Türkiye'deki bazı Acarospora (Acarosporales, Ascomycota) türleri üzerinde moleküler ve taksonomik çalışmalar

Acarospora, Acarosporaceae familyasında yer alan kabuksu bir liken cinsi olup, dünya üzerinde geniş bir yayılış alanına sahiptir. Acarospora cinsi içerisinde dünyada 200'den fazla tür bulunurken, Türkiye'de şu ana kadar tespit edilen tür sayısı 41'dir. Bu çalışma, Türkiye liken florası için üç likenleşmiş mantar ve iki likenikol mantar türü yeni kayıt olarak sunulmaktadır: Acarospora irregularis H. Magn., Acarospora rosulata (Th. Fr.) H. Magn., Acarospora thamnina (Tuck.) Herre, Lichenostigma svandae Vondrák & Šoun, Stigmidium fuscatae (Arnold) R. Sant. Bu 5 takson hakkında detaylı bilgiler fotoğraflarla birlikte verilmektedir. Yeni kayıtların nrITS, β tubulin ve mtSSU gen bölgeleri çalışılmış ve türlerin filogenetik konumu Acarospora cinsinde yer almış ve cinsin diğer türlerinden net olarak ayrılmıştır.

Molecular and taxonomic studies on some Acarospora (Acarosporales, Ascomycota) species in Türkiye

Acarospora is a crustose lichen genus in the family Acarosporaceae and has a wide distribution. While the lichen genus Acarospora has more than 200 species in the world, the number of species so far determined in Türkiye is 41. Here we report three Acarospora species: A. irregularis H. Magn., A. rosulata (Th. Fr.) H. Magn., A. thamnina (Tuck.) Herre and two lichenicolous fungal species: Lichenostigma svandae Vondrák & Šoun, Stigmidium fuscatae (Arnold) R. Sant. new to Türkiye. Detailed information on these 5 taxa is provided along with photographs. The nrITS, β tubulin and mtSSU gene regions of the new Acarospora records are studied and their phylogenetical positions are discussed.

Keywords:
