    Amanita vidua: A new record for Turkish Amanita Section Phalloideae based on morphological and molecular data
    (Trakya Univ Balkan Yerlesesi Enstituler Binasi, 2024) Akata, Ilgaz; Kumru, Eda; Sahin, Ergin; Acar, Ismail; Kaya, Ertugrul
    In the present study, fungal specimens collected from Ye & scedil;ildere village in U & scedil;ak province, T & uuml;rkiye were evaluated. The specimens underwent detailed examination through both morphological and DNA (nrITS rDNA region and TEF1a gene) sequence -based phylogenetic analysis. Based on the evaluation of micro- and macromorphological characteristics, and phylogenetic analyses, the specimen was identified as A. vidua Gasch, G. Moreno & P. A. Moreau. This identification marks A. vidua as a new record for the Turkish Amanita section Phalloideae. The study described this newly recorded species, including specific details such as its location, habitat observations, geographical coordinates, collection date, and photographs showcasing its macro and micromorphological features. Additionally, it also includes illustrations of some microscopic structures of the species. The study is further enriched with SEM images, offering a detailed view of the species characteristics, and the findings are briefly discussed.

    Antimicrobial potential of Xylaria polymorpha (Pers.) Grev.
    (Academic Journals, 2011) Hacioglu, Nurcihan; Akata, Ilgaz; Dulger, Basaran
    The ethanolic extracts obtained from the macrofungus Xylaria polymorpha (Pers.) Grev. (Ascomycetes) have been investigated for their antimicrobial activity. Growth inhibition using agar disc diffusion assays was determined against Escherichia coli ATCC 11230, S. aureus ATCC 6538P, Pseudomonas aeruginosa ATCC 27853, Proteus vulgaris ATCC 8427, Bacillus cereus ATCC 7064, Micrococcus luteus CCM 169, Candida albicans ATCC 10231, Rhodotorula rubra DSM 70403, Geotrichum capitatum ATCC 28576, Debaryomyces hansenii DSM 70238, Kluyveromyces fragilis ATCC 8608 and Cryptococcus neoformans ATCC 90112. As a result of study, we have found that X. polymorpha revealed antimicrobial activity against all tested microorganisms. Especially, G. capitatum is more susceptible to the extracts.

    Antiyeast Activity of Ethanolic Extract of Bjekandera adusta
    (Asian Journal Of Chemistry, 2010) Dulger, Basaran; Hacioglu, Nurcihan; Akata, Ilgaz
    Ethanolic extract of Bjekandera adusta (Wind.) P. Karst. was investigated for its antiyeast activity against Hanseniaspora guilliermondii, Rhodotorula rubra, Kluyveromyces fragilis, Kluyveromyces marxianus, Debaryomyces hansenii,Candida albicans. Candida glabrata, Candida utilis and Cryptococcus neoformans by disc diffusion method. The extracts. had strong effects against Candida albicans and Cryptococcus neoformans, but weak activity was seen against the other yeast cultures used in present study.

    Initial Report of Inocybe costinitii in Türkiye with Morphological and Molecular Data
    (2024) Akata, Ilgaz; Ediş, Gülce; Kumru, Eda; Acar, İsmail; Acar, İsmail; Şahin, Ergin; Şahin, Ergin
    Inocybe specimens were collected from Ankara University Beşevler 10. Yıl Campus, (Ankara, Türkiye) on October 19, 2022. As a result, the samples were identified as I. costinitii, a new record for Turkish Inocybe. This study presents a detailed description of this newly recorded species, covering aspects such as its location, observations of its habitat, geographical coordinates, the date of collection, and photographs that highlight its macroscopic and microscopic characteristics. Moreover, the study features the species' drawings and some of its microscopic traits. The study is enhanced by images obtained from a scanning electron microscope (SEM), briefly examining the spore features and discussed briefly.

    Taxonomic Studies on Rhodocybe asyae Specimens Discovered in a New Location
    (Kahramanmaras Sutcu Imam Univ Rektorlugu, 2024) Akata, Ilgaz; Edis, Gulce; Kumru, Eda; Acar, Ismail; Sahin, Ergin
    In 2023, fungal specimens were collected from the T & imath;naztepe Campus underwent a comprehensive and meticulous evaluation involving morphological examination and phylogenetic analysis based on nrITS rDNA sequencing. The DEU AKATA & SAHIN 148 samples exhibited microscopic and macroscopic characteristics that closely matched those of Rhodocybe asyae, initially described by Sesli & Vizzini. The genetic sequence analysis revealed over 99% similarity with R. asyae Sesli & Vizzini. This report represents the second recorded occurrence of R. asyae in T & uuml;rkiye and the third globally. The study documents the collection site, geographical coordinates, research provides macroscopic photographs, microscopic illustrations of the specimens, and detailed discussion, demonstrating the reliability of the present findings.
