Abstract english

The new species Eilifdahlia schwarzii F. Schumm & S. Y. Kondr. is described. It differs from the more common southern Australian E. dahlii (Elix, S. Y. Kondr. & Kärnefelt) S. Y. Kondr., Kärnefelt, Elix, A. Thell, J. Kim, A. S. Kondr. & J.-S. Hur in having a poorly developed whitish thallus, bright yellow to bright yellow-orange apothecia, with a persistent glossy margin, a proper exciple with scleroplectenchymatous tissue, longer ascospores, and wider ascospore septa. The new species is known from scattered localities in Western Australia. The new combination E. sergeyana (Kantvilas) S. Y. Kondr., Elix, Kärnefelt & A. Thell is made, and a key to the species of Eilifdahlia is presented.
