''Enterographa kinabaluensis'' is a species of
corticolous (bark-dwelling)
crustose lichen in the family
Ramalinaceae.
Found in coastal rainforests on the island of
Borneo, it was described as a new species in 2020. Characterised by its white
thallus, (dot-like)
soralia
Soredia are common reproductive structures of lichens. Lichens reproduce asexually by employing simple fragmentation and production of soredia and isidia. Soredia are powdery propagules composed of fungal hyphae wrapped around cyanobacteria o ...

Although the presence of
ascomata on the
soredia might initially suggest a
parasitic relationship, this was ruled out by the authors because of the identical chemistry of both the thallus and the ascomatal margin.
