Remarks

public notes
  Mycorrhizal ends infrequently sinuous, yellowish to dirty yellow, often with a slight tinge of red; outer mantle layers in plan view with roundish-oval to roundish and lobed cells and sometimes hyphae still discernible; autofluorescence of mantle in section with UV-filter bluish, outermost layer yellowish, with blue-filter yellowish; mantle in sulfo-vanillin distinctly violet.
