Question: Are Calotropis and Mesquite both types of genera?
Context: Attalea is a large genus of palms native to Mexico, the Caribbean, Central and South America.  This pinnately leaved, non-spiny genus includes both small palms lacking an aboveground stem and large trees.  The genus has a complicated taxonomic history, and has often been split into four or five genera based on differences in the male flowers.  Since the genera can only be distinguished on the basis of their male flowers, the existence of intermediate flower types and the existence of hybrids between different genera has been used as an argument for keeping them all in the same genus.  This has been supported by a recent molecular phylogeny. Loricifera (from Latin, "lorica", corselet (armour) + "ferre", to bear) is a phylum of very small to microscopic marine cycloneuralian sediment-dwelling animals with 37 described species, in nine genera.  Aside from these described species, there are approximately 100 more that have been collected and not yet described.  Their sizes range from 100 µm to ca. 1 mm.  They are characterised by a protective outer case called a lorica and their habitat, which is in the spaces between marine gravel to which they attach themselves.  The phylum was discovered in 1983 by Roberto Ramos, in Roscoff, France.  They are among the most recently discovered groups of Metazoans.  They attach themselves quite firmly to the substrate, and hence remained undiscovered for so long.  The first specimen was collected in the 1970s, and later described in 1983.  They are found at all depths, in different sediment types, and in all latitudes. Mesquite is the common name for the genus "Prosopis", containing over 40 species of small leguminous trees.  They are native to the southwestern United States and Mexico (even the creeping mesquite, which is invasive in southern California). Dermatophytes (derived from Greek "δέρματος" (dermatos), from "δέρμα", which means "skin" and -"phyte", from "phutón", meaning "plant" ) are a common label for a group of three types of fungus that commonly causes skin disease in animals and humans.  These anamorphic (asexual or imperfect fungi) genera are: "Microsporum", "Epidermophyton" and "Trichophyton".  There are about 40 species in these three genera.  Species capable of reproducing sexually belong in the teleomorphic genus Arthroderma, of the Ascomycota (see Teleomorph, anamorph and holomorph for more information on this type of fungal life cycle). Bucephalidae is a family of trematode flatworms that parasitize fish.  They lack suckers, having instead a muscular organ called a "rhynchus" at the front end which they use to attach to their hosts.  The characteristics of the rhynchus are used to help define the genera of the family.  It is one of the largest digenean families, with 25 genera containing hundreds of described species.  Bucephalids are cosmopolitan, having been recorded all over the world.  They are parasites of fish from freshwater, marine, and brackish water habitat types. Lichenomphalia is both a basidiolichen and an agaric genus.  Most of the species have inconspicuous lichenized thalli that consist of scattered, small, loose, nearly microscopic green balls or foliose small flakes containing single-celled green algae in the genus "Coccomyxa", all interconnected by a loose network of hyphae.  The agaric fruit bodies themselves are nonlichenized and resemble other types of omphalinoid mushrooms.  These agarics lack clamp connections and do not form hymenial cystidia.  The basidiospores are hyaline, smooth, thin-walled, and nonamyloid.  Most of the species were originally classified in the genera "Omphalina" or "Gerronema".  Historically the species were classified with those other genera in the family, the Tricholomataceae together with the nonlichenized species.  "Lichenomphalia" species can be grouped into brightly colored taxa, with vivid yellow and orange colors, versus the grey brown group, depending upon the microscopic pigmentation deposits.  Molecular research comparing DNA sequences now place "Lichenomphalia" close to the redefined genus "Arrhenia", which together with several other genera not traditionally considered to be related, fall within the newly redefined Hygrophoraceae. Calotropis is a genus of flowering plants in the dogbane family, Apocynaceae, first described as a genus in 1810.  It is native to southern Asia and North Africa. The Zygnematacae are a family of filamentous or unicellular, uniseriate (unbranched) green algae.  The filaments are septated and reproduction is by conjugation; "Spirogyra" is commonly used in schools to demonstrate this kind of reproduction.  The family is notable for its diversely shaped chloroplasts, such as stellate in "Zygnema", helical in "Spirogyra", and flat in "Mougeotia".  The Zygnemataceae are cosmopolitan, but though all generally occur in the same types of habitats, "Mougeotia", "Spirogyra", and "Zygnema" are by far the most common; in one study across North America, 95% of the Zygnemataceae collected were in these three genera.  Classification and identification is primarily by the morphology of the conjugation, which is somewhat rare to find in natural populations of permanent water bodies; when in the vegetative state, the rarer genera resemble the three most common, and are often mistaken for them and catalogued as such.  Conjugation can be induced in low-nitrogen culture.  While they occupy many habitats, in North America all are found solely in freshwater or subaerial habitats.  Species typically exist as floating mats in stagnant water in ditches and ponds, but some also grow in moving water, attaching themselves to a substrate by rhizoid-like projections of the basal cells of the filament.  The mat species rise to the surface in early spring, grow rapidly through the summer, disappearing by late summer.  Members of the Zygnemataceae, such as "Spirogyra", fall prey to parasites, especially chytrids. The fungal order Agaricales, also known as gilled mushrooms (for their distinctive gills) or euagarics, contains some of the most familiar types of mushrooms.  The order has 33 extant families, 413 genera, and over 13000 described species, along with six extinct genera known only from the fossil record.  They range from the ubiquitous common mushroom to the deadly destroying angel and the hallucinogenic fly agaric to the bioluminescent jack-o-lantern mushroom. The list of cloud types is a summarisation of the modern systems of cloud classification used in the troposphere, stratosphere, and mesosphere.  The ten basic genus-types in the troposphere have Latin names derived from five physical "forms".  These are, in approximate ascending order of instability or convective activity: "stratiform" sheets; "cirriform" wisps and patches; "stratocumuliform" patches, rolls, and ripples; "cumuliform" heaps and tufts, and "cumulonimbiform" towers that often have complex structures.  The forms are cross-classified by altitude range or level into ten basic genus types.  Most genera are divided into "species", some of which are common to more than one genus.  Most genera and species can be subdivided into "varieties", also with Latin names, some of which are common to more than one genus or species.  The essentials of the modern nomenclature system for tropospheric clouds were proposed by Luke Howard, a British manufacturing chemist and an amateur meteorologist with broad interests in science, in an 1802 presentation to the Askesian Society.  Since 1890, clouds have been classified and illustrated in cloud atlases.  Mesospheric and stratospheric clouds have their own classifications with common names for the major types and alpha-numeric nomenclature for the subtypes.
