Volvopluteus gloiocephalus, commonly known as the big sheath mushroom, rose-gilled grisette, or stubble rosegill, is a species of mushroom in the family Pluteaceae. For most of the 20th century it has been known under the names Volvariella gloiocephala or V. speciosa, but recent molecular studies have placed it as the type species of the genus Volvopluteus, newly created in 2011. The cap of the mushroom is about 5–15 cm (2–6 in) in diameter, varies from white to grey or grey-brown, and is markedly sticky when fresh. The gills start out as white but they soon turn pink. The stipe is white and

Volvopluteus is a genus of small to medium-sized or big saprotrophic mushrooms growing worldwide. The genus has been segregated from Volvariella with which it shares some morphological characteristics such as the presence of a volva and a pink to pink-brown spore print. Phylogenetic analyses of DNA data have shown that Volvopluteus is closely related to Pluteus and both genera currently are classified in the family Pluteaceae, while Volvariella is not closely related to either genus and its position in the Agaricales is still uncertain.

Tricholosporum tetragonosporum is a species of fungus in the family Tricholomataceae. Found in Morocco, the species was first described as Tricholoma tetragonosporum by René Maire in 1945, and transferred into Tricholosporum in 2000.

Saproamanita thiersii (formerly Amanita thiersii), commonly called Thiers' lepidella, is a North American saprotrophic basidiomycete fungus in the genus Saproamanita. It is a white, small mushroom. Its cap is convex, measuring 3.5–10 centimetres (1+1⁄2–4 inches) across, and the stipe is 8–20 cm (3–8 in) long. The spore print is white. Originally described from Texas but today found in ten states of North America, the mushroom grows in lawns, pastures and prairies. It is a saprotroph, living on decaying plant material, and not mycorrhizal as is the case with species of Amanita, where it was

The genus Saproamanita contains about 24 species of agarics and is one of six genera in the family Amanitaceae, of which the similar Amanita is also a member. Saproamanita differs from Amanita in that its species are saprophytic, and not ectomycorrhizal.

Gymnopilus maritimus is a fungus species of the family Hymenogastraceae first collected in northern Sardinia, Italy, in 2006. The species produces moderately sized, sturdy mushrooms of a reddish-orange colour. The cap, which can measure up to 70 millimetres (3 in) across, is covered in orange fibrils, and sometimes has small scales. The yellowish stem measures up to 110 mm (4 in) in length by 8 mm (0.3 in) in width, and sometimes shows remnants of the partial veil. The mushrooms have thick gills of a variable colour, ranging from yellow to rust but staining darker, and the yellow flesh has a

Volvopluteus earlei is a species of mushroom in the family Pluteaceae. It was originally described in 1911 by American mycologist William Alphonso Murrill as Volvariopsis earlei, based on collections made in a Cuban banana field. The fungus was later shuffled to the genera Volvaria and Volvariella before molecular studies placed it in Volvopluteus, a genus newly described in 2011. The cap of Volvopluteus earlei is typically between 2.5–5 cm (1–2 in) in diameter, white, and is markedly viscid when fresh. The gills start out as white but they soon turn pink. The stipe is white and measures 5 cm

Romagnesiella is an agaric fungal genus that colonizes mineral, calcareous or sandy soils in Europe and North Africa. The small brownish fruitbodies have narrowly attached, broad and distant lamellae and poorly differentiated cheilocystidia and pleurocystidia. Spores are thick-walled, brown, smooth, and lack germ pore. The cap surface (pileipellis) is somewhat cellular with irregular puzzle-like to pyriform hyphae. Clamp connections are present in the hyphae. It is most closely related to Crassisporium, both genera being close to the Strophariaceae or the Cortinariaceae.

Saproamanita inopinata, commonly called unexpected amanita, is a basidomycete fungus in the subgenus Saproamanita. This species was previously called Amanita inopinata, before being briefly renamed to Aspidella inopinata until it received its current name. The native range is currently unknown, with it currently being considered introduced into both New Zealand and England.

Musumecia is a genus of fungi in the order Agaricales. Basidiocarps (fruit bodies) are agaricoid and resemble those of Clitocybe species. The genus is currently known from Europe and China.

Clitocybe cistophila is a species of agaric fungus in the family Tricholomataceae, formally described in 1985 based on collections from Sardinia, Italy. The fungus produces small fruiting bodies with milk-white to cream caps that become funnel-shaped with age, and emit a distinctive anise odour when fresh. It grows exclusively in maquis shrubland habitats on sandy, acidic soils beneath rockrose shrubs (Cistus species), particularly in association with holm oak, maritime pine, myrtle, and bay laurel. Initially known only from southern Sardinia, the species has since been found in Tuscany and
