Ashen crust (Peniophora lycii) is a species in the genus Peniophora. It is listed as Least Concern on the IUCN Red List. Typically found in forest floors, decomposing wood, and soil ecosystems.

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.
