Coelopogon is a genus of lichen-forming fungi in the family Parmeliaceae.[1] The genus contains two species found in southern South America and South Africa.

Taxonomy[]

Coelopogon was circumscribed in 1991 by lichenologists Franklin Andrej Brusse and Ingvar Kärnefelt, with assigned as the type species.[2]

Coelopogon was originally a segregate of genus Cetraria, and was grouped with the so-called "cetrarioid" lichens (lichens that are erect foliose form and have marginal apothecia and pycnidia).[3] Kärnefelt had in fact treated this genus under Coelocaulon,[4] a genus that is now considered to be synonymous with Cetraria.[5] DNA-based molecular phylogenetic analysis has shown, however, that there is no close relationship between the two genera.[6] Coelopogon does not align with any of the distinct clades that have been identified in the Parmeliaceae, and is grouped with the "genera of uncertain affinities".[3]

Description[]

Coelopogon has an erect fruticose growth form, it has medullary bundles of periclinal hyphae (i.e, parallel to the surface), and it lacks pseudocyphellae. Coelopogon species produce the secondary compounds 1 and 2. C. abraxas makes isidiate soralia, while C. epiphorellus makes clustered coralloid isidia, and soredia are absent.[2] Coelopogon abraxas also makes epiphorellic acid 3.[7]

Species[]

  • Brusse (1991) – South Africa; South America (Chile)[8]
  • (Nyl.) Brusse & Kärnefelt (1991) – South Africa; South America (Argentina, Chile, Falkland Islands); Antarctica[8]
