Claussenomyces atrovirens?

Hi!

Black (when dry), solitary or somewhat clustered, sessile to very short-stipitate apothecia on dead, decorticated branch of Pinus sylvetris, Central Norway.

Asci 75-125 x 12-18 microns (in water), IKI-. Asci mostly with granular contents, but a few beginning to form septate spore, difficult to measure presicely. Paraphyses agglutinated in a greenish/olivaceus matrix (resinous material?), apparently with transverse, elongate "bodies". Subhymenium brownish.

I wonder if Claussenomyces atrovirens can be this dark when it dries.  Is Patellaria atrata an option?

A few more photos. The last photo is in Lugol.  The rest is in water.

Re : Claussenomyces atrovirens?
Dear Edvin,
This is Tympanis. I cannot see the primary ascospores. Do you have the collection dry and are you going to keep it in your own herbarium? if so, I would like to know if you do not mind to send me a piece of the collection with some mature apothecia. I am working in this genus and I would like to study the morphology and get sequences. If you are interested in help me you can write me an email to lquijull@gmail.com and I can explain you more if you are trying to identify the species by yourself
Best wishes
Luis

Re : Claussenomyces atrovirens?
Of course! I studied Tympanis alnea the other day and I knew I had seen this kind of asci recently.  I just couldn't couple it to Tympanis because this one looked so different, macroscopically.

The speciemen I have at hand is a duplicate.  I will check with the finder how much more material there is.  I am sure he (Håkon Holien) will be more than happy to provide you with mature apothecia.

I will connect via email.  In the meantime - thanks!

Re : Claussenomyces atrovirens?
Thanks Edvin. Tympanis is very variable in its macromorphology, apothecia can be brown-orange, green or black and solitary or aggregate, whit or without white pruina over them. I will be happy to talk with you or your collegue about the collections that you have.
Best
Luis
