Carbacanthographis tetrinspersa

Carbacanthographis tetrinspersa is a species of corticolous script lichen in the family Graphidaceae. Found in the primary rainforests of Mato Grosso, Brazil, C. tetrinspersa is named for its characteristic and inspersed hymenium.

Taxonomy

Described by the Dutch lichenologist André Aptroot in 2022, Carbacanthographis tetrinspersa is characterized by its distinctive with a and top, and its 3-septate . The species name tetrinspersa refers to the four- ascospores and the hymenium.

The thallus of Carbacanthographis tetrinspersa is crustose and continuous, closely adhering to the surface of the bark on which it grows. It has a dull, dirty white appearance and can cover areas up to in diameter, with a thickness of up to 0.1 mm. The is, a type of green algae.
Ascomata are, solitary, and superficial, with linear, wavy, and often branched. The is completely.
Chemically, the thallus tests negative in UV light, C, K, KC, and P spot test reactions but shows a positive reaction for K. Thin-layer chromatography reveals the presence of stictic acid, a compound relatively rare in the Graphidaceae but known in genus Carbacanthographis.

This lichen grows on tree bark in primary rainforests, with its known distribution limited to its type locality in Brazil.
