Abstract On the site where the ground water table was during the year at the depth of 15 cm, I found on average 1,238 short mycorrhizal roots from 500 of soil samples, each of 500 g, about 70 % fragments were from living roots. There were four sub-subtypes: Aa, Ac, Bd and Cf and three subtypes of ecotrophic mycorrhizas: A, B and C. About 70.3 % was A subtype, 17.6 % of C and 7.1 % of B subtype. On the other stand where the ground water table was at 50 cm, there was a rich mycorrhizal spectrum. In the soil samples were on average 2,769 short mycorrhizal roots per sample; about 85 % were from living roots. I described there 11 mycorrhizal sub-subtypes: Aa, Ac, Ba, Bd, Ca, Cd, Cf, Fd, Fg, Ga and Ia. In samples were 65 % of A subtype, 3.2 % of B subtype, 9.8 % of C subtype, 4.2 % of F subtype, 15.0 % G subtype (Cenococcum graniforme) and 2.7 % of I subtype. No significant differences were found in the mycorrhizal subtype variety between young seedlings and older trees. The richest mycorrhizal association were found down to depth 10 to 15 cm. There were approximately 253 kg/ha of mycorrhizal fragments in the first stand and 464 kg/ha of mycorrhizas in the 15 cm surface soil layer in the sedond stand.
