I can find no suitable answer for this white Bryoscyphus with such spores. The stipitate apothecia growing on indeterminate decaying mosses. Asci IKIb croziers (+).

Re : Bryoscyphus

I can only think of B. rhytidiadelphi in which the pattern of the LBs may have been altered. But when I made the preparation, the asci released a multitude of very mature spores, which seemed very normal.

Michel Hairaud, 04-07-2022 19:14

Re : Bryoscyphus

Hi Enrique, I suppose you also considered B. phascoides , which spore guttulation pattern is similar ? (though a little thiner in my collections)

AmitiésMichel

Enrique Rubio, 04-07-2022 19:29

Re : Bryoscyphus

I see the spores as very different, Michel, and also the gutulation.
Merci

Michel Hairaud, 04-07-2022 19:39

Re : Bryoscyphus

Ah , which means I made a wrong identification on this collection !

Enrique Rubio, 04-07-2022 19:48

Re : Bryoscyphus

Your spores look identical to mine, but the gutulation pattern seems different from rhytidiadelphi unless the small LBs quickly rearrange and form larger guttules.
On the other hand I have been told that the moss in my collection looks like Rhytidiadelphus

Enrique Rubio, 04-07-2022 19:52

Re : Bryoscyphus

Svrcek's drawings show small guttulae

Enrique Rubio, 04-07-2022 19:54

Re : Bryoscyphus

And also my older collections of rhytidiadelphi.

Re : Bryoscyphus

Similar to mine rhytidiadelphi (very common in winter on the coast ) but never found with the guttulation you show . I will send you later my whole file for my misidentified collection of B. phascoides

Re : Bryoscyphus

Enrique, I suggest to identify the moss. perhaps you can make a preparation of a leaf to show the cell shape at base and apex, presence of a midrib, structure of margin. Perhaps someone can tell. Was the moss also uninfected and do you have a photo?

Georges Greiff, 23-07-2022 18:26

Re : Bryoscyphus

Moss could be R. triquetrus but a photo from further away would help to be sure. B. rhytidiadelphi does not seem to be specific, however, or at least there are reports on other hosts. I had convincing material on Bryum argenteum once.

Enrique Rubio, 11-08-2022 13:16

Re : Bryoscyphus

Hi again
My friend Marta has studied the moss and she thinks it could be R. triquetrus, as Georges wrote.
What do yo think?
