Inosperma erubescens (formerly Inocybe erubescens, also formerly named I. patouillardii), and also commonly known as the deadly fibrecap, brick-red tear mushroom or red-staining Inocybe, is a poisonous basidiomycete fungus, one of many in the original genus Inocybe and one of the few known to have caused death. It is found growing in small groups on leaf litter in association with beech. All mushroom guidebooks as well as mushroom hunters advise that the entire Inocybaceae should be avoided for consumption. The fruit bodies (i.e., the mushrooms) appear in spring and summer; the bell-shaped

Inocybe rimosa (formerly known as Inocybe fastigiata), commonly known as straw-colored fiber head, is a poisonous mushroom native to Europe. Its toxic ingredient is muscarine, discovered during the 1930s. Serious poisoning can result from consuming any quantity of the mushroom. German naturalist Jacob Christian Schäffer described this species in 1774. Lucien Quélet transferred it to the genus Inocybe in 1872. The tan (or rarely whitish) cap is cone-shaped then expands, generally retaining an umbo and a darker center. Its surface is fibrous. The gills are light grayish and brown with age. The

Inosperma maculatum, formerly known as Inocybe maculata and commonly known as the frosty fibrecap or brown inocybe, is a species of mushroom in the family Inocybaceae. It was first described by Jean Louis Émile Boudier in 1885. It is a medium-sized brown mushroom with a fibrous, brown cap with white remnants of a universal veil in the middle. The stem is cream or brown. The species is ectomycorrhizal and grows at the base of various trees, including beech. Inosperma maculatum is found throughout Eurasia and North America. It is poisonous, containing muscarine. Possible symptoms include

Inosperma cookei, commonly known as the straw fibrecap, is a species of mushroom in the family Inocybaceae. It was first described in 1892 by Giacomo Bresadola, and is named in honour of Mordecai Cubitt Cooke. The species is found in Europe, Asia, and North America. It produces small mushrooms of an ochre colour, with a prominent umbo, fibres on the cap and a distinctive bulb at the base of the stem. It grows from soil in mixed woodland, and is encountered in summer and autumn, though is not common. Ecologically, it feeds through use of ectomycorrhiza. Inosperma cookei has been described as

Inosperma calamistratum, until 2019 known as Inocybe calamistrata, is a species of Inocybaceae fungus. The tannish cap is up to 5 centimetres (2 in) wide. The stem is up to 15 cm (6 in) long, possibly staining reddish above and/or blue-green below. The beige gills are fairly close and produce a brown spore print. The scent is typically pungent. Perhaps similar are Inocybe calospora, which does not stain, and I. tahquamenonensis, which is purplish. The species is found in Europe and North America (July–September to the east; August–November by the West Coast). Orson K. Miller Jr. and Hope

Inosperma bongardii is an agaric fungus in the family Inocybaceae. It was originally described as a species of Agaricus by German botanist Johann Anton Weinmann in 1836. Lucien Quélet transferred it to the genus Inocybe in 1872. A 2019 multigene phylogenetic study by Matheny and colleagues found that I. bongardii and its relatives in the subgenus Inosperma were only distantly related to the other members of the genus Inocybe. Inosperma was raised to genus rank and the species became Inosperma bongardii. It is a common species with a widespread distribution. Fruit bodies grow on the ground,

Inosperma adaequatum, known as Inocybe adaequata until 2019, is a species of fungus in the family Inocybaceae found in North America and Europe.

Xeromphalina setulipes is a species of fungus of the family Mycenaceae. First collected in 2005, it was described and named in 2010 by Fernando Esteve-Raventós and Gabriel Moreno, and is known only from oak forests in Ciudad Real Province, Spain. The species produces mushrooms with dark reddish-brown caps up to 15 millimetres (0.59 in) across, dark purplish-brown stems up to 45 millimetres (1.8 in) in height and distinctive, arched, brown gills. The mushrooms were found growing directly from the acidic soil of the forest floor, surrounded by plant waste, during November. Morphologically, the

Inocybe calamistratoides is a species of Inocybaceae fungus found in New Zealand.

Inosperma is a genus of gilled mushroom in the family Inocybaceae. Previously defined as a subgenus within the large genus Inocybe by Robert Kühner in 1980, these fungi were found to be more distantly related in a 2019 multigene phylogenetic study by Matheny and colleagues.

Pseudosperma is a genus of mushrooms in the family Inocybaceae. It is widely distributed, being found in both temperate and tropical regions. Pseudosperma was once considered to be part of the genus Inocybe. However, in 2020, Matheny et. al. split the genus into several other genera, including Pseudosperma.
