Habitat & Geographic Range

Black Bent

Habitat

Inhabits tropical and subtropical moist broadleaf forests within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (South Africa), Asia (Japan), Europe (11 countries), North America (4 countries), Oceania and the Pacific (Australia), and South America (5 countries).

Clustered Bracket

Habitat

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

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and North America (United States). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Black Bent

The Black Bent (Agrostis gigantea) is a species in the genus Agrostis. It is currently classified as Least Concern on the IUCN Red List. Inhabits tropical and subtropical moist broadleaf forests within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Clustered Bracket

Inonotus cuticularis, the clustered bracket, is a polypore fungus in the family Hymenochaetaceae that grows on living and dead hardwood trees across the northern hemisphere. The fruiting bodies are bracket-shaped, overlapping in tiered clusters, with a yellowish-brown to rusty-brown upper surface that darkens with age, and a pale to golden pore surface beneath. This species causes white heart rot in its host trees, degrading the structural integrity of trunks and major branches. It commonly attacks living oaks, beeches, and other broadleaf trees, as well as occurring on dead wood. Inonotus cuticularis is listed as Vulnerable by the IUCN, reflecting its association with old-growth and veteran trees that are increasingly rare in managed European and North American landscapes. The decline of old-growth forest and the removal of veteran trees from managed woodlands and parklands has reduced suitable habitat for many bracket fungi. Conservation of ancient and veteran trees is therefore important for maintaining populations of this and many other wood-decay fungi with similar old-growth associations.
