Ege-kalkplet

**Ege-kalkplet (Dendrothele commixta)** Dendrothele commixta is a crustose lichen species characterized by its thin, whitish to pale gray thallus that forms irregular patches on substrate surfaces. The species produces small, black apothecia (fruiting bodies) that are typically immersed in the thallus. As a lichen, it represents a symbiotic relationship between fungal and algal components, contributing to ecosystem functions through nutrient cycling and serving as a food source for various invertebrates and some vertebrates. This species demonstrates a remarkably broad geographic distribution, occurring across multiple continents including Europe (Sweden, Denmark, Finland, Norway, Germany, United Kingdom, France, Spain, Italy, Austria, Switzerland, Belgium, Netherlands, Portugal, Slovakia, Ukraine, Russia), North America (United States, Canada), Oceania (Australia, New Zealand), Asia (Nepal), Africa (Cameroon), and the Caribbean (Jamaica). It inhabits terrestrial environments, typically growing on calcareous substrates such as limestone rocks, concrete structures, and mortar. Despite its wide distribution, Dendrothele commixta is classified as Endangered, though specific threats have not been formally assessed. The population trend remains unknown, indicating significant knowledge gaps in understanding this species' conservation status. Current conservation measures for this lichen species are not well-documented, reflecting the general lack of targeted conservation programs for cryptogamic species. The species' broad distribution may provide some resilience, but without comprehensive threat assessment or population monitoring, its long-term trajectory remains uncertain. Enhanced taxonomic research and habitat monitoring are needed to better understand its conservation requirements.
