Abstract
Abstract A comparative study of the growth of eight species of ectomycorrhizal fungi [ Hebeloma edurum Metrod ex Bon, Lactarius deliciosus (L.: Fr.) S.F. Gray., Rhizopogon roseolus (Corda) Th.M.Fr., Suillus collinitus (Fr.) Kuntze, Suillus granulatus (L.: Fr.) Roussel, Suillus luteus (L.: Fr.) Roussel, Tricholoma focale (Fr.) Ricken, Tricholoma striatum (Schaeff.) Sacc.] in pure culture at different pH values, water potentials and temperatures was carried out. The biomass production and mycelial growth of each strain were assessed and characterised morphologically. H. edurum and L. deliciosus showed a clear affinity for neutral or slightly basic media. Most species had the lowest colony diameters and biomass production at pH 2.5. Only H. edurum, R. roseolus and S. collinitus grew at the highest water stress levels (−13.85 and −15.45 bar). All species grew at the lowest values of temperature whereas only R. roseolus and S. collinitus did at 30 °C.
