Lichenothelia renobalesiana sp. nov. (Lichenotheliaceae), for a lichenicolous ascomycete confused with Polycoccum opulentum (Dacampiaceae)

subject

description

Abstract:The name Polycoccum opulentum proves to have been wrongly applied to a lichenicolous fungus belonging to the genus Lichenothelia, and which differs from the type material of P. opulentum in having non-ostiolate broadly stipitate ascomata and narrow ascospores with a conspicuous gelatinous sheath. The Lichenothelia represents an hitherto undescribed species, named here as L. renobalesiana, sp. nov. which is associated with verrucarialean lichens on hard limestones in temperate regions. The true P. opulentum is known only from the original collection on Polyblastia hyperborea from Sweden.
