Alyxoria viridipruinosa is a species of corticolous (bark-dwelling) and lignicolous (wood-dwelling) lichen in the family Lecanographaceae. [2] It is found in Europe, where it grows on hardwood trees.

Taxonomy

The lichen was first formally described as a new species in 2011 by lichenologists Brian Coppins and Rebecca Yahr. The type specimen was collected from Needham Market ( Mid Suffolk, England), where it was found growing on the bark of Sambucus in a little-used, sheltered, chalk pit. The species epithet refers to the yellowish-green colour of the pruina visible on the discs and pycnidia. [3] Damien Ertz transferred the taxon to the genus Alyxoria in 2012. [4]

Description

The lichen has a thin, grey-green, powdery thallus. Its ascomata are in the form of lirellae that are evenly distributed throughout the thallus, and typically measure 0.3–0.6 mm long and 0.1–0.3 mm wide. The mostly-exposed disc is dark brown and covered with a green pruina that turns yellow after being dried. The ascospores, which measure eight per ascus, are hyaline, usually have 4 or 5 septa, and typically measure 15–19 by 4–5  μm. [3]

Habitat and distribution

In addition to England, Alyxoria viridipruinosa has also been recorded in Northern Ireland, Scotland, [3] Germany, [5] and the Netherlands. [6] It grows on a variety of hardwood trees, usually in secondary woodland, and often at forest edges. [3]
