24 species of lignicolous macromycetes from 4 taxonomic families and 2 orders, Class Agaricomycetes, Phyllum Basidiomycota, have been analyzed. The cultural characters of these isolates had been observed, some of them being little studied till now. The dikaryotic mycelium from the trama of the sporoms was used for the isolation purpose. The fungal isolates were cultivated onto malt extract-agar media (malt extract 20g l-1) and incubated at 25 °C, in the dark, for 6 weeks. The cultures were observed directly and using a Nikon stereomicroscope in order to measure the growth rhythm and to observe the changes of the colonies: edge, surface, reverse, shape, colour, smell, presence or absence of the exudates. After 6 weeks from the inoculation, microscopic slides were made in order to investigate the types of hyphae, the colour and the structure of the mycelium and to note the presence of particular elements: cuticle, chlamydospors, arthrospores, conidia, and basidia. We noticed that the analyzed species present similar characters but also significant differences between them.
