New records of lichen genus thelotrema ach. (Thelotremoid graphidaceae) from South Korea.

This study illustrates the status of thelotremoid Graphidaceae in South Korea. The taxonomy and systematics of thelotremoid lichens in the country have recently advanced greatly. Following the earlier known taxa from the group, four new records of the genus Thelotrema are reported and described briefly. An artificial key for all known species under thelotremoid group of Graphidaceae from South Korea is also provided.

Notes on the Existence of Leucodecton desquamescens (Thelotremoid Graphidaceae) in South Korea.

This study describes a new record of a thelotremoid lichen (Leucodecton desquamescens) from South Korea. The taxon is characterized by thick, bulging thallus with many calcium oxalate crystal inclusions; an immersed, round to irregular ascomata with free exciple, ellipsoid to ± roundish submuriform, brown ascospores, and lack of secondary metabolites. A detailed taxonomic description and comments are presented for this taxon. The lichen genus Leucodecton is reported for the first time in South Korea.
