Observation 368594: Arthoniales

When: 2019-04-15

Collection location: Sintra, Portugal [Click for map]

Who: zaca

No specimen available

Notes:
Growing on bark.
At first sight it looks like some Melaspilea, but the microscopy is somewhat different from that and I was not able to recognize even the genus of it.
The spores (only few observed) are submuriform with dimensions in the following ranges: 26.8 – 29.5 × 6.9 – 7.5 µm.
