Eriophorum (cottongrass, cotton-grass or cottonsedge) is a genus of flowering plants in the family Cyperaceae, the sedge family.
 They are found throughout the arctic, subarctic and temperate portions of the Northern Hemisphere in acid bog habitats, being particularly abundant in Arctic tundra regions.
Cirsium eriophorum or woolly thistle is a herbaceous biennial species of the genus "Cirsium".
 It is widespread across much of Europe.
 It is a large, biennial herb with sharp spines on the tips of the leaves, and long, woolly hairs on much of the herbage.
 Flower heads are large and nearly spherical, with spines on the outside and many purple disc florets but no ray florets.
Muromegalovirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Betaherpesvirinae.
 Rodents that belong to the betaherpesvirinae subfamily of herpesviruses serve as natural hosts.
 There are currently three species in this genus including the type species Murid herpesvirus 1.
 Diseases associated with this genus include: infected peritoneal macrophages, dendritic cells (DC) and hepatocytes, inducing significant pathology in both the spleen and the liver.
 Murid viruses murid herpesvirus 1 (MuHV-1) and murid herpesvirus 2 (MuHV-2)—previously defined as mouse cytomegalovirus (MCMV) and rat cytomegalovirus (RCMV)—belong to this genus.
Genoplesium commonly known as midge orchids, is a genus of about 50 species of flowering plants in the orchid family, Orchidaceae and is found in Australia, New Zealand and New Caledonia.
 Midge orchids are terrestrial herbs with a single leaf at the base of the plant.
 They are similar to orchids in the genus "Prasophyllum" in that plants without flowers have a hollow, onion-like leaf.
 The flowers are small but often scented and attractive to their insect pollinators.
 There is disagreement about which species belong to this genus and some taxonomists suggest that most belong in the genus "Corunastylis".
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.
Perovskia is a genus of flowering plants in the mint family, Lamiaceae.
 Members of the genus are native to southwestern and central Asia.
 It includes the garden plant Russian sage ("P. atriplicifolia").
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.
Toktokkies are a variety of species of beetles that belong to the large Tenebrionidae family, also known as Darkling beetle.
 Toktokkies do not belong to a particular tribe or genus of Tenebrionids, but rather a selection of flightless species with distinct tapping noises.
 The Tenebrionidae family to which these beetles belong is quite large, with almost 3,500 species inhabiting Southern Africa.
 Nearly 200 species of Toktokkies inhabit the country of Namibia and 20 have adapted to the extreme temperatures of the Namib Desert.
 The most common Toktokkies in the Namib Desert are the Fog Basking beetle ("Onymacris unguicularis") and the button beetle or trench-digging beetle ("Lepidochora discoidalis").
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".
Perovskia atriplicifolia ( ), commonly called Russian sage, is a flowering herbaceous perennial plant and subshrub.
 Although not a member of "Salvia", the genus of other plants commonly called sage, it is closely related to them.
 It has an upright habit, typically reaching 0.5 - , with square stems and grey-green leaves that yield a distinctive odor when crushed.
 It is best known for its flowers.
 Its flowering season extends from mid-summer to late October, with blue to violet blossoms arranged into showy, branched panicles.

Question:  Do  Eriophorum and Perovskia both belong to the same genus?
Answer: no
