Pyrenula cinnabarina

Pyrenula cinnabarina is a species of corticolous (bark-dwelling), crustose lichen in the family Pyrenulaceae. Found in Brazil, this species is notable for its dark carmine-red thallus and its known as ascomata (fruiting bodies), which are grouped in clusters of 5–30. The ascospores, which are the spores produced within the asci, are 3-septate, meaning they are divided into four sections, and measure 12–15 μm by 6–7 μm. The type specimen of Pyrenula cinnabarina was collected from Catimbau National Park in Buíque, Pernambuco, Brazil, at an elevation of about 880 m (2,890 ft). The thallus is thin, granular, and dark carmine red, lacking pseudocyphellae (small pores on the surface) and a prothallus (a border around the thallus). The ascomata are superficial (situated on the surface), globose (roughly spherical), 0.2–0.35 mm in diameter, and clustered in groups with fused walls but separate ostioles (openings). The walls of the ascomata are completely carbonised (blackened), and the ostiole......read more on Wikipedia.
