Candelariella rubrisoli

Candelariella rubrisoli is a sorediate, corticolous (bark-dwelling) crustose lichen in the family Candelariaceae. It was described in 2019 from Yunnan, China; the specific epithet refers to the red soils of the type locality. Subsequent work combining morphology with DNA sequence data has shown that C. rubrisoli is also widespread in Europe and that many European records previously using the name C. xanthostigmoides actually belong here. The species forms tiny yellow-green patches that break into powdery propagules called soredia (microscopic clumps of algal cells wrapped in fungal threads used for asexual dispersal). When fertile, its spore sacs (asci) usually contain eight spores, a point of difference from similar species with many-spored asci....read more on Wikipedia.
