Coccomyces coronatus is a discomycete fungus in the family Rhytismataceae, a group of ascomycetes specialized in the colonization and decomposition of dead plant material, particularly fallen leaves and decaying vegetation in temperate woodland ecosystems. The genus Coccomyces encompasses numerous species that produce small, inconspicuous apothecia—the cup-shaped or disc-shaped sexual fruiting bodies characteristic of discomycetes—embedded in or erupting from the surfaces of decaying leaves and plant debris. Coccomyces coronatus has been documented from European temperate forests, where it colonizes the dead leaves of deciduous trees, contributing to the decomposition of leaf litter and the cycling of nutrients back into the soil ecosystem. The fruiting bodies are typically dark, disc-shaped, and minute, often requiring hand lens or microscopic examination to observe in detail. Like other rhytismatacean fungi, C. coronatus produces ascospores that are discharged from the asci within the apothecium and dispersed by air currents or water splash to colonize new substrate. The specific epithet 'coronatus' likely refers to a crown-like or crownate morphological feature of the fruiting body or spore apparatus. As a saprotrophic organism, this fungus plays an important functional role in forest floor decomposition, breaking down recalcitrant leaf material alongside bacteria, invertebrates, and other fungi. Its conservation status has not been evaluated by the IUCN.

Complex-toothed Flying Squirrel

<em>Trogopterus xanthipes</em>, the complex-toothed flying squirrel, is a medium-sized gliding rodent in the family Pteromyidae endemic to China, where it inhabits montane broadleaf and mixed forests at elevations typically between 1,000 and 2,700 metres in provinces including Sichuan, Yunnan, Guizhou, Hubei, and neighbouring regions. This species is the sole member of the genus Trogopterus and is distinguished by complex tooth morphology compared to other flying squirrels. Like all flying squirrels, it possesses a patagium — a gliding membrane stretching between fore and hind limbs — that enables it to glide between trees rather than undertake powered flight. The complex-toothed flying squirrel is nocturnal and arboreal, spending its days sheltering in tree hollows and foraging at night for leaves, bark, seeds, and fungi. Its faeces, known as Wuflingzhi, have been used in traditional Chinese medicine for centuries, leading to trapping pressure in parts of its range. The IUCN classifies this species as Near Threatened, reflecting population decline driven by overhunting for medicinal use and ongoing habitat loss from logging and agricultural encroachment in montane forests. Biological traits including average body mass, lifespan, litter size, and home range are partially documented but detailed population estimates are limited. Conservation measures include legal protections under Chinese wildlife law.
