Lecanographaceae

Lecanographa is a genus of about 20 species of lichens in the family Lecanographaceae. These lichens typically form thin, extensive crusts that can be chalk-white, grey, or pale green, with dark brown to black reproductive structures that are often covered in a dense frosting () of white, bluish, or greyish crystals. Established as a genus in 1994 by José M. Egea and Pilar Torrente, the lichens are characterized by their partnership with orange-tinged filamentous algae and their production of slender, spindle-shaped spores with multiple cross-walls that are wrapped in a gelatinous outer layer.

Plectocarpon is a genus of lichenicolous (lichen-dwelling) fungi in the family Lecanographaceae. The genus, which was established in 1825 by the French botanist Antoine Laurent Apollinaire Fée, contains about 30 species that live as parasites on other lichens rather than forming their own independent body (thallus). These fungi are recognized by the small, wart-like swellings they create on their host lichens and by their distinctive dark fruiting bodies that often contain a green pigment that dissolves when treated with potassium hydroxide solution.

Alyxoria is a genus of lichen-forming fungi in the family Lecanographaceae. The genus has a cosmopolitan distribution. These lichens are often so inconspicuous that they appear as little more than faint cracks or weathered patches on tree bark and rock surfaces, making them easily overlooked in the field. The genus includes about 20 species that reproduce through distinctive elongated slits containing spores, and can also spread asexually through tiny flask-shaped structures that release microscopic propagules.

Zwackhia is a genus of crustose lichens in the family Lecanographaceae. It has six species. These lichens form thin, film-like crusts on bark and rock surfaces, often with a subtle orange tint from their algal partner. They produce distinctive elongated, slit-like fruiting bodies that remain narrow rather than opening into disc shapes.
