340 OHIO BIOLOGICAL SURVEY 
Collected in Preble, Butler, Warren, Adams, Fairfield, and Lake coun¬ 
ties. On dead wood. Widely distributed in Ohio. 
8. Lecidea sylvicola Koerb. Syst. Lich. 254. 1855. 
Thallus of minute, irregular, somewhat flattened or more rarely hemis¬ 
pherical, green-gray, olive-brown, or darker granules, these forming a thin, 
continuous, or rarely scattered, subleprose, verrucose, or even subareolate, 
wide-spread crust; apothecia minute to small, 0.2 to 0.5 mm. in diameter, 
adnate or rarely more or less immersed, dark brown to black, flat to con¬ 
vex, the black exciple soon becoming covered; hypothecium brown to 
black-brown; hymenium pale or tinged brown; paraphyses coherent, semi- 
distinct to indistinct; asci clavate; spores ellipsoid, 5 to 9 mic. long and 2.5 
to 4 mic. wide. 
Collected in Lake, Ross, Preble, Hocking, and Butler counties. On 
various rocks. Not previously reported from Ohio, and apparently new to 
America under this name. Widely distributed in Ohio. 
For possible relationship to Lecidea myriocarpoides Nyl. See “The 
Lichens of Minnesota” (Cont. Nat. Herb. 14: 74.1910). 
9. Lecidea flexuosa (Fr.) Nyl. Act. Soc. Linn. Bord. 21. 356.1856. 
Biatora flexuosa Fr. Vet. Akad. Handl. 1822: 267. 1822. 
Thallus of small or minute, flattened or rugose, scattered or clustered, 
ash-grey to green-gray granules, these bursting into sorediate heaps, or 
forming a moderately thick, areolate crust; apothecia minute to small, 0.2 
to 0.4 mm. in diameter, adnate, black, and flat, the thin, livid or darker, 
persistent exciple becoming flexuous; hypothecium pale or darker brown; 
hymenium tinged brown; paraphyses coherent, semi-distinct to indistinct; 
asci cylindrico-clavate; spores oblong-ellipsoid, 5 to 10 mic. long and 3 to 
5 mic. wide. 
Collected in Preble, Adams, Ross, and Butler counties. On dead wood. 
Not previously reported from Ohio, and rare, though probably distributed 
widely in the State. 
The spores are slightly below normal size in our specimens. 
10. Lecidea enteroleuca Ach. Lich. Univ. 177. 1810. 
Thallus thin or becoming moderately thick, smooth or more often 
granulate, chinky or areolate, the granules or verrucae rarely becoming 
heaped in the thicker forms, ash-to green-gray, occurring in rounded areas, 
or irregularly and often widely spread over the substratum; apothecia 
minute to middle-sized, 0.35 to 1.2 mm. in diameter, adnate, black, flat to 
more commonly convex, the frequently flexuous exciple often becoming 
covered; hypothecium pale to dark brown; hymenium pale below, but 
usually more or less colored above; paraphyses distinct, but often more or 
less coherent; asci clavate; spores ovoid-ellipsoid, 8 to 17 mic. long and 
5 to 9 mic. wide (Fig. 3).
