Karst.) H.L. Chamb. Türkiye’den ilk defa ve familya düzeyinde rapor edilmiştir. Türün kısa deskripsiyonu ve makro ve mikromorfolojilerine ait fotoğraflarları verilerek kısaca tartışılmıştır. Anahtar kelimeler: Hypocrea leucopus, Ascomycota, Yeni kayıt, Türkiye 1. Introduction The family Hypocreaceae is classified in the Ascomycota division, Sordariomycetes class and Hypocreales order. Members of Hypocreaceae are usually recognized by their brightly colored, perithecial ascomata and globose, ellipsoid to cylindrical ascospores. The family includes 22 genera and 454 species. (De Notaris, 1844; Kirk et al., 2008). Hypocrea Fr., the type genus of Hypocreaceae is generally characterized by the presence of perithecia embedded in fleshy stromata, which is formed by pseudoparenchymatous tissue or highly compacted hyphae. The genera include 75 species, all of which are recognized in Europe (Jaklitsch, 2011). Stipiate species of Hypocrea are characterized especially by the presence of pale to brightly colored, erect, clavate to cylindrical stroma; they have been segregated as genera Podostroma P. Karst. Podostroma differs from Hypocrea on the basis of presence of gross morphology of the ascomata. The type species of Podostroma is P. leucopus P. Karst. ; its former synonym was P. alutaceum (Pers.) G.F. Atk. Extensive studies on the type and existing specimens of these two species lead the researchers to distinguish them from each other in terms of morphological and biological characteristics (Chamberlain et al., 2004; Jaklitsch, 2011). According to current checklists (Solak et al., 2007; Sesli and Denchev, 2008) and the recent contributions on Turkish macromycota (Akata and Doğan, 2011; Akata et al., 2011; Akata et al., 2012; Akata and Kaya 2012a, b; Akgul et al., 2011; Allı, 2011; Allı et al., 2011; Castellano and Türkoğlu, 2012; Doğan and Aktaş, 2010; Doğan et al., 2011, 2012; Dülger and Dülger, 2010; Gücin et al., 2010; Türkekul and Zülfükaroğlu, 2010; Uzun et al., 2010), there isn’t any record from Turkey, related to members of Hypocreaceae. The present study aims to make a contribution to Turkish mycobiota. * Corresponding author / Haberleşmeden sorumlu yazar: Tel.: +903122126720/1066; Fax: +903122232395; E-mail: e-mail: fungus@hotmail.com.tr © 2008 All rights reserved / Tüm hakları saklıdır BioDiCon. 242-0412 38 Biological Diversity and Conservation – 5 / 3 (2012) 2. Materials and methods Specimens were collected from Uzungöl Nature Park (Trabzon) in 2011. Relevant morphological and ecological characteristics of the samples were noted and they were photographed in their natural habitats before taken to the herbarium. Microstructural data was obtained by light microscopy after treating the samples with the reagents such as distillate water, Melzer’s reagent, 5% KOH, congo red, cotton blue etc. Microphotographs of asci and ascospores were taken by Leica DM 1000. Identification was performed with the aid of related literature (Chamberlain et al., 2004; Jaklitsch, 2011). The identified specimens were deposited at Ankara University Herbarium (ANK). 3. Results A short description, geographical position, locality, collection date, ecology and distribution, photographs of fruit bodies and microphotographs of asci and ascospores of the species are provided. The systematic of the taxon is according to mycobank (URL1: http://www.mycobank.org: accessed: 20 March 2012). Fungi Ascomycota R.H. Whittaker Pezizomycotina O.E. Erikss. & Winka Sordariomycetes O.E.

(1892) Macroscopic and microscopic features: Stromata separated into fertile and sterile parts. Total stroma 30-45 mm tall, clavate, straight or more commonly curved, Fertile part 10-15 mm, yellow to golden brown, hollow, surface, smooth, glabrous, slightly tuberculate, somewhat rugose, when fresh ostiolar dots visible slightly darker than background. Stipe cylindrical, sterile, white to beige. Flesh firm, white and odourless. The upper part covered by white to yellowish, straight to curved, smooth or slightly longitudinally furrowed perithecia (Figure 1a). Asci 75-85 x 4-5 µm cylindrical, 16 spored, uniseriate (Figure 1b). No paraphyses were seen. Ascospores 3-4 x 2.5-3.5 µm, hyaline, wedgeshaped or subglobose, usually distinctly flattened on one side (Figure 1c). Ecology: Autumn, on ground among litters, typically in mixed forest (Chamberlain et al., 2004). Distribution: Europe and North America (Chamberlain et al., 2004; Jaklitsch, 2011). Specimen examined: TURKEY—Trabzon: Çaykara, Uzungöl Nature Park: In Picea orientalis L. and Fagus orientalis Lipsky mixed forest, on soil, among needle litters, 40° 37' N - 40° 19' E, 1510 m, 09.10.2010, Akata 3298. Figure1. Hypocrea leucopus: a- stromata, b- asci, c- ascospores 4. Discussion Hypocrea leucopus is macroscopically very close to several stipitate Hypocrea species (H. alutacea (Pers.) Ces. & De Not., H. nybergiana T. Ulvinen & H.L. Chamb. and H. seppoi Jaklitsch) because of their similar macromorphology. H. alutacea forms clavate to irregular, often laterally fused stromata on wood or bark of deciduous trees, but Hypocrea leucopus occurs on the ground in forests, typically in mixed forests. H. nybergiana differs from H. leucopus by the presence of larger, reddish brown stromata (46-93 mm) and slightly larger ascospores (3–5.5 x 3–4.2 μm). Stroma of H.seppoi shares the same colour with Hypocrea leucopus but it is smaller (up to 25 mm) (Chamberlain et al., 2004; Jaklitsch et al, 2008; Jaklitsch, 2011).
