Tuber canirevelatum
Tuber canirevelatum is a recently described edible truffle species discovered in Tennessee, USA by Lois Martin and her truffle dog Monza. Tuber canirevelatum (revealed by dogs in Latin) was named in honor of all truffle dogs because they have been essential tools in the cultivation and collection of truffles.[1].
Description
Tuber canirevelatum ascomata[2], or fruiting bodies, are black to dark brown, ovoid, extremely warty, and 1-2 cm in diameter. The gleba, or spore containing tissue, of these truffles is light to dark gray and interspersed with sterile white veins[3]. Tuber canirevelatum asci are globose to ovoid, 84–108 × 69–89 µm, and contain 1-3 ascospores. The ascospores are a dark raw umber color, subglobose, spiny, with reticulate[4] alveolate[5] ornamentation. The ascospores appear spiny when observed under a light microscope because the alveolate meshes forms U-shaped valleys and are thickest where several meshes meet.
Aroma
The aroma of Tuber canirevelatum is described as pungent and similar to garlic or cilantro. Tuber canirevelatum truffles share some aromatic compounds found in well-known prized truffles. For instance, dimethyl sulfide was detected in Tuber canirevelatum ascomata and is also found in the black winter truffle[6] (T. melanosporum), summer truffle[7] (T. aestivum), and the white truffle[8] (T. magnatum).
Taxonomy and Phylogeny
Tuber canirevelatum is a member of the Macrosporum clade[9] which contains a North American species, Tuber canaliculatum[10], a European species, Tuber macrosporum[11], and several Asian species such as T. tomentosum[12] and T. calosporum[13]. The closest relative to Tuber canirevelatum is uncertain. Tuber canirevelatum and T. canaliculatum both have dark reticulated spores; however, T. canirevelatum does not have the distinct red exterior that T. canaliculatum has. Tuber canirevelatum and Tuber macrosporum both have garlicky aromas and associate with Oak trees but T. macrosporum spores do not appear to be spiny.
Habitat and distribution
Tuber canirevelatum is only known from a few collections in Oak Ridge, Tennessee, USA under Oak trees. It is assumed that Tuber canirevelatum is ectomycorrhizal as all Tuber species are[14]
