DE1669696553A37DFF6EF9E8FCC07202.taxon	description	The species has a squamulose to minutely foliose thallus composed of pale chestnut-brown to gray-brown lobes, forming a rosette. It tightly adheres to its substrate with distinct peripheral lobes and its upper surface is fragile (Fig. 4). When wet, the thallus turns dark blue-gray. The thallus is sorediate with dark gray, coarsely granular soredia formed in predominantly marginal, sometimes also laminar, button-shaped soralia. These soralia are initially concolorous with the thallus surface, their soredia sometimes brittle, on a ± uniform surface, which may become coarsely cracked along the margin. The thallus resides on an arachnoid hypothallus, blue-black in color. In the specimens collected in Algeria, apothecia were not observed; the photobiont is Nostoc.	en	Belguidoum, Amina, Lograda, Takia, Ramdani, Messaoud (2022): The Lichen Flora on Quercus in the Tamentout Forest of Algeria.

DE1669696553A37DFF6EF9E8FCC07202.taxon	discussion	Notes: Only a single corticolous specimen of Parmeliella testacea was found in the Tamentout Forest, growing on Q. suber. The species generally appears to be quite rare, and in France its threat status has been assessed according to IUCN red-list criteria as Vulnerable (VU) by Roux et al. (2017). In the past, the species had been reported from England, but it is considered extinct (Cannon et al. 2021).	en	Belguidoum, Amina, Lograda, Takia, Ramdani, Messaoud (2022): The Lichen Flora on Quercus in the Tamentout Forest of Algeria.
