Pyxine cocoes

Ciri dan struktur

Pyxine cocoes has a pale grayish-green thallus comprising radiating lobes that are typically less than 1 mm wide. These lobes are closely attached to the surface of the substrate, have granular soredia that protrude through the cortex in irregularly shaped regions called soralia. The medulla is white, while the apothecia are black with black margins in mature specimens. They are 1–5 mm wide, flat, and disc-shaped. The tissue making up the base of the apothecia is brownish red. Ascospores measure 15–22 by 6–8 μm. The lichen contains lichexanthone, a xanthone compound that is found in about 20 Pyxine species.

Habitat dan peran ekologis

Pyxine cocoes grows on bark and rocks. The lichen has been reported from Asia (Japan and the Philippines), East Africa, North America, Central America, and South America, Hawaii, and Australia. In Australia, it is present only in coastal locations that are seasonally humid, and both wet and warm. In this continent, it is common on tree trunks growing on coral cays; these trunks are often used as bird perches, which accumulate bird droppings. The lichenologist Roderick W. Rogers suggests that the lichen could be nitrophilic, which would explain this growth habitat, as well as its tendency to prefer habitats that are at least partially urbanized. In North America, it distribution extends as far north to Florida in the United States. The African species Pyxine katendei is somewhat similar in appearance to Pyxine cocoes, but it has only laminal (not marginal) soralia.
