title: [Investigations of the problem of development of fluffy mycelium in cultivated mushrooms].
abstract: The study deals with the question of the influence of the nutrient medium upon appearance of a certain type of mycelium, namely the undesirable strongly fluffy type, which leads to decreased yields. The experiments were carried out with two strains of different color (each with fluffy and normal mycelium respectively). Six different nutrient media were tested. A lasting favorable influence of compost-agar was found, but only in the fluffy type of the white strain. The experiments also showed that it is possible to maintain fluffy and normal stringy types separately to some extent, by propagating only the desired type at each mycelium transfer.
