Pleurotus populinus, the aspen oyster mushroom, is a gilled fungus native to North America. It is found on dead wood of aspen and cottonwood trees (genus Populus ). Although morphologically similar to Pleurotus ostreatus and Pleurotus pulmonarius , it has been shown to be a distinct species incapable of cross-breeding. [1] P. populinus is reported to be edible. [2] Unlike P. ostreatus, which fruits in the autumn and winter, P. populinus fruits in late spring and summer. [2]

Taxonomy

The species was first described scientifically by mycologists Oswald and Orson K. Miller in 1993 with a provisional name. [3] This original naming was invalid according to several sections of the International Code of Botanical Nomenclature, [4] so it was republished in 1997. [5]

Description

The fruit bodies have oyster shell-shaped to fan-shaped caps that are 4–19 cm (1.6–7.5 in) broad by 4–13 cm (1.6–5.1 in) wide. The cap margin is initially rolled inward, becomes finely scalloped in age. The color ranges from ivory white to pinkish buff to orange-grey. The gills are somewhat decurrent, running a short ways down the stipe. They are 3–10 mm broad, white to cream in color, and have two sets of intervening lamellulae (short gills). [6]

The spore print is buff. Spores are thin-walled with a narrowly elliptical to oblong shape, and dimensions of 9–15 by 3–5  μm. The basidia are club-shaped, four-spored, and measure 20–27 by 5–6 μm. [6]

Habitat and distribution

Pleurotus populinus fruit bodies grow singly to numerous—often arranged in overlapping clusters—on the rotting stumps, logs, and limbs of hardwoods. Preferred substrates include aspen and black cottonwood. It is found in the northern United States and Canada, and in mountainous regions of western North America. It is a common species in its range, where it fruits in June and July. [6]

<i>Pleurotus ostreatus</i> Species of fungus

Pleurotus ostreatus, the oyster mushroom, oyster fungus, hiratake, or pearl oyster mushroom is a common edible mushroom. It is one of the more commonly sought wild mushrooms, though it can also be cultivated on straw and other media.

<i>Pleurotus</i> Genus of fungi

Pleurotus is a genus of gilled mushrooms which includes one of the most widely eaten mushrooms, P. ostreatus. Species of Pleurotus may be called oyster, abalone, or tree mushrooms, and are some of the most commonly cultivated edible mushrooms in the world. Pleurotus fungi have also been used in mycoremediation of pollutants, such as petroleum and polycyclic aromatic hydrocarbons.

<i>Chroogomphus vinicolor</i> Species of fungus

Chroogomphus vinicolor, commonly known as the wine-cap Chroogomphus or the pine spike, is a species of mushroom in the family Gomphidiaceae. Found in North America and the Dominican Republic, mushrooms grow on the ground under pine trees. Fruit bodies have reddish-brown, shiny caps atop tapered stems. The gills are thick, initially pale orange before turning blackish, and extend a short way down the length of the stem. Although the mushroom is edible, and sold in local markets in Mexico, it is not highly rated. Distinguishing this species from some other similar Chroogomphus species is difficult, as their morphology is similar, and cap coloration is too variable to be a reliable characteristic. C. vinicolor is differentiated from the European C. rutilus and the North American C. ochraceus by the thickness of its cystidial walls.

<i>Neolentinus ponderosus</i> Species of fungus

Neolentinus ponderosus, commonly known as the giant sawgill, or ponderous lentinus, is a species of fungus in the family Gloeophyllaceae. Found in western North America, it was originally described in 1965 as a species of Lentinus by American mycologist Orson K. Miller.

<i>Omphalotus nidiformis</i> Species of bioluminescent fungus in the family Marasmiaceae

Omphalotus nidiformis, or ghost fungus, is a gilled basidiomycete mushroom most notable for its bioluminescent properties. It is known to be found primarily in southern Australia and Tasmania, but was reported from India in 2012 and 2018. The fan or funnel shaped fruit bodies are up to 30 cm (12 in) across, with cream-coloured caps overlain with shades of orange, brown, purple, or bluish-black. The white or cream gills run down the length of the stipe, which is up to 8 cm (3 in) long and tapers in thickness to the base. The fungus is both saprotrophic and parasitic, and its fruit bodies are generally found growing in overlapping clusters on a wide variety of dead or dying trees.

<i>Pleurotus pulmonarius</i> Species of mushroom

Pleurotus pulmonarius, commonly known as the Indian oyster, Italian oyster, phoenix mushroom, or the lung oyster, is a mushroom very similar to Pleurotus ostreatus, the pearl oyster, but with a few noticeable differences. The caps of pulmonarius are much paler and smaller than ostreatus and develops more of a stem. P. pulmonarius also prefers warmer weather than ostreatus and will appear later in the summer. Otherwise, the taste and cultivation of the two species is generally described as largely the same. Another similar species, North America's Pleurotus populinus, is restricted to growing on aspen and cottonwood.

<i>Lactarius subflammeus</i> Species of fungus

Lactarius subflammeus, commonly known as the orange milk cap, is a species of fungus in the family Russulaceae. It is found in western North America in the late summer and fall and is especially common in the Pacific Northwest, where it grows on the ground near conifers like pine and spruce. The brightly colored fruit bodies, which are slimy or sticky, have scarlet caps when young that soon fade to brilliant orange. The stem—typically longer than the width of the cap—is also bright orange but the gills are whitish. The mushroom secretes a whitish latex when it is cut or injured.

<i>Lactarius alnicola</i> Species of fungus

Lactarius alnicola, commonly known as the golden milkcap, is a species of fungus in the family Russulaceae. The fruit bodies produced by the fungus are characterized by a sticky, vanilla-colored cap up to 20 cm (7.9 in) wide with a mixture of yellow tones arranged in faint concentric bands. The stem is up to 5 cm (2.0 in) long and has yellow-brown spots. When it is cut or injured, the mushroom oozes a white latex, which has an intensely peppery taste. The acrid taste of the fruit bodies renders them unpalatable. The fungus is found in the western United States and Mexico, where it grows in mycorrhizal associations with various coniferous trees species, such as spruce, pine and fir, and deciduous species such as oak and alder. It has also been collected in India. Two varieties have been named: var. pitkinensis, known from Colorado, and var. pungens, from Michigan.

Mock oyster mushrooms have a strong, unpleasant odor, and are regarded as inedible though nonpoisonous.
