AB Two weakly differentiated taxa, Ganoderma lucidum and G. carnosum, were compared in their sufficient morphological and physiological features. The obtained results showed that dimensions of basidiospores and pileocystidia were insignificantly different, while pore shape and dimensions have shown greater diversity with average diameter of 138.46 μm in G. carnosum and 238.34 μm in G. lucidum. Mycelial growth rate was higher in G. lucidum (8.39 mm day−1) than in G. carnosum (6.02 mm day−1). G. lucidum was also a slightly better producer of biomass and extracellular polysaccharides (28.16 g L−1 and 1.42 mg mL−1, respectively) than G. carnosum (23.68 g L−1 and 0.35 mg mL−1, respectively). However, a higher amount of synthesized intracellular polysaccharides was noted in G. carnosum than in G. lucidum (40.00 mg g−1 and 30.00 mg g−1 of dry biomass, respectively). Higher activity levels of Mn-oxidizing peroxidases were obtained in G. carnosum, while G. lucidum was a better laccase producer. In G. carnosum, corn stem/NH4NO3 medium with nitrogen concentration of 20 mM was the optimum for Mn-dependent peroxidase production (88.00 U L−1), while the highest versatile peroxidase activity was detected in the medium with grapevine sawdust and 10 mM of nitrogen (80.80 U L−1). Wheat straw was the best carbon source for laccase synthesis in G. lucidum (55.75 U L−1).
