Pholiotina or Conocybe

I've been round and round in circles today, with something that I thought looked very like Conocybe. And using Funga Nordica drew a complete blank. The cheilocystidia weren't the really typical perfume bottle shaped ones. In the end, I flicked my way through FOS and thought Conocybe aporos looked very like it, and found that it comes under Pholiotina in Funga Nordica, which is why I couldn't key it out under Conocybe

And it does key out to Pholiotina aporos, with ring and no obvious pore in the spores. I then checked on the British checklist and in Britain we have it under Conocybe.

Just wondering why Britain is out of sync with Funga Nordica, which is one of the most recent books, and where it is most likel to end up.

(And I've just pencilled in Pholiotina into Archie McAdam's key so I don't make that mistake again ....)

hi Melanie

if you remember we found Pholiotina aporos at Anston Stones Wood around this time last year (near where we had lunch in "Yew Alley"

the disposition of species into genera - and indeed into any higher taxa - is a matter of opinion; as I have hinted at in a number of recent posts I'm sure that we (in the UK) will soon accept Pholiotina as a valid genus; it has been a subgenus of Conocybe for years now, for example in British Fungus Flora vol. 3, page 91 (which I think you have? - I would never use Fungi of Switzerland as a key to Conocybe species - too many species not in it, good for confirmatory pictures later, but don't underestimate BFF))
given that, as part of the series of Fungi Europaei, Anton Hausknecht has recently published his splendid major monograph on Conocybe and Pholiotina in Europe (Edizioni Candusso - ISBN 88-901057-8-X) which is likely to be the last

word on this group - at least for a decade or two, I think that Pholiotina will soon be the name we use for annulate etc Conocybe species in the UK - but of course the fungi themselves don't change; and it does require a certain amount of work to rename older records accurately . . .

on a very modest front I am currently trying to produce a checklist of fungi recorded in Yorkshire (with full synonymy!) and it is a nightmare, dealing with older lists/names and attempting accurately to place them into current nomenclature - I mean where did the Helicobasidiales and the Atractiellales come from

; such tedious 'backroom' work does keep you out of the field collecting, so have a little sympathy for the 'behind the scenes' mycologists!

but I have bitten the bullet and am treating Pholiotina as a good genus ahead of FRDBI doing it (because I know they will

)

I'd forgotten we'd found it there ... I didn't take one to check which is probably why I've forgotten it - it's the ones that I spend time agonising over that have a chance of registering a little marker in my brain

I'm putting them in my database under Pholiotina (which automatically 'corrects' it to Conocybe), so hopefully that'll help my memory ...

No I don't have BFF yet. It's on the wanted list .... FAN 6 (which I have) separates Pholiotina from Conocybe too, and seems pretty good.

I was flicking through some of my older Galerina photos/microphotos yesterday and I discovered one that I'd been unable to id which looks as if it is another Pholiotina ... the give-away was the spheropedunculate cells in the cap which should have told me it wasn't Galerina at the time. And I'd dismissed it as a Conocybe because the cheilocystidia were not skittle shaped ... I think I fell down that same gap between the English and European keys, so missed out Pholiotina as a possibility. So that's one I'm now hoping I can pin down .

And today I've picked a couple of rather small fungi that look to be either Conocybe/Pholiotina or Galerina so that is this evening's challenge (along with one or two Psathyrella and some Panaeolus/Panaeolina).
