Abstract

Hebeloma turleri doğada geniş yayılım gosteren ektomikorizal mantarlardır ve cok ceşitli habitatlarda yetişirler. Hebeloma turleri, turler arasındaki yuksek morfolojik benzerlik nedeniyle tanımlanması ve ayırt edilmesi zordur. Bu calışmada, Turkiye’den iki Hebeloma (Fr.) P. Kumm. turu (H. minus Bruchet ve H. rostratum Beker, Vesterh. & U. Eberh.) tanımlanmış ve fotoğraflanmıştır. Ornekler, molekuler ve morfolojik yontemler kullanılarak belirlenmiştir. İc transkripsiyon aralayıcı (ITS) ve translasyon uzatma faktoru 1-alfa (TEF1-α) bolgelerinin filogenisi Maksimum Olasılık yontemi kullanılarak oluşturulmuştur. Sonuc olarak, molekuler veriler ve morfolojinin birleşimi, Hebeloma turlerinin taksonomik durumunu değerlendirmek icin sağlam bir yaklaşım sunmuştur. Turlerin ayrıntılı acıklamaları ve cizimleri verilmiştir.

Identification and phylogenetic analysis of two newly recorded Hebeloma species (Basidiomycota) from Türkiye

Abstract

Hebeloma species are ectomycorrhizal fungi that are widely distributed in nature and grow in a wide variety of habitats. Hebeloma spp. are difficult to identify and distinguish due to high morphological similarity between species. In this study, two newly recorded Hebeloma (Fr.) P. Kumm. species (H. minus Bruchet and H. rostratum Beker, Vesterh. & U. Eberh.) from Türkiye were described and photographed. Specimens were identified using morphological and molecular methods. Phylogenies based on the internal transcribed spacer (ITS) and translation elongation factor 1-alpha (TEF1-α) regions of the genome were constructed employing the Maximum-Likelihood method. In conclusion, a technique that combines morphological and molecular data provides a robust approach to assessing the taxonomic status of Hebeloma spp. Descriptions and photographs of the species are also presented.
