Fungi named in 1940

Cortinarius trivialis is a species of inedible fungus in the genus Cortinarius. The mushroom cap is 3–12 cm (1.2–4.7 in) wide, grayish blue then yellow-brown, convex to flat, perhaps with a mild umbo. The gills are adnate or adnexed, grayish blue turning brown as the spores mature. The stalk is 5–15 cm (2–6 in) tall and 1–2 cm wide, equal or tapered, white to yellow, with whitish partial veil on the upper stalk (becoming brown with the spores). It was reported as edible as recently as 1991, but European field guides consider it poisonous. For many species of Cortinarius edibility is unknown,

Catathelasma imperiale, also known as Catathelasma imperialis, and commonly known as the imperial mushroom, Hutsul mushroom, or korban, is a species of agaric (gilled mushroom) in the family Biannulariaceae. Basidiocarps (fruit bodies) are stocky, with a double annulus (ring), and a tapering to rooting stipe (stem). The species is ectomycorrhizal with conifers and is found in continental Europe and Asia. Reports from North America are unconfirmed and may refer to Catathelasma evanescens or similar species. The fruit bodies are edible and collected for food in China and elsewhere. The species

Lepiota subincarnata, commonly known as the fatal dapperling and deadly parasol, is a gilled mushroom of the genus Lepiota in the order Agaricales. It was first described scientifically by the Danish mycologist Jakob Emanuel Lange in 1940. Bon and Boiffard described Lepiota josserandii in 1974, which turned out to be the same species. The mushroom's cap is light red to red-brown and cream-colored closer to the margin. The gills are whitish and the flesh is white to pinkish towards the top. The stem may be slightly larger at the base, cream-colored with patches of the cap color. The odor is

Brettanomyces is a non-spore forming genus of yeast in the family Pichiaceae, and is often colloquially referred to as "Brett". The genus name Dekkera is used interchangeably with Brettanomyces, as it describes the teleomorph or spore forming form of the yeast, but is considered deprecated under the one fungus, one name change. The cellular morphology of the yeast can vary from ovoid to long "sausage" shaped cells. The yeast is acidogenic, and when grown on glucose rich media under aerobic conditions, produces large amounts of acetic acid. Brettanomyces is important to both the brewing and

Bondarzewia is a widely distributed genus of fungi in the family Bondarzewiaceae. The genus was circumscribed by mycologist Rolf Singer in 1940.

Russula firmula is a species of mushroom found in Europe and parts of Asia that has dark red-purple to red-brown cap. It is one of about 750 species in the genus Russula, which is distributed worldwide. Together with R. rubra, R. rutila and R. veternos, it was placed in the Rubrinae clade in 2017.

Hebeloma pusillum is a species of mushroom in the family Hymenogastraceae. It is found in Europe.

Amanita cokeri, commonly known as Coker's amanita and solitary lepidella, is a poisonous mushroom in the family Amanitaceae. First described as Lepidella cokeri in 1928, it was transferred to the genus Amanita in 1940.

Lepiota fuscovinacea is a species of fungus belonging to the family Agaricaceae. It is native to Europe and Northern America.

Dictyocephalos is a genus of fungi in the family Phelloriniaceae of the order Agaricales. The genus is monotypic, and contains the single species Dictyocephalos attenuatus, commonly known as the stalked oddball, which was described by the American botanist Lucien Marcus Underwood in 1901 (as D. curvatus). Dictyocephalos attenuatus is a unique species of mushroom, as it has a gleba like a puffball, but it also has a stipe and a volva, like an Amanita. Starting as an underground "egg", the spore case develops up to 13 cm (5 in) across, round and slightly gelatinous at first then flattens and

Ovulinia is a genus of fungi in the family Sclerotiniaceae.

Lactarius paradoxus is a North American member of the large milk-cap genus, Lactarius, in the order Russulales. The mushroom is blue-green to gray, staining green and bleeding red latex. It is edible but becomes bitter with age.

Haematomma accolens, commonly known as the tree bloodspot, is a species of crustose lichen in the family Haematommataceae. It forms thin to moderately thick patches on tree bark, appearing yellowish-white to greenish-grey in colour, and features vivid red to deep reddish-orange spore-producing structures (apothecia). The lichen typically grows on the bark of deciduous trees in warm-temperate and subtropical regions, particularly favouring smooth-barked trees such as oaks and maples in shaded forest environments. Since its description by the Scottish botanist James Stirton in 1881, it has been

Sarcodon stereosarcinon is a species of tooth fungus in the family Bankeraceae. Found in North America, it was described as new to science in 1940 by mycologist Lewis Edgar Wehmeyer, who found the original collections in Nova Scotia, Canada.

Phialophora cinerescens is an ascomycete fungus that is a plant pathogen infecting carnations.

Penicillium novae-zelandiae is an anamorph species of fungus in the genus Penicillium which was isolated from the plant Festuca novae-zelandiae. Penicillium novae-zelandiae produces patulin, 3-hydroxybenzyl alcohol and gentisyl alcohol

Typhula ishikariensis is, along with Typhula incarnata, the causal agent of grey snow mould (also called speckled snow mould or Typhula blight), an obligately parasitic plant pathogen that can destroy turfgrass when covered for a long period with snow. It is a particular problem on golf courses established in unsuitable areas. More importantly, it can also damage crops of winter wheat. The species was described as new to science in 1930 by Japanese mycologist Sanshi Imai. The varieties canadensis and ishikariensis (the former as a new combination) were described in 1978. There is a wide
