T. indecisus lives up to its name, then, doesn’t it?

Second a vote for Tylopilus…

I would second the vote for Tylopilus. Looking at the Thiers book on Boletes of CA, there are really only 3 Tylopilus to worry about in CA, T. pseudoscaber is very dark all over, T. indecisus is light colored with a reticulate stipe, and T. humilis with a dark cap, light stipe, and only reticulate at the very stipe apex if at all. So, that really puts into T. indecisus area.

Although if that is true, this is really different from what I saw in the east that was kinda id’ed as T. indecisus. Which makes me wonder if this is really a different species (yet another species sensu Thiers here), or if T. indecisus is much more variable than thought, or that I really have no idea what T. indecisus really is supposed to look like.

It is probably the last one…

pores look like they turned pinkish-brown, so it can’t be Leccinum. Nice to have material of all ages for ID!

what features did he use to eliminate barrowsii?

I could find no other pictures anywhere of this species, altho it definitely fits the description. it would be great to have it in the Thiers herbarium at SFSU…;)

Looks like a Leccinum. Maybe L. barrowsii ?? Did you get a spore print or look at the microcharacters? Interesting collection!
