disco on Phragmites

Bonjour tous

Collected on fallen dead culms of Phragmites australis from the previous year. All images are of living material in water.

Apothecia colourless or with a faint pinkish tinge, no protruding hairs, up to 0.4mm. They are sessile and leave a brown attachment ring, though this may just be remnants of host tissue. The margin is as seen in the final image - without protruding cells/hairs; the terminal cells c. 5-6µm wide.

Asci 8-spored, apex blue in Baralsche Löhsung, with croziers. Quite a number of the asci (at a particular stage of development) with 1-4 "Psilachnum bodies" their size dependant on how many there are. One particular developing ascus (see image) was divided into a number of vacuoles, each with a single globular body - very active (Brownian motion?).

Ascospores mostly clavate, with small droplets towards (but not at) the apices; 8.8-10.8 x 2.4-2.7µm, Qe = 3.8.

As ever suggestions welcome.

Cordialement, Chris

Re : disco on Phragmites
Hopefully someone else will comment as well, but could it be a Pyrenopeziza sp.? It reminds me of P. typhicola to some degree, which I earlier posted here. That one has also those "Psilachnum bodies", but obviously that's another species (dark excipulum, shorter spores, different host).

Re : disco on Phragmites
Apologies for not responding sooner.Thanksfor the suggestion, but I don't think this is a Pyrenopeziza, or near relative. Perhaps someone else has a suggestion.

Re : disco on Phragmites
Salut Chris,

Any chance it could belong in the Helotium microspis group?

For example in Zottos Google Drive files: Helotiales/Pezizellaceae (with VBs)/Calycellina/microspis VBs-

Amités,

Rem acu tetigisti!

I think that is a splendid suggestion and several characters fit well with Zotto's images.

Many thanks, Chris
