Melaspilea bagliettoana?
Gernot Friebes, 13-05-2025 12:32
Hi,

I found this one on a Picea abies branch. It looks like it might be Melaspilea bagliettoana, or at least close to it. The ascospores are < 15 µm in length. I'd appreciate your opinion on it.

Best wishes,
Gernot

Re : Melaspilea bagliettoana?
Hallo,

have you seen/measured also (over)mature ascospores that should be getting brown. They would be expectingly longer and could direct you to Melaspile(ell)a proximella. I collected some specimens from Abies/Pinus mugo branches as well as bark of Picea that are sometimes on the lower spore limit for M. proximella but I filed them arbitrarily under M. proximella because M. bagliettoana is presented as a species of (nutrient-richer) bark of deciduous trees like Fraxinus or Populus tremula

Hi Gernot,

what else? The other species in question with spores having bipolar setae, Melaspileella proximella, has larger spores with more(?) setae: https://italic.units.it/index.php?procedure=taxonpage&num=2647

Re : Melaspilea bagliettoana?
Thank you, Zdenek and Martin.
I did not see any overmature ascospores.
I excluded M. proximella mostly because of the ascomata which are lirelliform hysterothecia in my material, quite different from typical M. proximella as far as I am aware.
On the other hand, I have not found any records of M. bagliettoana on coniferous wood. But maybe it does switch hosts occasionally...

Best wishes,
Gernot

Re : Melaspilea bagliettoana?
I missed that, thank you. In that case I think M. bagliettoana is a reasonable name for this collection.

Best wishes,
