I see no reason why

it shouldn’t occur in Scandinavia (although it was originally found in sawdust in Switzerland), that’s why it’s frustrating not to have it in the keys in my new “bible”, Funga Nordica.

I know the spot where I found my purple Cystoderma, and I will try to bring a collection home again. I did collect it, but didn’t get it properly labelled and it was mixed up with others after a while..

But I need to find a description of superbum.
Andreas, if you have one, could you add it to this observation? Please?

there seem to be no findings in scandinavia yet, not even in Denmark. The species was originally described from Netherlands and was foremrly misidentified for Lepiota haematites, which is in fact another species with bigger spores. It was HUIJSMAN who described it, a far as I remember. It occures in Great Britain, and should at least to be found in Denmark too. So Sweden is not impossible of course.
Hopefully you know the location and can come back next year to cellect it? And don’t forget to make a herbar specimen …

Outrageous…

The chapter with Cystoderma/Cystodermella in the new “Funga Nordica” is (for some reason) written by an estonian mycologist, and superbum isn’t even mentioned there!

Btw, Cystodermella granulosa was proposed by Harmaja to be the type species of the new genus..

Cystoderma superbum!

Dear Irene, judging from the foto this should be indeed C. superbum, not granulosum. Where to range this species in the two-genus-conception of HARMAJA is unsure. This species has spores, which are inamyloid, except a small suprapicular zone. So except a kind of amyloid “plage” the spores are inamyloid, but in mass the amyloidity is seen (not tested by me, but will do next year). In Scandinavia there are some more species then in Central Europe. In the journal SIENILEHTI there once was a nice overview with marvellous fotos, I think by KORHONEN. But unfortunately in finnish ….

Hmm, not known in Scandinavia

but if you saw this one:

Would you judge from the colour and call it superbum?
Well, I certainly have to find a description of it – somewhere..

the colour is completely different

it’s a marvellous pinkish wine-red (or whatever one should call that colour …)

Oh, new one to me

How does it differ from granulosa (more than amyloid spores)?
