For now I suppose it’s a “take your pick” situation with the names, though it looks to me like “flavidus” has the upper hand at this point.
S. umbonatus is an american name, flavidus european. I guess they are both current names because they still haven’t investigated them. But I beleive now that they are synonyms, and apparently not possible to tell apart by macro or micro characters.
I don’t know if anyone has tried to prove if they are separate or synonyms by looking at their DNA yet. One problem is that many Suillus species are cloesly related and differ very little in the ITS region.
When I compare sequences umbonatus/flavidus from european and american collections, they look the same to me – they differ by one or two nucleotides, but that is from collections both within and between our continents, and not always the same position in the chain.
I know this as Suillus flavidus. The literature I’ve checked is conflicting on the relationship of the two names. Separate or synonymous? IF and Mycobank list both names as valid. Kuo suggests synonymy as does Miller. Bessete et al in North American Boletes say Moser placed the two in synonymy in 1997. “Flavidus” is the older name. If they are separate, how do they differ?
