aff.
ID Remarks:
As in DJM 1981 morphology and basidiospores agree with descriptions of this species, e.g., H. Knudsen and J. Vesterholt, eds., Funga Nordica (2012) and Miller and Miller (2006), North American Mushrooms, but colors of the dried fruiting bodies in this collection are much darker than reported for C. alboviolaceus, and the white universal veil is much thicker and more persistent than reported. Sequence needed to confirm identification.
