The Arthoniales are an order of the ashes . They are lichen builders or live as saprobionts on plants. The mostly crust-like lichens they form with green algae .
features
They usually form apothecia . Sometimes these are also closed and then have an elongated, pore-shaped opening. The peridia is thick or thin-walled. The intermediate asci tissue consists of branched paraphyses in a gel-like matrix. The asci are thick-walled and turn bluish with iodine. The ascospores are aseptate or septate, sometimes brown.
Systematics
The Arthoniales were for a long time the only order of the class of Arthoniomycetes with four families, some of them very generic, and some genera of uncertain allocation. In 2014 the order of the Lichenostigmatales was described and recognized as a sister order of the Arthoniales, so that the class of Arthoniomycetes is no longer monotypical . At the moment (as of October 2018) seven families belong to the order with several genera of uncertain position:
- Andreiomycetaceae with the only genus Andreiomyces
- Arthoniaceae : species-rich family with 21 genera
- Chrysotrichaceae
- Lecanographaceae
- Opegraphaceae
-
Roccellaceae : with 40 genera
- Ancistrosporella
- Austrographa
- Austroroccella
- Chiodecton
- Crocellina
- Dendrographa
- Dichosporidium
- Dirina
- Diromma
- Enterodictyon
- Enterographa
- Erythrodecton
