What You'll Learn
Penny bun mushrooms reproduce via spores
Penny bun mushrooms, or boletus edulis, reproduce through the production and release of spores. This process occurs in the summer and autumn seasons. The spores are produced in the fruit bodies of the fungus, which are located above ground. The fruit body of the penny bun mushroom has a distinctive appearance, with a large brown cap that can reach up to 30 cm in diameter and a stout stipe, or stem, that is white or yellowish in colour.
The underside of the cap, where spores are produced, is composed of thin tubes that are 1 to 2 cm deep and whitish in colour when young. As the mushroom matures, these tubes gradually change colour, turning yellowish and eventually greenish-yellow. The spores mature and escape through the tube openings, or pores, which are initially white and fine but become larger and greenish-yellow as the mushroom ages.
The penny bun mushroom is characterised by its unique spore-bearing structure. Unlike other mushrooms that have gills, the penny bun features sponge-like pores on the underside of its cap. These pores play a crucial role in spore production and dissemination. As the mushroom matures, the pores enlarge and change colour, providing a visual indication of the spore's development.
The process of spore maturation and release is essential for the reproduction of penny bun mushrooms. The spores, carried by air currents, disperse and germinate in favourable conditions, initiating the growth of new penny bun mushroom mycelium. This reproductive strategy enables the fungus to propagate and establish itself in new locations.
In summary, penny bun mushrooms reproduce through the production and dissemination of spores. The distinctive cap and spore-bearing structures of the fungus facilitate this reproductive process. The maturation and release of spores contribute to the propagation and survival of penny bun mushrooms in their natural habitat.

Spores are produced on the underside of the cap
The Penny Bun mushroom, or Boletus edulis, is a type of fungus that produces spores on the underside of its cap. Unlike other mushrooms, which typically have gills on their undersides, the Penny Bun features a unique sponge-like pore system. These pores, which are initially white, gradually change to yellow and then to a greenish-yellow colour as the mushroom matures. This colour transformation indicates the maturation of the spores.
The cap of the Penny Bun mushroom is broad and reddish-brown, with a paler edge that fades to white near the margin. The underside of the cap is composed of thin tubes, approximately 1 to 2 cm deep, that serve as the site of spore production. These tubes are whitish in young mushrooms but mature to a greenish-yellow hue, mirroring the colour shift of the pores.
The Penny Bun mushroom's spore-bearing fruit bodies develop above ground during the summer and autumn seasons. The fruit body boasts a large brown cap that can occasionally reach an impressive diameter of 30 cm (12 inches) and, rarely, up to 40 cm (16 inches). The stipe, or stem, of the mushroom is thick and swollen, with a pale brown colour and a white network pattern on its upper portion.
The Penny Bun mushroom is a highly sought-after edible variety, prized for its flavour and texture. It is commonly found in woodlands, particularly those with oak, birch, beech, and coniferous trees. Foragers and chefs alike value the Penny Bun for its culinary versatility and contribution to delicious dishes.

Spores are released through tube openings when mature
The Penny Bun mushroom, or Boletus edulis, is a type of fungus that reproduces through the production and release of spores. This process occurs in the summer and autumn seasons, when the fungus produces spore-bearing fruit bodies above ground.
The fruit body of the Penny Bun mushroom has a distinctive appearance, with a large brown cap that can reach up to 30 cm in diameter and a stout stipe, or stem, that is white or yellowish in colour. The underside of the cap, where many other mushrooms have gills, is characterised by its sponge-like pores, which are the site of spore production. These pores are initially white and appear stuffed with cotton, but as they mature, they change colour to yellow and eventually to a greenish-yellow or olive green, at which point the spores are ready for release.
The Penny Bun mushroom's spores are located within the tubes extending downward from the underside of the cap. These tubes are white and become yellowish and then greenish as the mushroom ages. When the spores reach maturity, they are released through the tube openings, or pores. This release results in the escape of spores into the surrounding environment, facilitating the dispersal and potential germination of the Penny Bun mushroom's spores.
The pore surface of the fruit body plays a crucial role in the maturation and release of spores. Initially, when the mushroom is young, the pore surface is whitish. However, as the mushroom ages, this surface undergoes a colour transformation, maturing to a greenish-yellow hue. This colour change serves as a visual indicator of the mushroom's developmental stage and the impending release of spores through the tube openings.

The colour of the spores changes from white to yellow to green as the mushroom ages
The Penny Bun mushroom, or Boletus edulis, is a highly sought-after edible mushroom. It is also known as the Cep, Porcino, or Penny-bun Bolete. This fungus is a woodland species, commonly found in open mixed deciduous woodland, in close association with oak, birch, beech, and coniferous trees. It is fairly common in the UK and found throughout Britain and Ireland, mainland Europe, Asia, and the USA.
The Penny Bun mushroom has a unique reproductive process that results in the colour change of its spores. When young, the gills or pores of the mushroom are white, appearing as if stuffed with cotton. These gills are the site of spore production and are located on the underside of the cap. As the mushroom ages, the gills undergo a transformation, changing colour from white to yellow and eventually turning green and spongy. This colour change is accompanied by a maturation of the spores, which escape through the tube openings or pores.
The white gills of young Penny Bun mushrooms are whitish or pale cream in colour, often with a glossy surface. They are fine pores that appear as if stuffed with cotton, which are actually mycelia. Over time, as the mushroom matures, these pores change colour, turning yellow and then gradually becoming olive green. This colour change is due to the maturation of the spores, which start out white and become greenish-yellow with age.
The colour transformation of the spores is not only visually striking but also serves a functional purpose. The white gills of young Penny Bun mushrooms are not yet mature and are in the process of developing. The white colour indicates that the spores are not yet ready for dispersal. As the gills mature and turn yellow, the spores inside are also maturing and preparing for release. The final green colour of the gills signals that the spores have reached full maturity and are ready for dispersal through the tube openings or pores.
The colour change of the spores from white to yellow to green is a natural process that occurs as the Penny Bun mushroom ages. This transformation not only adds to the visual appeal of the mushroom but also ensures the successful reproduction of the fungus. Foragers and cooks are advised to pick Penny Bun mushrooms when they are fully developed but still young, as older mushrooms are more likely to contain maggots. However, some people simply remove the maggots and use the middle-aged mushrooms in their cooking, even when the gills have turned greenish-yellow.
