I fownd this species in an old, fallen tree (Populus spec)


Can anyone give me a clue in which direction I have to search to determine this species correctly?


Thx.

Bonsoir William,


The white stipitate apothecia with granulose hairs match the genera Lachnum


You will also have to look for absence / presence of croziers ,  the exceeding length of the paraphyses above asci .


Amitiés

Thx, Michel. for your  excellent hint.


I will look further, but I have (as a beginner) still some difficulties to isolate asci to see these croziers.


Cordialement,


William

Re : Hymenoscyphus? Dasyscyphus?

Trying to identify this species of Lachnum (?) I'm faced with the problem to observe those croziers.


I think there are no croziers to see on the following pictures. Am I right?

Re : Hymenoscyphus? Dasyscyphus?
This is Lachnum brevipilosum. The warted hairs are typical of the genus, and the many drops in the paraphyses typical of this and some other species, all of them changing their colour to red-brown due to oxidation of these droplets.

Now I see your new series of pics. Although yoiur first macro shows well-developd apothecia and L. brevipilosum is a winter species, it seems the hymenia are overmature. I did not see a clear ascus on your pics, and paraphyses are always simple-septate.

If you have it still fresh, take a younger apothecium, this is better to see the croziers. But L. brevipilosum hasn't, which is more difficult to verify.

Many thx, Zotto!


With this knowledge I try the key again.
