ABSTRACT
Heterodermia squamulosa (Degel.) W.L. Culb. was found in the mountain of Gariwang, Gangwon province, in 2008. It is characterized by numerous squamules along the margin, decorticate and white lower surface, rhizines along the margin, black and densely squarrosely branched, usually forming a dense mat under the thallus. Apothecia margins densely squamulose, ascospores 12~15 × 25~30 µm. Atranorin and zeorin contained in thallus. This is the first record of this species in South Korea.

No MeSH data available.

Mentions: The specimens for this study were deposited in the Korean Lichen Research Institute (KoLRI) in Sunchon National University. The phenotypic characteristics were based on air-dried material. Morphological characteristics were observed using the dissecting microscope (Nikon SMZ 1500), and anatomy was examined using the compound microscope (Olympus BX 50). Lichen substances were detected by color reagents and thin-layer chromatography (Culberson, 1972; White and James, 1985).
