Mushrooms are fascinating organisms that exhibit various growth habits, and one such pattern is gregarious mushrooms. Gregariousness, derived from the Latin word gregarius, refers to the tendency of animals or plants to live or grow in groups or clusters. In the context of mushrooms, gregariousness describes the phenomenon where mushrooms fruit and grow in groups, exhibiting a social behaviour of sorts. While some mushrooms are found as individuals, many species tend to occur in groups of two or more, creating a unique dynamic in the fungal kingdom. This growth pattern is an intriguing aspect of mycology, the study of mushrooms, and plays a significant role in how we understand and collect these fascinating organisms.

Gregarious mushrooms grow in groups, not alone
Mushrooms are fascinating organisms that exhibit diverse growth habits, and one such intriguing pattern is their tendency to be gregarious. Gregarious mushrooms stand out for their propensity to grow in groups rather than in isolation. This behaviour is quite common among mushrooms, as they often enjoy the company of their own kind, much like social animals that move in flocks or herds.
The gregarious nature of mushrooms is a fascinating aspect of mycology, the study of fungi. While some mushrooms are found as solitary individuals, many others exhibit a strong preference for companionship. Gregarious mushrooms form characteristic relationships with each other, creating unique patterns in nature. This behaviour is in stark contrast to mushrooms that always fruit alone, which can make them less appealing to mycologists for scientific study as they may not be substantial enough for permanent collections.
The Agaricus bitorquis, commonly known as the torq or banded agaric, is an excellent example of a gregarious mushroom. This edible species can be found growing in small groups in gardens, roadsides, and pavements, often pushing through asphalt and slabs. Another mushroom that displays gregarious behaviour is Clitopilus prunulus, also known as the miller or sweetbread mushroom. It can be found growing solitary or gregariously in open areas of conifer/hardwood forests, showcasing its adaptability.
Gregarious mushrooms are not just a curiosity of nature but also hold significant value. They are often sought-after by mushroom cultivators, as seen with Agaricus bitorquis, which has attracted interest due to its resistance to viral diseases, higher temperature tolerance, and better bruising resistance compared to standard button mushrooms. Additionally, gregarious mushrooms can form impressive displays in nature, such as the Cortinarius flabellus, which can be found growing in large groups over a fairly large area, almost like they are growing in "troops".
While gregarious mushrooms grow in groups, it is important to distinguish them from "cespitose" mushrooms. Cespitose mushrooms, like the Gymnopus acervatus, grow in extremely tight clusters, with their stipes arising from a common origin. In contrast, gregarious mushrooms fruit in groups but occur as distinct individuals without a common base. This distinction is essential in understanding the nuances of mushroom growth habits and their fascinating world.

They are characterised by their grouping, not as individuals
Mushrooms are typically characterised as "gregarious", meaning they grow in groups or clusters. The term "gregarious" is derived from the Latin "gregarius", meaning "going in flocks or herds". While some mushrooms do grow individually, most are found in groups of two or more, with some species always fruiting in groups.
Gregarious mushrooms do not arise from a common base, but rather grow in proximity to one another. This is in contrast to "cespitose" mushrooms, which grow in tight clusters with their stipes arising from a common origin. An example of a cespitose mushroom is Mycena leaiana, commonly found in eastern North America on dead hardwood logs.
The growth habit of mushrooms can vary, and some species may be found growing either individually or in groups. For example, Agaricus bitorquis, commonly known as torq or pavement mushroom, can be found growing solitary or in small groups. On the other hand, some species always seem to fruit alone.
The gregarious nature of mushrooms is not limited to a particular species, but rather a characteristic that is observed across various types of mushrooms. For instance, the Clitopilus prunulus mushroom, also known as the miller or sweetbread mushroom, can grow solitary or gregariously in open areas of conifer/hardwood forests.
In summary, while some mushrooms do grow individually, the majority are characterised by their grouping, with most species exhibiting some level of gregariousness in their growth habit.

Gregarious mushrooms fruit in groups, but not from a common base
Mushrooms vary in their growth habits. Some are found as individuals, but most occur in groups of two or more. Gregarious mushrooms, for instance, fruit in groups but are distinct individuals that do not share a common base. This is in contrast to "cespitose" mushrooms, which grow in tight clusters with stipes arising from a common origin.
Gregarious mushrooms, such as Clitopilus prunulus (commonly known as the miller or sweetbread mushroom) and Agaricus bitorquis (known as torq, banded agaric, or pavement mushroom), can be found growing in small groups in open areas of conifer/hardwood forests, gardens, and roadsides. These mushrooms are gregarious because they exhibit a social tendency to grow in groups or clusters, similar to how gregariousness in animals refers to their social behaviour of living or moving in flocks or herds.
The growth habit of gregarious mushrooms, where they fruit in groups but not from a common base, is an interesting aspect of mycology. Mycologists often refer to such large groups of mushrooms growing together as "troops". This growth pattern is distinct from that of cespitose mushrooms, which form very tight clusters with shared stipes.
While collecting mushrooms for scientific study, it is common to come across single fruiting bodies. However, due to the rapid deterioration of small mushrooms, collectors often prioritize finding species that typically fruit in groups, like gregarious mushrooms, to ensure they have enough material for study and permanent collection.
In conclusion, gregarious mushrooms exhibit a unique growth pattern where they fruit in groups, each with its own base. This sets them apart from cespitose mushrooms, which arise from a common origin. Understanding the gregarious nature of certain mushrooms is essential for both scientific study and mushroom foraging, as it helps predict where and how to find these fungi in the wild.

Examples include Clitopilus prunulus and Agaricus bitorquis
In the context of mushrooms, the term "gregarious" describes the manner in which certain species grow. Gregarious mushrooms grow in groups, either in clusters or in lines. This is in contrast to solitary mushrooms, which grow individually and away from other mushrooms.
Agaricus bitorquis
Agaricus bitorquis, commonly known as torq, banded agaric, spring agaric, banded agaricus, urban agaricus, or pavement mushroom, is a mushroom that can be found growing gregariously in nature. It is an edible white mushroom similar to the common button mushroom and is occasionally found throughout North America, Europe, Asia, and Australia. Agaricus bitorquis grows in gardens, roadsides, and pavements, often pushing through asphalt and slabs from its subterranean habitat.
Clitopilus prunulus
Clitopilus prunulus, commonly referred to as the Miller or the Sweetbread Mushroom, is another example of a gregarious mushroom. It is an edible pink-spored basidiomycete mushroom found in grasslands and open areas of conifer/hardwood forests in Europe and North America. Clitopilus prunulus has a grey to white cap and decurrent gills. It typically grows in the summer and autumn, fruiting shortly after the fall rains.
It is important to note that while Clitopilus prunulus is edible, it closely resembles the poisonous Clitocybe rivulosa (Fool's Funnel). Therefore, novice foragers should exercise caution when identifying and consuming this mushroom to avoid accidental poisoning.

The term gregarious comes from the Latin 'gregarius', meaning 'going in flocks or herds'
The term "gregarious" is used to describe mushrooms that grow in groups or clusters, as opposed to those that grow in isolation. The word is derived from the Latin "gregarius", which means "going in flocks or herds". In the context of mushrooms, gregarious describes the growth habit of certain species, which tend to form groups of two or more, rather than growing as individuals.
While most mushrooms are gregarious, there are some species that consistently fruit alone. These solitary mushrooms are less likely to be collected for scientific study because they tend to deteriorate quickly. Mycologists often pass over these "singles" because, by the time they are brought back to the laboratory, there may be little of the specimen left for permanent collection.
The Clitopilus prunulus, also known as the miller or the sweetbread mushroom, is an example of a species that can grow either solitarily or gregariously. This mushroom is found in grasslands in Europe and North America, typically in open areas of conifer or hardwood forests. It fruits shortly after the fall rains and can be identified by its grey to white cap and decurrent gills.
Another example of a gregarious mushroom is the Agaricus bitorquis, commonly known as the torq, banded agaric, or pavement mushroom. This species can be found growing in small groups in gardens and at roadsides, often pushing through asphalt and slabs. Agaricus bitorquis is an edible mushroom with a typical "mushroomy" taste, although specimens collected from the wild may be gritty due to its subterranean habitat.
In summary, the term "gregarious" in the context of mushrooms refers to species that grow in groups or clusters, as opposed to those that grow in isolation. The etymology of the word, stemming from the Latin "gregarius", reflects this social aspect of their growth habit, mirroring the way flocks or herds of animals come together.
