Conocybe volvata is a species of mushroom-producing fungus in the family Bolbitiaceae. [1] [2]

Contents

Taxonomy

It was described in 2001 by the K. Agregtitous Thomas, Anton Hausknecht and P. Manimohan who classified it as Conocybe volvata. [3]

It is notable as being one of the few Conocybe species which has a volva and subsequently was placed in Conocybe sect. Singerella along with the other volvate species. [3]

Description

Conocybe volvata is a small brown volvate mushroom.

Cap: 1.5-5.5cm wide and campanulate, conical or conico-convex sometimes with an obtuse umbo. The surface is brown and may be concolorous all over or present with reddish brown colouration towards the centre disc and light brown colours towards the margin. It is hygrophanous and becomes greyish orange as the moisture content changes. The surface is smooth with fine striations visible when moist and the flesh is brownish white and up to 1.5mm thick at the centre. Gills: Adnexed to adnate, light brown to brown and close to crowded. Up to 3.5mm wide with lamellulae (partial gills) of different lengths. Stem: 5-14cm long and 1.5-6mm thick becoming narrower at the apex. The surface has fine striations along its length and is white towards the apex with a pruinose coating visible with a lens and reddish brown towards the base. The volva is split in half when open and has a cottony texture. Spores: 9.5-14.5 x 7-9 x 6-8 μm. Ellipsoid to oviform-ellipsoid and frequently subhexagonal in face view. Smooth, thick walled and with an apically truncated broad germ pore. Pale brown to brown in KOH. Basidia: 19-26.5 x 11.5-15.5 μm. Clavate, 4 spored. [3]

Habitat and distribution

The specimens studied by Thomas, Hausknecht and Manimohan were found in Kerala State, India where they were growing on elephant dung. [3]

Panaeolus tropicalis is a species of psilocybin producing mushroom in the family Bolbitiaceae. It is also known as Copelandia tropicalis.

<i>Conocybe rugosa</i> Species of mushroom

Conocybe rugosa is a common species of mushroom that is widely distributed and especially common in the Pacific Northwest of the United States. It grows in woodchips, flowerbeds and compost. It has been found in Europe, Asia and North America. It contains the same mycotoxins as the death cap mushroom. Conocybe rugosa was originally described in the genus Pholiotina, and its morphology and a 2013 molecular phylogenetics study supported its continued classification there.

<i>Pholiotina cyanopus</i> Species of fungus

Pholiotina cyanopus is a species of fungus that contains psychoactive compounds including psilocybin and the uncommon aeruginascin. Originally described as Galerula cyanopus by American mycologist George Francis Atkinson in 1918. It was transferred to Conocybe by Robert Kühner in 1935 before being transferred to Pholiotina by Rolf Singer in 1950. A 2013 molecular phylogenetics study found it to belong to a group of species currently assigned to Pholiotina that are more closely related to Galerella nigeriensis than to Pholiotina or Conocybe. It is likely that it will be moved to a different genus in the future, but this has not happened yet.

<span class="mw-page-title-main">Volva (mycology)</span> Cup-like structure at the base of a mushroom

In mycology, a volva is a cup-like structure at the base of a mushroom that is a remnant of the universal veil, or the remains of the peridium that encloses the immature fruit bodies of gasteroid fungi. This macrofeature is important in wild mushroom identification because it is an easily observed, taxonomically significant feature that frequently signifies a member of Amanitaceae. This has particular importance due to the disproportionately high number of deadly poisonous species contained within that family.

<i>Pholiotina</i> Genus of fungi

Pholiotina is a genus of small agaric fungi. It was circumscribed by Swiss mycologist Victor Fayod in 1889 for Conocybe-like species with partial veils. The genus has since been expanded to include species lacking partial veils.
