Report of the Nomenclature Committee for Fungi: 22

Abstract

SummaryInformation on appointments to the Fungal Nomenclature Bureau is provided. Appointments to two Special‐purpose Committees are reported. The following four generic names are recommended for conservation: Bilimbia with a conserved type; Coccotrema against Lepolichen; Fuscidea against Maronea; and Leptogium (lichenized Ascomycota) with a conserved type. The following two generic names are not recommended for conservation: Marcelaria against Buscalionia; and Variolaria Pers. against Lepra and Variolaria Bull. The following seven species names are recommended for conservation: Lecidea parmeliarum (Abrothallus parmeliarum) against Endocarpon parasiticum; Lichen cervinus (Acarospora cervina) with a conserved type; L. ferrugineus (Blastenia ferruginea) with a conserved type; L. flavus Bellardi (Pleopsidium flavum) against L. flavus Schreb.; Megaspora verrucosa (Ach.) Arcadia & A. Nordin against M. verrucosa Hafellner & V. Wirth.; Umbilicaria spodochroa with a conserved type and with that spelling; and Usnea fulvoreagens with a conserved type. The following three species names are not recommended for conservation: Alectoria fuscescens (Bryoria fuscescens), nom. cons., against the additional names Usnea implexa, A. capillaris, A. cana, A. rubens, A. fuscidula, A. degenii, A. forissii, A. ostrobotniae, A. kuemmerleana, A. haynaldiae, A. achariana, A. lanestris, A. prostratosteola, and A. viridescens; Lichen fuscovirens (Collema fuscovirens) against L. pulcher; and Ochrolechia szatalaensis against Pertusaria poriniza. The following two species names are recommended for rejection under Art. 56: Lecidea cornea and Lichen conspurcatus. The following generic name is recommended for rejection under Art. 56: Huea (and the original proposal to conserve Huea with a conserved type is not recommended). It is recommended that the species name Variolaria torta not be rejected under Art. 56. The proposal to conserve Pertusariaceae against Variolariaceae is considered unnecessary because the latter name is illegitimate. The Nomenclature Committee for Fungi could not arrive at a recommendation on the proposal to conserve Lagerheimia (De Toni) Chodat against Lagerheima Sacc. and nor resolve requests for binding decisions on whether the pair Geisleria Nitschke and Geissleria Lange‐Bert. & Metzeltin and the pair Lagerheima Sacc. and Lagerheimia (De Toni) Chodat are sufficiently alike to be confused – but these three items have now been resolved by the General Committee.
