Description:

Rather mystified by this bolete (Leccinum). Was in mixed scots pine/birch/poplar woodland, these were actually nearest the poplars. Do distinctive taste i.e. not bitter. There were L. versipelle around and these were clearly not that species nor L. aurantiacum (unless that becomes more brown as it goes well past its best). It was the brown stem and brown cap that were difficult to explain.

There has been some

There has been some interesting discussion of this observation and http://www.ispot.org.uk/node/227061 at the mushroom observer website, see:
http://mushroomobserver.org/observer/show_observation?_js=on&_new=true&i...

There is a suggestion that this is Leccinum aurantiacum and that other ispot observation is L. albostipitatum. Still not sure I entirely agree with this, however I had not realised that L. aurantiacum under poplar had been split into two species, the other being L. albostipitatum with a paler stem and somewhat brighter red cap.

I may be wrong here but it appears that L. quercinum has vanished into L. aurantiacum and that L. albostipitatum has come out of L. aurantiacum all due to molecular methods. It appeared that that there was no difference between L. aurantiacum and L. quercinum at molecular level so just collapsed them into one species. From UK perspective it seems L. albostipitatum is generally a northern species but this needs to be confirmed so keep eyes peeled for any orangish capped leccinums and take plenty of photos of the cap and details of the stem and preferably at all different stages of development. could also look at any colour changes when cut.
