Looks to me like the last one may actually be Russell's Bolete (Aureoboletus russellii) rather than Frost's Bolete (Exsudoporus frostii). Both have intricately reticulated stems, but the pale brown cap is more characteristic of Russell's Bolete. Frost's Boletes tend to have much more pronounced reds and yellows. Great find nonetheless!
Looks like you are right. The stem seemed way to long and the cap to large for other frostii's I've seen in the past. Also the red color is not on the cap, I figured it might have just lost it with age. Now I wish I had havested it, its listed as a good edible.
@tych021 found some nice fresh specimens of these guys last week.
Yes, I looked)
