(in Ann. Micol. A. G. M. T. 1: 60. 2004), from which section takes its name. The includes eight European species (Beker & al., Hebeloma: 349. 2016). In course preparation a monograph North America, utilizing molecular as well morphological approaches, we determined examination holotype collection (cited above) that name was conspecific with well-established velutipes. This mushroom ectomycorrhizal; recorded mycorrhizal partners include: Abies, Arctostaphylos, Betula, Carpinus, Castanea, Corylus, Fagus, Helianthemum, Nothofagus, Picea, Pinus, Populus, Pseudotsuga, Salix and Tilia.
