Catathelasma evanescens is a species of fungus in the family Biannulariaceae, and the type species of the genus Catathelasma . The species was described by Ruth Ellen Harrison Lovejoy in 1910. [1]

Description and Distribution

The genus includes the commoner C. imperiale and C. ventricosum, but the type species, C. evanescens, seems extremely rare. In 1914 it was only known from the location of the initial find, which is at an altitude of 3500 m. in the Medicine Bow Mountains of Wyoming. [2] It is distinguished from the other species because the gills are fairly distant ("subdistant") and because it has a large persistent volva around the base of the stipe. [3]

The species name may refer to the evanescent ring.

The following summary is taken from Mrs. Lovejoy's original description. [1]

Phallaceae is a family of fungi, commonly known as stinkhorns, within the order Phallales. Stinkhorns have a worldwide distribution, but are especially prevalent in tropical regions. They are known for their foul-smelling, sticky spore masses, or gleba, borne on the end of a stalk called the receptaculum. The characteristic fruiting-body structure, a single, unbranched receptaculum with an externally attached gleba on the upper part, distinguishes the Phallaceae from other families in the Phallales. The spore mass typically smells of carrion or dung, and attracts flies, beetles and other insects to help disperse the spores. Although there is great diversity in body structure shape among the various genera, all species in the Phallaceae begin their development as oval or round structures known as "eggs". The appearance of Phallaceae is often sudden, as gleba can erupt from the underground egg and burst open within an hour. According to a 2008 estimate, the family contains 21 genera and 77 species.

<span class="mw-page-title-main">Partial veil</span> Mushroom anatomy

In mycology, a partial veil is a temporary structure of tissue found on the fruiting bodies of some basidiomycete fungi, typically agarics. Its role is to isolate and protect the developing spore-producing surface, represented by gills or tubes, found on the lower surface of the cap. A partial veil, in contrast to a universal veil, extends from the stem surface to the cap edge. The partial veil later disintegrates, once the fruiting body has matured and the spores are ready for dispersal. It might then give rise to a stem ring, or fragments attached to the stem or cap edge. In some mushrooms, both a partial veil and a universal veil may be present.

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

Amanita arocheae, also known as the Latin American death cap, is a mushroom of the large genus Amanita, which occurs in Colombia, Central America and South America. Deadly poisonous, it is a member of section Phalloideae and related to the death cap, A. phalloides.

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

The European white egg, bearded amanita or European egg amidella, is a species of fungus of the genus Amanita in the family Amanitaceae. It is a large, white-colored fungus, often tinged with cream. Native to Europe, it is found on plains as well as mountains in the Mediterranean region. It is similar to some deadly poisonous species.

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

Amanita abrupta, commonly known as the American abrupt-bulbed amanita or the American abrupt-bulbed lepidella, is a possibly toxic species of fungus in the family Amanitaceae. Named for the characteristic shape of its fruit bodies, this white Amanita has a slender stem, a cap covered with conical white warts, and an "abruptly enlarged" swollen base. This terrestrial species grows in mixed woods in eastern North America and eastern Asia, where it is thought to exist in a mycorrhizal relationship with a variety of both coniferous and deciduous tree species.

<i>Catathelasma</i> Genus of fungi


Catathelasma is a genus of fungi in the family Biannulariaceae. Basidiocarps are agaricoid, with a conspicuous veil, adnate to decurrent lamellae, and amyloid basidiospores. The genus is separated on DNA characteristics as well as morphology. Species are known from North America, Europe, and Asia and are ectomycorrhizal, forming an association with the living roots of trees.

<i>Amanita bisporigera</i> Poisonous species of fungus in the family Amanitaceae endemic to North America

Amanita bisporigera is a deadly poisonous species of fungus in the family Amanitaceae. It is commonly known as the eastern destroying angel amanita, the eastern North American destroying angel or just as the destroying angel, although the fungus shares this latter name with three other lethal white Amanita species, A. ocreata, A. verna and A. virosa. The mushroom has a smooth white cap that can reach up to 10 centimetres across and a stipe up to 14 cm tall with a white skirt-like ring near the top. The bulbous stipe base is covered with a membranous sac-like volva. The white gills are free from attachment to the stalk and crowded closely together. As the species name suggests, A. bisporigera typically bears two spores on the basidia, although this characteristic is not immutable. A. bisporigera closely resembles a few other white amanitas, including the equally deadly A. virosa and A. verna.

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

Amanita exitialis, also known as the Guangzhou destroying angel, is a mushroom of the large genus Amanita. It is distributed in eastern Asia, and probably also in India where it has been misidentified as A. verna. Deadly poisonous, it is a member of section Phalloideae and related to the death cap A. phalloides. The fruit bodies (mushrooms) are white, small to medium-sized with caps up to 7 cm (2.8 in) in diameter, a somewhat friable ring and a firm volva. Unlike most agaric mushrooms which typically have four-spored basidia, the basidia of A. exitialis are almost entirely two-spored. Eight people were fatally poisoned in China after consuming the mushroom in 2000, and another 20 have been fatally poisoned since that incident. Molecular analysis shows that the species has a close phylogenetic relationship with three other toxic white Amanitas: A. subjunquillea var. alba, A. virosa and A. bisporigera.

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

Amanita australis is a species of fungus in the family Amanitaceae. It produces small- to medium-sized fruit bodies, with brown caps up to 9 centimetres in diameter covered with pyramidal warts. The gills on the underside of the cap are white, closely crowded together, and free from attachment to the stem. The stem, up to 9 cm long, has a ring and a bulbous base. The mushroom may be confused with another endemic New Zealand species, A. nothofagi, but can be distinguished by differences in microscopic characteristics.

<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.

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

Amanita atkinsoniana, also known as the Atkinson's amanita, is a species of fungus in the family Amanitaceae. The fruit body is white to brownish, with caps up to 12.5 centimetres in diameter, and stems up to 20 cm long. The surface of the cap is covered with brownish conical warts.

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

Amanita rubrovolvata, commonly known as the red volva amanita, is a species of fungus in the family Amanitaceae. The fungus produces small to medium-sized mushrooms, with reddish-orange caps up to 6.5 millimetres wide. The stems are up to 10 cm (4 in) tall, cream-coloured above the ring and cream to yellowish below it. The stem ends in a roughly spherical bulb at the base, which is covered with bright orange patches.

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

Amanita ceciliae, commonly called snakeskin grisette, strangulated amanita, and the Cecilia's ringless amanita, is a basidiomycete fungus in the genus Amanita. First described in 1854 by Miles Joseph Berkeley and Christopher Edmund Broome, it was given its current name by Cornelis Bas in 1984. It is characterized by bearing a large fruit body with a brown cap 5–12 cm (2.0–4.7 in) across. The cap has charcoal-grey patches, which are easily removable. The stipe is 7–18 cm (2.8–7.1 in) long, white in colour, and there is no ring on it. It is slightly tapered to the top, and has irregular cottony bands girdling the base. The universal veil is grey. Spores are white, spherical in shape, non-amyloid, and measure 10.2–11.7 micrometres. The mushrooms are considered edible, but field guides typically advise caution in selecting them for consumption, due to risks of confusion with similar toxic species. A. ceciliae is found in woods throughout Europe and North America, where it fruits during summer and autumn.

<i>Volvopluteus michiganensis</i> Species of fungus

Volvopluteus michiganensis is a species of mushroom in the family Pluteaceae. It was originally described under the name Pluteus michiganensis but molecular studies have placed it in the Volvopluteus, a genus described in 2011. The cap of this mushroom is about 7–9 cm (2.8–3.5 in) in diameter, gray, and has a cracked margin that is sticky when fresh. The gills start out as white but they soon turn pink. The stipe is white and has a volva at the base. Microscopical features and DNA sequence data are of great importance for separating this taxon from related species. V. michiganensis is a saprotrophic fungus that was originally described as growing on sawdust. It has only been reported from Michigan (US) and the Dominican Republic.
