Who: Paul Derbyshire (Twizzler)

No specimen available

A bolete with blackened and damaged regions. Another one was fairly close by. Both were large, about 8cm tall and 5 wide, with thick caps (over 2cm), and were in Zone 12. I couldn’t get a real good shot of the pores.

Think it really is green.

There is an area of the stipe which is also being colonized by this greenish material. Likely Hypomyces. Might be a new variety. If so, a voucher collection is even more important for future comparison and study.

There was no flash used here. Parts of the mushroom may have been in sunlight though.

First of all it’s yellow but the photo is taken with too much flash?light and

you can see the greenish pores shine thru I think. And second there are plenty of different Hypomyces species all around the American continent which are currently in the process of being investigated and analysed. Even in Europe we have at least two different Hypomyces fruiting on Boletes here.

Could maybe be a form of Hypomyces. I’ve never seen green Hypomyces chrysospermus. Typically I find Hypomyces on B. zelleri, B. chrysenteron, Rhizopogon sps, or (once) on Hymenogaster sps.

As Gerhard has pointed out this specimen is being taken over by a Hypomyces species.

Probably Hypomyces chrysospermus judging by the color changing from white to yellow as seen in the pictures.

Once again infested with Hypomyces sp. and therefore unable to determine

but with what appear to be mis-shapen pores. Could be one of the Gastroboletus or Gastrosuillus. Need to have specimen sliced through the center of the cap, and a close-up of the results, especially the area near the stipe. Also, need to note any sudden color changes of bruised or cut flesh.
