Gymnopilus sapineus, commonly known as the scaly rustgill or common and boring gymnopilus, [2] is a small and widely distributed mushroom which grows in dense clusters on dead conifer wood. It has a rusty orange spore print and a bitter taste. This species does not stain blue and lacks the hallucinogen psilocybin.

Taxonomy

Speciation in Gymnopilus is not clearly defined. [3] This is further complicated by the macroscopic morphological and ecological similarities between members of the G. sapineus complex such as G. penetrans and G. nevadensis. Michael Kuo explicates upon this by speaking of the arbitrary distinction made between G. sapineus and G. penetrans made by Elias Magnus Fries. [4] He at first labeled G. penetrans to merely be a form of G. sapineus in 1815, but then recanted and labeled them separate in 1821.

Description

This mushroom is often mistaken for G. luteocarneus which grows on conifers and has a smoother and darker cap. Another lookalike is G. penetrans which grows in the same habitat and has minor microscopic differences. [4]

Cap: The cap is 2–8 cm (343+18 in) across, is convex to flat, and is golden-yellow to brownish orange, [5] darker at the center with a dry scaly surface which is often fibrillose and may have squamules. The cap margin is inrolled at first and curves outward as it matures, becoming almost plane and sometimes developing fibrillose cracks in age. [5] The flesh is yellow [5] to orange and delicate when compared to larger and firmer members of Gymnopilus , such as G. junonius .

Gills: The gills are crowded, yellow at first, turning rusty orange as the spores mature, with adnate attachment.

Microscopic features: Gymnopilus sapineus spores are rusty orange [5] to rusty brown, elliptical, rough, and 7–10 x 4–6  μm.

Stipe: The stipe is 3–7 cm (1+182+34 in) long and 0.5–1 cm thick. [5] It has either an equal structure, or becomes thinner near the base. It is light yellow, bruising rusty brown. The stipe has an evanescent veil which often leaves fragments on the upper part of the stipe [5] or the margin of young caps.

Taste and odor: G. sapineus sometimes tastes bitter, and it has a mild, [5] fungoid or sweet smell.

Toxicity: The species is nonpoisonous, but considered inedible. [6]

<i>Gymnopilus junonius</i> Species of fungus

Gymnopilus junonius is a type of mushroom-forming fungus in the family Hymenogastraceae. Commonly known as the spectacular rustgill, this large orange mushroom is typically found growing on tree stumps, logs, or tree bases. Some subspecies of this mushroom contain the neurotoxic oligoisoprenoid gymnopilin.

<i>Gymnopilus</i> Genus of fungi

Gymnopilus is a genus of gilled mushrooms within the fungal family Strophariaceae containing about 200 rusty-orange spored mushroom species formerly divided among Pholiota and the defunct genus Flammula. The fruit body is typically reddish brown to rusty orange to yellow, medium to large, often with a well-developed veil. Most members of Gymnopilus grow on wood but at times may appear terrestrial if the wood is buried or decomposed. Members of Pholiota and Cortinarius are easy to confuse with Gymnopilus. Pholiota can be distinguished by its viscid cap and duller spores, and Cortinarius grows on the ground. Beginners can confuse Gymnopilus with Galerina, which contains deadly poisonous species.

<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.

Fruit bodies (mushrooms) are robust, with caps up to 18 cm in diameter, atop thick stipes 5–12 cm long. Mushrooms are non-toxic, but is so bitter as to be inedible. The mushroom flesh has a very strong bluing reaction when cut or damaged. and forms mycorrhizal relationships, primarily with conifers. It can be differentiated from similar boletes by its cap color and non-reticulate stipe.

It has a cosmopolitan distribution, and grows on dead wood, stumps, trunks, and branches of both deciduous and coniferous trees. Its fruit body is up to 10 cm tall, made of multiple slender, compact, and vertical parallel branches. Its color is typically light tan to vinaceous-brown. All parts of the mushroom will bruise when handled. There are several lookalike corals that can usually be distinguished from R. stricta by differences in coloration, bruising reaction, or microscopic features. The fungus is inedible due to its unpleasant odor and bitter taste.

<i>Pholiota nubigena</i> Species of fungus

Pholiota nubigena, commonly known as the gastroid pholiota or the bubble gum fungus, is a species of secotioid fungus in the family Strophariaceae. It is found in mountainous areas of the western United States, where it grows on rotting conifer wood, often fir logs. It fruits in spring, often under snow, and early summer toward the end of the snowmelt period in high mountain forests. Fruit bodies appear similar to unopened mushrooms, measuring 1–4 centimetres tall with 1–2.4 cm diameter caps that are whitish to brownish. They have a short but distinct whitish stipe that extend through the internal spore mass (gleba) of the fruit body into the cap. The gleba consists of irregular chambers made of contorted gills that are brownish in color. A whitish, cottony partial veil is present in young specimens, but it often disappears in age and does not leave a ring on the stipe.

<i>Pholiota astragalina</i> Species of fungus

Pholiota astragalina, commonly known as the pinkish-orange pholiota, is a species of fungus in the family Strophariaceae. It was first described scientifically in 1821 by Elias Magnus Fries as a species of Agaricus. Rolf Singer transferred it to the genus Pholiota in 1951. The fruitbodies of the fungus have pinkish-orange caps measuring 2–5.5 cm in diameter. The flesh is orange, blackening in age, with a bitter taste. They produce a reddish-brown spore print, causing it to be placed in its genus rather than Hypholoma, which it resembles. The spores are oval to elliptical, smooth with thin walls, and measure 5–7 by 4–4.5 µm. In North America, the fungus is found in the United States and Canada. In Europe, it has been recorded from France, Sweden, and Switzerland. Its mushrooms usually grow singly or in small clusters, sometimes on conifer logs.
