Common Porecrust

The Common Porecrust, <em>Schizophyllum commune</em>, is one of the most widely distributed fungi on Earth, belonging to the family Schizophyllaceae within the order Agaricales. It is a wood-decay bracket fungus found on dead and dying hardwood trees, logs, and stumps across virtually every vegetated continent, including Africa, Asia, Europe, and the Americas. The species is readily identified by its small, fan-shaped to lobed, hairy gray-white fruiting bodies and its distinctive split gill-like structures on the underside, which give it the common name split-gill fungus. <em>Schizophyllum commune</em> typically fruits year-round in humid conditions and is capable of surviving extreme desiccation, reviving when moisture returns. It plays an important ecological role as a saprotrophic decomposer of lignocellulosic material, contributing to nutrient cycling in forest ecosystems. The species is also notable as an opportunistic pathogen in immunocompromised humans, occasionally causing pulmonary or sinus infections. It is assessed as Least Concern on the IUCN Red List owing to its vast range and abundance. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.

Comoro Flying Fox

<em>Pteropus livingstonii</em>, the Comoro flying fox or Livingstone's fruit bat, is a large fruit bat in the family Pteropodidae, endemic to the Comoro Islands in the western Indian Ocean, where it is restricted to Anjouan and Mohéli. It is one of the largest bats in the world, with a wingspan that can exceed one meter and a body weight reportedly ranging between 400–700 g. The species roosts colonially in tall native forest trees, particularly in humid upland forest fragments, and feeds on a variety of native fruits, nectar, and pollen, playing a critical role as a seed disperser and pollinator in Comoran forest ecosystems. Precise average lifespan data in the wild remain poorly documented, though captive individuals have lived over 20 years. <em>Pteropus livingstonii</em> is assessed as Critically Endangered by the IUCN, making it one of the most threatened bat species in the world. Primary threats include extensive deforestation driven by agricultural expansion and charcoal production, which has severely reduced suitable roosting and foraging habitat, along with historic hunting. Conservation efforts include habitat protection, community education programs, and captive breeding initiatives at several European zoos coordinated through an international species survival program.
