Question: Do Calothamnus and Grewia belong to the same genus?

Context paragraphs:
Stereopsis (fungus): Stereopsis is the sole genus of fungi in the family Stereopsidaceae.  The genus was formerly placed in the family Meruliaceae in the order Polyporales but was found to belong in its own order along with the genus "Clavulicium".  "Stereopsis" was circumscribed by English mycologist Derek Reid in 1965.  It contains species that form funnel-shaped basidiocarps as well as the corticioid species "Stereopsis globosa" which was formerly considered a species of "Clavulicium".  The species "Stereopsis humphreyi" and "Stereopsis vitellina" were found to belong in the Agaricales and Atheliales respectively in a molecular phylogenetics study, and because of this do not belong in "Stereopsis", but they have not yet been transferred to their own genera.

Grewia: The large flowering plant genus Grewia is today placed by most authors in the mallow family Malvaceae, in the expanded sense as proposed by in the APG.  Formerly, it was placed in either the linden family (Tiliaceae) or the Sparrmanniaceae.  However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of "Grewia" and similar genera - and have thus been merged into the Malvaceae.  Together with the bulk of the former Sparrmanniaceae, "Grewia" is in the subfamily Grewioideae and therein the tribe Grewieae, of which it is the type genus.

Sheep–goat hybrid: A sheep–goat hybrid (sometimes called a geep or shoat in popular media) is the hybrid offspring of a sheep and a goat.  Although sheep and goats seem similar and can be mated, they belong to different genera in the subfamily Caprinae of the family Bovidae.  Sheep belong to the genus "Ovis" and have 54 chromosomes, while goats belong to the genus "Capra" and have 60 chromosomes.  The offspring of a sheep-goat pairing is generally stillborn.  Despite widespread shared pasturing of goats and sheep, hybrids are very rare, indicating the genetic distance between the two species.  Though sometimes called "geep", they are not to be confused with sheep–goat chimera, which are artificially created.

Calothamnus lehmannii: Calothamnus lehmannii, commonly known as dwarf claw flower, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia.  It is a low-lying, sometimes ground-hugging shrub with long, thin, cylindrical leaves and clusters of red flowers that are smaller than any others in the genus "Calothamnus".

List of Grewia species: The large flowering plant genus Grewia is today placed by most authors in the mallow family Malvaceae, in the expanded sense as proposed by in the APG.  Formerly, it was placed in either the linden family (Tiliaceae) or the Sparrmanniaceae.  However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of "Grewia" and similar genera - and have thus been merged into the Malvaceae.  Together with the bulk of the former Sparrmanniaceae, "Grewia" is in the subfamily Grewioideae and therein the tribe Grewieae, of which it is the type genus.

Kleinhovia: Kleinhovia hospita (guest tree syn.  "Kleinhovia serrata" , "Grewia meyeniana" ) is an evergreen, tropical tree native to Indonesia, Malaysia and other parts of tropical Asia.  It is monotypic, being the only species in the genus Kleinhovia.

Beaufortia (plant): Beaufortia is a genus of woody shrubs and small trees in the family Myrtaceae and is endemic to the south-west of Western Australia.  The genus "Beaufortia" is closely related to "Melaleuca", "Calothamnus", "Regelia" and several others, differing mainly in the way the anthers are attached to the stalks of the stamens, and in the way they open to release their pollen.  "Beaufortia" anthers are attached at one end and open by splitting at the other.

Tolypocladium: Tolypocladium is a genus of fungi within the family Ophiocordycipitaceae.  It includes species that are parasites of other fungi, insect pathogens, rotifer pathogens and soil inhabiting species with uncertain ecological roles.  "Tolypocladium" was originally circusmcribed as a genus containing anamorphic fungi.  It was later determined that some "Cordyceps"-like teleomorphic fungi were the teleomorphs of "Tolypocladium" species.  These species were considered to belong in the genus "Cordyceps" until molecular phylogenetics studies found these species to be more closely related to "Ophiocordyceps" and were considered to belong in that genus before they were transferred to the new genus "Elaphocordyceps" by Sung and colleagues in 2007.  However, under the ICN's 2011 "one fungus, one name" principle, fungi can not have different names for their anamorphic and teleomorphic stages if they are found to be the same taxon.  Quandt and colleagues formally synonymized "Tolypocladium" and "Elaphocordyceps" in 2014.  Quandt and colleagues also synonymized the anamorphic genus "Chaunopycnis" with "Tolypocladium".  The immunosuppressant drug ciclosporin was originally isolated from "Tolypocladium inflatum", and has since been found in other species of "Tolypocladium", some of which were formerly placed in "Chaunopycnis".

Calothamnus: Calothamnus is a genus of shrubs in the family Myrtaceae and is endemic to the south-west of Western Australia.  The common names one-sided bottlebrush or claw flower are given to some species due to their having the flowers clustered on one side of the stem or because of the claw-like appearance of their flowers.  "Calothamnus" species are generally medium to tall woody shrubs with crowded leaves.  In most species the leaves are crowded and linear in shape, and the flowers are usually arranged in dense clusters.  The petals are small and fall off the flower soon after it opens but the stamens are long, numerous and usually bright red.

Grewioideae: Grewioideae is a subfamily of the Malvaceae family.  The group is named after its type genus, "Grewia", which is named for the English scientist Nehemiah Grew (1641-1712).
