Sphaerosporella ?

Microscopically the spores are globose 11-12µm in diameter (measured in asci as I could not find any free ones), asci are biseptate at base, IKI-ve, 180-210 x 16-20µm, paraphyses were septate, occasionally split at base and slightly inflated at the tips (about 7µm). There appear to be two types of hairs - dark brown, thick walled, septate and acute at the tip 180-330 x 21-27µm (which look like Scutellinia type hairs) and pale thin walled hairs.
I tried keying out these specimens but the only genus I could come close to is Sphaerosporella but they look different from S. brunnea and S. hinnulea and I am suspecting I got the genus wrong.
Any ideas?

Re : Sphaerosporella ?
I think that it is a Scutellinia... Why not? The hairs in Scutellinia are longer near the margin but they are present also towards the base. The pigments in the paraphyses are orange-reddish in water?

Re : Sphaerosporella ?
Hi there,
spores appear smooth because they are immature. Take another apothecia to check if there are mature spores, which will surely have a spiky / warty ornamentation (S. heterosphaera, S. legaliae, S. trechispora,...)

Re : Sphaerosporella ?
Thanks Björn for your suggestion. I will wait a few days and take a section from the larger specimen and see if it is mature enough.
