Ruzenia/Lasiosphaeria spermoides?
Juuso Äikäs, 15-11-2020 17:08
I found these accidentally while looking at other fungi with a stereo microscope. The substrate is a fallen trunk of Sorbus sp. 

I think the title's species is a promising candidate, although the spores are maybe a bit wide?

Spore measurements (measured inside asci):

(20.9) 20.93 - 27.3 × 4.2 - 5.46 (5.5) µm
Q = (4.5) 4.52 - 6.55 (6.6) ; N = 5
Me = 24.8 × 4.8 µm ; Qe = 5.2

Do you think I'm right? And if so, which one is the more valid name?

Ok, thanks a lot! Then Mycobank has it wrong and Species Fungorum has it right.

FYI...

Hi Andy,

I am not sure who selected Lasiosphaeria spermoides as current name. In the history of the record it is not given.
I have checked both Hilber & Hilber (2002) as well as your publication from 2004 and updated the records and also added the designated lectotype.
