Pertusaria pseudocorallina (Lilj.) Arnold forma

Synonyms:

Family: PERTUSARIACEAE

Habitat: Aerohaline zone

Description

    This morph differs from the canonical type by its large isidia, mace-shaped and constricted at base, tips darker (to 2.5-3 mm tall), clustered in large heaps on the thallus. On very exposed rocks in capes and heads of extreme West of Brittany. N.B. Pertusaria coccodes that seldom grows on rocks has similar chemical spot tests (although KC+ yellow), but its isidia, also potentially heaps forming, are grey, smaller, its thallus is more greyish devoid of pink.*
