Aspicilia dimorphodes Hue (1910: 31)

Type (lectotype, designated here):— KOREA. Chemulpo, September 1906, R. P. Faurie 261 ( LE L-7522!, isolectotype BM 001107808 [digital photograph!]).

The type locality of this species is currently a built-up area of Incheon. Aspicilia dimorphodes was segregated by Hue on a basis of morphology of the thallus that consists of areolae of two types: the first are small and flattened and the second are enlarged and convex ( Fig. 1C ). The size of ascospores and conidia that had been provided by Hue (16–18 × 7–8 μm and 4–5 μm respectively) is smaller than we have got in our measurements (21.0) 22.5–[23.1]–23.6 (25.0) × (12.0) 12.9–[13.6]–14.3 (16.0) μm (n=10) and (8.0) 9.6–[9.8]–10.0 (11.0) μm (n=15) respectively). Abundant radiating black hyphae of Lichenothelia sp. on the thallus surface, which were mentioned by Hue, makes us sure that it is the same specimen that was studied by him. Enlarged areoles are not usual in Aspicilia intermutans but they might appear due to the parasite infection. In other aspects the thalli of Aspicilia dimorphodes are similar to those of A. intermutans .
