* Rinodina flavosoralifera Tønsberg (1992: 288) .

Characterized by a thallus composed of yellowish, sorediate areoles reacting C+ orange (arthothelin chemosyndrome) and the large Pachysporaria- type ascospores (up to 35.0 × 18.0 µm) which develop sporoblastidia ( Polyblastidium - type) ( Giralt et al. 2010). The species is known in Europe from Norway, Scotland, England and the Pyrenees ( France), in North America from Alaska and California and in Africa from the Canary Islands ( Giralt et al. 2010, Sheard 2010). The Guatemalan specimens possess better developed apothecia and ascospores than the previously recorded southernmost specimens from the Canary Islands and California.
