Possible Cudoniella species at Longshaw

[FungiJohn]

Hello all

I found this possible Cudoniella species at Longshaw growing on wood debris.
Max size - 2.5mm dia, stem 1mm long



Also found was a small group of ‘non bleeding’ spring Mycena smelling of Iodine but quite different to the usual Mycena filopes. I say different, this species can be as varied as the deceiver!



And those gills are not crowded ... Interesting!

Any thoughts or comments appreciated

Hello John,

the first one should be a Hymenoscyphus species. All known Cudoniellas are white (becoming reddish when touched in some species).
The Mycena could be several species. If on coniferous wood it may be e.g. M. leptocephala or single growing stipata/silvae-nigrae. On hardwood it could be M. abramsii. But that are only hints what it could be, there are more candidates for sure!

best regards,
Andreas

M. abramsii is often the first of the years Mycena. Although it doesn't bleed profusely it does contain a watery liquid and your photo shows the cross banding of the stipe that might suggest there is liquid in the hollow stipe.
Having said that I would agree with Mollisia that there are others about and the only way is microscopy.

Many thanks Andreas and Mal

I didn't realise all Cudoniellas were white.

The Mycena was found on hardwood and it did cross my mind that it could be Mycena abramsii too, but as you correctly point out it would require microscopy to be certain.

Hello,

by the way, the genera Hymenoscyphus and Cudoniella are colesly related and there are segregates of Hymenoscyphus, which are more distant from Hymenoscyphus then Cudoniella is. So may be in several years we find a quite new arrangement of the species in this two genera, likewise it has been done with Dasyscyphus may be. Some genera have already split of from Hymenoscphus and may be some species of Cudoniella will become Hymenoscyphus one day ...

best regards,
Andreas

Thanks again Andreas

More changes!

btw Can anyone recommend further books or literature on discomycetes .. other than FoS / A World Monograph of the Genus ..

How about M. purpureofusca - usually Scottish but also found in Yorks (in Dalby Forest May 2002?)

It can be in/on/amongst hardwood as well as conifer and my pic may be a bit lighter than usual. But as has been said, you can't do mycena from pictures without the microscopy.

Also M. leptocephala ?

All very possible Alan.

I'm going back at the weekend to hopefully find more and do a proper job!

Here's another image:

Also found in 2008 in Yorkshire Alan
Both my find and yours show a definite purple cast in both the cap and the lamellae edges and I don't think Johns find shows this.
M. leptocephala more likely but I would still go with M. abramsii
