I could send you a sample.

I don’t have access to facilities for sequencing myself. The key in Wu et al. puts this in either Xerocomoideae or Boletoideae based on its yellow juvenile pore surface. Xerocomoideae seems more likely and within Xerocomoideae Hemileccinum seems like a pretty promising place for this.

Nice analysis

This bolete has a mixed morphology, but I do agree that it’s more in line with that of Leccinoideae. Are you going to submit this for sequencing? If not, would you be willing to send me a small cap sample?

contains species formerly placed in Tylopilus and sequestrate species. Other than the sequestrate species, all species currently in Zangioideae have whitish or pinkish pore surfaces. There are species in Leccinoideae with yellow pore surfaces. The stem base is similar to that of species in Zangioideae, especially Harrya, but overall I think this fits better in Leccinoideae. I don’t know of any species in Leccinoideae with yellow stem bases, but since this is a feature that occurs in both Chalciporoideae and Zangioideae, I don’t think it’s unlikely that it could occur elsewhere.
