VARIATION OF MACROMYCETES SPECIES COMPOSITION IN TWO FOREST HABITATS FROM GIUMALAU MASSIF (EASTERN CARPATHIANS, ROMANIA)

摘要

Norway spruce ( Picea abies ) is the most common species with a large spreading in forests from Giumalau Massif. In this study the authors investigated the macromycetes species composition in two forest communities from Giumalau Massif: Hieracio transsilvanico-Piceetum and Leucanthemo waldsteinii-Fagetum. A total of 243 macromycetes species in 30 sampling areas have been identified. Changes in macromycetes species composition have been related to environmental factors (altitude) and vegetation (canopy cover, plant species diversity). The results suggest that variation in macromycetes species composition in the two forests types from Giumalau Massif is directly related to abiotic factors (altitude), woody species composition and plants communities’ structure.
