Table 3: Mycelium growth rates of 15 strains belonging to five mushroom species (P.cs: Pleurotus cystidiosus; P.er.: P. eryngii; P.os: P. ostreatus; P.pl: P. pulmonarius; A.cl: Agrocybe cylindracea) colonizing seven substrates (WS: wheat straw; TPOMW: raw two-phase olive mill waste; cTPOMW: composted two-phase olive mill waste) in “race-tube” experiments. Values (mm/day) are expressed as means ± standard errors of means, . Lack of letters in common indicates statistically significant differences (Gabriel's -test, ) for comparisons of treatment means between different strains (capital letters) and different substrates (lowercase letters).
