THE ASCOMYCETES OF OHIO IV 
347 
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 Cham¬ 
paign 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 sujfusa (Fr.) Fink. 
4. Bacidia schweinitzii (Tuck.) Fink Cont. Nat. Herb. 14: 89.1910. 
Biatora schweinitzii Tuck, in Dari. FI. Cestr. ed. 3. 447. 1853. 
Thallus thin and inconspicuous, or becoming thick and more prom¬ 
inent, 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 Fairfleld, Hocking, and Adams counties. On bark. Evi¬ 
dently 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 Anally black, adnate 
or rarely more or less immersed, usually flat and bordered by the commonly 
lighter colored exciple, rarely becoming convex, the exciple then Anally 
covered; hypothecium pale to brown; hymenium pale to pale brown; para¬ 
physes 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 coun¬ 
ties. On various rocks in shaded or open moist places, and also about the 
moist shaded bases of rocks in dry fields. Also reported from Cuyahoga 
county and doubtless common in all parts of the State. 
6. Bacidia incompta (Borr.) Anzi, Cat. Lich. Sondr. 70. 1860. 
Lecidea incompta Borr. in Sowerby, Engl. Bot. Suppl. 2: pi. 2699. 1834. 
Thallus of very minute granules, these forming a continuous or more 
or less broken, wide-spread, sometimes thick and rugose or rarely even 
subareolate, or again thin, smooth, more or less mealy, light or darker 
green-gray, rarely disappearing crust; apothecia minute to middle-sized, 
0.3 to 0.75 mm. in diameter, dark brown to black, adnate to sub-sessile.
