Concluded that this is a Gomphidius after looking at the protonym (http://biodiversitylibrary.org/... and http://www.librifungorum.org/...) which states it has white flesh with a yellow base to the stipe, and noting that it is discussed as Gomphidius flavidus in the paper Miller, Aime, Camacho & Peinter “Two new species of Gomphidius from the Western United States and Eastern Siberia” Mycologia November/December 2002 vol. 94 no. 6 1044-1050 (http://www.mycologia.org/content/94/6/1044.full) and it clearly lands inside the genus in the phylogenetic tree.
Furthermore in Miller Jr., O.K. (2003). The Gomphidiaceae revisited: a worldwide perspective. Mycologia 95(1): 176-183 he states:
“It is interesting to note that Gomphidius flavipes was placed in Chroogomphus by Miller in 1964 since it has scattered amyloid tramal cells. However, unlike spe- cies of Chroogomphus, it has the yellow stipe base and white pileus trama of a typical species in Gomphidius. Our sequence data leave little doubt that this transi- tional species between the two genera really belongs in Gomphidius, where we have now placed it (Miller and Aime 2001).”
