Jason KarakehianHi does anyone have a digital copy of Raitviir A (
I have two very similar finding last weekend and this weekend. In the first case, these were fruiting bodies on a periodically moist site on the smouldering wood of a deciduous tree (a few metres away, fruiting bodies on the smouldering wood of Salix cf. fragilis). The size was about 50 mm. Yesterday I found a similar fruitbody that was slightly darker and 45 mm. It was on a smouldering deciduous tree at the edge of a forest stream.
I've microscoped the spores that the fruiting bodies themselves "shot" onto a microscope slide, so I think they may have been ripe. The size was almost the same in both cases (difference of about 1 µm in length and 0.4 µm in width). Size: 31 - 39 × 12 - 15 µm (measurements in water). The spores had a faintly visible reticulate ornamentation in the CB. Do you think it could be Gyromitra parma? The "appendages" on the ends of the spores don't look right to me.
das Sporenmaß ist für G. parma meines Erachtens zu groß und die Ornamentation zu eng und zu flach. G. parma kenne ich mit deutlich höherem weitmaschig ausgeprägtem Ornament.
Könnte es G. matinii sein?
Eine gute Zeit

That's very interesting. Fully developed ornamentation, including polar apicules, is present in G. parma only in very mature or overmature spores. And apothecia with a size around 5 cm can be really immature. However, the shape and size of your spores match G. martinii, if that species really exists. I would also look for loaf-shaped spores. On the other hand, G. martinii should prefer wood of Fagaceae probably and rather higher altitudes.
The genus Gyromitra is far from clear.
Greetings, Marek
füge zum Vergleich ein Formblatt von G. martinii an.

I also agree with G. martinii. I found it in 2022 on Fagus, which was apparently the first record for Austria. This year I collected it in two more areas, once on Carpinus, once on Fagus and once on a trunk of an unidentified deciduous tree (possibly Acer pseudoplatanus). It seems to be spreading, which is not surprising for an apparently primarily southern European species. Some photos of G. martinii are attached.
Best wishes,
Gernot
