A few stump dwelling fungus IDs please

[funkyfungus]

Hi All, wondering if someone can help with the following:

I'm guessing clavulinopsis helvola for this one





This next one was found on a semi-submerged log on the edge of a lake. Maybe some sort of Laccaria? I did consider that it maybe a species of Collybia but the gills didn't appear to be particularly crowded.







Finally, I recently discovered these fairly small bracket fungi growing on a decaying stump in my garden! Texture quite slimy, peeled easily. (Sorry these photos didn't turn out as well as I'd hoped.







Cheers

I think No3: Crepidotus mollis.

I think 1 could be calocera cornea because it seems to growing out of the wood but I could be wrong. these coral fungis are hard!


number 2 looks a lot like collybia butyracea but has gone white. was it slimy when you touched it?

Thanks for your responses. I agree with you KeenTeen 17, the second one does look very similar to collybia butyracea, that was one of my initial thoughts. However, I seem to remember that the gills are free from the stem in collybia butyracea (I may be wrong though )

Cheers

spot on KT17 with one of these

Clavulinopsis species on wood? no . . .

it doesn't look like Calocera viscosa (on softwoods) - there are other Caloceras but I think you are - as I say - spot on

I don't think we're dealing with Collybia butyracea though . . . it looks like a Mycena I might suggest M. pura from the colour, but it's clearly on wood (and what the fungus is growing on is important with Mycena) I hope others come in on this one because we should be able to get close . . .

I think you are right with Mycena. The colour and form fit much better with pura. The number of lamellula is right for pura and wrong for galericulata but the number of fruitbodies and the fact that it is growing on wood takes us back to galericulata so not much help there then

Thanks again everyone for your advice. I'm a little dissapointed that I was so far off the mark with my thoughts but I've learned something new - which is great. If I stumble across yellow coral fungus growing on wood in the future, I can eliminate clavulinopsis helvola. Thanks KT 17

Can anyone explain to me the characteristics of the 2nd picture which make it a strong candidate for being a mycena? I thought it was a laccaria, which was obviously completely (and rather embarrassingly) wrong . Are there any distinguishing features I should look for in Laccaria in order for me to improve my ability to identify this species more effectively?

Don't be too embarrassed about getting this wrong(if indeed you are).
The Laccaria it possibly could be is laccata. The whole fruit body starts out a deep blue/purple and as it ages fades especially on the cap to almost white on occasions but the gills usually retain the blue colour. When a fruitbody gets waterlogged it can play havoc with the colours sometimes but yours still does not seem to be right. The fruit body and stem are the same size for both the larger Mycena and the Laccaria but in the latter it is more fibrous and in your case it looks semi transparent. The caps on Laccaria tend to be depressed as against the umbonate cap of some Mycena. So all added together it is probably a Mycena.
Having been asked to justify is quite a challenge sometimes but it helps focus on what features you are looking for, unfortunately it also shows up how different books have different descriptions for the same fungus
Hope this helps a little

Ps see the post on A-Z as a result of this

[Chris Yeates]

as far as I understand the position Laccaria is a mycorrhizal fungus

it is - as I have indicated in the Laccaria thread tonight an interesting genus - related to the truffle-like Hydnangium carneum with the latter and also Laccaria fraterna the Eucalyptus Deceiver 'connected' - literally - to Eucalyptus spp.

for fungi to produce fruiting bodies there has to be a 'trigger', this could be climatic, temperature-related, food source related (an abundance? a lack?) or chemical (think of the way that chalk is used in 'casing' - triggering - the fruiting of the supermarket 'mushrooms')

I have heard it said that wherever a Laccaria is fruiting urination is involved, as the trigger (presumably mostly non-human but I would welcome WAB fungus-people to do experiments on their home patches!)

anyway Laccaria on wood - I doubt it

Thanks Mal & Chris

That was not only informative but also very interesting.
