Brief Description:

Order: Lecanorales
Suborder: Lecanorineae

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).

Genera:

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
