INTRODUCTION Though the systematic position of the genus still Wakefieldia Corner & Hawker is a hypogeous remains in dispute, here we follow Kirk et al. (2008) basidiomycete genus in the family Boletaceae (Kirk et and Index fungorum (accessed on 20 May 2019) and al., 2008). The genus contains two species and regard it in Boletaceae. characterized by globose to irregular gasterocarp, thin, Only one hypogeous member of Boletaceae within the whitish and smooth peridium; minute and crowded genus Octaviania Vittad. has been reported from chambered loculate gleba, statismosporic, orthotropic, Turkey (Türkoğlu et al., 2015; Kaygusuz et al., 2018). globular spores ornamented with broad verrucae or Current checklists on Turkish macromycota (Solak et irregular ridges (Pegler et al., 1993). al. 2015; Sesli and Denchev 2014) and the Genus Wakefieldia was erected by Corner and Hawker contributions published after the checklists (1953) based on the description of Wakefieldia (Sadullahoğlu and Demirel, 2018; Uzun et al., 2018; striaespora Corner and Hawker, and Hawker (1954) Acar et al., 2019; Keleş, 2019; Uzun and Kaya, 2019a,b; assigned the genus to Hydnangiaceae. Later on Pegler Yakar et al., 2019) indicate that Wakefieldia & Young (1979) proposed to move it to Octavianinaceae macrospora (Hawker) Hawker hasn’t so far been (Krakhmalnyi et al., 2014). Kirk et al. (2008) lists this reported from Turkey. The study aims to contribute to genus in Boletaceae. The ITS and nuc-LSU sequence the Turkish mycobiota. based data gathered by Kaounas et al.

Photographs of fruit bodies were taken in their Macroscopic and microscopic features: Basidiomata natural habitats and characteristics related (0.8-)10-20 mm in diam, gasterocarpic, hypogeous, morphology and ecology were noted.

Though it was first collected under beech (Hawker, 1954), and Watling (2008) proposed Statement of Conflict of Interest that it could be mycorrhizal with beech, Kaounas et al. Authors have declared no conflict of interest. (2011) mentions about the probable association with oaks, based on four Greek collections. Turkish Author’s Contributions specimens of W. macrospora were also collected under Quercus L. sp. The contribution of the authors is equal. The macro and micromorphological features of Turkish specimens of W. macrospora are in agreement with REFERENCES those given in literature (Hawker, 1954; Montecchi Acar İ, Uzun Y, Keleş A, Dizkırıcı Tekpınar A. 2019. and Sarasini, 2000; Pegler et al., 1993; Calonge et al., Suillellus amygdalinus, a new species record for 2003; Kaounas et al., 2011; Krakhmalnyi et al., 2014).
