple, less frequently
becoming convex with the exciple rarely becoming covered; hypothecium
yellow to yellow-brown; hymenium pale yellow; paraphyses coherent,
semi-distinct to indistinct; asci long-clavate; spores about 7- to
14-celled, 40 to 70 mic. long and 3 to 5 mic. wide.

Collected in Butler and Adams counties. Also reported from Champaign and
Hamilton counties. On bark. This fungus appears to be rare in Ohio.

In one specimen, some of the disks are partly or wholly pruinose, but
the plant seemed nearer to this than to _Bacidia suffusa_ (Fr.) Fink.

Thallus thin and inconspicuous, or becoming thick and more prominent,
composed of rounded and often crowded or even heaped granules, these
frequently compacted into a continuous or scattered, verrucose and often
chinky, green-gray to olivaceous crust; apothecia small to large, 0.6 to
1.75 mm. in diameter, dark brown to black, adnate or sessile, flat or
slightly convex, the concolorous or lighter exciple frequently becoming
flexuous; hypothecium pale yellow to dark brown; hymenium pale yellow;
paraphyses coherent, distinct to semi-distinct: asci long-clavate;
spores about 7- to 15-celled, 40 to 70 mic. long and 2.5 to 3.5 mic.
wide.

Collected in Fairfield, Hocking, and Adams counties. On bark. Evidently
a rare fungus in Ohio.

5. Bacidia inundata (Fr.) Koerb. Syst. Lich. 187. 1855.

_Biatora inundata_ Fr. Vet. Akad. Handl. 1822: 270. 1822.

Thallus of minute granules, these usually compacted into a thin or
rarely thicker, granulate, chinky, or subareolate, ash- or green-gray or
darkening, commonly wide-spread, continuous or scattered crust;
apothecia minute to middle-sized, 0.2 to 0.75 mm. in diameter, pale
brown to finally black, adnate or rarely more or less immersed, usually
flat and bordered by the commonly lighter colored exciple, rarely
becoming convex, the exciple then finally covered; hypothecium pale to
brown; hymenium pale to pale brown; paraphyses coherent, semi-distinct
to indistinct; asci clavate to long-clavate, spores 4- to 8-celled, 15
to 40 mic. long and 1.5 to 2.6 mic. wide.

Collected in Butler, Preble, Highland, Adams, Warren, and Lake counties.
On various rocks in shaded or open moist places, and also about the
