Cystodermella granulosum

I found this one yesterday, and thought it had a Cystoderma look to it. On a brash pile of Pinus sylvestris and bramble. I was hoping it was Cystodermella cinnabarina, and found a whole load of cheilocystidia, only they were the wrong shape, and the spores were too big. Then I realised I'd taken the gill squash from a young similar looking fungus from a different collection, which is a different fungus entirely, but the cap and veil details I'd taken from the right one. No wonder it didn't fit anything ... It was only when I checked the spore print that I noticed that the cap had dried much lighter on that one, the spore print was pink, and the gills and turned reddish that I'd realised my mistake. And I was just about to post too, otherwise my face might have turned reddish too .... you can see the wrong spores and cheilocystidia on the archives ... (Now I've got to work that one out, though I've done some of the work ... )

Anyway I managed to get a gill from the correct one, but sadly no cheilocystidia of C cinnabarina, as they look quite dramatic. So I guess that makes it Cystodermella granulosum. It is just as pretty though macroscopically ...

The cap had lots of these tiny pieces of hyphae, which look cuboid, though they could be cylinders I guess. Is that the way the hyphae disintegrate, or is this what is meant by the term paraderm or conioderm? And how do they differ from arthroconidia?

And I also wondered why the spherocysts didn't change colour in the KOH I put on them ... derr ... it was NH3 I was using. My brain forgot to get up today ....

Its a nice find that mushroom. I thought I had found some as the stems looked similar. In fact what I had found was Hypholoma marginatum. Anyway my Collins fungi book describes this mushroom as a protected species. Is it quite rare in the British Isles?

Cystodermella cinnabarina is a red data one, 'Rare (Red Data List, ed. 1); Near Threatened (Red Data List, ed. 2)' but Cystodermella granulosum is apparently 'occasional' in Britain. I'd also like to see Cystoderma superbum, partly because the name makes me laugh as I imagine it walking down the catwalk, and also because that has only been found once in the UK ...

And if you are confused (well I was), it seems that some of that were formerly in the genus Cystoderma are now in a genus called Cystodermella. Though this isn't shown on the British basidiochecklist yet.

Hallo Mel,

cystoderma granulosum also in germany is quite common, the 3rd place after C. amianthinum and C. carcharias. C. terrei is wuite rare, and so is C. superbum. Nevertheless I have a location were I find it every year in good quantity, I think 50 to 100 fruitbodies always.

What concerns the other fungus you found with the pink spore print I would compare with Rhodocybe nitellina.

The cylindric elements in your micro foto I have never seen. I'm wouldn't be too sure that they belong regularily to your Cystoderma.

best regards,
Andreas

Hi Andreas
The other fungus I found was ... wait for it ... Tubaria hiemalis ... it was a very young one that I had got mixed in, the red top and bits of veil were quite similar. The big mature Tubaria were almost white on the top, and looked so different from the Tubaria furfuracea I'd been finding on the hawthorn kernels in both size and sturdiness, even cap shape that I didn't recognise them. The cheilocystidia were very familar though, the first thing I thought was that they looked like Tubaria furfuracea. And the spore print colour in daylight has a golden tint to it, doesn't look quite so pink, though there is a definite pink undertone ...

C superbum do deserve their name, they are very attractive indeed (and I see are dressed in this season's fashion fabric and colour too ...) Those in your photo are in perfect condition. I expect that is the closest I'll get to seeing those, but I'll now certainly recognise them should I be lucky enough to happen upon them.
