Aspicilia contorta subsp. hoffmanniana S. Ekman & Fröberg
As Aspicilia contorta subsp. contorta but the areolas are flat, tighter against each other to the point of suggesting a single thallus, more angular and their surface is irregular and rugose. The apothecia are more prominent and less regular, and the discs are often distorted and concave. Same habitat as Aspicilia contorta subsp. contorta but in drier and sunnier areas. N.B. Can sometimes be confused with Aspicilia calcarea with which it can occur on limestone blocks (see pictures).This taxon, which we take in the sense of the British authors, is probably different from the taxa which were recently raised to the rank of species with two morphs:Aspicilia hoffmanniana morpho viridescens.
Calcareous saxicolous taxon with gray-greenish colorings coming on limestone rocks and concrete or cement in humid and little sunny areas.Aspicilia hoffmanniana morpho hoffmanniana.Calcareous saxicolous taxon with brownish colorings occurring on limestone rocks in dry and sunny areas.
