What You'll Learn
Yellow Fieldcap mushrooms are not psychedelic
Yellow Fieldcap mushrooms (Bolbitius titubans) are not psychedelic. They are, in fact, considered inedible due to their small size and thin flesh. This mushroom is also known as Bolbitius vitellinus and commonly as the sunny side up. It is a widespread species of mushroom found in North America and the UK. It grows on grass, dung, rotting straw, and manure.
The Yellow Fieldcap mushroom is quite distinctive, with a bright yellow cap when young, which fades to whitish, greyish, or pale brown as it matures. The cap is initially rounded, elliptical, or ball-like, and then becomes broadly convex and eventually nearly flat. The stem is whitish-yellow and very delicate. The gills are soft and fragile, and they change colour from whitish or pale yellow to rusty cinnamon or dark brown with age.
The Yellow Fieldcap mushroom has a very short lifespan, usually lasting only up to 24 hours. It typically appears after rain, especially in late spring and throughout the summer. Its rapid fruiting cycle is one of its notable characteristics. The mushrooms start as bright yellow, oval fruiting bodies and quickly develop into mature mushrooms with flattened caps and brown spores before falling to the ground.
While the Yellow Fieldcap mushroom is not psychedelic, its unique appearance and rapid life cycle make it an interesting species to observe in the wild.

They are also known as 'Egg Yolk Fungi'
The Yellow Fieldcap mushroom (scientific name: Bolbitius titubans) is also known as Egg Yolk Fungi due to its distinctive appearance. When young, this mushroom has a bright yellow, egg-shaped cap, which some people liken to an egg yolk or "fried egg on a stick". The mushroom's cap measures 1.5–7 centimetres (1⁄2–3 inches) across and grows on grass, woodchips, compost, and well-rotted dung. The stem is whitish-yellow and very delicate, measuring 2–6 millimetres (1⁄8–1⁄4 inches) wide. The gills are soft, fragile, and whitish or pale yellowish, maturing to a rusty cinnamon colour.
The Yellow Fieldcap is a short-lived mushroom, typically lasting a maximum of 24 hours. It usually appears two days after rainfall, from late spring throughout the summer. This species is widespread in North America and Europe but is generally regarded as inedible due to its small size and thin flesh. The edibility of the Yellow Fieldcap is unknown, and it is not typically consumed due to its insubstantial nature.
The name Bolbitius is derived from the Greek word "bolbos", meaning "bulbous", referring to the mushroom's egg-like shape. The specific epithet titubans means "staggering" or "wavering", describing the mushroom's tendency to lean and eventually fall in a slow, staggered manner. The Yellow Fieldcap was first described in 1789 by French mycologist Jean Baptiste Francois Pierre Bulliard, who named it Agaricus titubans. However, in 1838, Swedish mycologist Elias Magnus Fries reclassified it as Bolbitius titubans.
The Yellow Fieldcap has several similar-looking relatives, including Bolbitius aleuriatus, B. coprophilus, B. lacteus, and Conocybe apala. These mushrooms share similar characteristics and habitats, growing on grass, woodchips, and dung. However, the distinctive bright yellow cap and short life span make the Yellow Fieldcap a unique and fascinating species in the world of fungi.

They are inedible
The Yellow Fieldcap mushroom (Bolbitius titubans) is generally regarded as inedible. Its small size, thin flesh, and very short lifespan of a maximum of 24 hours mean there is little temptation to try eating this mushroom. In addition, the Yellow Fieldcap mushroom has a very rapid fruiting cycle, starting out as bright yellow, oval fruiting bodies that are noticeably wet. In a few hours, the pale-coloured stipes grow tall, and the caps flatten out and begin to fade in colour. The gills turn from pale yellow to dark brown, eventually producing brown spores before the mushroom falls to the ground. All this happens in less than a day.
The Yellow Fieldcap mushroom is also known as Bolbitius vitellinus or "Egg Yolk Fungus" due to its yellow colour when young. The mushroom's cap is 1.5–7 centimetres across and grows from egg-shaped to broadly convex, finally ending up nearly flat. The stem is 2–6 millimetres wide, whitish-yellow, and very delicate. The gills are fragile and soft, and they are free from the stem or narrowly attached. As the mushroom matures, the cap becomes pale brown and the gills turn a cinnamon colour.
The Yellow Fieldcap mushroom is a widespread species found in North America and the UK. It grows on grass, dung, rotting straw, manure, and wood chippings. The mushroom is commonly found on farmland, especially in well-manured fields. While it is not poisonous, its insubstantial nature and rapid lifecycle make it unappealing as a culinary ingredient.
It is important to note that consuming wild mushrooms without proper knowledge and expertise can be dangerous. Even experienced foragers sometimes make deadly mistakes. Always seek expert advice before consuming any wild mushroom.

They are short-lived, lasting a maximum of 24 hours
The Yellow Fieldcap mushroom, scientifically known as Bolbitius titubans, is a short-lived species, lasting a maximum of 24 hours from the time it fruits to when it falls to the ground and dies. It is also known as Bolbitius vitellinus and commonly as the sunny side up. It is a widespread species of mushroom found in North America and the UK. It is commonly found on farmland, especially in well-manured fields, and on rotting straw, hay, dung, grass, and wood chippings.
The Yellow Fieldcap mushroom has a rapid fruiting cycle, with bright yellow, oval fruiting bodies that are noticeably wet. Within a few hours, the pale-coloured stipes grow tall, and the caps flatten out and begin to fade in colour. The caps are initially bright yellow or yellow-brown with a yellowish centre and striations along the margin, but they fade to whitish or greyish with age. The gills, which are fragile and soft, are whitish or pale yellowish when young but turn dark brown with age, eventually producing brown spores.
The mushrooms typically appear two days after rain, usually in late spring and throughout the summer. They are small, with caps ranging from 1.5 to 7 centimetres across and stems that are 2 to 6 millimetres wide. Due to their small size and thin flesh, they are generally considered inedible. Their short lifespan and distinctive appearance make them a fascinating subject for observation and photography.
The Yellow Fieldcap mushroom's scientific name, Bolbitius titubans, is derived from the genus name Bolbitius, which means 'of cow dung', and the specific epithet titubans, which means 'staggering' or 'wavering'. This name reflects the mushroom's tendency to lean and eventually fall in a slow-motion stagger. While some may find their appearance intriguing, the Yellow Fieldcap mushroom's brief lifespan, insubstantial size, and inedible nature make them a mere curiosity rather than a culinary delight.

They grow on well-manured fields and rotting hay
The Yellow Fieldcap mushroom, scientifically known as Bolbitius titubans, is not a psychedelic mushroom. It is generally regarded as inedible. The name Bolbitius means 'of cow dung', but it is worth noting that the Yellow Fieldcap mushroom prefers well-rotted dung and tends to avoid fresh cow pats. It grows on well-fertilised soil, rotting straw, dung, and grass. When young, it has a yellow, egg-shaped cap, sometimes called the Egg Yolk Fungus. As it matures, the cap becomes pale brown with cinnamon gills. It is one of the shortest-living mushrooms, lasting a maximum of 24 hours and usually appears two days after rain.
While the Yellow Fieldcap mushroom may not be the magic mushroom you're looking for, there are several other psychedelic mushrooms that grow on well-manured fields and rotting hay. The Psilocybe semilanceata, commonly known as the Liberty Cap, is one such species. It grows from dead grass roots and is especially common in wet pastures where the grass roots form a heavy thatch. It can thrive in grazed fields but is not associated with animal dung. It is also found in lawns and playing fields in wet coastal areas. Psilocybe semilanceata is a common weed species of urban and suburban landscapes, sometimes growing in large quantities in recently established lawns and plantings in wood chip mulch or where the soils contain woody materials.
Psilocybe cyanescens, Psilocybe allenii, and Psilocybe ovoideocystidiata are three other psychedelic mushrooms of interest to magic mushroom hunters. They are small, typically growing no more than two to three inches tall, with chestnut brown caps, white stems, and dark purple spores. They are often found in urban landscapes, feeding on wood chips and manure piles.
Another species to consider is Panaeolus subbalteatus, which grows in very rich manured soils of newly laid lawns and landscaping. It can also be found in old leached horse manure and rotting straw around stables.
