Mytilinidion on Picea
Juuso Äikäs, 27-02-2022 13:11
This Mytilinidion(?) species was growing at the black, resinous base of a dead, thin branch of Picea abies that was still attached to the living tree. It was growing together with Sarea difformis. 

The spores are 4-celled and measure 18.4 - 23.5 × 5.6 - 6.6 µm. Asci bitunicate, no iodine reactions in Lugol's solution.

Any ideas what the species might be?

Re : Mytilinidion on Picea
Hello Juuso,
It seems to be very close to Mytilinidion tortile.
If you have enough material, I would be happy to study it.

Re : Mytilinidion on Picea
Thanks for the reply and offer! After some searching M. tortile was actually my best candidate, but the spores are a bit on the large side. I probably could send you the sample this week.

Re : Mytilinidion on Picea
Hi,

I know similar collections on resin and they might be somewhat close to Mytilinidion resinicola, although that species is described as having spores with constricted septa, which I have never clearly observed in my material. Some years ago I sent photos to Eric Boehm and he confirmed that M. resinicola might be the best name to use for these collections.
I am curious to hear your results, Alain.

Best wishes,
Gernot

Re : Mytilinidion on Picea
The sample is now posted, but it might take some time, since it's an economy letter. 

I found one key that stated that M. resinicola is a North American species, but who knows. The name sounds promising :).

Re : Mytilinidion on Picea
Hey everyone,

I know this species aswell, it is fairly common on blackened Picea abies resin, usually from higher altitudes. One collection from friend is on Abies alba. It can grow together with Lophium mytilinum, but that one is larger and more conchate.

I've got sequences from two cultures. In LSU there is about 4% (30nt) difference to either M. tortile, M.resinicola or Lophium arboricola. In spore morphology, there are clear and constant differences to these species.

In time we could put these collections together, if you would be interested.

bw,

Adam

Re : Mytilinidion on Picea
Good news !

My idea was indeed that it could be a new species. Indeed, not only the morphology and the size of the ascospores is different from the known species quoted, but also the morphology of the ascomata. Adam's answer confirms me. We can compare the results. I will contact you privately.
