Observation 162939: Acarospora A. Massal.
When: 2014-03-15
Who: zaca
No herbarium specimen

Notes: Going back to the place of observation 128937 (and of observation 122470) the story repeats: another Acarospora growing on a Diploschistes sp. appears. This one, though vaguely similar to that of observation 128937, lacks the greenish tones on thallus being in this respect closer to Acarospora nodulosa (see observation 73080) though with some light yellow and grey tones, have a different chemistry from both.
