Sorry I don’t remember details of spores without looking it up. Might have a description at CNALH. “Verrucose perispore” refers to the texture on the coating on the outside of the outer wall of the spore. I struggle to see it in your photos.
Pannaria sphinctrina is a southern hemisphere species. I found in Research Gate the 1st page of the paper:
“Arve Elvebakk, The panaustral lichen Pannaria sphinctrina (Mont.) Tuck. and the related new species P. lobulifera from New Caledonia,Cryptogamie Mycologie 28(3):225-235, 2007.”
and from the abstract , I quote:
“Pannaria sphinctrina (Mont.) Tuck., is redefined as an exclusively panaustral lichen species, characterized by thin thallus lobes, ellipsoid, verrucose perispores and with vicanicin as its major secondary metabolite.”
I don’t exactly what is the meaning of “verrucose perispores”, but it is better to leave this specimen at the genus level.
I only find a link from Australia, but that doesn’t mean that the species is confined to the southern hemisphere.
The apothecia and the spores are very similar to those observed in a Fuscopannaria (see observation 236133), except for the extremities of the spores; However, The species in this genus have Nostoc as the alga and the photobiont observed is a green alga. Looking into the British Flora I learn that there is a group of Pannaria having a green photobiont, to which P. sphinctrina belongs.
Looking for images of this species I could only find to photos at the following Australian link
http://www.aucklandmuseum.com/...
where the 2nd photo could be a close-up of the first one and is very similar to my specimen, namely with the same type of apothecia and also with discontinuous thallus formed by small green lobes. I could not find a description of this species, but certainly is very close to mine.
According to Index Fungorum, the current name for Pannaria sphinctrina is Psoroma sphinctrinum.
I also remind the apothecia of some Fuscopannaria of the same kind. I’ll put it under the scope as soon as I can.
Thanks!
Pannariaceae family? Looks really interesting!
the photos of Psoroma hypnorum in CNALH.
However, the spores do not present two of the features mentioned there:
1) an apiculus at one or both ends, (this I found in Fuscopannaria ignobilis, see the thumbnail of observation 236133)
2) with prominent, warted-ridged epispore (as far as I understand, the epispores are like in some _Pertusaria spp., see e.g. the thumbnail of observation 358212, just to mention a recent one).
So, maybe this is yet another species.
Thanks for the help!
