Lepraria lobificans Nyl.

Flora, 56: 196, 1873.
Synonyms: Lepraria santosii Argüello & A. Crespo
Distribution: N- TAA (Nascimbene & al. 2022). C - Laz (TSB 36478), Sar (Tretiach & al. 2009). S - Camp (Tretiach & al. 2009), Cal (CLU 12239), Si (Tretiach & al. 2009).
Description: Thallus leprose to subcrustose, generally well-delimited and forming regular, confluent rosettes, dirty white to pale grey with a bluish tinge, (0.16-)0.25-0.35(-0.47) mm thick, the margins distinct, usually well-developed, with a raised, thick margin. Cortex absent; hypothallus generally poorly developed, formed by light brown hyphae, K-; prothallus absent. Central part of thallus granular, tightly attached to the substratum, the granules ecorticate, soredia-like, ellipsoid to irregularly shaped, (0.22–)0.28-0.35(-0.65) mm in diam., devoid of crystals, surrounded by a weft of up to 100 µm long, hyaline, projecting hyphae; hypothallus compact, composed of tightly intertwined hyphae. Photobiont chlorococcoid, the cells 10-16 µm wide. Spot tests: K+ yellow-brownish, C-, KC-, P+ orange, UV- or UV+ pink. Chemistry: different chemotypes: 1) atranorin, roccellic acid, zeorin, stictic and constictic acids; 2) atranorin, UV+ vivid pink unknown, stictic and constictic acids; 3) atranorin, roccellic acid, stictic and constictic acids; 4) atranorin, roccellic acid, stictic and constictic acids, fumarprotocetraric or protocetraric acids; 5) atranorin. roccellic acid, protocetraric acid; 6) atranorin, roccellic acid, protocetraric acid, fumarprotocetraric acid; 7) atranorin, roccellic acid, fumarprotocetraric acid.
Note: on siliceous soil and on terricolous mosses, more rarely directly over siliceous rocks, in sheltered situations but in sunny and arid habitats, with optimum in the Mediterranean belt; probably more widespread in Southern Italy. For further details see Tretiach & al. (2009). The type of L. lobificans Nyl. proved to be identical with L. santosii, but the name was widely used to designate L. finkii (Lendemer 2013).
Growth form: Leprose
Substrata: soil, terricolous mosses, and plant debris
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
