In this study, 286 myxomycetes species identified to date were presented in Turkey. While there were 263 species in the 2016 published checklist, today the number of species has reached 286 after adding new records and removing synonyms. There was 6 Orders, 13 Families, 45 Genera in Turkey. The richest genera in terms of the number of species was Physarum and the proportion of myxomycete species in each taxonomic order was the largest order based on the number of species is the Physarida. S/G value indicating the richness of myxomycetes in one place, the species/genus ratio (S/G) was 6.35 of Turkey. This ratio was shown that Turkey was not poor of myxobiota but the study of Myxomycetes is still inadequate in Turkey. The names were arranged alphabetically. For each species, references were cited. An index of synonyms, based on literature records from Turkey was appended.
... Currently, recorded number of taxon of the genus Physarum is 25 and for the genus Didymium is 18 in Turkey 12,27 . In this study, we have reported three new species record for Turkish Myxomycetes: Physarum citrinum Schumach. ...
The ongoing global climate change is a very effective and important factor on the distribution and diversity of living organisms. As with all living populations, Myxomy-cetes are undoubtedly affected by pollutants, in particular by lead and sulphur dioxide emissions, but probably also to some extent by ozone and oxides of nitrogen with acid precipitation. Today, determining the presence and distribution in myxobiotic group of organisms is important to understand the aspects of biological diversity in ecosystems. In this study, three new species have been recorded and added to Turkish Myxomycetes. All of the specimens are collected from Marmara region of Anatolian Peninsula of Turkey. Despite the fact that two samples of Myxomycetes have been obtained from moist chamber application in the laboratory, the other sample has been isolated from interesting an exceptional manner on a part of potted plant and soil surface, indoor environment. These new records taxon are; Didymium dubium Ros-taf., Didymium verrucosporum A.L. Welden (Didymiaceae) and Physarum citrinum Schumach. (Physaraceae).
... and Inocybe quietiodor Bon were identified among these species. In the light of the literature on Turkish macrofungi (Solak et al., 2007;Solak et al., 2009;Sesli and Denchev, 2008;Demirel et al., 2010;Kaya et al., 2010;Allı, 2011;Allı et al., 2011;Demirel and Kaşık, 2012;Sesli and Kobayashi, 2014), these 2 taxa are new records for the Turkish mycota. The study aims to contribute to macromycota of Turkey by adding new generic records. ...
In the result of macroscopic and microscopic studies on samples of mushroom collected in Afyonkarahisar, Inocybe inconcinna P. Karst. and Inocybe quietiodor Bon taxa were determined to be new records in Turkey. Each species was given with the colour photographs and short descriptions.
... Many studies on Turkish mycobiota are being conducted especially last 20 years. In these studies many macrofungi taxa were recorded for the first time in Turkey (Akata, 2012;Akata et al., 2012;Demirel and Kaşık, 2012). All these studies contribute Turkey's biological diversity. ...
Clitocybe leucodiatreta Bon, Peziza echinospora P. Karst. and Psathyrella sacchariolens Enderle were
recorded for the first time from Turkey. The new reported taxa are described and illustrated.
In this study, 309 myxomycete species reported so far in Türkiye are listed. Previously, in the checklist published in 2019, 286 species were reported. With the addition of new records and the removal of synonyms, the number of species have reached to 309 today. These species belong to 5 orders, 12 families and 45 genera. Physarida and Physarum are the largest order and genus, respectively, containing the highest number of species. Türkiye is not poor in terms of myxobiota. However, studies on Myxomycetes in this country are still insufficient.
In this study, it was aimed to determine myxomycetes growing on materials collected from forests on Konya-Beyşehir (Turkey) highway route between 2019-2020. 253 materials such as log and stump materials, forest debris and bark of living tree were collected during the fieldworks in the region. The moist chamber technique was applied to the collected materials. As a result, 80 myxomycete specimens were developed and 21 myxomycete taxa belonging to 8 families were identified. The most common species is Perichaena depressa Lib. and was detected on 17 different substrates. In addition, the localities of the species (station number, substrate, collection date, collection number), and photographs of the species identified from the region are also given.
The genus Physarum, known as the largest genus in Physaraceae and in Myxomycetes as well, comprises more than 146 species all over the world, in Turkey 38 species.

ABSTRACT
Objective: Urbanization has been reported to affect the biodiversity of myxomycetes. There is no data in the Bursa city on
the diversity of myxomycete in the urban area. Therefore, we aim to determine the presence of corticolous myxomycetes on
monumental trees that are located in the most populated province of Bursa city (Osmangazi and Yıldırım).
Materials and Methods: In August and October 2018, 100 barks of monumental trees located in the Osmangazi and Yıldırım)
county of Bursa was collected. Moist chamber culture technique was used for the isolation and identification of the species.
Results: 16 species within 9 genera were identified. The species identified are listed, and six new species Didymium bahiense
(Gottsberger), Didymium difforme (Pers.) S. F. Gray), Macbrideola martinii (Alexop. & Beneke), Macbrideola oblonga (Pando,
Lado), Physarum gyrosum (Rost.), Physarum notabile (Macbr.) were recorded for Bursa city.
Conclusion: This is the first report of corticolous myxomycetes on monumental trees in Bursa city center. It also added data
and 6 new records of myxomycetes on the myxomycete biodiversity of Bursa.

Simple, rapid and selective procedures for the indirect spectrophotometric determination of trace amounts of As(III) using safranine O and determination of arsenic(V) using fuchsine as new reagents have been developed. The methods are based on the liberation of iodine by the reaction of arsenic(III) with potassium iodate and by the reaction of arsenic(V) with potassium iodide in acid medium. The liberated iodine, equivalent to each analyte, forms a complex with the indicators: for As(III)-safranine O system having an absorption maximum at λmax 532 nm and for As(V)-fuchsine system having an absorption maximum at λmax 540 nm. The different analytical parameters affecting determination processes have been examined. The methods detection limit, limit of quantification and molar absorptivity are reported as follows: for aresenic(III)-safranine O system are found to be 0.250 μg ml-1, 0.759 μg ml-1, 1.388 ×104 l mol-1cm-1. Respectively for arsenic(V)-fuchsine system the same data are found to be 0.053 μg ml-1, 0.161 μg ml-1, 2.11 ×104 l mol-1cm-1. These methods are designed for measurement of As(III) in the range of 0.04-11.5 mg l-1and As(V) species in the range of 0.05-10.0 mg l-1. The methods may be applicable for determination of arsenic species in environmental samples.
