Шаблон:Short description Шаблон:Speciesbox

Bulbothrix cinerea is a species of lichenized fungi within the family Parmeliaceae.[1] Among other Bulbothrix species, only B. isidiza has isidia combined with an underside that is light coloured. B. isidizaШаблон:'s laciniae are wider, while its thallus is pale, and contains salazinic acid. In turn, B. ventricosa is larger and a black underside and rhizinae. The African species B. decurtata is an obligately saxicolous lichen, and while similar, it has a dark underside and produces salazinic acid in its medulla. The species' name thus refers to its uncommon dark gray colouration of its thallus.[1]

Description

Bulbothrix cinerea possesses a dark gray thallus and is saxicolous, measuring between Шаблон:Convert wide, being tightly adnate. Its laciniae measure between Шаблон:Convert wide, being shiny at the apex and laterally overlapping, also adnate. The species' ramification is irregularly dichotomous, with rounded apices, a crenate margin with a black line. It shows cilia that are between Шаблон:Convert long. Lacinules, soredia and pustulae are absent in this species.[1]

Its isidia are abundant, being laminal, cylindrical, irregular in diameter, and slightly inflated in shape. Its medulla is white, with a chestnut-dark brown coloured underside, being rugose, veined and papillate. The rhizinae are light brown, simple and bulbate, measuring between 0.1 and 0.5 mm long. Its apothecia are coronate, about Шаблон:Convert in diameter, while the amphithecia are isidiate. It counts with 8 spores per ascus, which are ellipsoid and measure between Шаблон:Convert long and Шаблон:Convert wide.[1]

Habitat

This saxicolous species finds itself tightly attached to its substrate and is frequently found on exposed quartzite rocks. It is known from Brazil, including the Espinhaço and Mantiqueira Mountains.[1][2]
