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.

Zwerg-Nestling

<em>Mycocalia denudata</em>, the common mycocalia, is a species of nidulariales fungus in the family Nidulariaceae, commonly known as bird's nest fungi due to the resemblance of their fruiting bodies to tiny nests containing eggs. <em>Mycocalia denudata</em> is a saprotrophic species that typically grows on decaying wood, plant debris, and humus-rich substrates in moist temperate forests. The minute cup-shaped fruiting bodies contain peridioles — small lens-shaped structures containing spores — which are dispersed by raindrops splashing into the nest, propelling them outward. Its geographic range includes Europe, with documented occurrences in Belgium, Denmark, Norway, and Sweden. The species is currently assessed as Least Concern by the IUCN, reflecting its adaptability to a range of decomposing substrates in temperate woodland and forest edge habitats. Biological traits such as lifespan, body size, and diet remain poorly documented for this species in the formal scientific literature. As a saprotroph, <em>Mycocalia denudata</em> contributes to nutrient cycling and decomposition processes in forest ecosystems, breaking down lignocellulosic material and returning organic matter to the soil.

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.
