KORF, Richard P.. On the genus Solenopezia (Fungi, Lachnaceae): Peziza solenia and ICBN Art. 58 — a sleeping dog bites back. Bol. Soc. Argent. Bot. [online]. 2007, vol.42, n.1-2, pp.29-32. ISSN 1851-2372.

De Candolle described Peziza solenia in 1805, erroneously believing his fungus to be an Ascomycete, but it is a Basidiomycete . Peziza solenia DC. was later treated as a synonym of Solenia fasciculata Pers. It has been sleeping in that synonymy ever since. In 1873 Peck described a true Discomycete, Peziza solenia Peck. The name is a later homonym, validly published but illegitimate. Under Article 58 of the current International Code of Botanical Nomenclature (ICBN) epithets of such illegitimate names are available for transfer to another genus, but the new name takes new authorship and dates from the transfer. Peziza solenia Peck has been transferred into four other genera, all belonging to the Hyaloscyphaceae or Lachnaceae. The first author to transfer Peck's species was Saccardo, who placed it in a new genus, Solenopezia Sacc. Several authors proposed S. solenia as the «type species» of the genus, but of these the only acceptable lectotypification was that by Raitviir in 1973. The authorities for all four combinations need to be changed to agree with Article 58 of the ICBN with Peck's name and date deleted and Saccardo's name and date substituted. An alternative solution using the ex formulation is advocated here.
