Yellow disco with curved septate spores and fringed with hairs
Steve Clements, 10-04-2018 16:48
Bonjour,
Trois ascocarpes, jaune vif, jusqu'à 0,7 mm de diamètre, étaient sur bois mort. Les spores sont courbées et cloisonnées. Je l'ai cherché chez Fungi of Switzerland, Ellis & Ellis et Peter Thompson, mais sans succès.

These 3 small bright yellow discos were on dead wood (in mostly oak and birch woods but in the vicinity of alder and sycamore). Possibly on old pyrenomycete, but not sure.  Ascocarp diameter up to 0.7 mm. Sessile. Hairy. Spores mostly curved, up to 22 x 5 um with at least 3 septa. Asci blueing in Meltzer's. e.g. 75 x 7 um. Paraphyses thread-like but irregular. Hairs 5 um wide filled with small refractive droplets.
I am unable to identify this lovely little disco - but I'm sure it must be well-described somewhere.
Cordialement,
Steve

Re : Yellow disco with curved septate spores and fringed with hairs
Hello Steve,

This looks like Calycellina ochracea. Species 300 in my book and fig. 6 in Ellis & Ellis.

With Best Wishes,
Peter.

That looks like it Peter! Can't see for looking. Another new one for our area round Sheffield. 
Many thanks indeed,
Steve

Hello together,


very nice and interesting species, not known to me by now.


As the paraphyses are full of small guttules, it seems to be not a typical good Calycellina to me.


Best regards, Lothar

Re : Yellow disco with curved septate spores and fringed with hairs
Hi Lothar,it was the interesting hairs (not the paraphyses) full of guttules which made me confused! I got the photos of hairs by laying a whole ascocarp face down and squashing it.

Hi Steve,


ah - sorry, I misunderstood this. I see, the paraphyses are (all?) empty ... - but so without a conspicuous vacuolar body, also.


I still think this is not a good Calycellina.


Best regards, Lothar
