Galapagos Species Database
The Galapagos Species Database shares the information about the species from our Natural History Collections.
Graphis intricata
liquen de escritura, Script lichen
Thallus thin, continuous to rimose, white to whitish gray, or creamy white; surface dull, not pruinose; Apothecia erumpent, lirellate; lirellae thin, elongate and moderately branched; labia thin, entire, shiny black, not covered by the thallus, but basally with lateral thallus hem; disc concealed, a thin slit; exciple completely carbonized, carbonization extending below the hymenium; hymenium hyaline, clear (not inspers), I–; ascospores hyaline, I+ bluish violet, 8 per ascus, ellipsoid to broadly fusiform, 20-28 x 6-8 µm, transversely septate, 5-8 celled. Chemistry: Norstictic acid; K+ orange-red (forming needle shaped crystals).
Galapagos specimens contain norstictic acid and thus belong to G. intricata, not G. subamylacea.
