Type species
Endoptychum agaricoides
Czern. (1845)

Endoptychum is a genus of secotioid fungi in the family Agaricaceae. Like the majority of secotioid taxa, the individual species of Endoptychum are thought to be recent mutations from agaricoid species, hence, Endoptychum is likely not a valid monophyletic genus.

So far, molecular phylogeny and morphological study has revealed that E. depressum clearly is a species of Agaricus and E. agaricoides , the type species, is a species of Chlorophyllum . E. depressum has been renamed Agaricus inapertus Vellinga. Recognition of the name Chlorophyllum agaricoides (Czern.) Vellinga would entail deprecation of the entire genus name Endoptychum in favor of Chlorophyllum and awaits a formal decision of the International Botanical Congress. [1] [2] [3] [4]

E. agaricoides is inedible. [5]

<span class="mw-page-title-main">Secotioid</span> Type of fungi

Secotioid fungi are an intermediate growth form between mushroom-like hymenomycetes and closed bag-shaped gasteromycetes, where an evolutionary process of gasteromycetation has started but not run to completion. Secotioid fungi may or may not have opening caps, but in any case they often lack the vertical geotropic orientation of the hymenophore needed to allow the spores to be dispersed by wind, and the basidiospores are not forcibly discharged or otherwise prevented from being dispersed —note—some mycologists do not consider a species to be secotioid unless it has lost ballistospory.

<i>Lepiota</i> Genus of fungi

Lepiota is a genus of gilled mushrooms in the family Agaricaceae. All Lepiota species are ground-dwelling saprotrophs with a preference for rich, calcareous soils. Basidiocarps are agaricoid with whitish spores, typically with scaly caps and a ring on the stipe. Around 400 species of Lepiota are currently recognized worldwide. Many species are poisonous, some lethally so.

<i>Tricholoma argyraceum</i> Species of fungus

Tricholoma argyraceum is a grey-capped mushroom of the large genus Tricholoma. It has been often confused with the similar-looking Tricholoma scalpturatum.

<i>Chlorophyllum</i> Genus of fungi

Chlorophyllum is a genus of large agarics similar in appearance to the true parasol mushroom. Chlorophyllum was originally coined in 1898, a time when spore color was the deciding factor for differentiating genera. It was termed in order to describe the poisonous green-spored C. molybdites which shared many characteristics of the mushrooms within the genus Lepiota but lacked the all important white spores. The name derives from Greek Chloro meaning green and phyllo meaning leaf. It remained as a monotypic genus until recently when modern DNA analyses concluded that many of the mushrooms contained in the genus Macrolepiota actually had more in common genetically with the Chlorophyllum molybdites than with the other members of the Macrolepiota. The genus has a widespread distribution, with many species found in tropical regions. The best known members are the edible shaggy parasol, a name applied to three very similar species Chlorophyllum rhacodes, C. olivieri and C. brunneum, and the poisonous C. molybdites, which is widespread in subtropical regions around the world.

<i>Macrolepiota</i> Genus of fungi

Macrolepiota is a genus of white spored, gilled mushrooms of the family Agaricaceae. The best-known member is the parasol mushroom (M. procera). The widespread genus contains about 40 species.

<i>Macrolepiota clelandii</i> Species of mushroom-forming fungus

Macrolepiota clelandii, commonly known as the slender parasol or graceful parasol, is a species of mushroom-forming fungus in the family Agaricaceae. The species is found in Australia and New Zealand, where it fruits singly or in small groups on the ground in eucalypt woodlands, parks, and roadsides. It is a tall mushroom up to roughly 20 cm (8 in), with a broad cap covered with distinctive rings of dark brown scales. The whitish gills on the cap underside are closely spaced and free from attachment to the slender stipe, which has a loose ring on its upper half, and a bulbous base. The edibility of the mushroom is not known with certainty, but closely related parasol mushrooms are edible and some are very sought after.

<i>Leucoagaricus</i> Genus of fungi

Leucoagaricus is a genus of mushroom-forming fungi in the family Agaricaceae. As of March 2023 there are over 200 accepted species of Leucoagaricus with ongoing research into the genus adding several more each year. Leucocoprinus is a similar genus and considered by some sources to be indistinct from Leucoagaricus based on genetic data that demonstrates they are monophyletic. Species are separated into these genera based on macroscopic features such as cap striations in Leucocoprinus or the more persistent basidiocarps (mushrooms) of Leucoagaricus as well as microscopic features such as the lack of a germ pore in Leucoagaricus species. As a result of the similarities and disagreement on taxonomy, many of the species within these genera have formerly been classified in the other and may still be known by previous classifications. For instance the species Leucoagaricus gongylophorus is cultivated by fungus-growing ants but was formerly known as Leucocoprinus gongylophorus whilst other species cultivated by the lesser attine ants are still classified as undescribed Leucocoprinus species.

Secotium is a genus of fungi in the family Agaricaceae. The members of this genus are closely related to ordinary Agaricus mushrooms, but do not open out in the usual way; this has given rise to the term "secotioid" for such mushrooms in general. They are thought to form an evolutionary link between agarics and gasteroid fungi. Secotium is a widespread genus, with species that are predominantly found in warm and arid regions.

<i>Leucopholiota decorosa</i> Species of fungus

Leucopholiota decorosa is a species of fungus in the mushroom family Tricholomataceae. Commonly known as the decorated pholiota, it is distinguished by its fruit body which is covered with pointed brown, curved scales on the cap and stem, and by its white gills. Found in the eastern United States, France, and Pakistan, it is saprobic, growing on the decaying wood of hardwood trees. L. decorosa was first described by American mycologist Charles Horton Peck as Agaricus decorosus in 1873, and the species has been transferred to several genera in its history, including Tricholoma, Tricholomopsis, Armillaria, and Floccularia. Three American mycologists considered the species unique enough to warrant its own genus, and transferred it into the new genus Leucopholiota in a 1996 publication. Lookalike species with similar colors and scaly fruit bodies include Pholiota squarrosoides, Phaeomarasmius erinaceellus, and Leucopholiota lignicola. L. decorosa is considered an edible mushroom.

<i>Agaricus deserticola</i> Species of fungus in the family Agaricaceae endemic to southwestern and western North America

Agaricus deserticola, commonly known as the gasteroid agaricus, is a species of fungus in the family Agaricaceae. Found only in southwestern and western North America, A. deserticola is adapted for growth in dry or semi-arid habitats. The fruit bodies are secotioid, meaning the spores are not forcibly discharged, and the cap does not fully expand. Unlike other Agaricus species, A. deserticola does not develop true gills, but rather a convoluted and networked system of spore-producing tissue called a gleba. When the partial veil breaks or pulls away from the stem or the cap splits radially, the blackish-brown gleba is exposed, which allows the spores to be dispersed.

<i>Agaricus silvaticus</i> Species of fungus

Agaricus silvaticus, otherwise known as the scaly wood mushroom, blushing wood mushroom, or pinewood mushroom, is a species of mushroom often found in groups in coniferous forests from early summer, or September through to November in Europe, North Africa and North America.

<i>Deconica coprophila</i> Species of fungus

Deconica coprophila, commonly known as the dung-loving psilocybe, meadow muffin mushroom, or dung demon, is a species of mushroom in the family Strophariaceae. First described as Agaricus coprophilus by Jean Baptiste François Pierre Bulliard in 1793, it was transferred to the genus Psilocybe by Paul Kummer in 1871. In the first decade of the 2000s, several molecular studies showed that the Psilocybe was polyphyletic, and the non-bluing (non-hallucinogenic) species were transferred to Deconica.

<i>Montagnea arenaria</i> Species of fungus

Montagnea arenaria, commonly known as the gasteroid coprinus, is a species of secotioid fungus in the family Agaricaceae. Originally named Agaricus arenarius by Augustin Pyramus de Candolle in 1815, it was transferred to the genus Montagnea by Sanford Myron Zeller in 1943. The species is characterized by a cap that has an apical disc, radial gills, a hymenophore, and spores with a prominent germ pore. It is inedible.

<i>Coniolepiota</i> Genus of fungi

Coniolepiota is a fungal genus in the family Agaricaceae. The genus is monotypic, containing only a single species, Coniolepiota spongodes. It was first described from Thailand, and later also reported from Bangladesh and China. The species has also been observed in Malaysia, Singapore, Cambodia, Indonesia, Taiwan, Philippines, and South Africa.

<i>Agaricus inapertus</i> Species of fungus

Agaricus inapertus, commonly known as the mountain gasteroid agaricus, is a species of secotioid fungus in the genus Agaricus. It was first described by American mycologists Rolf Singer and Alexander H. Smith in 1958 as Endoptychum depressum. Molecular analysis later proved it to be aligned with Agaricus, and it was formally transferred in a 2003 publication.

Eriocybe is a fungal genus in the family Agaricaceae. Circumscribed by mycologist Else Vellinga in 2011, it is a monotypic genus, containing the single species Eriocybe chionea, found in northern Thailand. The genus name is derived from the Ancient Greek words ἔριον, meaning "wool" and κύβη, "head". The specific epithet comes from the Latin translation of the Greek χιόνεος, meaning "snow white".

<i>Chlorophyllum agaricoides</i> Species of fungus

Chlorophyllum agaricoides, commonly known as the gasteroid lepiota, puffball parasol, false puffball, or puffball agaric, is a species of fungus belonging to the family Agaricaceae. When young, it is edible, and has been traditionally eaten in Turkey for many years.
