Water fungi puzzle?

[diggleken]

Hi all,
this is, I think (!) Tubaria spp, possibly hiemalis or furfuracea and I would appreciate confirmation of one of these two, or something else of course.
The surprising thing is that this was a solitary grower in still water of an overgrown canal and its substrate and bottom of stem were in the water.
Substrate, very black and rotten, was a bramble twig.
No outstanding smell, but there appear to be veilar remains on the stem, which is throwing me a bit - if tubaria, should there be some there?
And in water, not just damp, but in water - not seen that before.
edit - forgot size - about 1 - 1.5'' across cap.
Many thanks for comments.
Ken

hi Ken

I shall post on some real water fungi soon; interesting occurrence though - one would think that in water the chances of having your fruitbody disturbed would be high, must be a very still patch!

Some velar remains on the stem does not rule out Tubaria; I'm sure Andreas will have something pertinent to say

cheers

Hallo Chris,

This will interest me particularily, because I investigate freshwater discomycetes since several years now. There are quite some undescribed species down there in the water, and of course you have there Mollisia too

No he won't, because he is not really sure, whether this is not a Laccaria. The gills a very distant and look quite thick when watching the bigger picture and the cap structure doesn't look like Tubaria either, nor does the gill attachment. May be the velar remnants on the stipe are only fibrills from the stipe the got loose.

best regards,
Andreas

hello Andreas

I thought Laccaria was mostly a mycorrhizal genus - am I wrong in thinking that?

Hallo Chris,

that's right, and that's what disturbes a little for Laccaria. Therefore I said I wouldn't guess what it is.
But growing on/at wood doesn't necessarily mean that the fruitbody is saprobiontical. Often the mycelium just grows there, and you can often find Tylopilus felleus or Xerocomus badius growing on rotten wood.

best regards,
Andreas

Hi guys, I suspect not, but would it help if I posted some more photo's of it?

Hi Ken,

may be it helps, often it does!

best regards,
Andreas

thanks Andreas - will do later when home from work.

Ken is there a possibilty that the bramble twig and the fungi was originally on dry land and has somehow fallen into the water after the fungi developed??
if that was the case, it would seem more plausible to be either Tubaria or Laccaria,
just a thought that might throw a bit more light on the subject.

Hi Brian and everyone, thanks so far! - further pics below.
Good thinking about 'finding' its way there, but it was originally buried under reed leaves, Typha, so I doubt it.The twig was so blackened, clearly from previous years growth, that it must have been in there a good few months - it was in standing water, but just below the surface -this pic is after I replaced it.
do I need to go back next week do you think?
If so, what should I be looking for especially?
cheers
Ken
