Sphaerosporella ?
Carmel Sammut, 09-04-2015 21:39
I found these small specimens on ground near olive trees some days ago. The ascomata are very small about 1-2mm in diameter, perhaps immature. They appeared close to Scutellinia but the dark hairs are present all over the body.
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 Mario,
        Thank you for your reply. There is some colour in the paraphyses but it is located at the middle rather that at the tips.

I will taken another section and stain with cotton blue to check spore ornamentation but the spores appear smooth.

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,...)

regards,
björn

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.
