Caenorhabditis elegans is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments. It is the type species of its genus. The name is a blend of the Greek caeno- (recent), rhabditis (rod-like) and Latin elegans (elegant). In 1900, Maupas initially named it Rhabditides elegans. Osche placed it in the subgenus Caenorhabditis in 1952, and in 1955, Dougherty raised Caenorhabditis to the status of genus.
Psilocybe cubensis is a species of psychedelic mushroom whose principal active compounds are psilocybin and psilocin. Commonly called shrooms, magic mushrooms, golden tops, cubes, or gold caps, it belongs to the fungus family Hymenogastraceae and was previously known as Stropharia cubensis. It is the most well known psilocybin mushroom due to its wide distribution and ease of cultivation.
Pinus thunbergii, also called black pine, Japanese black pine, and Japanese pine, is an East Asian pine native to coastal areas of Japan and South Korea.
The Strophariaceae are a family of fungi in the order Agaricales. Under an older classification, the family covered 18 genera and 1316 species. The species of Strophariaceae have red-brown to dark brown spore prints, while the spores themselves are smooth and have an apical germ pore. These agarics are also characterized by having a cutis-type pileipellis. Ecologically, all species in this group are saprotrophs, growing on various kinds of decaying organic matter. The family was circumscribed in 1946 by mycologists Rolf Singer and Alexander H. Smith.
Acanthocyte, in biology and medicine, refers to an abnormal form of red blood cell that has a spiked cell membrane, due to thorny projections. A similar term is spur cells. Often they may be confused with echinocytes or schistocytes.
Coprinus comatus, the shaggy ink cap, lawyer's wig, or shaggy mane, is a common fungus often seen growing on lawns, along gravel roads and waste areas. The young fruit bodies first appear as white cylinders emerging from the ground, then the bell-shaped caps open out. The caps are white, and covered with scales—this is the origin of the common names of the fungus. The gills beneath the cap are white, then pink, then turn black and secrete a black liquid filled with spores. This mushroom is unusual because it will turn black and dissolve itself in a matter of hours after being picked or depositing spores.
Stropharia rugosoannulata, commonly known as the wine cap stropharia, "garden giant", burgundy mushroom or king stropharia, is an agaric of the family Strophariaceae found in Europe and North America, and introduced to Australia and New Zealand. The mushroom was reported in April 2018 in Colombia, in the city of Bogota. Unlike many other members of the genus Stropharia, it is regarded as a choice edible and is commercially cultivated.
The genus Stropharia is a group of medium to large agarics with a distinct membranous ring on the stipe. Well-known members of this genus include the edible Stropharia rugosoannulata and the blue-green verdigris agarics. Stropharia are not generally regarded as good to eat and there are doubts over the edibility of several species. However the species Stropharia rugosoannulata is regarded as prized and delicious when young, and is now the premier mushroom for outdoor bed culture by mycophiles in temperate climates.
Nematophagous fungi are carnivorous fungi specialized in trapping and digesting nematodes. Around 160 species are known. There exist both species that live inside the nematodes from the beginning and others that catch them, mostly with glue traps or in rings, some of which constrict on contact. Some species possess both types of traps. Another technique is to stun the nematodes using toxins, which is a method employed by Coprinus comatus, Stropharia rugosoannulata, and the family Pleurotaceae. The habit of feeding on nematodes has arisen many times among fungi, as is demonstrated by the fact that nematophagous species are found in all major fungal groups. Nematophagous fungi can be useful in controlling those nematodes that eat crops. Purpureocillium, for example, can be used as a bio-nematicide.
Stropharia aeruginosa, commonly known as the verdigris agaric, is a medium-sized green, slimy woodland mushroom, found on lawns, mulch and woodland from spring to autumn. The edibility of this mushroom is controversial - some sources claim that it is edible, while others claim it to be poisonous, although effects are little known and its toxic constituents undescribed.
Pholiota is a genus of small to medium-sized, fleshy mushrooms in the family Strophariaceae. They are saprobes that typically live on wood. The genus has a widespread distribution, especially in temperate regions, and contains about 150 species.

The nematodes or roundworms constitute the phylum Nematoda, with plant-parasitic nematodes being known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Taxonomically, they are classified along with insects and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades they have a reduced number of Hox genes, but as their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, it shows that the reduction has occurred within the nematode phylum.
Capillaria hepatica is a parasitic nematode which causes hepatic capillariasis in rodents and numerous other mammal species, including humans. The life cycle of C. hepatica may be completed in a single host species. However, the eggs, which are laid in the liver, must mature outside of the host body prior to infecting a new host. So the death of the host in which the adults reach sexual maturity, either by being eaten or dying and decomposing, is necessary for completion of the life cycle.
Acanthocyte is a form of red blood cell that has a spiked cell membrane, due to abnormal thorny projections.
Protostropharia semiglobata, commonly known as the dung roundhead, the halfglobe mushroom, or the hemispheric stropharia, is an agaric fungus of the family Strophariaceae. A common and widespread species with a cosmopolitan distribution, the fungus produces mushrooms on the dung of various wild and domesticated herbivores. The mushrooms have hemispherical straw yellow to buff-tan caps measuring 1–4 cm (0.4–1.6 in), greyish gills that become dark brown in age, and a slender, smooth stem 3–12 cm (1.2–4.7 in) long with a fragile ring.
Protostropharia, is a coprophilous agaric fungal genus that produces glutinous, mostly yellowish to yellow brown fruit bodies. Characteristically most form chrysocystidia and rather large, smooth, violaceous basidiospores each with a prominent germ pore. It is differentiated from Stropharia by production of astrocystidia on its mycelium rather than by acanthocytes that Stropharia produces. Phylogenetically, Protostropharia is distinct from Stropharia, Pholiota, and Leratiomyces. Two species, P. luteonitens and P. tuberosa, form pseudosclerotia in the dung substrates.
Protostropharia alcis is a species of coprophilous agaric fungus in the family Strophariaceae. It was originally described by Finnish mycologist Ilkka Kytövuori in 1999, as one of six species in the "Stropharia semiglobata" group in northwestern Europe. The fungus produces fruit bodies on moose [known in Europe as European elk] dung. In 2013, the fungus named after Alces alces was transferred by Redhead et al. to Protostropharia, a genus circumscribed to contain Stropharia species characterized by the formation of astrocystidia rather than acanthocytes on their mycelium. In addition to Europe, the species has also been recorded in Brazil. The variety austrobrasiliensis was described from Rio Grande do Sul in 2008, where it grows on cow dung, or dung-enriched soil.
Stropharia caerulea, commonly known as the blue roundhead, is an inedible species of agaric fungus in the family Strophariaceae. It is a common species found in Europe and North America, where it grows as a saprophyte in meadows, roadsides, hedgerows, gardens, and woodchip mulch. S. caerulea was officially described to science in 1979, although it was known to be a distinct species for about two centuries before that. The taxon Stropharia cyanea, as defined by Risto Tuomikoski in 1953, and used by several later authors, is a synonym of S. caerulea.
Cry6Aa is a toxic crystal protein generated by the bacterial family Bacillus thuringiensis during sporulation. This protein is a member of the alpha pore forming toxins family, which gives it insecticidal qualities advantageous in agricultural pest control. Each Cry protein has some level of target specificity; Cry6Aa has specific toxic action against coleopteran insects and nematodes. The corresponding B. thuringiensis gene, cry6aa, is located on bacterial plasmids. Along with several other Cry protein genes, cry6aa can be genetically recombined in Bt corn and Bt cotton so the plants produce specific toxins. Insects are developing resistance to the most commonly inserted proteins like Cry1Ac. Since Cry6Aa proteins function differently than other Cry proteins, they are combined with other proteins to decrease the development of pest resistance. Recent studies suggest this protein functions better in combination with other virulence factors such as other Cry proteins and metalloproteinases.
