Özet:

 Bryophyta members in the subkingdom Bryobiotina are distributed in a wide variety of habitats. Mosses are morphologically divided into two large groups: acrocarpous and pleurocarpous. Acrocarpic species have arid character and pleurocarpic species are distributed in more moist regions. The spores of the pleurocarpous Brachythecium salebrosum Hoffm. ex F. Weber  D. Mohr Schimp. and the acrocarpous Crossidium squamiferum var. pottioideum De Not. Mönk. were examined in comparison in this study. Spore slides were prepared using both Erdtman acetolysis and Wodehouse methods and examined under a light microscope LM. As a result of the analyses, it was found that the spores of C. squamiferum var. pottioideum were oblate in both methods, while the spores of B. salebrosum were suboblate in the acetolysis method and oblate in the Wodehouse method. Spores of both taxa are classified as small spores. Furthermore, the equatorial axis is longer than the polar axis in the spores of both taxa and the thicknesses of the intine layer of the spores are almost identical at 0.50 µm B. salebrosum and 0.53 µm C. squamiferum var. pottioideum. In addition, the thickness of the sclerine of B. salebrosum spores was about 0.70 µm in both methods, while it was 0.56 µm in acetolysed spores of C. squamiferum var. pottioideum and 0.78 µm in Wodehouse treated spores. Both taxa have monolete and trilete spores. On the other hand, SEM examinations revealed that B. salebrosum has gemmate ornamentation, while C. squamiferum var. pottioideum has verrucate ornamentation. The findings obtained as a result of the studies helped to reveal the differences between the spores of taxa in different morphological groups and brought a different perspective in their ecological evaluation.

 Bryobiotina alt alemindeki Bryophyta üyeleri çok çeşitli habitatlarda dağılım gösterir. Karayosunları morfolojik olarak iki büyük gruba ayrılır: akrokarp ve pleurokarp. Akrokarpik türler kurak karaktere sahipken, pleurokarpik türler daha nemli bölgelerde yayılış gösterir. Bu çalışmada pleurokarp Brachythecium salebrosum Hoffm. ex F. Weber  D. Mohr Schimp. ve akrokarp Crossidium squamiferum var. pottioideum De Not. Mönk. sporları karşılaştırmalı olarak incelenmiştir. Spor preparatları hem Erdtman asetoliz hem de Wodehouse yöntemleri kullanılarak hazırlanmış ve ışık mikroskobu IM altında incelenmiştir. Analizler sonucunda, C. squamiferum var. pottioideum sporlarının her iki yöntemde de oblat olduğu, B. salebrosum sporlarının ise asetoliz yönteminde suboblat, Wodehouse yönteminde ise oblat olduğu tespit edilmiştir. Her iki taksonun sporları da küçük sporlar olarak sınıflandırılır. Ayrıca, her iki taksonun sporlarında ekvatoral eksen polar eksenden daha uzundur ve sporların intin tabakasının kalınlıkları 0,50 µm B. salebrosum ve 0,53 µm C. squamiferum var. pottioideum ile neredeyse aynıdır. Buna ek olarak, B. salebrosum sporlarının sklerin kalınlığı her iki yöntemde de yaklaşık 0,70 µm iken, C. squamiferum var. pottioideumun asetolize sporlarında 0,56 µm ve Wodehouse yöntemi uygulanmış sporlarda ise 0,78 µmdir. Her iki takson da monolet ve trilet sporlara sahiptir. Diğer yandan, SEM incelemeleri B. salebrosumun gemmat ornamentasyona sahip olduğunu, C. squamiferum var. pottioideumun ise verrukat ornamentasyona sahip olduğunu ortaya koymuştur. Çalışmalar sonucunda elde edilen bulgular, farklı morfolojik gruplarda yer alan taksonların sporları arasındaki farklılıkların ortaya konmasına yardımcı olmuş ve ekolojik değerlendirmelerinde farklı bir bakış açısı getirmiştir.
