New additions to Turkish Helotiales and Orbiliales

Aim of study: Though hundreds of studies were conducted on the biodiversity of Turkish fungi, the mycobiota has not been determined yet. Probably thousands of researches are required to determine the overall mycobiota of Turkey. This study were also carried out upon this purpose and aims to make a contribution to the mycobiota of Turkey by adding new genera and species records. Area of study: This study was carried out within the boundaries of ？slahiye, Nurda？？ and ？ehitkamil districts of Gaziantep province. Material and Methods: The macrofungi samples were collected from ？slahiye, Nurda？？ and ？ehitkamil districts in the years 2014 and 2015. After obtaining required field data, they were transferred to the fungarium and investigated in terms of macroscopy and microscopy. Then they were identified with the help of relevant literature. Main results: Five ascomycetous fungi species; Bisporella sulfurina (Quél.) S.E. Carp. (Helotiaceae Rehm), Lachnum fuscescens (Pers.) P. Karst. (Lachnaceae Raitv.), Cyclaneusma niveum (Pers.) DiCosmo, Peredo & Minter (Marthamycetaceae H.O. Baral, G. Lantz, Hustad & Minter), Hyalorbilia inflatula (P. Karst.) Baral & G. Marson and Orbilia aristata (Velen.) Velen. (Orbiliaceae Nannf.), within the orders Helotiales and Orbiliales were determined. Tracing the current literature the taxa were found to be new for the mycobiota of Turkey. Research highlights: Macrofungal biodiversity studies are necessary to be able to determine the mycobiota of Turkey
