Authority for identification

Yes, Hebelomas, and I would say two different species.
The Cambridgeshire one MAY be velutipes (syn. leucosarx) and the Bucks. one MAY be sinapizans.
However, for positive ID of this Genus you almost always need to check spores and cystidia (and have a good modern key such as that by the late Jan Vesterholt).

I'd never heard of Jan

I'd never heard of Jan Vesterholt until today but Googling led me to MycoKey: http://www.mycokey.com/newMycoKeySite/MycoKey3FAQ.html

I haven't tried MycoKey, but there is free cut-down version and with the 40 Euro licensed version you get keys to "almost all genera of Basidiomycota and discomycetes (Ascomycota) from Northern Europe. It contains almost 900 genera, including polypores, club fungi, corticiaceous fungi, jellyfungi and the operculate and inoperculate discomycetes. It also includes many hundreds advanced characters, (e.g. microscopical characters), more than 4,000 pictures, 17,000 references and the ability to analyze the chareacter sets of different genera against each others. Starting with MycoKey version 3.2 all analytical species keys from the Funga Nordica project is included in the Installed MycoKey (licensed version only)."

Free MycoKey

It might be interesting to try this out before spending €40.

Thanks for this tentitive ID,

Thanks for this tentitive ID, would be good to get people from abfg involved in ispot too.

That would be a good idea

It would be helpful to know the techniques involved and how to proceed. I may have missed something, but I have not seen this explained.

Do you mean the microscopic

Do you mean the microscopic examination? There has been some discussion of this in the fungi forums. You need a reasonable high power microscope.

Thanks, I will have a look on the forums

I do already own a reasonable high power microscope (from the last century).

Here are some links to guides

You can get the stains and reagents from ABFG.

If your microscope isn't calibrated you'll need a slide with a scale on it and a measuring eyepiece.

I can view and measure spores but so far basidia and cystidia (and any other ..idia for that matter) have eluded me.
