Özet:

 The occurrence of Armillaria mellea 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 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 p 0.109  0.05, z -1.603. The presenceabsence 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 1520C, 80 humidity and 8001000 m altitude. Our logistic regression analysis model z-9.5080.307xtemperature0.081xhumidity showed that if the temperature and humidity change by 1 unit in the region, sporocarp formation is affected by 36 and 8.4, respectively.

 Kocaeli, Yuvacık baraj havzası karışık-geniş yapraklı ormanlarında Armillaria mellea Vahl P. Kumm.nın oluşumu ve bu mantarın ekolojik özellikleri incelenmiştir. Araştırmalar sırasında, geniş yapraklı ormanların hâkim olduğu Yuvacık baraj havzasında küme örneklemesi ile seçilen parsellerde odunsu bitkiler üzerinde yetişen A. mellea sporokarpları fruktifikasyon organları analiz edilmiştir. Runs testi sonuçları, parsellerin seçiminde rastgelelik kurallarına uyulduğunu ve herhangi bir eğilimin olmadığını göstermektedir p 0.109  0.05, z -1.603. A. melleanın varlığıyokluğu ve çevresel değişkenler Ki-kare analizi ile test edilmiş ve sıcaklık bu çevresel değişkenler arasında farklılık göstermiştir. Dendrograma göre A. mellea daha çok çalışma alanının güneyinde görülmekte ve batı bakıyı tercih etmektedir. Bu makrofungusun çalışma alanın güneyini tercih etmesinin sebebinin ise yükseklik olduğu anlaşılmaktadır. Verilerimiz, A. mellea sporokarplarının genel olarak batı bakıda, 15-20 C, 80  nemde ve 800-1000 m yüksekliklerde bulunduğunu göstermektedir. Elde ettiğimiz lojistik regresyon analizi modeli z-9.5080.307xtemperature0.081xhumidity, bölgede sıcaklık ve nem 1 birim değişirse sporokarp oluşumunun sırasıyla 36 ve 8.4 oranında etkilendiğini göstermektedir.
