Fungi named in 1905

Agaricus abruptibulbus is a species of fungus in the genus Agaricus. It is commonly known as the abruptly-bulbous agaricus or the flat-bulb mushroom. First described by mycologist Charles Horton Peck, the mushroom is medium-sized, with a white, yellow-staining cap on a slender stipe which is bulbous on the base. The species smells slightly of anise and turns yellow when bruised or cut.

Rigidoporus is a genus of fungi in the family Meripilaceae. Many of the species in this genus are plant pathogens. The widespread genus, which contains about forty species, was originally circumscribed by American mycologist William Alphonso Murrill in 1905. The generic name combines the Latin word rigidus ("rigid") with the Ancient Greek word πόρος ("pore").

Rhizoplaca is a genus of lichenized fungi in the family Lecanoraceae. Members of the genus are commonly called rimmed navel lichens because of their umbilicate growth form and lecanorine (rimmed with thallus-like tissue)apothecia, also rock-posy lichen and rockbright.

Cryphonectria is a fungal genus in the order Diaporthales. The most well-known and well-studied species in the genus is Cryphonectria parasitica, the species which causes chestnut blight. The genus was, for a time, considered synonymous with Endothia, but the two are now recognised as distinct. Taxonomic studies in 2006 limited the genus to four species, but a fifth, Cryphonectria naterciae, was described in 2011 from Portugal.

Coriolopsis is a genus of fungi in the family Polyporaceae. It was circumscribed by American mycologist William Alphonso Murrill in 1905. The genus is cosmopolitan, with most species in tropical areas. The generic name combines the name Coriolus with the Ancient Greek word ὄψις ("appearance").

Chrysotrichaceae is a family of lichenized fungi in the order Arthoniales. Member of this family have a widespread distribution, but are especially prevalent in tropical areas. "Chrysothrichaceae" and "Chrysothricaceae" are alternative spellings that have been used in some older publications; the latter was used by Alexander Zahlbruckner in the protologue publication. Both of these spellings are considered incorrect, and the current spelling has been formalised following a proposal for conservation of Chrysotrichaceae against Pulverariaceae (an earlier synonym).

Aurantiporus is a genus of poroid fungi in the family Meruliaceae. Circumscribed by American mycologist William Alphonso Murrill in 1905, the genus contains five species found mostly in northern temperate regions. Molecular analysis of several Aurantiporus species suggests that the genus is not monophyletic, but some other related polypore species need to be sequenced and studied before appropriate taxonomic changes can be made. In 2018, Viktor Papp and Bálint Dima proposed a new genus Odoria to contain Aurantiporus alborubescens based on multigene phylogenetic analyses. The generic name is

Pycnoporellus is a genus of fungi in the family Fomitopsidaceae. The widespread genus, circumscribed by American mycologist William Alphonso Murrill in 1905, contains two species.

Porodaedalea pini, commonly known as the pine conk or pine bracket, is a species of fungus in the family Hymenochaetaceae. It is a plant pathogen that causes tree disease commonly known as "red ring rot" or "white speck". This disease, extremely common in the conifers of North America, decays tree trunks, rendering them useless for lumber. It is a rot of the heartwood. Signs of the fungus include shelf-shaped conks protruding from the trunks of trees. Spores produced on these conks are blown by the wind and infect other trees. Formal management of this disease is limited, and the disease is

Porodaedalea is a genus of fungi in the family Hymenochaetaceae. The genus was circumscribed by American mycologist William Alphonso Murrill in 1905.

Flaviporus is a genus of poroid fungi in the family Steccherinaceae.

Amauroderma is a genus of polypore fungi in the family Ganodermataceae. The genus, widespread in tropical areas, contains about 70 species. Amauroderma fungi are wood-decay fungi that feed and fruit on decayed branches and trunks. The fruit bodies of Amauroderma fungi comprise a cap and a stipe, and are typically woody, leathery, or corky in texture. The spores produced are usually spherical or nearly so, with a characteristic double wall structure that features U-shaped thickenings.

The Ectolechiaceae are a family of lichen-forming fungi in the order Lecanorales. The species of this family have a cosmopolitan distribution and have been found in a variety of climatic regions. The family was first described by Alexander Zahlbruckner in 1905, originally for a group of tropical, leaf-dwelling lichens. Its scope has since expanded considerably, and the family now encompasses both tropical genera such as Byssoloma and Calopadia and the large, predominantly temperate-to-arctic genus Micarea. As of 2026, the family contains more than 30 genera and an estimated 470 species. It

Corynespora is a fungus genus. It is a member of the mitosporic Ascomycota, a heterogeneous group of ascomycotic fungi whose common characteristic is the absence of a sexual state. Species in the genus induce Corynespora leaf spot in bleeding hearts (Clerodendrum thomsoniae).

Tricholoma sulphurescens is a mushroom of the agaric genus Tricholoma. It was first formally described by Italian mycologist Giacomo Bresadola in 1905. It is found in Europe and northeastern North America.

The Schizosaccharomycetaceae are a family of yeasts in the order Schizosaccharomycetales.

Phragmidium rosae-pimpinellifoliae is a species of fungus in the family Phragmidiaceae. A plant pathogen, it causes a rust on the stem, leaves, petioles and fruits of burnet rose and related hybrids. The fungus is found in Europe and North America.

Fomitella is a genus of fungi in the family Fomitopsidaceae. The genus was described in 1905 by American mycologist William Alphonso Murrill with F. supina as the type species.

Uromycladium is a genus of rust fungi in the family Pileolariaceae. It was circumscribed by mycologist Daniel McAlpine in 1905. The genus was established by McAlpine for rusts on Acacia (Fabaceae, subfamily Mimosoideae) with teliospores that clustered at the top of a pedicel. The genus contains at least 11 species. Some of these species infect plants in the family Mimosoideae including Acacia, Paraserianthes and Falcataria. Most species are considered to be specific to only one host species of plant, such as Uromycladium simplex on Acacia pycnantha and Uromycladium falcatarium on Falcataria

Nigroporus vinosus is a species of poroid fungus in the family Steccherinaceae, and the type species of the genus Nigroporus. Its fruit bodies have brownish caps with tinges of purple or red. The cap underside has a pore surface the same colour as the cap, and minute pores. The species is a wood-decay fungus that causes a white rot. It has a pantropical distribution, being found in Asia, Africa, Oceania, and the Americas.

Cunninghamella echinulata is a fungal species in the genus Cunninghamella. It is an asexually reproducing fungus and a mesophile, preferring intermediate temperature ranges. C. echinulata is a common air contaminant, and is currently of interest to the biotechnology industry due to its ability to synthesize γ-linolenic acid as well as its capacity to bioconcentrate metals. This species is a soil saprotroph that forms rhizoids, preferring soils enriched in nitrogen, phosphorus and potassium. It has been reported occasionally an agent of mucormycosis following the inhalation of fungal spores.

The Coccoideaceae are a family of fungi with an uncertain taxonomic placement in the class Dothideomycetes. The Family Coccoideaceae includes the following: Genera: Coccodiscus Coccodothella Coccoidea Coccoidella Dianesea

Unguicularia is a genus of fungi within the Hyaloscyphaceae family. The genus contains seven species.

Rhizoplaca chrysoleuca (orange rim lichen, rock-posy lichen, rockbright) is a pale yellowish-green to gray-green umbilicate foiliose lichen in the Lecanoraceae (rim lichen) family. It was first described in 1791 by English botanist Sir James Edward Smith as Lichen chrysoleucus; Friedrich Wilhelm Zopf transferred it to the genus Rhizoplaca in 1905. The single-leaf (monophyllous) umbilicate thallus can be 2–3.5 cm in width, with deep lobes. The thallus is relatively thick and lumpy with warts and lobules. The fruiting structures (apothecia have lightly pruinose, burnt-orange to tan discs
