Observation 206104: Sphinctrina paramerae Muñiz & Hladun
When: 2015-06-06
Who: zaca
No herbarium specimen

Notes: The subject of this observation is the Lichenicolous fungus living on Pertusaria pertusa on the bark of an old Fraxinus tree. It is very similar to Sphinctrina tubiformis that I found before in some occasions (see observation 163571, observation 175667 and observation 188276): Apothecia more or less stalked, black, roundish, shiny.

Good job noticing this other species. … And it looks like there’s another paper in the Lichenologist from 1979 giving a key to the rest of the species of Sphinctrina in Eruope. I have access to that journal, would you like a copy?

When I saw the KOH reaction and the spores of this specimen I thought that this must be S. turbinata. However, the spores are a litle too big for that species. After some search I found mentioned a recently described species, S. paramerae, whose name cames from the common host (Pertusaria paramerae). I request the paper to their authors and one of them, Esteve Llop, send it to me; I’m grateful for his immediate response. After seeing the description of the species and the comparison with other Sphinctrina spp, I conclude that my specimen should belong to that species.

Microscopy added.
