What species are present in the West is less certain. It turns out that some specimens identified as S. lactifluus growing under hard pines in eastern North America are the real S. granulatus too. I misread this part of the paper and probably should have refrained from voting on observations that didn’t mention ecology. As Dave and Igor mentioned in the comments on obs 209030, the paper also didn’t include a type study of S. weaverae, which would have helped to sort this mess out. Hopefully there will be one. If anyone wants a copy of the paper, let me know.
