In this contribution, new data concerning Algae, bryophytes, fungi and lichens of the Italian flora are presented. It includes records confirmations for algal genus Nitella , bryophyte genera Anthoceros Dicranodontium Fontinalis Riccia fungal Inocybe Xerophorus lichen Bagliettoa Biatora Calicium Cladonia Coniocarpon Lecanora Opegrapha Placynthium Rhizocarpon Scytinium Solenopsora Stereocaulon V...

Previous lichenometric dating of young geomorphological forms in the Tatra Mountains has been hindered by differences determination initial colonisation fresh rock surfaces Rhizocarpon geographicum lichen. In order to determine precisely time needed for first thalli appear on newly exposed surfaces, two experimental sites were created 2013. The results from these compared with measurements take...

The lichen specimens belonging to the order Lecanorales were collected from calcareous rocks in various areas of Mashhad. (Khorasan province). Specimens were taken back to the laboratory and identified. The identification of the species is based on morphology, anatomy and chemistry. They compose of  8  taxa  belonging  to 7 genera, namely, Lecanora conferta, L. muralis, Rhizocarpon umbilicatum,...

The responses of microorganisms (viruses, bacterial cells, bacterial and fungal spores, and lichens) to selected factors of space (microgravity, galactic cosmic radiation, solar UV radiation, and space vacuum) were determined in space and laboratory simulation experiments. In general, microorganisms tend to thrive in the space flight environment in terms of enhanced growth parameters and a demo...
