text: # Tapellaria isidiata
  
  Tapellaria isidiata is a species of corticolous lichen in the family Lecanoraceae. Found in Cameroon, it was described as a new species in 2021 by lichenologists Klaus Kalb and André Aptroot. The type was collected from Campo (South Province), where it was found growing on tree bark on a beach. The lichen has a glossy, mineral-grey thallus with whitish patches, and is bordered by a black hypothallus measuring 0.2–0.6 mm wide. The specific epithet isidiata refers to the presence of isidia, a characteristic of this species: it is the first in genus Tapellaria to have vegetative propagules. The lichen is unreactive to standard chemical spot tests.
