Fungi named in 1934

Xeromphalina campanella is a species of mushroom. Its common names include the golden trumpet and the bell Omphalina. It is a cold-tolerant species found throughout North America and Eurasia.

Ophiostoma ulmi is a species of fungus in the family Ophiostomataceae. It is one of the causative agents of Dutch elm disease. It was first described under the name Graphium ulmi, and later transferred to the genus Ophiostoma. Dutch elm disease originated in Europe in the early 1900s. Elm trees were once an ecologically valuable tree that dominated mixed broadleaf forests, floodplains, and low areas near rivers and streams. They were planted in urban settings because of their aesthetic appeal and their ability to provide shade due to their V like shape. An outbreak of Dutch elm disease in the

Stropharia hornemannii, commonly known as the luxuriant ringstalk or lacerated stropharia, is a species of agaric fungus in the family Strophariaceae. The fungus produces distinctive mushrooms with caps up to 12 cm wide, which range from greyish-brown with purplish tints to reddish-brown, featuring a hanging ring on the stipe and gills that change from greyish-violet to dark purple-brown as they mature.

Xeromphalina is a genus of fungi in the family Mycenaceae. The genus has a widespread distribution, and contains about 30 species.

Macrocystidia cucumis is a common, inedible mushroom of the genus Macrocystidia, often found in large numbers on needle litter or moist soil.

Macrocystidia is a genus of fungus in the mushroom family Macrocystidiaceae. The genus contains five species that collectively have a widespread distribution.

Xeromphalina cauticinalis is a species of agaric fungus in the family Mycenaceae. Originally described in 1838 by Elias Fries as Marasmius cauticinalis, it was transferred to the genus Xeromphalina by Robert Kühner and René Maire in 1934. The fruit bodies have convex yellowish caps measuring 0.5–2.5 cm (1⁄4–1 in) in diameter supported by a tough yellow-brown to dark brown stipe that is 2.5–8 cm (1–3+1⁄8 in) long and 0.5–2.5 millimetres (1⁄32–3⁄32 in) thick. The pale yellow gills have a decurrent attachment to the stipe and are somewhat distantly spaced. The spore print is white, while

Pholiota malicola, commonly known as the forgettable pholiota, is an inedible species of fungus. The species is in the family Strophariaceae. Originally called Flammula malicola by mycologist Calvin Henry Kauffman in 1926, it was transferred to the genus Pholiota by Alexander H. Smith in 1934. It is an orangish species with a smooth cap 3–9 centimetres (1+1⁄4–3+1⁄2 in) in width. The stalk is 4–15 cm (1+1⁄2–6 in) long. It is found in North America and Australia. It grows in groups on decaying wood.

The fungal genus Cochliobolus includes 19 species, it includes some plant pathogenic species such as Cochliobolus heterostrophus. A lot of former Cochliobolus species were transferred to either Curvularia or Bipolaris genera. Cochliobolus heterostrophus is known from "southern corn blight" which affects corn and maize.

Aspergillus tubingensis is a darkly pigmented species of fungus in the genus Aspergillus section Nigri. It is often confused with Aspergillus niger due to their similar morphology and habitat. A. tubingensis is often involved in food spoilage of fruits and wheat, and industrial fermentation. This species is a rare agent of opportunistic infection.

The Ceratomycetaceae are a family of fungi in the order Laboulbeniales. Taxa have a widespread distribution, and are epibiotic or parasitic on insect cuticles.

The Trichosporonaceae are a family of fungi in the order Trichosporonales. The family currently contains six genera. Species are not known to produce basidiocarps (fruit bodies), but exist as yeasts or produce septate hyphae with arthroconidia. Several species are human pathogens.

Lentinellus vulpinus is a species of fungus belonging to the family Auriscalpiaceae. It has a cosmopolitan distribution. Like all species in its genus, it is inedible due to its bitterness.

Gloeopeniophorella is a genus of crust-like, wood-decaying fungi in the family Russulaceae. It contains six known species. Gloeopeniophorella was first described by Brazilian mycologist Johannes Rick in 1934. Hjortstam & Ryvarden (2007) wrote on Gloeopeniophorella: "The genus should be fairly easy to recognize with species having an almost smooth hymenophore, hyphae without clamp-connections, both metuloids and gloeocystidia, and spores that are both rugose and amyloid. We are of the opinion that the dextrinoid reaction of the metuloids in Dextrinocystidium is not an important character for

Carex uncinata, the Hawai'i birdcatching sedge, hook grass, hook sedge, bastard grass, kamu or matau-a-maui, is a species of flowering plant in the sedge family, Cyperaceae. Carex uncinata is native to New Zealand (including the Antipodes), the Society Islands, and Hawaii. Its natural habitat is from the coast up to 1,000 m (3,300 ft), where it is found in areas ranging from native forest to shrubland.

Triangularia is a genus of fungi in the family Podosporaceae.

Sirobasidium magnum is a species of fungus in the order Tremellales. Basidiocarps (fruit bodies) are gelatinous, lobed to foliose (leaf-like) and appear to be parasitic on ascomycetous fungi on wood. No other Sirobasidium species has such large fruit bodies. The species was originally described from Indonesia, but has been reported from elsewhere in Asia and also in Australia and North America.

Dermatocarpon arnoldianum, also known vernacularly as Arnold's silverskin lichen, is a species of lichen belonging to the family Verrucariaceae. Part of the genus Dermatocarpon, it has been found in Great Britain, Ireland, Austria, Bulgaria and France.

Cochliobolus heterostrophus is a fungal plant pathogen. It can cause southern corn leaf blight in maize. Cochliobolus heterostrophus is found in many tropical regions and in the southern part of the US. Cochliobolus, although not currently the most economically serious disease, can be a very serious crop disease. C. heterostrophus (race O) was considered a mild pathogen of corn, and was of little worry to those growing maize crops. It was not until the 1970s that C. heterostrophus (race T) destroyed more than 15% of the U.S. corn crop. Race T differed from race O in the sense that it produced

Cejpia is a genus of fungi in the family Dermateaceae. The genus, named in honour of Czech mycologist Karel Cejp, contains two species. The genus was circumscribed by Josef Velenovsky in Monogr. Discom. Bohem. on page 125 in 1934.

Biatoropsis usnearum is a species of parasitic fungus that grows exclusively on lichen species of the genus Usnea, particularly U. subfloridana, U. barbata, and U. florida. First described in 1934 by Veli Räsänen, it has become a significant model organism in fungal evolution studies due to its specialised host relationships. The fungus belongs to the order Tremellales, though its precise family classification remains uncertain. It forms distinctive swellings or galls on its host lichens, ranging in colour from pale pink to dark reddish-brown, and notably suppresses the production of host

Aspergillus unguis is a species of fungus in the genus Aspergillus, and the asexual state (anamorph) of Emericella unguis. Aspergillus unguis is a filamentous soil-borne fungus found on decomposing plant matter and other moist substrates including with building materials and household dust. Aspergillus unguis occurs mainly in tropical and subtropical soils but has also been isolated from various marine and aquatic habitats. The species was first isolated in 1935 by Weill and L. Gaudin. Historically, A. unguis was assigned to the A. nidulans group, a common group of soil-borne fungi due to the
