Han & Baral, which is placed in the order Helotiales, contains non-operculate Discomycetes. Subiculum and septate spores are important morphological characters in this family. Subiculum refers to the protruding hyphal elements forming an interconnected network-like structure on the substratum surrounding the apothecia. This study focused on the micro and macro characters of Arachnoscypha aranea (De Not.) Boud. detected on decaying Pinus brutia L. branches near the dam lake in Bayramiç district, Çanakkale on 25 and 28 January 2025, and Arachnopeziza obtusipila Grelet detected on decaying branches of Quercus coccifera L.–Pinus brutia L. near Serçiler village. Macrofungal samples were identified as a result of meticulous field and laboratory studies. As a result of the data obtained, the macro- and micromorphological characteristics of the new genus record Arachnoscypha aranea and the new species record Arachnopeziza obtusipila were described and illustrated. In order to make the macrofungi described based on morphological characters clearer and more understandable, micromorphological features were drawn using CorelDRAW drawing software. The first record of the genus Arachnoscypha, which is represented by two species in the world, and the third species of the genus Arachnopeziza, which is represented by two species in our country, were given in this study, contributing to the mycobiota of Türkiye.}, number={2}, publisher={Ersin YÜCEL}
