Cystolepiota amazonica is a species of mushroom-producing fungus in the family Agaricaceae. [1] [2]

Taxonomy

It was described in 1989 by the German mycologist Rolf Singer who classified it as Cystolepiota amazonica. [3]

Description

Cystolepiota amazonica is a very small brownish mushroom with white flesh.

Cap: 3mm wide and high and campanulate (bell shaped). The surface is redddish-brown to light chesnut colour. It is not hygrophanous or viscid ad is wrinkled (rugulose) or smooth with subsulcate striations at the margins. Gills: Free or narrowly adnexed, subconfluent. White but drying to pale or dirty brown. Stem: 1.2 cm tall and 0.8mm thick tapering slightly with a thinner apex. The surface is chestnut colour and smooth with white mycelium at the base. No stem ring was observed by Singer. Spores: Globose or subglobose. Dextrinoid, cyanophilic, hyaline, not metachromatic. 2.5-2.8 x 2-2.2μm. Basidia: 11–12.5 x 3.5-4.5 μm. Four spored. Smell: Indistinct. [3]

Habitat and distribution

The specimens studied by Singer were found growing solitary on fallen, rotting leaves of Dicotyledon plants in the tropical forests of Brazil, 30 km North of Manaus. [3]

<i>Leucocoprinus cepistipes</i> Species of fungus

Leucocoprinus cepistipes, is a species of fungus in the family Agaricaceae. It is typically found on wood debris, such as wood chips but may also grow in potted plants or greenhouses. Typical characteristics include a fine-scaled bell-shaped cap, a partial veil, and a tendency to bruise a yellow to brown when handled.

<i>Mycena nargan</i> Species of fungus in the family Mycenaceae

Mycena nargan, commonly known as the Nargan's bonnet, is a species of fungus in the family Mycenaceae, and the sole member of the section Nargan in the genus Mycena. Reported as a new species in 1995, it is known predominantly from Southern Australia. The saprobic fungus produces mushrooms that grow on well-decayed wood, often on the underside of wood lying in litter. The dark chestnut-coloured caps are covered with white, easily removed scales, and reach diameters of up to 2 cm (0.8 in) wide. The pale, slender stems are up to 5 cm (2.0 in) long and have white scales at the base. On the underside of the cap, the cream-coloured gills are widely spaced and bluntly attached to the stem. The edibility of the mushroom is unknown.

<i>Inocybe godeyi</i> Species of fungus

Inocybe godeyi is a species of Inocybaceae fungus found in Europe. The species produces mushrooms with cone-shaped caps up to 5 cm (2 in) in diameter. The caps are cream, becoming browner, but they bruise red. The stem is up to 6 cm (2 in) long, and has a "bulb" at the base. The white flesh has a strong smell and an acrid taste. The mushrooms can be found on forest floors in autumn months; the species forms an ectomycorrhizal relationship to surrounding trees, favouring beech. I. godeyi is known to be poisonous, containing muscarine compounds, and consumption of the mushrooms can lead to SLUDGE syndrome. The species is sometimes mistaken for the deadly I. erubescens.

<i>Inocybe saliceticola</i> Species of fungus in the family Inocybaceae found in the Nordic countries

Inocybe saliceticola is a fungus found in moist habitats in the Nordic countries. The species produces brown mushrooms with caps of varying shapes up to 40 millimetres (1.6 in) across, and tall, thin stems up to 62 mm (2.4 in) long. At the base of the stem is a large and well-defined "bulb". The species produces unusually shaped, irregular spores, each with a few thick protrusions. This feature helps differentiate it from other species that would otherwise be similar in appearance and habit.

Leucocoprinus straminellus is a species of mushroom producing fungus in the family Agaricaceae. Like other Leucocoprinus species it may have originated in a tropical climate but now finds a home in plant pots, greenhouses and compost piles in many countries. Leucocoprinus straminellus is described as being similar to the more commonly known Leucocoprinus birnbaumii but it is smaller and a lighter shade of yellow with smaller spores that lack a germ pore. It is also described as being superficially similar to Leucocoprinus fragilissimus but slightly more robust with flesh that is less translucent.
