I have collected an Acarospora on wood on a bridge in Gijón (Asturias-Northern Spain). The hymenium is hemiamyloid and your thallus is C+ red, without bloom. Talo K-. Ellipsoidal spores of 4 x 1.5 microns.
Using the keys of the British Lichen Society, Vol. 12 "Acarosporales", by KNUDSEN & AL. (2021) have led me to Acarospora fuscata, a very common lichen on acid rocks, at least in England.
I would like to know the opinion of someone who has studied this type of lichens and if they should assess other epiphytic taxa and study other characters. Thank you so much.

Re : Acarospora fuscata
Hello Antonio
I've followed the Italic keys and these have led me to either A. similis or A. fusca, but both species are C- so I think my collections are diferent.
As for A. gallica, macroscopically they are the same, but the description speaks of blue or red I+ hymenium. It seems very ambiguous to me and the two sequences deposited in the Genbank are from China.
But it could be...
Thanks for your opinion.

Re : Acarospora fuscata
On old sun- exposed wood e.g. Quercus, some normally saxicolous lichens can be found, such as A fuscata, Candelariella vitellina, Protoparmeliopsis muralis, Lecidea fuscoatra, so dont wonder.
