Growth inhibition for interacting species and interaction type for each combination of two strains (R, reference; S, saline) of three AH species—Heliscus lugdunensis (HELU), Tetracladium marchalianum (TEMA) and Flagellospora curta (FLCU) growing on MEA medium with (S, 6 g l−1 NaCl) or without added salt (R) (mean ± s.e.; n = 5). (n.a., not available).
