Fungi named in 1909

Suillellus luridus (formerly Boletus luridus), commonly known as the lurid bolete, is a fungus of the family Boletaceae, found in calcareous broadleaved woodlands in Europe. Fruit bodies appear in summer and autumn and may be locally abundant. It is a firm bolete with an olive-brown cap up to 20 cm (8 in) in diameter, with small orange or red pores on the underside (yellow when young). The stout ochre stem reaches 8–14 cm (3–6 in) high and 1–3 cm (0.4–1.2 in) wide, and is patterned with a red network. Like several other red-pored boletes, it stains blue when bruised or cut. While edible and

Galerina is a genus of small brown-spore saprobic mushroom-bearing fungi, with over 300 species found throughout the world. Galerina mushrooms are typically small and hygrophanous, with a slender and brittle stem. They are often found growing on wood, and when on the ground have a preference for mossy habitats. The genus is noted for some extremely poisonous species which are occasionally confused with hallucinogenic species of Psilocybe or with edible species. Prior to 1909, the genus was known as Galera, however, this was an invalid name due to the name being used earlier for a genus of

Limacella is a genus of mushroom-forming fungi in the family Amanitaceae in order Agaricales. Some of the species have been classified as members of genus Lepiota. Limacella was described by mycologist Franklin Sumner Earle in 1909. In some older classification schemes, Limacella has alternatively been placed in family Pluteaceae. The species formerly classified in the genus Limacella are now placed in 4 genera; Catatrama, Limacellopsis, Limacella, and Zhuliangomyces.

Synchytrium endobioticum is a chytrid fungus that causes the potato wart disease, or black scab. It also infects some other plants of the genus Solanum, though potato is the only cultivated host.

Amanita ocreata, commonly known as one of the many destroying angels, or more precisely the western North American destroying angel, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. The large fruiting bodies (the mushrooms) generally appear in spring; the cap may be white or ochre and often develops a brownish centre, while the stipe, ring, gill and volva are all white. A. ocreata resembles several edible species commonly consumed by humans, increasing the risk of accidental poisoning. Mature fruiting bodies can be confused with the edible A. velosa (springtime

Tricholoma fulvum is a mushroom of the agaric genus Tricholoma. One guide reports that the species is inedible, while another says the fruit bodies are edible. It is a pale brown to reddish-brown mushroom with crimped hat edges. Gills are yellowy-white and get brown spots. The spore powder is white. The stem brown externally, and hollow and yellow internally. It grows mycorrhizally with birch-trees.

Nosema apis is a microsporidian, a small, unicellular parasite recently reclassified as a fungus that mainly affects honey bees. It causes nosemosis, also called nosema, which is the most common and widespread of adult honey bee diseases. The dormant stage of N. apis is a long-lived spore which is resistant to temperature extremes and dehydration, and cannot be killed by freezing the contaminated comb. Nosemosis is a listed disease with the Office International des Epizooties (OIE).

Lentinula is a small genus of wood-inhabiting agarics. The neotropical species Lentinula boryana (= L. cubensis) is the type species. However, the best-known species is L. edodes, the shiitake. The genus was erected by Franklin Sumner Earle in 1909, and as of 2023 contains ten species, principally found in tropical regions.

Rhizopogon roseolus, shōro (Japanese: 松露/ショウロ), is a species of ectomycorrhizal fungus. It is considered a delicacy in Japan.

Chamaemyces is a genus of fungi in the family Agaricaceae. It was circumscribed by mycologist Franklin Sumner Earle in 1906.

Blastocladiomycota is part of a group of saprotrophic fungus that is one of the currently recognized phyla within the kingdom Fungi. Blastocladiomycota was originally the order Blastocladiales within the phylum Chytridiomycota until molecular and zoospore ultrastructural characters were used to demonstrate it was not monophyletic with Chytridiomycota. The order was first erected by Petersen for a single genus, Blastocladia, which was originally considered a member of the oomycetes. Accordingly, members of Blastocladiomycota are often referred to colloquially as "chytrids." However, some feel

Suillellus is a genus of bolete fungi in the family Boletaceae. It was originally described by William Alphonso Murrill in 1909 with Suillellus luridus (originally described as a species of Boletus) as the type species. The genus was later merged with Boletus, but was eventually resurrected in 2014, after molecular phylogenetics research demonstrated that Suillellus species comprised a different lineage than Boletus.

Peltigera praetextata, or the scaly dog pelt lichen, is a foliose lichen native to North America, Europe, and Asia. It is defined by small belly-button-like growths called phyllidia on its edges and centre.

Dibaeis is a genus of lichen-forming fungi in the family Icmadophilaceae. The genus is widely distributed in tropical regions. Dibaeis was circumscribed in 1909 by Frederic Edward Clements with Dibaeis rosea as the type species. Several species were transferred from other genera in a 1993 publication.

Boletellus ananas, commonly known as the pineapple bolete, is a mushroom in the family Boletaceae, and the type species of the genus Boletellus. Previously known as Boletus ananas and Boletus coccinea (among other synonyms), the species was given its current name by William Alphonso Murrill in 1909. The fruit body is characterized by the reddish-pink (or pinkish-tan to yellowish if an older specimen) scales on the cap that are often found hanging from the edge. The pore surface on the underside of the cap is made of irregular or angular pores up to 2 mm wide that bruise a blue color. It is

Pseudocolus fusiformis is a stinkhorn mushroom in the Phallaceae, a family well known for a remarkable range of fruit body types. It is commonly known as the stinky squid, because of its fetid odor, and its three or four upright "arms" which are connected at the top. The malodorous smell comes from the dark greenish slimy gleba covering the inside faces of the arms, and attracts insects that help to disperse the spores. It is the most widely distributed member of the genus Pseudocolus and has been found in the United States, Australia, and Asia.

Boletinellus merulioides, commonly known as the ash-tree bolete, is a species of bolete fungus in the family Boletinellaceae. Described as new to science in 1832, it is found in Asia and eastern North America, where it grows on the ground near ash trees due to a mutualistic relationship with a species of aphid.

Boletellus is a genus of fungi in the family Boletaceae. The genus has a widespread distribution, especially in subtropical regions, and contains about 50 species. The genus was first described by American mycologist William Alphonso Murrill in 1909. The genus name means "small Boletus".

The Blastocladiaceae are a family of fungi in the division Blastocladiomycota. It contains the following genera: Allomyces Blastocladiella Blastocladia Blastocladiopsis Microallomyces The family was circumscribed by Henning Eiler Petersen in 1909.

Pulveroboletus ravenelii, commonly known as Ravenel's bolete or the powdery sulfur bolete, is a species of bolete fungus in the family Boletaceae. It was described as new to science in 1853. The fruit bodies (mushrooms) have convex to flat, yellowish to brownish-red caps up to 10 cm (4 in) in diameter. On the cap underside, the pore surface is bright yellow before turning dingy yellow to grayish brown with age; it stains greenish blue then grayish brown after injury. A cottony and powdery partial veil remains as a ring on the stipe. The widely distributed species is known from Asia,

Pulveroboletus is a genus of fungi in the family Boletaceae. The genus has a cosmopolitan distribution and contains 41 species.

Mycetinis is a genus of fungus in the Omphalotaceae family, containing about eight species formerly classified in Marasmius.

Merismodes is a genus of fungi in the Cyphellopsidaceae family. It was previously included in the Niaceae family. The genus has a widespread distribution and contains 20 species.

Amanita calyptroderma also known as coccora, coccoli or the Pacific amanita, is a white-spored mushroom that fruits naturally in the Sierra Nevada and coastal forests of the western United States during the fall, winter and spring.

Boletinellus is a genus of fungi in the family Boletinellaceae (suborder Sclerodermatineae of the Boletales). The genus was first described by American mycologist William Alphonso Murrill in 1909.

Agonimia is a genus of lichen-forming fungi in the family Verrucariaceae. These lichens typically form crusts made of tiny grain-like clumps or small scale-like fragments on tree bark and rocks, with some species developing delicate leaf-like structures up to 5 mm across. The genus includes about 22 species found worldwide, characterized by their black flask-shaped reproductive structures and distinctive brick-patterned ascospores.

Tectella is a genus of fungi in the family Mycenaceae. The genus is widely distributed in northern temperate regions, and contains three species.

Placynthiella is a genus of lichen-forming fungi in the family Trapeliaceae. The genus has a complex naming history involving multiple independent descriptions by different scientists between 1909 and 1939, with the current accepted name dating to the earliest valid publication by Alexander Elenkin. These lichens form thin, dark green-brown crusts that blend closely with their growing surfaces, making them challenging to spot in the field on acidic soils, decaying wood, and bark. The genus is distinguished from similar lichen groups by its distinctive brown, brick-like fruiting body margins

Phaeosphaeria is a genus of fungi in the family Phaeosphaeriaceae. It has about 95 species. The genus was circumscribed by Japanese mycologist Ichiro Miyake in 1909, with Phaeosphaeria oryzae assigned as the type species.
