ELECTRON-MICROSCOPIC EXAMINATION FROM AMNIOTIC EPITHELIUM COVERING THE PLACENTA AND UMBILICAL-CORD IN CASES OF POLYHYDRAMNIOS AND OLIGOHYDRAMNIOS

Totally 25 cases without any fetal anomaly, 10 with polyhydramnios, 10 with oligohydramnios and 5 with normal volume of amniotic fluid were taken into consideration. Their amnion covering the placenta and umbilical cord were examined under electron microscope. In the group with polyhydramnios the microvilli facing the amniotic cavity were denser in certain regions. The intercellular space was widened and the terminal bars were opened. Within the cells the number of vesicles were increased and there were large cysternas within these vesicles. It was postulated that the large cysternas found in the basal and apical parts of the cell were composed of macropinocytosic vesicles of the basal membran. In the group with oligohydramnios the microvilli on the apical side were diminished. The intercellular space of the lateral side was narrowed. The electron density of the basal lamina was increased. The cellular structures were apparently reduced having just a few vesicles and lipid granules. Both in polyhydramnios and oligohydramnios the amniotic epithel cells covering the placenta and umbilical cord are responsible for the transfer of the fluid into the amniotic cavity. Possibly they control the amount of fluid by reducing or increasing its passage

A false morel, gyromitra esculenta (Pers.) Fr. (Ascomycetes), poisoning in Turkey

A case of mushroom poisoning by false morel, Gyromitra esculenta (Pers.) Fr. (Ascomycetes), in Denizli, Turkey, is reported and documented. A short description of the taxon, case of poisoning, and taxonomic discussions of G. esculenta is presented. © 2009 by Begell House, Inc

Macrofungal diversity of Usak province in Turkey

This paper was based on macrofungal specimens collected from Usak, in years of 2006-2007. Field and laboratory studies revealed a total of 124 taxa belonging to 36 families and 2 classes. 11 taxa belong to Ascomycetes and 113 to Basidiomycetes. Nine of them; Coprinopsis echinospora, Cystoderma simulatum, Hohenbuehelia semi-infundibuliformis, Hygrophorus capreolarius, Inocybe leucoblema, Leucocoprinus lanzonii, Marasmius chordalis, Mycena renati, and Russula rhodopus are new records for Turkey.

Notes for genera – Ascomycota

Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10--15 years, and continues to accelerate. Several genera have been found to be polyphyletic, and their generic concepts have subsequently been emended. New names have thus been introduced for species which are phylogenetically distinct from the type species of particular genera. The ending of the separate naming of morphs of the same species in 2011, has also caused changes in fungal generic names. In order to facilitate access to all important changes, it was desirable to compile these in a single document. The present article provides a list of generic names of Ascomycota (approximately 6500 accepted names published to the end of 2016), including those which are lichen-forming. Notes and summaries of the changes since the last edition of `Ainsworth Bisby's Dictionary of the Fungi' in 2008 are provided. The notes include the number of accepted species, classification, type species (with location of the type material), culture availability, life-styles, distribution, and selected publications that have appeared since 2008. This work is intended to provide the foundation for updating the ascomycete component of the ``Without prejudice list of generic names of Fungi'' published in 2013, which will be developed into a list of protected generic names. This will be subjected to the XIXth International Botanical Congress in Shenzhen in July 2017 agreeing to a modification in the rules relating to protected lists, and scrutiny by procedures determined by the Nomenclature Committee for Fungi (NCF). The previously invalidly published generic names Barriopsis, Collophora (as Collophorina), Cryomyces, Dematiopleospora, Heterospora (as Heterosporicola), Lithophila, Palmomyces (as Palmaria) and Saxomyces are validated, as are two previously invalid family names, Bartaliniaceae and Wiesneriomycetaceae. Four species of Lalaria, which were invalidly published are transferred to Taphrina and validated as new combinations. Catenomycopsis Tibell Constant. is reduced under Chaenothecopsis Vain., while Dichomera Cooke is reduced under Botryosphaeria Ces. De Not. (Art. 59)
