Martinjahnsia is a single-species fungal
genus in the family
Teloschistaceae .
[2] It contains the sole species Martinjahnsia resendei , a
saxicolous (rock-dwelling)
crustose lichen .
Taxonomy
This species was first
scientifically described in 1968 by
Josef Poelt and
Carlos das Neves Tavares , who initially classified it in the genus
Xanthoria .
[3] In 2003,
Sergey Kondratyuk and
Ingvar Kärnefelt proposed to transfer the species to the genus
Rusavskia .
[4] Kondratyuk and colleagues suggested in 2012 that it be placed in a new genus, Martinjahnsia , to accommodate its unique
phylogenetic position. The genus name honours German lichenologist
Martin Jahns .
[5]
Habitat and distribution
Martinjahnsia resendei has a
Mediterranean distribution. The lichen is abundant in the southeast of Spain, where it
colonises sunny rock surfaces, especially those enriched in
nitrates .
[6] In islands of the
Tuscan Archipelago , it is typically found on sun-exposed
siliceous rocks on the Mediterranean coast.
[7]
Chemistry
There are several
lichen products that have been isolated and chemically characterised from Martinjahnsia resendei . These include
peroxyergosterol , the
anthraquinone pigments
physcion ,
fallacinal , and
fallacinol , and three new unidentified
hopene -type
triterpenes .
