Observation 206104: Sphinctrina paramerae Muñiz & Hladun

When: 2015-06-06

Collection location: Serra de São Mamede, Portugal [Click for map]

Who: zaca

No specimen available

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.
