Nemania aureolutea?
Bohan Jia, 21-01-2026 19:55
Hi, 

Could this be Nemania aureolutea? Or did I found something different? 

on deciduous wood

spores:
13.7 [15.4 ; 16.1] 17.9 × 5.2 [5.8 ; 6.1] 6.7 ?m
Q(L/W) = 2.3 [2.6 ; 2.7] 3.0 ; N = 39 ; C = 95%
Me = 15.8 × 6.0 ?m ; Qe(L/W) = 2.6

asci:
90.1 [109.0 ; 146.7] 165.5 × 7.8 [8.4 ; 9.6] 10.2 ?m
Q(L/W) = 9.1 [11.7 ; 16.9] 19.5 ; N = 4 ; C = 95%
Me = 127.8 × 9.0 ?m ; Qe(L/W) = 14.3

Best Regards 

Bohan

Re : Nemania aureolutea?
Hi, Bohan - 

could well be but you should check your sample for a "fugacious greenish or greenish-yellow hyphal layer around the perithecial mounds" and / or a yellow stain of the substratum below the perithecia. (see pyrenomycetes. fr., here cited). 

regards from Bavaria

Re : Nemania aureolutea?
Hi Till, 

I made some cross-section of the stromata and I didn't find yellow pigment in the substrate. Furthermore, I realized that there was visible germ slit on some of the spores. So I think it's not Nemania aureolutea but Nemania aenea then :). Thanks for the tip. 

Best regards 

Bohan

Hello Till (and Bohan)
thanks for the hint with the greenish color. 
I was reminded of an own collection showed here without a reply:
