Habitat & Geographic Range

Common Rustgill

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Distributed across Belgium, Denmark, Norway, Portugal, and Sweden.

Green Sea Turtle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 8 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Australia, Brazil, Costa Rica, Indonesia, and Mexico. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Rustgill

<em>Gymnopilus penetrans</em>, the common rustgill, is a saprotrophic basidiomycete fungus in the family Hymenogastraceae, commonly found across temperate regions of Europe and beyond. It has been recorded in Belgium, Denmark, Norway, Portugal, and Sweden, typically fruiting on decaying conifer wood, stumps, buried roots, and woody debris in forests and woodland habitats. The fruiting bodies are small to medium-sized mushrooms with tawny orange to rust-brown caps, typically 2–7 centimeters in diameter, and bright rusty-orange gills that give the species its common name. The stem is similarly colored and typically fibrous. As a wood-decaying fungus, common rustgill plays an important ecological role in the decomposition of dead conifer timber and the recycling of nutrients in forest ecosystems. The species produces minute, roughened, rusty-brown spores. It is assessed as Least Concern on the IUCN Red List. The common rustgill typically fruits from late summer through autumn. It may occasionally be confused with related <em>Gymnopilus</em> species; some members of the genus contain potentially toxic or psychoactive compounds, though <em>G. penetrans</em> is generally considered of low toxicity. Biological traits such as average lifespan and detailed dietary substrate specificity remain poorly documented in comprehensive ecological databases.

Green Sea Turtle

The green sea turtle is one of the largest sea turtles. They are named for the green color of their cartilage and fat, not their shells.
