Kuyper (1995) places Clitocybe robusta in synonymy with Clitocybe nebularis var. alba, as does Bigelow (1982); however, Bigelow elevates Clitocybe robusta to species status. My humble opinion, for what it's worth, is that Bigelow and Kuyper have different mushrooms in mind. Kuyper treats gray and white varieties of Clitocybe nebularis, which he says are often found growing together in the Netherlands, while Bigelow treats two very distinct mushrooms from western North America.
