Clitopaxillus alexandri is a species of fungus in the family Pseudoclitocybaceae . It has been given the recommended English name of Alexander's funnel. [1] Basidiocarps (fruit bodies) are agaricoid and resemble those of Clitocybe species. The species is saprotrophic and is mainly known from Europe. [2]

Description

The pileus (cap) is convex at first becoming umbonate with age, smooth, 50–200 mm in diameter, grey to reddish brown, cracking with age. The lamellae (gills) are decurrent and paler than the pileus. The stipe (stem) is up to 100 mm tall, and yellowish white. The context is whitish with an almond smell. The spore print is white. Microscopically the basidiospores are smooth, ellipsoid, weakly amyloid, and measure 4.5–5.5 x 3.5–4.0 μm. [2]

Similar species

The recently described Clitopaxillus fibulatus is very similar, but differs microscopically in its slightly larger basidiospores and hyphae with more abundant clamp connections. It also differs in having a subarctic and alpine distribution. [2]

Habitat and distribution

The species typically occurs in leaf litter with pine, oak, and cedar. It was originally described from France and is mostly known from southern, western, and central Europe, extending into North Africa. [2]

Conservation

Clitopaxillus alexandri is assessed as "critically endangered" on the Red Data List of Threatened British Fungi, [3] "vulnerable" on the Dutch red list, [4] and "threatened" or "near threatened" on some other European red lists, including those of Germany, [5] Hungary, [6] and Norway. [7]

<i>Inocybe</i> Genus of fungi

Inocybe is a large genus of mushroom-forming fungi with over 1400 species, including all forms and variations. Members of Inocybe are mycorrhizal, and some evidence shows that the high degree of speciation in the genus is due to adaptation to different trees and perhaps even local environments.

<i>Hygrocybe</i> Genus of fungi

Hygrocybe is a genus of agarics in the family Hygrophoraceae. Called waxcaps in English, basidiocarps are often brightly coloured and have dry to waxy caps, white spores, and smooth, ringless stems. In Europe they are characteristic of old, unimproved grasslands which are a declining habitat, making many Hygrocybe species of conservation concern. Four of these waxcap-grassland species, Hygrocybe citrinovirens, H. punicea, H. spadicea, and H. splendidissima, are assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. Elsewhere waxcaps are more typically found in woodlands. Most are ground-dwelling and all are believed to be biotrophs. Around 150 species are recognized worldwide. Fruit bodies of several Hygrocybe species are considered edible and are sometimes offered for sale in local markets.

<i>Melanoleuca</i> Genus of fungi

Melanoleuca is a poorly known genus of saprotrophic mushrooms traditionally classified in the family Tricholomataceae. Most are small to medium sized, white, brown, ocher or gray with a cylindrical to subcylindrical stipe and white to pale yellowish gills. The basidiospores are ellipsoid and ornamented with amyloid warts. Melanoleuca is considered a difficult group to study due to their macroscopic similarities among species and the need of a thorough microscopic analysis to separate species. DNA studies have determined that this genus is closely related to Amanita and Pluteus and that it does not belong to the family Tricholomataceae.

<i>Crepidotus versutus</i> Species of fungus

Crepidotus versutus, commonly known as the evasive agaric, is a species of fungus in the family Crepidotaceae. It is saprobic on wood, like other Crepidotus species, but it can also decompose herbaceous forest litter. The species is characterized by large, punctate, ellipsoid spores, and the white, hairy pileus.

<i>Crucibulum</i> Genus of fungi

Crucibulum is a genus in the Nidulariaceae, a family of fungi whose fruiting bodies resemble tiny egg-filled bird's nests. Often called "splash cups", the fruiting bodies are adapted for spore dispersal by using the kinetic energy of falling drops of rain. The "eggs" inside the bird's nests are hard waxy shells containing spores, and tend to stick to whatever nearby herbage they land on, thus increasing the odds of being consumed and dispersed by herbivorous animals. Members of this genus are saprobic, obtaining nutrients from dead organic matter, and are typically found growing on decayed wood and wood debris. The three known Crucibulum species are distinguished from other genera of the Nidulariaceae by their relatively simple funiculus – a cord of hyphae that connects the peridiole to the exterior of the bird's nest.

<i>Atheniella flavoalba</i> Species of fungus

Atheniella flavoalba, which has the recommended name of ivory bonnet in the UK, is a species of agaric in the family Cyphellaceae. The cap is initially conical, before becoming convex and then flat; it may reach up to 1.5 cm (0.6 in) across. The cap is ivory-white to yellowish white, sometimes more yellowish at the center. The tubular stems are up to 8 cm (3.1 in) long and 2.5 mm (0.10 in) thick, and have long, coarse white hairs at their bases. Atheniella flavoalba is found in Europe, the Middle East, and North America, where it grows scattered in pastures or in dense groups under conifers and on humus in oak woods.

<i>Amanita pekeoides</i> Species of fungus from New Zealand

Amanita pekeoides is a species of fungus in the family Amanitaceae. It is endemic to New Zealand.

<i>Catathelasma imperiale</i> Species of fungus

Catathelasma imperiale, also known as Catathelasma imperialis, and commonly known as the imperial mushroom, Hutsul mushroom, or korban, is a species of agaric in the family Biannulariaceae. Basidiocarps are stocky, with a double annulus (ring), and a tapering to rooting stipe (stem). The species is ectomycorrhizal with conifers and is found in continental Europe and Asia. Reports from North America are unconfirmed and may refer to Catathelasma evanescens or similar species. Fruit bodies are edible and collected for food in China and elsewhere. The species is widespread but uncommon and is assessed as globally "near threatened" on the IUCN Red List of Threatened Species.

<i>Marasmius funalis</i> Species of fungus

Marasmius funalis is a species of Marasmiaceae fungus known only from Japan. The species produces small mushrooms with reddish-brown caps up to 6 millimetres (0.24 in) in diameter and dark-brown, threadlike stems of up to 50 millimetres (2.0 in) in length. The species has a number of distinctive microscopic features, including very long cystidia on the stem, visible as bristles. Described in 2002 by Haruki Takahashi, the species grows on dead wood. The closest relative of M. funalis is M. liquidambari, known from Mexico and Papua New Guinea, and it is also similar in appearance to M. hudonii and Setulipes funaliformis, the latter of which was named after M. funalis.

<i>Porpolomopsis calyptriformis</i> Species of fungus

Porpolomopsis calyptriformis, commonly known as the pink wax cap, ballerina waxcap or salmon waxy cap, is a species of agaric in the family Hygrophoraceae. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in the species being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. A similar but as yet unnamed species occurs in North America.

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

Volvopluteus asiaticus is a species of mushroom in the Pluteaceae family. The cap of this mushroom is about 70–90 mm (2.8–3.5 in) in diameter, greyish brown to brown. The gills start out 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. asiaticus is a saprotrophic fungus that was originally described as growing on the ground, in the humus layer. It is only known from Hokkaido (Japan).

It was originally described from England and is part of a species complex as yet unresolved.

<i>Pseudotricholoma</i> Genus of fungi

Pseudotricholoma is a genus of fungi in the family Tricholomataceae. The genus contains three species known from North America. Europe, and the Azores. Basidiocarps resemble those of the genus Tricholoma, with a dry fibrillose pileus and white to brown lamellae that have adnate to emarginate attachment and stain reddish when damaged, eventually turning black. Microscopically, the basidiospores are smooth, ellipsoid to ellipsoid-oblong, thin-walled and amyloid. Cheilocystidia are rare to absent and pleurocystidia are absent. The pileipellis is a cutis and clamp connections are present. Species in Pseudotricholoma are found on soil in grasslands and woods. They are probably biotrophic, and may be ectomycorrhizal.
