Hmmm, interesting ...

Hi Jenny,

so this is you taking on Dorset now.

I think this is a good candidate for subsp. uncialis, but as you say, you need to examine the central canal.

An interesting parallel is the fungus Geoglossum arenarium. It has a few other northern localities, but substantially it is a species of the same acid dune systems as C. uncialis subsp. uncialis. It also has one locality in the south - Studland!

I'll be interested to see any further developments.

Looking at this again

Looking at this again, with brain switched on and post-coffee, this does look like perfectly good subsp. biuncialis, as Neil has confirmed.

Kicked myself

Kicked myself for not getting a specimen but I was out looking for micro-moths and desperately trying not to notice all the Cladonia's! Knew they'd grab a hold of me again though .......

I've got about half a mile of path to search but when I re-find it I'll post further details.
The NBN map shows a site in Hampshire so I might get in touch with Neil Sanderson and see if he can tell me more about possible Dorset / Hampshire distribution for subsp.uncialis.

Curious that Geoglossum arenarium only southern site is also in the Studland area - is this just coincidence or is there some underlying similarity in the dune systems?

Specimen

I collected and sent a specimen to N Sanderson and it turns out that the NBN record of C. uncialis uncialis is an error.

From his comments on my specimen:
"....not as neat as the sp uncialis I have seen, is actually a bit powdery inside the medulla and is UV + white (sp uncialis is rarely UV + according to the LGBI, which seems a useful definitive character to go on), so probably just tall ssp biuncialis."

Pity. I was mildly hopeful!
