Recognized by sight: Can look macroscopically identical to C. vinicolor and C. rutilus (which doesn’t appear to occur in the US). However, these do look different from California material. It would be great to look at these under the scope and see what their cystidia look like.
83% (1)
Recognized by sight: Red-brown to orange to ocher color, growing with pine, decurrent gills. Microscopy needed to assign to species.
Used references: Miller Jr., O.K. (2003). The Gomphidiaceae revisited: a worldwide perspective. Mycologia 95(1): 176-183.

While Miller did transfer this from Gomphidius to Chroogomphus, in later work it questioned whether this is a good species or if it should just get merged with C. vinicolor. Interestingly C. jamaicensis is another species that has thick-walled cystidia. It would be great to get more documentation on these including which species of pine they are growing with and what species of Suillus (and possibly other boletes) are fruiting close by.
