The lichen genus Sarrameana

The genus Sarrameana (lichenised Ascomycotina: Sarrameanaceae) comprises four species: S. albidoplumbea, S. cyamidia comb. nov., S. septata and S. tasmanica . The genus is characterised by a distinctive ascus and excipulum structure, mostly straight, simple paraphyses and thin-walled, spiralled, simple or spuriously septate ascospores. Its relationships to other genera in the Lecanorales are discussed briefly. Species of Sarrameana are corticolous in cool, humid forests. Their distribution suggests a mainly austral cool temperate origin for the genus.
