Aspicilia microsporeta Hue (1910: 80)

Type (lectotype, designated here):— KOREA. Fusan, May 1906, R. P. Faurie 12 ( LE L-7531!, isolectotype BM 001107785 [digital photograph!]).

The specimens of Aspicilia geographica and A. microsporeta are very similar ( Fig. 1G, H ) but Hue does not discuss the reason why did he separate these species. The most reasonable version, which is also marked in the name, is smaller spores of the latter. Our measurements (10.0) 11.4–[11.6]–11.9 (13.2) × (5.0) 6.1–[6.3]–6.6 (7.9) (n=10) in A. geographica and (9.0) 10.1–[10.4]–10.6 (11.8) × (5.0) 5.5–[5.8]–6.0 (6.6) (n=10) in A. microsporeta do not support this difference. Both specimens contain atranorin and confluentic acid, have N+ pinkish epihymenium, J+ medulla and therefore belong to Lecanora oreinoides . The species is widely distributed in the Pacific region ( Rambold 1989) and has recently been found in Korea.
