Abstract :The occurrence of Armillaria mellea insert ignore into journalissuearticles values(Vahl); P. Kumm. and the ecological characteristics of this fungus were studied in Kocaeli, Yuvacik dam basin mixed-broad leaved forests. During the surveys, we analyzed the sporocarps insert ignore into journalissuearticles values(fruiting bodies); of A. mellea growing up on woody plants in plots selected by cluster sampling in the Yuvacik dam watershed dominated by broad-leaved forests. The Runs test results showed that randomness rules complied in the selection of the plots, and there was no tendency insert ignore into journalissuearticles values(p= 0.109 > 0.05, z= -1.603);. The presence/absence of A. mellea and environmental variables were tested with Chi-square analysis, and the temperature differed among these environmental variables. To the dendrogram, A. mellea was mainly seen in the south of the study area and preferred western aspects. It is understood that this macrofungus prefers the south of the study area because of the altitude. Our data showed that sporocarps of A. mellea generally occurred in the western aspect, at temperatures of 15–20°C, >80% humidity and 800–1000 m altitude. Our logistic regression analysis model insert ignore into journalissuearticles values(z=-9.508+0.307xtemperature+0.081xhumidity); showed that if the temperature and humidity change by 1 unit in the region, sporocarp formation is affected by 36% and 8.4%, respectively.
