| Popis: | Th e true truffl es, Tuber aestivum Vittad., T. borchii Vittad., T. magnatum Picco and T. melanosporum Vittad., are among the most studied fungal species; they also have a high economic value due to their special aromatic and nutritional properties that make them a much sought delicacy. Despite this, their identifi cation has been based on morphological and then molecular characters in the absence of reference type specimens. Although long of scientifi c, commercial and regulatory use, these four scientifi c names are at risk due to a lack of nomenclatural priority. To provide the scientifi c community with reference voucher samples and to initiate nomenclatural proposals for the recognition of their status as conserved names, three collections from sites mentioned by their authors (Picco and Vittadini) are proposed as epitypes for Tuber aestivum, T. borchii and T. melanosporum, and one as a neotype for T. magnatum. Th e type of each name is described morphologically and molecularly characterized with the sequences of three markers: ITS, ?-tubulin, elongation factor 1?. Th e taxonomy and nomenclature of each species are discussed. Th e conservation of the names Tuber aestivum against the previous homonymous Tuber aestivum (Wulfen) Spreng. and the competing name Tuber blotii Eudes-Desl., T. magnatum against Tuber griseum Borch ex Pers., and T. melanosporum against Tuber nigrum Bull. will be proposed. Th e name Tuber borchii has no previous synonyms and therefore it is legitimate and does not require conservation. |
