(≡ P. viridifusca Delile ex De Seynes), Peziza elaeocarpa comb. nov. (≡ P. olivacea Quél.), Peziza pauli nom. nov. (≡ P. martinii Donadini), and Peziza queletii nom. nov. (≡ P. ampelina Quél.). Key words — Pezizaceae, Pezizales, nomina nova Some species of European Peziza Dill. ex Fr. : Fr. have no legitimate names in Peziza and are known currently by illegitimate names (later homonyms; McNeill et al. 2012, Article 53.1). This work resolves these nomenclatural irregularities. Peziza delilei Medardi, Lantieri & Cacialli, nom. nov. MycoBank MB808495 ≡ Peziza viridifusca Delile ex De Seynes, in De Seynes, Veg. Inf. 3: 83. 1886, nom. illegit., non Peziza viridifusca Fuckel 1870. ≡ Humaria viridifusca Sacc., Syll. Fung. 8: 149. 1889. ≡ Galactinia viridifusca (Sacc.) Boud., Hist. Class. Discom. Eur.: 48. 1907. Etymology: after Alire Raffenau Delile, who discovered the species. Peziza elaeocarpa (Sacc.) Medardi, Lantieri & Cacialli, comb. nov. MycoBank MB808494 ≡ Peziza olivacea Quél., Bull. Soc. Bot. Fr. 25(4): 291. 1879 [“1878”], nom. illegit., non Peziza olivacea Batsch 1783. ≡ Humaria elaeocarpa Sacc., Syll. Fung. 8: 148. 1889. 204 ... Medardi, Lantieri, & Cacialli Peziza pauli Medardi, Lantieri & Cacialli, nom. nov. MycoBank MB808493 ≡ Peziza martinii Donadini, Bull. Soc. Linn. Provence 35: 171. 1985 [“1984”], as “martini”, nom. illegit., non Peziza martinii Pers. : Fr. 1822. Etymology: from Paulus, the Latinized baptismal name of Paul Martin, to whom the species was originally dedicated. Peziza queletii Medardi, Lantieri & Cacialli, nom. nov. MycoBank MB808492 ≡ Peziza ampelina Quél., Grevillea 8(47): 116. 1880, nom. illegit., non Peziza ampelina Pass. 1874. ≡ Plicaria ampelina Rehm, Rabenh. Krypt.-Fl., Ed. 2, 1(3): 1003. 1894. ≡ Galactinia ampelina (Rehm) Boud., Hist. Class. Discom. Eur.: 47. 1907. Etymology: after Lucien Quélet, who discovered the species. Comments: We do not accept the synonymy of P. ampelina Quél. with P. arenaria Osbeck 1762 (as reported by Species Fungorum, http://www.speciesfungorum. org/GSD/GSDspecies.asp?RecordID=148680); the few characters of Osbeck’s original diagnosis of P. arenaria delineate a brown, cup-shaped, sabulicolous species with a split margin, not a typical violaceous, saucer-shaped fungus, which is P. ampelina of Quélet.
