Chroococcus westii is a species of cyanobacteria in the family Chroococcaceae, likely named in honor of a naturalist or phycologist named West, following the common nineteenth and early twentieth century tradition of naming newly described microorganisms after prominent researchers in the field. The species belongs to a genus of simple, spherical cyanobacteria that occur in pairs or small groups within gelatinous sheaths in freshwater and aquatic environments. Chroococcus westii has been documented from freshwater habitats, contributing to the cyanobacterial diversity of lakes, pools, and associated periphyton communities. Cyanobacteria of the Chroococcaceae are among the foundational components of freshwater microbial ecosystems, contributing to primary production, biofilm formation, and in some lineages, biological nitrogen fixation. The taxonomy of the genus Chroococcus has undergone revision through the application of modern molecular phylogenetic methods, which have revealed that morphologically similar coccoid cyanobacteria can be phylogenetically distant, suggesting the need for further taxonomic work. Chroococcus westii is a relatively obscure species documented primarily in classical phycological literature. It has not received formal IUCN assessment.

Coastal Mushoom

Agaricus litoralis, the coastal mushroom, is a saprotrophic agaric fungus in the family Agaricaceae occurring in sand dunes, coastal grassland, and sandy soil habitats along the coasts of northwestern Europe, with confirmed records from Belgium, Denmark, Norway, and Sweden. The genus Agaricus contains the familiar cultivated button mushroom (A. bisporus) along with hundreds of wild species, and members are characterized by a ring on the stem and browning, discoloring, or non-discoloring flesh when cut, features used in field identification. Agaricus litoralis is a medium-sized mushroom producing white to cream-colored caps 4–10 centimeters across with pinkish then dark brown gills and a stout stem with a double ring, fruiting in sand dune hollows and the grassy margins of coastal habitats from summer through autumn. The specific epithet litoralis refers directly to its coastal habitat preference. As a saprotroph, it decomposes organic matter in the sandy soil substrate, releasing nutrients back into the ecosystem. The species is classified as Least Concern by the IUCN, being relatively widespread in suitable coastal sandy habitat across northwestern Europe. Like many coastal fungi, it is specifically adapted to the nutrient-poor, well-drained, alkaline conditions of stabilized sand dune systems.
