Tricharia atrocarpa

Tricharia variratae is a species of foliicolous crustose lichen in the family Gomphillaceae that was described as a new species in 2005. The type was collected in Malaysia on Borneo, in Kinabalu Park at 1,800 m elevation, from leaves in May 1989. It is separated from other Tricharia species by its truly, black apothecia and its 3-septate ascospores.
The thallus forms pale greenish to whitish-grey crusts about 5–10 mm across, with a slightly irregular surface, and bears black, sterile 0.5–1 mm long. Its apothecia are numerous, rounded, and small, remaining black even when moist. They are strongly concave to almost urn-shaped, with the deeply submerged and a thin but strongly prominent margin. Microscopically, the is brownish-black and structureless, the is dark brownish-black, and the hymenium is colourless. The paraphyses are richly branched and interconnected, the asci are narrowly , and the ascospores are slightly constricted at the septa and measure 10–12 × 3–3.5 μm. were not observed. While most Tricharia species have paler, translucent apothecia, species with dark brown apothecia differ by having somewhat to muriform ascospores.
