Coniarthonia rosea is a species of lichen in the family Arthoniaceae.[1] Described from the Brazilian Amazon in 2014, this lichen has since been found in several states across northern Brazil, where it grows on smooth tree bark in primary lowland rainforests. The species is distinguished by its pale pink, irregularly shaped fruiting bodies that contrast with its thin dark-brown crusty growth, and by its unusually long, club-shaped ascospores. While closely related to other species in the genus Coniarthonia, it differs from the similar C. pulcherrima by its paler coloration, smaller fruiting structures, and distinct red pigment chemistry.
Coniarthonia rosea was described as new in 2014 by the lichenologists André Aptroot and Marcela Cáceres. The type was collected on smooth tree bark in primary rainforest at Cuniã Ecological Station in Rondônia (Brazil), at about 100 m (330 ft) elevation.[2]
The species belongs in Coniarthonia, a small genus characterised by hydrophobic, red-pigmented, margin-less apothecia and a crustose thallus. It grows with, but is consistently paler than, C. pulcherrima; its fruiting bodies (apothecia) are smaller and more irregular, and the pigment behaves as an anthraquinone rather than chiodectonic acid in tests, excluding the possibility that it is merely pigment-poor material of C. pulcherrima.[2] In a later molecular analysis of several Arthoniaceae species, C. rosea was shown to have a sister group relationship with C. pulchra.[3]
