.. jAlbum 39.6 The protosteloid amoebae, or protosteloids (formerly known as protostelids), are a group of terrestrial amoebae capable of developing a tiny fruiting body or sporocarp consisting of a stalk supporting one or more spores. They do not form a natural group; instead, they have gained the sporocarp-forming ability independently from each other during evolution. Protosteloid amoebae are capable of making simple fruiting bodies consisting of a cellular stalk topped by one or a few spores. These are known as sporocarps. All species are microscopic and are typically found on dead plant matter where they consume bacteria, yeasts, and fungal spores. Since protostelids are amoebae that make spores, they are considered to be slime molds. Protosteloid amoebae are terrestrial, typically found on dead plant matter, including stems and leaves of herbaceous plants, stems and leaves of grasses, bark of living trees, decaying wood and other types of dead plant matter. Some species are aquatic; they live on dead plant parts submerged in a pond. Others live on the petals of living flowers and on living tree leaves. Since protosteloid amoebae eat bacteria, yeasts, and fungal spores in the laboratory, it is thought that they also do this in nature. They are thus thought to be predators in decomposer communities. https://fungarium.info/%D0%9F%D1%80%D0%BE%D1%82%D0%BE%D1%81%D1%82%D0%B5%D0%BB%D0%B8%D0%BE%D0%BC%D0%B8%D1%86%D0%B5%D1%82%D1%8B%20-%20Protosteliomycetes/
