Boletes are a diverse group of mushrooms that are typically recognised by their spongy, porous undersides, as opposed to the gills found on other mushrooms. However, some bolete species do have gills. These species are known as gilled boletes, with Phylloporus rhodoxanthus being the most common. This unique species looks like a typical bolete but with gills.

Bolete mushrooms are characterised by their spongy surface, or pores, instead of gills
The underside of a bolete mushroom cap has a spongy surface with pores, which is unique when compared to the gills typically found on mushrooms. This feature sets them apart and makes them easily identifiable as a group in the wild. The pores are connected to numerous tiny round tubes inside the cap, and the inner walls of these tubes produce spores, which are released from the pores to allow bolete mushrooms to multiply.
While most boletes have pores, there are some species that have gills. For example, the Phylloporus rhodoxanthus, or gilled bolete, is a species of bolete mushroom that has gills instead of pores. It has a reddish pileus and yellow, decurrent gills. Mycologists originally thought that this species represented a transitional stage between gilled and pored mushrooms, but this hypothesis was not widely supported due to conflicting microscopic evidence.
Bolete mushrooms have a variety of colours and can be identified by their thick or bulbous stems and caps. They include both edible and poisonous varieties, with the poisonous types usually having red pores under the cap. Bolete mushrooms are a good source of antioxidants and have been shown to have potential anticancer effects.

However, some bolete species do have gills, such as Phylloporus rhodoxanthus
Boletes are a diverse group of mushrooms that belong to the Boletaceae family. They are characterised by their unique fruiting bodies, which consist of a cap, stem, and pore surface. Unlike mushrooms with gills, boletes have a spongy surface on the underside of their caps, known as pores. This feature sets them apart and makes them readily identifiable as a group in the wild. They are commonly found in woodlands and forests, forming symbiotic relationships with trees and shrubs.
The existence of gilled bolete species like Phylloporus rhodoxanthus challenges traditional classifications of mushrooms. Initially, distinctions between mushrooms were made based on macroscopic features, such as the presence of gills or pores. However, with advances in molecular systematics, taxonomists are now making major revisions in mushroom categorisation. Analyses of mushroom genes have revealed surprising evolutionary links between groups previously thought to be distantly related.
The presence of gills in some bolete species, such as Phylloporus rhodoxanthus, highlights the complexity and diversity within the Boletaceae family. While most boletes are characterised by their spongy pore surface, the existence of gilled variants underscores the need for careful identification and classification within this group of mushrooms.

Boletes are a diverse group of mushrooms that can be poisonous or edible
Boletes are a diverse group of mushrooms that belong to the Boletaceae family. They are characterised by their unique fruiting bodies, which consist of a cap, stem, and pore surface. Unlike mushrooms with gills, boletes typically have a spongy surface on the underside of their caps, known as pores. This feature makes them stand out and easily identifiable in the wild. They are commonly known as fleshy pore fungi and are found worldwide, except for Antarctica.
While most boletes have pores, there are some species that possess gills. For instance, the Phylloporus genus, which belongs to the Boletales order, has gills instead of pores. The most common edible gilled species is Phylloporus rhodoxanthus, which is widely distributed across North America.
Boletes are reasonably safe for human consumption, as none of them are known to be deadly to adults. Some popular edible bolete species include the King Bolete (Boletus edulis), Spring King, Queen, Bay Bolete, and the Orange Birch Bolete. The King Bolete is one of North America's most highly prized edible species, known for its nutty flavour and meaty texture.
However, it is important to note that not all boletes are edible. Some boletes are toxic and can cause gastrointestinal issues if consumed. The rule of thumb is to avoid boletes with red caps and pores that stain blue when cut, as these are likely to be toxic. Additionally, some boletes, like the bitter bolete, are unpalatable due to their bitter taste.
Identifying boletes can be a challenging task, even for experienced mycologists. While certain characteristics can help with identification, such as the presence of pores or gills, colour, and texture, molecular techniques are now being used to accurately classify mushroom species.

They are commonly found in woodlands and forests, forming symbiotic relationships with trees
Boletes are a diverse group of mushrooms that are commonly found in woodlands and forests. They are characterised by their unique fruiting bodies, which consist of a cap, stem, and pore surface. Unlike typical mushrooms, the underside of the cap of a bolete mushroom does not have gills. Instead, it has a spongy surface with pores. These pores are connected to numerous tiny round tubes inside the cap, and the inner walls of these tubes produce spores, aiding in the multiplication of bolete mushrooms. The presence of pores is a key feature that sets boletes apart from other mushrooms and makes them relatively easy to identify in the wild.
Boletes are often found near or under specific trees, and they form symbiotic relationships with these trees. They share nutrients with the roots of the trees, creating a mutually beneficial arrangement. This relationship is an important aspect of their ecological role in woodlands and forests. Boletes are generally categorised into three main groups or genera: Boletus, Leccinum, and Suillus.
While most boletes do not have gills, there are some rare exceptions. For example, the Phylloporus rhodoxanthus, commonly known as the Gilled Bolete, is a species of bolete that exhibits gills. This particular species has a reddish cap and yellow gills that become marred with brownish spots as the mushroom ages. The gills are thick, widely spaced, and often exhibit forks and cross-veins, especially where they meet the stipe. The presence of gills in this bolete species initially confused mycologists who thought it represented a transitional stage in the evolution of gilled mushrooms. However, molecular systematics and evolutionary analyses have revealed surprising evolutionary links, challenging traditional taxonomic classifications.
In addition to their unique cap characteristics, boletes can be identified by their overall appearance and colour. They are usually large, fleshy mushrooms that come in a variety of colours, with a thick or bulbous stem and no ring, except for some species in the Suillus group. Some boletes have white pores, while others may have yellow or red pores. It is important to note that boletes with red pores, such as those in the Rubroboletus genus, are often dangerously poisonous. Therefore, proper identification is crucial before consuming any wild mushrooms.

Boletes are typically large fleshy mushrooms that come in a variety of colours
The Boletus family is a large genus of mushrooms that until recently was split into a few smaller families, the main three being Boletus, Leccinum, and Suillus. The Boletus genus was originally broadly defined and described by Carl Linnaeus in 1753, containing all pored mushrooms. Since then, other genera have been defined, and old names such as Leccinum and Suillus have been resurrected or redefined.
Boletes are commonly found in woodlands and forests, forming symbiotic relationships with trees and shrubs. They do not grow on composting material. Instead, they share nutrients with the roots of specific trees. Some boletes are edible and considered a delicacy, such as the porcini (Boletus edulis), also called penny buns. Penny buns have white pores, a dark brown cap, and a thick whitish stem with a net-like covering that is lighter than the stem. Other edible boletes include Leccinum species, which are scaber-stalk or rough-stemmed mushrooms with white pores under a yellowish or reddish cap, and Suillus species, such as slippery jacks, which have narrow stems and slippery or sticky caps with greyish-white to yellow pores.
It is important to note that some boletes are poisonous or unpleasant to eat. Boletes with red pores under the cap, such as those in the Rubroboletus genus, should be avoided as they can be dangerously toxic. Most poisonous boletes will cause extreme gastrointestinal issues but are not deadly.
