Malmidea badimioides (Cáceres & Lücking) Cáceres & Kalb

This species was recently described from the Mata Atlântica of northeastern Brazil (Cáceres 2007). It is readily recognized by apothecia with a granifera - type exciple and the orange-brown to brown-red colour of the discs. Althoug the hypothecium in the specimen below is more intensely coloured than in the type, cochromatography of both in solvents A, B’ and C revealed an identical array of at least 6 unknown substances, but no atranorin could be detected by TLC (Elix & Ernst-Russell 1993). Malmidea badimioides is a new addition to the Mexican lichen biota and is reported from the Northern Hemisphere for the first time.
