THE LICHEN ORDER CALICIALES

Calicium, Chaenotheca, Cyphelium, Microcalicium, Sclerophora, Thelomma

This web page is dedicated to the tiny, but beautiful members of the lichen order Caliciales. The information is mostly based on the research done by Johan Mattsson and Jørn Middelborg in Norway during 1984-85 and published as Crustaceous lichenized species of the Caliciales in Norway, Sommerfeltia 5 (1987). The treatment excludes the non-lichenized family Mycocaliciaceae as well as macrolichens Sphaerophorus and Tholurna.
