Echinodiscus lesdainii gen. et comb. nov., a new name for Phacopsis lesdainii Vouaux (lichenicolous Ascomycetes, Leotiales)

The new genus Echinodiscus Etayo & Diederich is introduced to accommodate the lichenicolous ascomycete Phacopsis lesdainii Vouaux, and the new combination E. lesdainii (Vouaux) Etayo & Diederich is proposed. As the holotype has been destroyed, a neotype is selected for this fungus.
