marismius for id

[tapinela]

this was found yesterday growing in heather on leaves/debris,
the group we were with had suggested it was a marasmius of some sort, but no definite id was arrived at,

the largest one was approx 10mm and about 20/25mm tall, and had no noticable odour, cap felt slightly slimy, but that could have been down to the rain making it appear that way,
looking through my (limited) books, nothing looks obvious,
any suggestions please?



thanks

Hi tapinela

Was it growing on old 'hidden' Russula debris? If so possibly Collybia cirrhata

John

[tapinela]

Hi, that was quick!

no one mentioned the possibilty of an old russula being present?
it appeared to be growing on the actual leaves and twigs but i suppose there could have been something else underneath?

it probably did not get to close an examanation, as it had just began to rain a bit more heavily and there was a rush to get the cameras away and head for the trees

Even quite small remnants of an old (blackened) Russula will support a 'large' group of Collybia cirrhata and it is often overlooked as the host!

you were right with your collybia
one the group has now identified this as being collybia tuberosa,
as it had the remains of a sclerotia (something else that is new to me)on the base of the stem,
which apparently,you can just about make out in my picture?
and which was probably missed at the time due to the mad rush for shelter from the rain
(his picture will be much better than my "cheapo" cameras rain splashed lens one)

thanks

Hellow again tapinela

Yes, a reddish brown sclerotia would indicate Collybia tuberosa

This was an important point Ken pointed out to us on the WAB Clumber foray!

Yes, this is one of the small Collybia species, as John has indicated. Always worth hunting to see if there any sclerotia hidden in the material it is growing on.

You will find several misidentified images on the web labelled as Collybia tuberosa which clearly show the yellow-ochre sclerotium of Collybia cookei, so it is important to check what colour the sclerotia are. I can't make out any sclerotia in the image to confirm the identification.

Here are the two for comparison.





Both found in the same patch of decaying Lactarius.

That's a great find Mal. I usually give up after finding one or two sclerotia. Just shows it pays to be more thorough.
