Observation 119599: Boletaceae Chevall.
When: 2012-12-09
No herbarium specimen

Notes: boletus, aeroboletus, boletus citrinoporus, whatever it is, this and things very similar to it are everywhere. in the forest, in landscaping. In some woods scattered singles, in some woods, quite large specimens, i’m not sure they are all the same or different, but little boletes like this seem to be THE mushroom right now. in this photo color is fairly accurate.

should have white mycellium at its base according to http://www.mykoweb.com/...
but this had yellow…. it was growing at stevenson college, UCSC, in landscaping with live oaks, probably redwood and ornamental trees nearby. I’m really not sure what these are. I know nothing of retiboletus. Thanks for the input everyone!

Reticulation

is usually not present on X. subtomentosus, but as specimens dry, they will occasionally show the coarse, low pattern like the ones below.

The pores don’t look as bright as I’d expect for A. citriniporus

is probably a dark capped fruiting of X. subtomentosus, but it’s a little weird, I guess it could be an Aureoboletus.

It’s not B. fibrillosus.

B. fibrillosus?

Do you remember which trees were near this one?
Maybe add B. fibrillosus to the possibilities, although it looks more citriniporus.

This reminds me of…

Retiboletus griseus, a predominantly eastern NA species. Kuo says it has been reported from SW NA. Any chance this could be some species of Retiboletus?
