Scopinella?
Per Vetlesen, 07-01-2018 22:47
Grown in moist chamber on bark/resin of fallen Pinus sylvestris attacked by Cronartium flaccidum or Peridermium pini. The bark was collected in Hamar, Norway in September last year.
Perithecia globose D ca. 200 µm
Neck 400 x 50 µm
Asci about 14 x 36 µm
Spores (6.6) 6.8 - 7.6 (7.8) × (4.9) 5.4 - 6.3 (6.5) µm; Q = (1.1) 1.13 - 1.3 (1.5) ; N = 22; Me = 7.2 × 5.8 µm ; Qe = 1.2

Is it a Scopinella or another genus?


Thanks in advance for any suggestions and help.
Regard
Per

Re : Scopinella?
Dear Per,

Check Melanospora chionea.  That species is usually on dead pine needles, but I think it may also be found on other pine materials.

Hi,
here is a very good representation of this species.

Re : Scopinella?
Hi David and Peter,
Thank you very much for your suggestions!
Yes it must be a Melanospora.
But it differs from the description of M chionea, perithecia and spores are smaller, and I have not seen a flattened side on the spores.
The spores looks much like the one presented here: https://www.bio-forum.pl/messages/33/304016.html , but that one is "4-spored".
But I cannot find any species that fits better and I will call it Melanospora sp or Melanospora cf. chionea for the time being.
All the best
Per

Re : Scopinella?
Hi Per,
if I look there at the data with M. chionea, nevertheless, your finding could also belong to it. Or have I overlooked there something or have interpreted not correctly?
Greetings Peter.

Re : Scopinella?
Hi Peter,
You are right; the sizes of the spores and the perithecia are inside the lowest measurement given in the description. It is M chionea.
Thank you for helping and guiding me!
