Clay-Gilled Milkcap

The Clay-gilled Milkcap, Lactarius helvus, is a medium to large mushroom in the family Russulaceae, notable for its distinctive fenugreek-like or curry-like scent when fresh or dried. The cap is typically dry, pale buff to pale brick-brown, and convex becoming flat or centrally depressed with age. The gills are closely spaced, crowded, and pale clay to buff in color, giving rise to the common name. When cut or broken, the flesh exudes a watery, mild to faintly acrid white latex, characteristic of the genus Lactarius. The Clay-gilled Milkcap is ectomycorrhizal, forming associations primarily with spruce and pine in boreal and montane forests of Europe, North America, and northern Asia. It fruits from late summer through autumn in coniferous forests, often in large numbers following rainy periods. Although widely consumed in parts of Eastern Europe after prolonged boiling and processing, the raw mushroom contains sesquiterpene lactones that can cause gastrointestinal distress and is considered mildly toxic if eaten without preparation. Its dried form is used as a spice substitute in some traditional recipes due to its aromatic qualities. The species is widespread and not considered threatened within its boreal and montane conifer forest range.

koala

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.
