Hello.A tiny fungus shaped like globose black grai
Récolte réalisé sur Rhytidiadelphus (Pessière sur tourbe à 1'017 m), apothécies 0.15 - 0.5 mm de diamètre, blanc, stipitée, asques 60 - 75 x 6 - 8 µm, avec crochets, octosporés, IKI-, IKI/KOH+, spores 4.5 - 6 x 3 - 4 µm, finement verrruqueuse, hyalines, paraphyses non renflées au sommet, garnies de petites guttules. Merci d'avance.

Thanks. I realised some errors in my drawing so will fix before re-posting here. The apothecia in this case were up to approx 0.5mm, not up to 1.5. I also examined another apothecium to try see the hair cells better.
Regarding possible ornamentation, in some empty spores the possible puncta seemed more obvious. When I have access to my Leitz again from tomorrow I will try to visualise them better. Perhaps they were an artefact. Certainly difficult to resolve and not consistent.
I agree with B. rhombisporus. I originally did not realize that the Muscicola / Pithyella one with lemon-shaped spores was different to what you call B. rhombisporus. I think croziers were present but I will check again.
It will be good to compare the sequences, and also with the two Pithyella spp. I hope to sequence as well.
I will update this info in a separate forum post soon.
Thanks and all the best,
George
