Very unsure about this!
A single "gasteroid" fruiting body afoot Carpinus betulus, deciduous forest with quercus and fagus aswell, calcerous soil. Slightly buried in the ground.
Pleasant, slightly sweet to fruity smell (almost like sweetened milk).
Fruting body: Somewhat spongy to the touch but still firm, not lactating, ca. 2cm in diameter with a central rudimentary "stipe".
(Ripped/kicked by accident, didnt think this to be a fungus, looked more like a small pebble at first.
Took a small sample for research purposes, the Rest was left in place of course.
Also, sorry for the subpar in-field pics, definitely was 'a bit' too humid for my phone cam to handle😅)
Subglobose to somewhat ellipsoid Spores:
8,8-(9,6)-10,8μm x 7,4-(8,0)-8,8μm ;
Q: 1,07-(1,20)-1,29
n=12
Spikes on spores around 1 μm They are amyloid/positive in melzers' and seem to be seperated, but need confirmation (=/= somewhat fused like in R. Candidissima acc. Vidal et al. 2019?? https://europepmc.org/article/med/31551617 ).
Basidia: 2-/(3-?)spored
P.calyptriformis??? Again, just getting into waxcaps and relatives, also only found those 3 fruiting bodies, so didn't want to pick any.
In roots of overturned spruce
Birch forest with some spruce
Smells of nothing
Dry felty hydrophobia cap
I think.
Marius Poenariu and Alexandra Dorohoi mentioned some similarities to the Peziza genus.
