Simon GurtnerGood evening found on 25.03.2024 in Bern, Switzer
Vast numbers of this asco found on 2-3 year old burnt ground in a eucalyptus forest; stipitate when small, flattening with age up to 1cm with a fringe of hairs.
Spores are smooth, 23-24 x 13-15um, encased by a warted membrane when immature.
Asci are Lugol's -ve and have a simple base.
Hairs are hyaline at the top, purple/brown at the base, septate with walls approx 2um
Thanks

Why not a Pseudombrophila?
A close-up view of ascus base should be interesting.
dans le cas des ascospores, un épaississement visible peut être observé aux pôles. Est-ce peut-être une caractéristique déterminante ?
Un bon moment
Ursula
I am unable to access Otto's database 'In vivo veritas', is it no longer available?
vous montrez principalement des ascospores dans la section optique (optischer Schnitt). On ne peut pas juger si les éperons sont ou sont sans ornement.
Si les spores sont ornées, ce serait bien si vous pouviez les montrer au microscope dans l'eau.
Un bon moment
Ursula
I haven't seen any ornamentation on the spores themselves only on the sheath surrounding them.
Cheers
Peter
Peter sent me a receipt. Microscoped and documented the Asco find. Was able to add some microscopic features to Peter's post. Here my results.
Macro
Very strong hair growth on the outside of the fruit body, especially on the edge, can be seen on the exsiccate. Hairiness down to the stem area. Compare it to a felted fabric. Page 2 - 3
Micro
Spurs:
Hyaline, smooth, thick-walled, partly in gel shell, 22.5 - 25.5 x 13.5 - 15.5 µm Q 1.7 - Page 4
Germinating spores – conidia:
Germinating spores with pinched conidia, conidia 11 – 13.5 x 2.5 – 4µm – Page 5
Paraphyses:
Expanded above, up to 7µm, brown pigmented, partly hairy – Page 6
Asci:
Eight spores, 280-320 x 18-21µm, base without hook, J-
Fabric layer:
Textura angularis, very compact, cells 10 - 30 µm, hyphae of the texture up to 3 µm - Page 7
Hair:
Outer area of the fruit body and edge very densely covered with hair. Hairs hyaline to beige, up to 6 µm thick, walls 1.5 - 2 µm thick. Hair on the outside 160 - 270 µm long.
It was observed that the hair in some areas, especially in the edge area of the fruit bodies, was heavily covered with gel. Pages 8, 10 - 14
Attached is a 14-page documentation of the find. Unfortunately I am not able to identify the find. I would particularly like to point out the gel-coated spores, the heavily gel-coated hairs and the very compact layer of tissue. I moved away from my first thoughts about Geopyxis because of the strong hair on the outside.
I give the Asco the working title Pseudombrophila.
A good time
Ursula

beautiful documentation! Now I am sure that it is indeed a Pseudombrophila.
Best, Uwe
I thank you and Uwe for answering on this one.
Cheers
Peter
kann dich leider nicht per Mail erreichen. Hat sich deine Adresse geändert?
Wäre schön von dir zu lesen.
Eine gute Zeit und bleib gesund
