Leucocoprinus venezuelanus is a species of mushroom producing fungus in the family Agaricaceae. [1] [2]
It was first described in 1961 by the British mycologist Richard William George Dennis who classified it as Leucocoprinus venezuelanus. [3]
Leucocoprinus venezuelanus is a small dapperling mushroom with thin (1mm) white flesh which is unchanging in colour.
Cap: 2-3.5m wide when expanded to its full campanulate (bell shaped) or umbonate shape with very thin and fragile flesh. The surface colour is described as greyish orange and brownish orange in the central disc however as these colours are cited from the 1967 Methuen Handbook of Colour [4] which is out of print and virtually inaccessible today they are hard to convert into modern colour descriptions. As the cap expands the coloured surface breaks up into tiny granular scales against a white background with grooved striations (sulcate-striate) around the cap edges. Gills: Free, close and white. Stem: 3–4 cm tall and 1-2mm thick tapering upwards from a slightly bulbous base. The interior is hollow and the surface is white but it may discolour brown when handled with a pale brown colouring on the lower stem below the ring. The thin, membranous stem ring is located towards the top of the stem (superior) but may disappear, it is described as white or white on the top and brownish below. The stem detaches easily from the cap. Spores: Ovoid to ellipsoid. Dextrinoid. 6-8.5 x 4-5.5 μm. Smell: Floury (farinaceous). [3] [5]
L. venezuelanus is scarcely recorded and little known. The specimens described by Dennis were found growing on the ground near Caracas, Venezuela. [3] The British mycologist David Pegler examined specimens found on a dead stump on Santa Cruz Island in the Galápagos. [6]
It has also been reported from the Democratic republic of the Congo and a 2003 study documented this species growing in Kerala state, India where they were found growing scattered on soil in a tropical botanic garden. [5]
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.
Lactarius vietus is a species of fungus in the family Russulaceae, first described by Elias Magnus Fries. It produces moderately sized and brittle mushrooms, which grow on the forest floor or on rotting wood. The flattened-convex cap can vary in shape, sometimes forming the shape of a wide funnel. It is typically grey, but the colour varies. The species has crowded, light-coloured gills, which produce white milk. The spore print is typically whitish, but also varies considerably. The mushrooms typically have a strong, acrid taste and have been described as inedible, but other authors have described them as consumable after boiling. L. vietus feeds by forming an ectomycorrhizal relationship with surrounding trees, and it favours birch. It grows in autumn months and is fairly common in Europe, North America and eastern Asia.
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.
Leucocoprinus brebissonii is a species of mushroom producing fungus in the family Agaricaceae. It is commonly called the skullcap dapperling due to its distinctive pattern on the cap. This mushroom was only thought to be found in Europe but it has since been observed in the Pacific Northwest and may also be found in Asia.
Leucocoprinus fragilissimus, commonly known as the fragile dapperling, is a species of gilled mushroom in the family Agaricaceae.
Leucocoprinus cretaceus is a species of mushroom producing fungus in the family Agaricaceae. It is likely tropical in origin although it was first documented in Europe where it was often found growing in greenhouses and bark beds. However many early observations conflate this species with Leucocoprinus birnbaumii or Leucocoprinus cepistipes despite sharing only some superficial similarities. This fungus is quite versatile even for a saprotroph and is often found growing in clusters on woodchips, sawdust and compost heaps as well as directly from the ground or on trees. It may also appear in plant pots and greenhouses in colder countries in which it is not well equipped to survive outside.
Aureoboletus betula is a species of mushroom producing fungus in the family Boletaceae. It is commonly known as the Shaggy Stalked Bolete.
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.
