1921 A. L. Smith Lichens iii. 144 In lichens of foliose and fruticose structure, and in a few crustaceous forms, the soredia are massed together into the compact bodies called soralia.
1938 G. M. Smith Cryptogamic Bot. I. xiv. 518 They [sc. the soredia] may develop over the entire surface of a thallus or in localized pustule-like areas (soralia).
1970 Sci. Jrnl. Mar. 32/1 Many lichens have small powdery areas called soralia, the shape and location of which are characteristic for each species. The individual grains of powder in the soralia consist of an algal cell surrounded by fungal hyphae, and it is believed that they have a reproductive function.
1970 Sci. Jrnl. Mar. 32/1 Lichens which have abundant fungal fruit bodies rarely form soralia, and vice versa.
