Horse outward similarity is an unreliable measure of relatedness. Besides the horse, there are six other species of genus "Equus" in the Equidae family. These are the ass or donkey, "Equus asinus"; the mountain zebra, "Equus zebra"; plains zebra, "Equus quagga"; Grévy's zebra, "Equus grevyi"; the kiang, "Equus kiang"; and the onager, "Equus hemionus". Horses can crossbreed with other members of their genus. The most common hybrid is the mule, a cross between a "jack" (male donkey) and a mare. A related hybrid, a hinny, is a cross between a stallion and a jenny (female donkey). Other hybrids include the zorse,
Gloeoporus africanus Gloeoporus africanus Gloeoporus africanus is a species of crust fungus in the family Irpicaceae. Found in Africa, it was described as a new species in 2018 by Paul Jung and Young Wood Lim. The type collection was made in Bwindi Impenetrable National Park, Uganda, where it was found growing on a fallen branch. It is somewhat similar in appearance to "Bjerkandera adusta", but is distinguished from that fungus by its angular pores and the white edges of the actively growing pore surface. "G. africanus" has a monomitic hyphal system, and its generative hyphae have clamp connections. Its spores are sausage-shaped
