Bryocentria metzgeriae or B. hypothallina

Hello All,

I have found Bryocentria species on Metzgeria furcata a few times and am wondering what the main differences between the above species are.

The pictured species was found yesterday.

Perithecia orange, minute (cannot measure accurately <0.5mm), seem to have a few hairs. Asci 8-spored, 27.6 x 5.1. Ascospores 1-septate, ave. 8.9 x 3.5, hyaline. Stained with Iodine for clarity.

Any advice appreciated.

I have an idea but try microscopy with blue coton. The solution is in the centrum.

Re : Bryocentria metzgeriae or B. hypothallina
Thanks, Alain,

Does this help? Some spores seem to have cyanophilous warts showing in the Lactophenol Cotton Blue. Does this then probably make it B. hypothallina? I recently got a hold of the description that you co-authored and it seems to fit this species. Also, I noticed that the perithecia were forming on the ventral side of the thallus.

Thanks again.

Thanks. Looks like this could be the first UK record for this species.
