Pertusaria paramerae A. Crespo & Vězda

Anal. Jard. Bot. Madrid, 41, 2: 252, 1985.

Synonyms:

Distribution: S - Bas.

Description: Thallus crustose, thinly episubstratic, white-grey or with a yellow-brown tinge, continuous to rimose-areolate. Apothecia numerous, crateriform, not constricted at base, immersed into 0.5-1.5 mm wide fertile warts, with an initially punctiform, later irregularly open, black disc covered with a thick, white pruina, and a prominent thalline margin. Epithecium yellowish green, K+ and N+ pink violet; hymenium and hypothecium colourless. Asci 2-spored, broadly cylindrical, the apex with a broad ocular chamber, the outer sheath K/I+ blue, otherwise K/I-, with an inner extensible layer, Pertusaria-type. Ascospores 1-celled, hyaline, ellipsoid, 120-190 x (40-)60-75(-90) µm, double-walled, the wall 5-8 µm thick, transversally striate. Photobiont chlorococcoid. Spot tests; thallus K+ pale yellow, C-, KC+ yellow orange P-. Chemistry: planaic acid (major), thiophaninic acid (trace), atranorin (trace), chloronorlichexanthone (trace), and an unidentified substance (trace,). Note: a species described from the Iberian Peninsula, where it mostly grows on Juniperus thurifera, and reported from Turkey; the only Italian station is in Basilicata.

Note: this species was described from the Iberian Peninsula, where it mostly grows on Juniperus thuriferain the supramediterranean belt, but also on J. phoenicea and J. oxycedrus in the eu-Mediterranean belt. According to Sipman (in litt.), who has studied the specimen, the earlier record of P. rhodiensis from Basilicata (see Nimis 1993: 519) refers to P. paramerae. The species, which is also known from Turkey, is chemically variable (see Halici & al. 2010).
