The new species Astrothelium inspersaeneum and Diorygma longisporum are described from northeastern Brazil. These species were all found only in the Caatinga reserve Vale do Catimbau in Pernambuco. The Astrothelium is, according to current key characters, referable to the genus Trypethelium, but it is clearly a member of the Astrothelium conicum-group and thus described in that genus.
