Cantharellus garnierii sp. nov., une nouvelle chanterelle des maquis miniers nickélifères de Nouvelle-Calédonie

Cantharellus garnierii sp. nov. is described from seven field collections from nickel mine maquis in New Caledonia. It was found in association with Acacia spirorbis, Casuarina collina and Nothofagus balancae among several other, quite common ectomycorrhizal fungi including genera such as Russula, Lactarius, Inocybe, Suillus, Boletus and Cantharellus… This taxon is characterised by the medium size of its yellow to yelloworange coloured carpophores, the mostly fasciculate growth on nickel-rich ultra basic soils, the medium sized spores, the relatively well-differentiated mediostratum and the clamped hyphae with distinctly thickened wall in the epicutis. No other known fungus has this combination of characters.
