Abstract (2. Language): 
Aquatic hyphomycetes flora of decaying leaves fallen to Aras River and its branches within province boundary of Erzurum was investigated. Twelve sampling station were selected on the river and its branches as eight for leaf samples. From these stations total 83 leaf samples were collected. By using "Incubation in Petri Dish" and "Aerated Incubation in Flask" methods, 21 different taxa belonging to 12 genera of aquatic hypho-mycetes fungi were obtained from these samples. Incubation temperatures were chosen as "ambient tempera-ture (22-26°C)" and "12°C". The most common species encountered were Tetracladium marchalianum and Ar-ticulospora proliferata. In addition, the next common taxa were Lemonniera aquatica, Alatospora sp., Alato-spora acuminata, Anguillospora longissima, Clavariopsis aquatica, Clavatospora longibrachiata on leaf sam-ples respectively. The taxa obtained from the study were generally cosmopolitan or ones which found cold and temperate climates. Except pH, there was not any meaning relation between chemical properties of water and distribution of the taxa to months. It may say that there is a decrease in species richness with increased pH.

Abstract (Original Language): 
Erzurum ili idarî sınırları içerisinde kalan Aras Nehri ve kolları içerisinde çürümeye yüz tutmuş yaprak örneklerindeki akuatik hyphomycetes florası bu çalışmanın araştırma konusudur. Araştırma alanında ağaçlardan veya bodur çalılardan dökülen yaprakların birikim gösterdiği 8 istasyondan alınan toplam 83 yaprak örneğine "Petri Kabında İnkubasyon" ve "Beherde Havalandırmalı İnkubasyon" metotları uygulanarak 12 cins ve bu cinslere ait 21 farklı akuatik hyphomycetes taksonu elde edilmiştir. İnkubasyon sıcaklığı olarak oda sıcaklığı (22-26°C) ve 12°C kullanılmıştır. Araştırmada rastlanan en yaygın türler Tetracladium marchalianum ve Articulospora proliferata’dır. Yaprak örneklerinde bunlardan başka diğer yaygın taksonlar, sırasıyla Lemonniera aquatica, Alatospora sp., Alatospora acuminata, Anguillospora longissima, Clavariopsis aquatica ve Clavatospora longibrachiata’dır. Elde edilen taksonlar genellikle kozmopolit veya soğuk ve ılıman iklim-lerde yaygın olan cins ve türlerdir. pH hariç suyun kimyasal özellikleriyle elde edilen taksonların aylara dağılı-mı arasında bir ilişki bulunamamıştır. Ancak pH’nın yükselmesi ile tür zenginliğinde bir azalma olduğu söyle-nebilir.
