One to three genera, mostly crustose (Loxosporopsis dwarf-fruticose), with narrow hyaline spores, spirally arranged in the ascus. Typically with brownish-red pigmented lecanorine discs, with a distinctive K+ blue-violet reaction.
These are sister to Lecanoraceae, and I’m not 100% sure what separates them. None of these have Lecanora-type asci, and they have narrow fusiform, often multiply-septate spores, either twisted or spirally-arranged in the ascus.
There are only a handful of species in each (only one worldwide in Loxosporopsis).
|Ophioparma||spores straight, thollus uniformly K/I+ blue|
|Loxospora?||spores curved to twisted, thollus with broad axial body|
|Loxosporopsis?||spores curved to twisted, thollus with occular chamber but no axial body, dwarf fruticose|
