Aspicilia exserta Hue (1910: 57)

Type (lectotype, designated here):— KOREA. Ryong-Kang, 01 September 1906, R. P. Faurie 414 ( LE L-7526a!, isolectotype PC 0090795).

According to Hue Aspicilia exserta differs by its thick whitish thallus with protruding apothecia which sometimes fuse together. The type specimen has furthermore convex areoles and bigger apothecia with thalline margin compared to the type of the previous species ( Fig. 1B ). However spore measurements do not differ substantially from those of A. adamanticola : (17.0) 18.3–[18.8]–19.2 (21.0) × (10.5) 11.4–[11.7]–11.9 (13.0) μm (n=10). The secondary metabolite is norstictic acid. Hue did not find conidiomata in this species, but we managed to reveal some conidia, which are 12 μm long. They are much shorter than those of A. adamanticola but agree in the size with conidia of A. cinerea ( Foucard 2001) . Chemical, morphological and anatomical characters of this species fall into variability of Aspicilia cinerea , with which we synonymize it here.
