Plectania rhytidia (Pezizales, Pezizomycotina) in Brazil: notes on its distribution and typification status

Plectania rhytidia is an uncommon discomycete now detected in Brazil. It is characterised by having a black ascomata, and transversally ribbed on one side ascospores measuring 19.6–27.4 (–29.4) × (6.9–) 7.8–12.3 μm. This species has been briefly referred to from Rio Grande do Sul without a detailed description and discussion. Studies on the genus Plectania in this country are scarce, and only P. chilensis, P.camplyspora, and P. milleri were cited. Previously, members of the genus have been mostly reported from temperate regions of the northern hemisphere, and in Australia and New Zealand. In this report, an interesting species of Plectania, found for the first time in the State of Paraiba, Brazil, is presented and comprehensively described. We also address the typification status of Peziza rhytidia, Urnula platensis, and U. torrendii.
