The present study aims to identify Neofusicoccum isolates collected from lotus with symptoms of dieback, blight, and wilted leaves. Species were identified based on their morphology and comparison of the DNA sequence data for ITS rDNA and β-tubulin (tub-2). The taxonomy and phylogenetic relationships of pathogen isolates were investigated, and their pathogenic abilities were determined.

Endometrial cancer studies have led to a number of well-defined but mechanistically unconnected genetic and environmental risk factors. One of the emerging modulators between environmental triggers and genetic expression is the microbiome. We set out to inquire about the composition of the uterine microbiome and its putative role in endometrial cancer.

Inocybe viscida sp. nov., a novel species found in a forest with old trees of Pinus brutia and tertiary relict endemic Liquidambar orientalis in coastal area of southwestern Turkey, is described and illustrated. We present this new species based on morphological and molecular data from nuclear rDNA internal transcribed spacer region (ITS1-5.8SITS2 = ITS) and the portions of nuc 28S rRNA (LSU) gene. Comprehensive description, field photographs, line drawings of the microscopic features and comparisons with phenetically similar taxa and phylogenetically related species are discussed.

In this study, we have sequences nuclear gene region (ITS-rDNA) from 9 individuals of Tacca chantrieri André belonging to three natural populations (Song Hinh Nature Reserve, Phu Yen Province; Cuc Phuong National Park, Ninh Binh province and Ba Vi National Park, Ha Noi city) to investigate genetic character and their phylogenetic inference in the genus Tacca. DNA was extracted from the tissue of leaves.

The Mediterranean cereal cyst nematode, Heterodera latipons, is an important plant parasitic nematode that negatively impacts cereal production worldwide, particularly in the Mediterranean Basin. Successful control of cereal cyst nematodes requires knowledge of the nematode species/pathotypes and their biology. However, little information is currently available concerning the phenotypic and genotypic variability of H. latipons populations in Turkey. This study analyzed the morphological/morphometric and genetic characteristics of Turkish H.

Capoeta kosswigi was described from Lake Van basin, Turkey, being close to C. damascina and C. umbla. It is distinguished from them by a pointed snout and a small horseshoe-shaped mouth, and differing from C. damascina by having smaller scales, and from the C. umbla by processing larger scales. In this study, we tested the suggested synonymy hypothesis of C. kosswigi and C. damascina by comparing the morphometric and meristic data. The results revealed that all morphometric and meristic characters of C. kosswigi overlap with those of C. damascina.

The current research was conducted on the fungal materials collected from Ankara, Balıkesir, and Kütahya provinces between 2015 and 2019. As a result of the field and laboratory studies, Conocybe dentatomarginata, Entoloma lampropus, Lactarius lilacinus, Otidea nannfeldtii and Sarcopeziza sicula are reported for the first time from Turkey based on macro- and micromorphological studies and internal transcribed spacer (ITS) rDNA-based molecular phylogeny. Descriptions of new records are provided together with photos showing their macro and micro-morphology.

Atriplex mollis Desf. (Amaranthaceae), a North African endemic halophytic species, is further described in this study. Phylogenetic analysis based on a combined dataset of ITS and ETS rDNA and atpB-rbcL and trnK cpDNA showed that A. mollis is closely related to the Malta- and Gozo-endemic Cremnophyton lanfrancoi Brullo & Pavone. Given this close phylogenetic relationship, A. mollis is also considered among the oldest species of Atriplex, together with C. lanfrancoi. Molecular data also suggest that A. mollis in North Africa, C. lanfrancoi on Malta Island, and Atriplex cana Ledeb.

A new species of Pseudocercospora is described causing leaf spot disease on Crotalaria assamica from India. The identity of isolate was based on asexual morphs, cultural characteristics and phylogenetic analyses of partial nuclear ribosomal 28S large subunit and complete internal transcribed spacer rDNA sequence data with high statistical support value. Morphologically this species has characters similar to allied species in genus Pseudocercospora but differs in having catenate and branched conidia.

Pluteus and Volvopluteus are two closely related genera of Pluteaceae that comprise saprotrophic fungi. Although the genera have been well-studied in Europe and North and South America, the diversity of Pluteus, mainly Pluteus sect. Pluteus, and Volvopluteus in Turkey is poorly known due to insufficient morphological descriptions and a lack of DNA sequence data. In this study, the diversity of Pluteus sect. Pluteus and Volvopluteus in Turkey is evaluated by employing both morphological features and phylogenetic approaches. A general phylogeny of Pluteus sect.
