Observation 92589: Pyrrhospora quernea (Dickson) Körber
When: 2012-04-06
Who: zaca
No herbarium specimen

Notes: Growing on the bark of a Quercus suber. These specimens are similar to the one in MO91477, but without the withish prothallus of that one. Thanks to Jason comments in that observation, it seems that these specimenns may be Pyrrhospora quernea, as they react with C+ orange, K-, KC+ orange to red. Some good photos of this species can be seen in Stridvall.

I think you’re right

It is significant that the soredia cover the entire surface, I think. Many sterile crusts have discrete, delimited soralia.
