Abrothallus sp. sur Hypotrachyna britannica
Abrothallus sp.
sur
Hypotrachyna britannica
Synonyms:
Family: ABROTHALLACEAE
Habitat: Aerohaline zone
Description
Apothecoid "lens-like" ascomata as if placed on the thallus of the host, blackish disk but greenish if very fresh because covered with a dark green pruina.
Claved asci with 8 spores.
Brown ascospores, spinulose, with 2 cells including one larger, 11-12 x 4-5.5 µm.
Taxon coming on the lobes of
Hypotrachyna britannica
in the aerohaline zone.
This
Abrothallus
is characterized by its coming on
Hypotrachyna britannica
and its small spores 11-12 x 4-5.5 µm. It was not possible to name it because currently the morphological characters retained to characterize the different species of
Abrothallus
are too variable and crossed between the taxa and the specificity of the host is not proven... Moreover Paul DIEDERICH informs us (in litteris) that the usual genetic markers used for Ascomycetes do not allow to distinguish the species of
Abrothallus
on
Parmeliaceae
.
We therefore use sp.
while waiting for the use of new techniques.
