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

Contents

Taxonomy

It was described in 2002 by the Egon Horak, Anton Hausknecht and Dennis E. Desjardin who classified it as Conocybe volviornata. [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 volviornata is a small volvate mushroom.

Cap: 1-2.5cm wide and conical. The surface is pinkish-beige with a reddish-brown centre and a white fluffy to velvety coating from the pileicystidia. It is membranous, dry, thin and brittle and very strongly hygrophanous with the striations being visible from the margin to centre when moist. Stem: 4.5-9cm long and 1.5-2mm thick tapering upwards slightly from a 6mm wide base. The surface is the same colour or paler than the cap with a dense covering of caulocystidia. It is fragile but solid rather than hollow with a membranous, persistent white volva at the base. Gills: Adnexed, crowded, pale rust brown. Spore print: Rusty ochre. Spores: 12.5-15 x 9.5-12 x 7.5-9.5 μm. Sublimoniform to broadly amygdaliform in side view, sublimoniform to subhexagonal to submitriform in front view. Smooth with a thick wall of up to 1.2 μm with a distinctive germ pore. Rusty ochre-brown in colour. Basidia: 15-24 x 10-12 μm. 2 spored, broadly clavate. [3]

Habitat and distribution

The specimens studied by Horak, Hausknecht and Desjardin were found growing on soil in Indonesian rainforests dominated by Fagaceae trees. [3]

<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.

<span class="mw-page-title-main">Bolbitiaceae</span> Family of fungi

The Bolbitiaceae are a family of mushroom-forming basidiomycete fungi. A 2008 estimate placed 17 genera and 287 species in the family. Bolbitiaceae was circumscribed by mycologist Rolf Singer in 1948.

<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.

<i>Conocybe rickenii</i> Species of fungus

Conocybe rickenii is a mushroom from the genus Conocybe. Its edibility is disputed, and it has the appearance of a typical little brown mushroom with a small, conical cap, and long, thin stem. In colour, it is generally a cream-brown, lighter on the stem, and it has a thin layer of flesh with no distinct smell or taste. It is a coprophilous fungus, feeding off dung and it is most common on very rich soil or growing directly from dung. It can be found in Europe, Australia and Pacific islands.

<i>Amanita nothofagi</i> Species of fungus

Amanita nothofagi is a species of fungus in the family Amanitaceae. Endemic to New Zealand, the species was first described by mycologist Greta Stevenson in 1962. The fruit bodies have dark brown caps that are up to 13 cm (5.1 in) in diameter and covered with patches of soft greyish-brown scales or warts. The gills underneath the cap are crowded together, free from attachment to the stem, and white, becoming tinged with yellow in age. The stem of the mushroom is 4–14 cm (1.6–5.5 in) long by 0.5–2.5 cm (0.2–1.0 in) thick, and has a ring. The spore print is white, and individual spores are spherical to ellipsoid, measuring 7.5–9 by 7.5–9 micrometres. The mushroom may be confused with another New Zealand species, A. australis, but can be distinguished by certain characteristics. Amanita nothofagi is a mycorrhizal species, and grows in association with native New Zealand trees such as Southern Beech.
