Didymium Wildpretii
''Didymium wildpretii'' is a species of slime mold which feeds on the decaying remains of various species of cacti. It was first described in 2007 and has been found across Mexico and the Canary Islands, but may be present where other cacti grow. Its sporocarps are short (0.1–0.7 mm tall); their sporotheca is pale yellow with an orange stalk and their spores have a diameter of 7.5 μm. When grown on agar, it completes its life cycle in 28–56 days. It grows on basic media with a pH of 7.8–10.0, with optimum growth occurring at 8.5–9.4. The species was named after Wolfredo Wildpret de la Torre, an expert in the flora of the Canary Islands. Hosts ''Didymium wildpretii'' is known to grow on species of the globose cacti '' Echinocactus platyacanthus'', '' Mammillaria carnea'' and '' Ferocactus latispinus''; the opuntioid cacti '' Opuntia depressa'', '' O. maxima'', '' O. pilifera'' and '' O. tomentosa'') and the columnar cacti ('' Myrtillocactus geometrizans'', ' ...

Slime Mold
Slime mold or slime mould is an informal name given to several kinds of unrelated eukaryotic organisms with a life cycle that includes a free-living single-celled stage and the formation of spores. Spores are often produced in macroscopic multicellular or multinucleate fruiting bodies which may be formed through aggregation or fusion. Slime molds were formerly classified as fungi but are no longer considered part of that kingdom. Although not forming a single monophyletic clade, they are grouped within the paraphyletic group Protista. More than 900 species of slime mold occur globally. Their common name refers to part of some of these organisms' life cycles where they can appear as gelatinous "slime". This is mostly seen with the Myxogastria, which are the only macroscopic slime molds. Most slime molds are smaller than a few centimetres, but some species may reach sizes up to several square metres and masses up to 20 kilograms. They feed on microorganisms that live in ...

Opuntia Depressa
''Opuntia'', commonly called prickly pear or pear cactus, is a genus of flowering plants in the cactus family Cactaceae.

Neobuxbaumia
''Cephalocereus'' is a genus of slow-growing, columnar-shaped, blue-green cactus, cacti. The genus is native to Mexico.

Ferocactus Latispinus
''Ferocactus latispinus'' is a species of barrel cactus native to Mexico. Originally described as ''Cactus latispinus'' in 1824 by English naturalist Adrian Hardy Haworth, it gained its current name in 1922 with the erection of the genus ''Ferocactus'' by American botanists Britton and Rose. The species name is derived from the Latin ''latus'' "broad", and ''spinus'' "spine". ''Ferocactus recurvus'' is a former name for the species.

Cacti
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, ...
