Canoparmelia roseoreagens is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae.[1]
Taxonomy
Found in Brazil, it was formally described as a new species in 2009 by the lichenologists Marcelo Marcelli, Luciana da Silva Canêz, and John Elix. The type specimen was collected from a Brazilian pine forest in Fazenda da Estrela (Vacaria, Rio Grande do Sul) at an elevation of 905 m (2,969 ft), where it was found growing on tree bark.[2]
Description
This lichen has a greyish appearance and is sublaciniate, meaning it has irregularly branched [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] that are adnate (attached) and contiguous (touching), with truncate apices and a smooth to [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] margin. The upper surface is smooth and may have weak or absent [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], which are reticulate (net-like), more evident in the young parts and may form small cracks. There are no [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] or soredia. The isidia are the same colour as the thallus, cylindrical, and erect, ranging from simple to mostly [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], brown, and measuring 0.10–0.45 mm wide.
The medulla is white and does not produce a purple pigment when treated with K. The lower surface is black to dark brown, slightly shiny, and rugose (wrinkled); the marginal zone is brown, shiny, and rugose (or sometimes [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]); the rhizines (root-like structures) are white, dark brown, or rarely black, simple to furcate (forked), 0.25–0.50 mm long, few to frequent, and almost evenly distributed. There are no apothecia (cup-like sexual reproductive structures) or pycnidia (small asexual reproductive structures).[2]
Canoparmelia roseoreagens contains several major lichen products: methyl olivetolcarboxylate, methyl divarinolcarboxylate, and eight unknown depsides that are derivatives of norsekikaic acid, norhomosekikaic acid, and norhyperhomosekikaic acids. The species epithet roseoreagens refers to the C+ (rose) chemical spot test reaction observed on the medulla.[2]
Habitat and distribution
Originally described from specimens collected in the Fazenda da Estrela in Northern Brazil, this corticolous (bark-dwelling) species has since been recorded from São Maurício (Braço do Norte, Santa Catarina) in Southern Brazil.[3]
