Cryptothecia eungellae G. Thor

This species was originally described by Thor (1997) from Australia. It is characterized by its firmly attached, shiny thallus which reacts C+ red and the chemistry, i.e. gyrophoric and norstictic acids, both as major substances in our material. Cryptothecia eungellae is a new addition to the Thai lichen biota and a new record for the Northern Hemisphere.
