Henri François Anne de Roussel

French naturalist (1748-1812).

Henri François Anne de Roussel (11 July 1748 in Saint-Bômer-les-Forges – 17 February 1812 in Caen) was a French naturalist. He studied humanities and philosophy at the University of Caen, obtaining the rank of "maître ès-arts" in 1767. Afterwards he studied medicine in Caen, relocating to Paris in 1771, where he furthered his education. In 1773 he was appointed to the chair of medicine at Caen, where in 1786, he attained the chair of medical botany. Later on, he served as a professor of experimental physics and chemistry at the École centrale du Calvados.

Suillus luteus (Slippery Jack) (L.) Roussel 1796
edible fungi species in the suillaceae family
Suillus luteus is a species of bolete fungus commonly referred to as slippery jack or sticky bun. The fungus was originally assigned to Boletus by Carl Linnaeus in 1753, before being made the type species of Suillus in 1796. The slimy cap is typically up to 10 cm (4 in) wide and conical before flattening. A membranous partial veil connects the cap to the stem when young. Yellow tubes extend downward from the underside of the cap, which spores escape through. The pale stem is up to 10 cm (4 in) tall and 3 cm (1+1⁄4 in) thick, bearing small dots near the top. Unlike most other boletes, it bears
Suillus bovinus (Jersey Cow Mushroom) (L.) Roussel 1796
edible fungi species in the suillaceae family
Suillus bovinus, also known as the Jersey cow mushroom or bovine bolete, is a pored mushroom of the genus Suillus in the family Suillaceae. It was initially described as Boletus bovinus by Carl Linnaeus in 1753, and given its current binomial name by Henri François Anne de Roussel in 1806. Suillus bovinus produces spore-bearing fruit bodies, often in large numbers, above ground. The mushroom has a convex grey-yellow or ochre cap reaching up to 10 cm (4 in) in diameter, which flattens with age. Like other boletes, it has tubes extending downward from the underside of the cap, rather than
Suillus granulatus (Weeping Bolete) (L.) Roussel 1796
edible fungi species in the suillaceae family
Suillus granulatus is a species of fungus in the genus Suillus. It has been commonly known as the weeping bolete or the granulated bolete. It is a pored mushroom similar to S. luteus, but can be distinguished by its ringless stalk. The species often grows in a symbiosis (mycorrhiza) with pine. It is native to the Northern Hemisphere and has been introduced elsewhere. It is edible.
Mycena (Bonnets) (Pers.) Roussel 1806
fungi genus in the mycenaceae family
Mycena is a genus of about 500 species of fungi. Rarely more than a few centimeters in width, the mushrooms are characterized by a small conical or bell-shaped cap and a thin fragile stem. Most are grey or brown, but a few species have brighter colours. Most have a translucent and striate cap, which rarely has an incurved margin. The gills are attached and usually have cystidia. Some species, like M. haematopus, exude a latex when the stem is broken, and many species have a chlorine or radish-like odour. They produce a white spore print. The species are saprotrophic. Their edibility varies,
Ustilago (Pers.) Roussel 1806
fungi genus in the ustilaginaceae family
Ustilago is a genus of approximately 200 smut fungi, which are parasitic on grasses. 170 species are accepted by Wijayawardene et al. 2020; After phylogenetic research certain species in Ustilago, Macalpinomyces, and other genera in the Ustilaginaceae clade have been moved to other genera such as Mycosarcoma.
Suillus viscidus (Sticky Bolete) (L.) Roussel 1796
edible fungi species in the suillaceae family
Suillus viscidus (commonly known as the sticky bolete) is an edible, uncommon mushroom in the genus Suillus. It associates with larch and is found throughout Europe and in Japan.
Albugo (Pers.) Roussel 1806
fungi genus in the albuginaceae family
Albugo is a genus of plant-parasitic oomycetes. Those are not true fungi (Eumycota), although many discussions of this organism still treat it as a fungus. The taxonomy of this genus is incomplete, but several species are plant pathogens. Albugo is one of three genera currently described in the family Albuginaceae, the taxonomy of many species is still in flux. This organism causes white rust or white blister diseases in above-ground plant tissues. While these organisms affect many types of plants, the destructive aspect of infection is limited to a few agricultural crops, including: beets
Albugo candida (Pers. ex J.F. Gmel.) Roussel 1806
fungi species in the albuginaceae family
Albugo candida, commonly known as white rust or white blister rust, is an obligate plant pathogen in the family Albuginaceae that infects Brassicaceae species. (Although called a "rust" and a fungus, it is an oomycete.) It has a relatively smaller genome than other oomycetes.
Lactifluus (Pers.) Roussel 1806
fungi genus in the russulaceae family
Lactifluus is one of three genera of mushroom-forming fungi containing species commonly named "milk-caps", the others being Lactarius and Multifurca. It has been separated from Lactarius based on molecular phylogenetic evidence but is very similar to that genus. There are roughly 150 known Lactifluus species, which have a mainly tropical distribution but are also found in the north temperate zone and Australasia. Some of them are edible mushrooms.
