Fungi named in 1933

Clavariadelphus pistillaris, commonly known as the common club coral, is a rare species of mushroom of the family Gomphaceae native to Europe and North America.

Panaeolus foenisecii, commonly called the haymaker's panaeolus, lawnmower's mushroom, mower's mushroom, haymaker, or brown hay mushroom, is a very common and widely distributed little brown mushroom often found on lawns. It is not edible.

Pholiota microspora, commonly known as Pholiota nameko or simply nameko (ナメコ), is a small, amber-brown mushroom with a slightly gelatinous coating that is used as an ingredient in miso soup and nabemono. In some countries this mushroom is available in kit form and can be grown at home. It is one of Japan's most popular cultivated mushrooms, tastes slightly nutty and is often used in stir-fries. They are also sold dried. Nameko is a cold triggered mushroom that typically fruits in the fall months when the temperature drops below 10°C for the first time, and flushes twice a few weeks apart. In

Clavariadelphus truncatus, commonly known as the truncate club coral, truncated club, or club coral, is a species of mushroom. It is a member of the basidiomycete fungi family Gomphaceae.

Tricholoma populinum, commonly known as the poplar tricholoma, sandy, or cottonwood mushroom, is a mushroom of the agaric genus Tricholoma.

Phellinus pomaceus is a plant pathogen particularly common on Prunus species. It is not aggressively pathogenic but can cause considerable decay in trees suffering from other stress factors. P. pomaceus is found in Europe as well as areas of Asia, South America and Africa. This species has historically been used for medicinal purposes and is currently being researched for its chemical and biological properties. This is a very long-lived conk, bearing as many as eighty annual growth rings.

Xerula is a genus of gilled mushrooms in the family Physalacriaceae.

Clavariadelphus ligula, commonly known as the strap coral, is a species of fungus in the family Gomphaceae. It produces club-shaped fruit bodies with spongy flesh that grow in groups on the forest floor. It is found in Eurasia and North America.

Zhuliangomyces illinitus is a mushroom-forming fungus species of genus Zhuliangomyces in the family Amanitaceae in the order Agaricales. It has recently been known as Limacella illinita, and previously as Agaricus illinitus and Mastocephalus illinitus. The fungus is known for its distinctive slimy cap, for which it is commonly known as the dripping slimecap or the overflowing slimy stem. As L. illinita, it was commonly known as the white limacella.

Hapalopilus croceus is a species of polypore fungus. It was originally described by Christian Hendrik Persoon in 1796 as Boletus croceus; Marinus Anton Donk transferred it to the genus Hapalopilus in 1933 to give it the name by which it is currently known. The species is found in Asia, Europe, Oceania, and North America, where it grows on the rotting wood of deciduous trees.

Clavariadelphus is a genus of fungi in the family Clavariadelphaceae in the order Gomphales. Morphologically its members can be described as club fungi with simple, erect and unbranched basidiomata, even if the clavarioid fungi are today not seen as a systematic group. Numbers of described and currently accepted species are constantly rising, this might be connected both to applied new techniques and due to previously understudied areas like China. As of March 2026 there are, depending on the source, either 31, 34 or 35 accepted species currently recognized.

Ceriporia is a widely distributed genus of crust fungi.

Clavulina amethystina is a species of coral fungus in the family Clavulinaceae.

Oxyporus populinus, also known as the mossy maple polypore and poplar bracket, is a species of fungus in the family Schizoporaceae. It is a plant pathogen that affects trees. It is typically white (sometimes gray near the center and/or pinkish near the margin), more or less semicircular, and 2.5–20 centimetres (1–8 in) wide, with tough flesh, which is inedible.

Oxyporus is a genus of polypore fungi in the family Schizoporaceae. An individual family Oxyporaceae was described for the genus. A number of species in this genus are plant pathogens, causing a white rot. The genus is widely distributed.

Gloeostereum is a genus of fungi in the family Cyphellaceae. This is a monotypic genus, containing the single species Gloeostereum incarnatum, an edible mushroom native to China. In Chinese culture, it is called yú'ěr (榆 耳; literally "elm ear"). It is sometimes included in a vegetarian dish called Buddha's delight.

Amanita subjunquillea, also known as the East Asian death cap is a mushroom of the large genus Amanita, which occurs in East and Southeast Asia. Potentially deadly if ingested, it is closely related to the death cap A. phalloides. Initially little reported, the toxicity of A. subjunquillea has been well established; a study in Korea revealed it to have similar effects to A. phalloides, namely delayed gastrointestinal symptoms, hepatotoxicity, and a 12.5% mortality. The species killed five people out of six who ingested them in Hebei, China, in 1994. An all-white variety, Amanita subjunquillea

Alternaria tenuissima is a saprophytic fungus and opportunistic plant pathogen. It is cosmopolitan in distribution, and can colonize a wide range of plant hosts. Colonies of A. tenuissima produce chains on agar growth media. The fungus often forms concentric ring patterns on infected plant leaves. This species produces the allergen Alt a 1, one of the most important outdoor seasonal fungal allergens associated with allergy and asthma provocation. In rare circumstances, this species is also known to infect immunosuppressed humans and animals.

Panaeolina is a small genus of small mushrooms, containing only about four species. They are a subgroup of Panaeolus which have dark brown spores. The type species is Panaeolina foenisecii, a common lawn mushroom. Members of Panaeolina are broadly distributed throughout the world. Some members of Panaeolina have been reported to contain the hallucinogen psilocybin, however these results are thought to be false positives. These fungi are sometimes classified as part of the genus Panaeolus. Like that genus their gills have a cloudy/speckled/mottled appearance due to the way that their spores

Curvularia is a genus of hyphomycete (mold) fungi which can be pathogens but also act as beneficial partners of many plant species. They are common in soil. Most Curvularia species are found in tropical regions, though a few are found in temperate zones. Curvularia is defined by the type species C. lunata (Wakker) Boedijn. Curvularia lunata appears as shiny velvety-black, fluffy growth (on the fungus colony surface). These fluffy 'hairs', which really are branching, fine filamentous structures called hyphae, are divided inside by cell walls named septae (-> the hyphae are 'septate'). The

Cumminsiella is a genus of fungi belonging to the family Pucciniaceae. The species of this genus are found in Europe, Northern America and Australia.

Aspergillus sclerotiorum is a species of fungus in the genus Aspergillus. It is from the Circumdati section. The species was first described in 1933. A. sclerotiorum has been reported to produce penicillic acid, xanthomegnin, viomellein, and vioxanthin. In 2016, the genome of A. sclerotiorum was sequenced as part of the Aspergillus whole-genome sequencing project - a project dedicated to performing whole-genome sequencing of all members of the genus Aspergillus. The genome assembly size was 37.97 Mbp.
