Fungi named in 1854

Puccinia striiformis is a fungal species and plant pathogen. It causes stripe rust on wheat, but has other hosts as well. The species is common in Europe and in more recent years has become a problem in Australia. Crop infections can cause losses of up to 40%, and the fungus will infect both winter wheat and spring wheat.

Menegazzia terebrata is a species of foliose lichen found scattered across many continents, including North America, South America, Europe, Africa, and Asia.

Coleosporium tussilaginis is a species of rust fungus in the family Coleosporiaceae. It is a plant pathogen. It is known to infect Campanula rotundifolia, on which it produces urediniospores and teliospores.

Menegazzia is a genus of lichenized fungi containing roughly 70 accepted species. The group is sometimes referred to as the tree flutes, honeycombed lichens, or hole-punch lichens. The most obvious morphological feature of the genus is the distinctive perforations spread across the upper side of the thallus. This makes the group easy to recognise, even for those not particularly familiar with lichen identification. The genus has a sub-cosmopolitan distribution (excluding Antarctica), but is concentrated in Australasia, Melanesia, and southern South America. Most species grow exclusively on

Sporastatia is a genus of crustose lichens in the family Sporastatiaceae. It has four species. Sporastatia lichens are long-lived species that grow on siliceous or weakly calcareous rocks in arctic and alpine locales.

Ophiobolus is a genus of fungi in the family Phaeosphaeriaceae.

Acrocordia is a genus of lichen-forming fungi in the family Monoblastiaceae. These lichens form thin, whitish to pale grey crusts on tree bark and rocks, appearing as scattered black dots where their tiny flask-shaped reproductive structures emerge from the surface. The genus includes nine species found in various parts of the world, typically growing in mildly alkaline environments on broad-leaved trees or damp, mineral-rich rock faces.

Sagiolechia is a genus of lichen-forming fungi in the family Sagiolechiaceae. These lichens form either extremely thin crusts within their substrate or live parasitically on other lichens without forming their own thallus. The genus is characterised by distinctive black, glossy fruiting bodies that begin embedded within the host material and later erupt to the surface, often developing elaborate folded or star-like forms. Sagiolechia contains six species found in diverse locations including Alaska, Greenland, Norway, and Madeira, with most species being quite rare and relatively recently

Stegocintractia junci is a species of fungus in the family Anthracoideaceae. It is a plant pathogen infecting sunflowers.

The Myriangiaceae are a family of fungi in the Ascomycota, class Dothideomycetes. Species in this family have a widespread distribution (and are especially prevalent in tropical areas), and are typically found associated with scale insects. The family occupies an isolated phylogenetic position within the Dothideomycetes.

Hygrophorus mesotephrus is a species of fungus in the genus Hygrophorus.

Heppia is a genus of olive, brownish, grey, or blackish squamulose, crustose, or peltate like lichens. Heppia was once the type genus of the family Heppiaceae, but that family was folded into synonymy with Lichinaceae. In a multilocus phylogeny and re-classification of the class Lichinomycetes published in 2024, María Prieto, Mats Wedin and Matthias Schultz placed Heppia in the family Porocyphaceae as part of an emended, broader circumscription of that family; earlier treatments that folded Heppiaceae into Lichinaceae are therefore superseded by the new arrangement. Species of Heppia are

Dyplolabia afzelii is a species of corticolous (bark-dwelling), script lichen in the family Graphidaceae. It has a pantropical distribution. The lichen has a thallus with colours ranging from yellow to pale olive buff, dark brownish tan, or grey, characterised by its smooth texture and considerable thickness. Its ascomata are lirelline (elongated with a slit-like opening), often raised from the thallus surface and concealed under a powdery white layer.

Berkleasmium is a genus of fungi belonging to the family Dematiaceae. The genus name of Berkleasmium is in honour of 2 people (Berkley and Lea), Miles Joseph Berkeley (1803 - 1889), an English cryptogamist and clergyman, and one of the founders of the science of plant pathology and also Thomas Gibson Lea (1785–1844), who was an American botanist. The genus was circumscribed by Johann Baptista Zobel in Icon. (Corda) vol.6 n page 4 in 1854.

Acrocordia gemmata is a species of lichen belonging to the family Monoblastiaceae. Acrocordia gemmata is characterised by a thin, crustose thallus that ranges in colour from white to pale gray or green, with no hypothallus visible. The perithecia are hemispherical, black and somewhat immersed in the thallus, with an ostiole at the top and long-celled pseudoparaphyses. The asci are narrowly cylindrical, and have an apical dome with a broad ocular chamber, covered by a hemispherical meniscus-like structure. The asci contain 8 ellipsoid ascopores each (18-30 x 8-12 μm), which are 1-septate and

Septoria humuli is a fungal plant pathogen infecting the hop plant.

Physma is a genus of cyanolichens in the family Pannariaceae. It has five species. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1854, with Physma boryanum assigned as the type species.

Nectria pseudotrichia is an ascomycete plant pathogen, of which the orange-coloured fruiting bodies are just visible to the naked eye.

Mazosia is a genus of lichen-forming fungi in the family Roccellaceae.

Entodesmium is a genus of fungi in the family Lophiostomataceae.

Dyplolabia is a genus of lichen-forming fungi in the family Graphidaceae. These lichens form smooth, rather thick grey-yellow to olive-buff crusts on tree bark and are characterized by narrow, elongate fruiting bodies that are commonly hidden beneath a conspicuous white powdery coating. The genus has a pantropical distribution, growing on the smooth bark of trees and shrubs in both shaded rainforest understories and moderately exposed coastal woodlands, where they serve as indicators of long-established woodland habitat.

Dasyspora is a genus of rust fungi in the family Uropyxidaceae.

Cantharellus guyanensis is a tropical South American species of mushroom-forming fungus in the chanterelle genus (Cantharellus), first described by Camille Montagne from French Guiana in 1854. It has since also been found in Guyana, Suriname, Venezuela, and Brazil. The fruit bodies have a bright orange cap colour and occur in medium- to large-sized troops. C. guyanensis seems to prefer sand-rich soil and forms ectomycorrhiza with a putatively wide range of host trees and shrubs including Coccoloba, Guapira, and Neea. Its congeners Cantharellus aurantioconspicuus, C. amazonensis, and C.
