Any ideas? Forked, crowded slightly decurrent white gills.

Taken from a wooden pot outside my house, the cut specimen inside for 4 hours, the other taken by flash still in the pot.

Hello,

just from looking at the fotos I would have guessed Tricholoma fulvum. But you said they are from a flower pot and that the gills were white (not yellow as on the foto), so I'm quite certain that it is a Melanoleuca species.

bestr egards,
Andreas

Hi Lawn

Maybe Melanolueca? What kind of size were they?

Cheers, Nick.

Beaten to it by Andreas.

I've found a lot of similar looking specimens recently.....

But despite research have not come up with a species yet, but the adnate/decurrent gills seem to be a good clue!

Cheers, Nick.

Thanks all, am liking M. melaleuca aka M. polioleuca for this one, seems that the stem is somewhat fibrilose which seems a good identifier.

4 to 8cm diameter.

Didn't know M.polioleuca & M.melaleuca are considered the same species.

I'm happy yours and mine are the same (mine being a little outside normal size range- 15 cm cap diameter)

Another puzzle solved

Hello,

noone will know whether those two are the same and which name they should have without having investigated them by microscope.

Whether M. polioleuca and M. melaleuca are synonymous depends on the interpretation of M. melaleuca, being interpreted as a species without macrocystida by BOEKHOUT, but with macrocystidia by KÜHNER, BON and many others. As BOEKHOUT defined melaleuca as the species without cystidia, he had to give the one with cystidia another name: M. polioleuca. BON and many others say that melaleuca is with cystidia and therefore had to give the one without cystidia a new name: M. robertiana.

best regards,
Andreas

OK thanks Andreas, not quite as simple as I assumed!

So seeing as the specimens In my photo did not have cystidia I could call them M.melaleuca (sensu Boekhout- which seems to be the approach taken with the 'British and Irish Mycota Checklist') ??

Cheers, Nick.

Hello Nick,

no it's still not that easy. It is very probable M. melaleuca ss. BOEKHOUT if it has no cystidia, but that is not the only species without cystidia. There are others, some quite porly known, and for determination one has to take all features into account. And still often doesn't succeed in finding a suitable name.

best regards,
Andreas
