Truffles and mushrooms are both fungi, but they are not the same. They differ in terms of their growth patterns, appearance, and potency. While mushrooms grow above ground in a variety of environments, truffles are subterranean fungi that grow in wild forests a few months each year. Truffles are considered a delicacy and are native mainly to temperate regions, whereas mushrooms are versatile and can be eaten raw, sautéed, baked, grilled, etc.

What You'll Learn
Truffles and mushrooms are both fungi
Truffles are a type of subterranean fungus that grows underground in symbiotic relationships with the roots of certain trees, such as oak and pine. They are native mainly to temperate regions and are highly prized as a culinary delicacy for their earthy aroma and flavour. Truffles have a unique method of spore dispersal. Unlike mushrooms, truffles produce spores underground, and these spores are generally spread through animal ingestion and excretion. This means that an animal will eat the truffle and then deposit the spores in a new location through defecation. This method of spore dispersal is one of the key differences between truffles and mushrooms.
Mushrooms, on the other hand, typically grow above ground in a variety of environments and can be easily cultivated. They are the above-ground fruit bodies that release spores into the air, which are then dispersed by wind, rain, or animals. Mushrooms are versatile in their culinary applications and can be eaten raw, sautéed, baked, grilled, or used in various dishes.
While truffles and mushrooms are both fungi, they belong to different genera within the kingdom. Truffles are mainly from the genus Tuber, while mushrooms, such as button mushrooms, belong to the genus Agaricus. Oyster mushrooms are from the genus Pleurotus, and chanterelles are from the genus Cantharellus.
In summary, truffles and mushrooms are both types of fungi, but they differ in their growth patterns, appearance, spore dispersal methods, and scientific classifications. Truffles are subterranean fungi with unique culinary and aromatic properties, while mushrooms are versatile above-ground fungi with a range of culinary applications.

Truffles are tubers, mushrooms are not
Truffles and mushrooms are closely related, but they are not the same. Truffles are a type of fungus that grows underground, forming symbiotic relationships with the roots of certain trees. They are part of the Tuberaceae family and have a distinct aroma. Mushrooms, on the other hand, are independent organisms that grow above ground and have a cap and stem. They are also fungi that derive nourishment from the external environment by absorbing it through the walls and decomposing organic material present in the soil.
While truffles are often considered tubers due to their name and shape, they are not true tubers. Tubers are modified plant stems that take on a globular shape, and they are used by plants to store nutrients for survival during winter and reproduction. Truffles, on the other hand, are fungi that grow underground and have a unique mode of reproduction. They reproduce by forming spores that are spread by animals, whereas tubers reproduce through buds on their surface.
The confusion about the true nature of truffles is understandable. Truffles belong to the Tuberaceae family, and their scientific name is "Tuber". This similarity in names can lead to the incorrect conclusion that truffles are tubers. However, the Tuberaceae family refers to species that are born and grow underground with a tuber-like shape. They are not part of the tuber and potato family and have no other similarities beyond their shape.
Truffles are considered hypogean mushrooms, meaning they grow exclusively underground. They are ectomycorrhizal fungi, forming symbiotic relationships with the roots of trees. This relationship is mutualistic, as truffles provide valuable nutrients to the trees in exchange for carbohydrates. The unique aroma of truffles is thought to have evolved to entice animals to dig them up and spread their spores.
Mushrooms, on the other hand, typically produce spores that are easily dispersed by wind, rain, or animals. They are the above-ground fruit bodies of fungi, similar to how a flower is not the main body of a plant. Over time, mushroom caps began to enclose reproductive tissue, and the dispersal of spores shifted from wind and rain to primarily utilizing animals. This fundamental difference in structure and reproduction sets truffles apart from both mushrooms and tubers.

Truffles grow underground, mushrooms above ground
Mushrooms and truffles are both types of fungi. However, they have distinct growing patterns and reproductive mechanisms. Mushrooms grow above ground, whereas truffles grow underground.
Mushrooms grow from fungal spores that thrive in damp, dark conditions. They require a medium that is high in decaying plant matter. They often spring directly from dead trees. Mushrooms are grown in highly controlled environments, and they are harvested by hand throughout a 16-35 day cycle.
Truffles, on the other hand, are a type of fungus that grows underground, forming symbiotic relationships with the roots of certain trees. Truffles are notoriously difficult to cultivate, and they are not considered mushrooms because they do not develop an above-ground fruiting body with a visible stem and cap. Instead, truffles reproduce by distributing spores that are generally dispersed through being eaten by animals and then excreted, rather than being released into the air like mushroom spores.
The unique smell and flavour of truffles are thought to entice digging animals like boars to dig up the fruiting bodies and spread their spores. This is why truffles are often foraged with the help of animals like pigs, which are attracted to the scent of truffles because they contain the pheromone androstenol, a sex hormone also found in the saliva of male pigs. Dogs are also used to locate truffles, as they are happy to settle for an alternative treat.
The evolution of subterranean fruiting bodies, like truffles, has occurred numerous times within the Ascomycota, Basidiomycota, and Glomeromycota. Phylogenetic evidence suggests that most subterranean fruiting bodies, like truffles, evolved from above-ground mushrooms.

Truffles are harder to cultivate than mushrooms
Truffles and mushrooms are both types of fungi, but they are not the same. While mushrooms grow above ground in a variety of environments, truffles grow underground and form symbiotic relationships with the roots of certain trees. This fundamental difference in structure and reproductive mechanism is why truffles are not classified as mushrooms.
Truffles have long eluded cultivation techniques, and even today, they are notoriously difficult to cultivate. While it is theoretically possible to cultivate truffles, it is extremely challenging and expensive. The challenge in growing significant quantities of truffles is that you need to grow both the tree and the fungus and get them to cooperate with each other in a very specific symbiotic relationship. This relationship cannot be forced or rushed and can take years to develop. Even if this condition is met, most mushrooms require specific environmental conditions in order to fruit, so you need to have the right climate, altitude, seasonal amounts of moisture, etc.
Truffles also have a very short shelf life, which makes things even harder. In addition, there are so many constituent parts to creating a truffle that it is very difficult to replicate these conditions from one location to another. From the terroir (soil), soil drainage, climate, amount of rain, and altitude to the symbiotic relationship between the truffle and the tree, proper inoculation of the tree, and the amount of time it takes for the tree's root system to start cultivating truffles—all of these factors make truffle cultivation very difficult to replicate in a lab.
While mushrooms can be easily preserved, whether whole in olive oil or blended into sauces, truffles are quite the opposite. The cooking process destroys the truffle's characteristic flavor and aroma, which is why they are shaved fresh over dishes like pasta, risotto, or egg preparations.

Truffles and mushrooms spread their spores differently
Truffles and mushrooms are both fungi, but they spread their spores differently. While mushrooms spread their spores through the air, truffles spread theirs through animals.
Mushrooms spread their spores through the air by creating their own airflow. They do this by utilising evaporation to induce a bit of airflow. Fungi are immobile, so they have evolved to spread their spores through the wind, or by shooting them out at high speeds in rapid succession. The spores are discharged from 0.5 to 1 mm from basidia, and the spacing between the gills of a mushroom determines its discharge range.
Truffles, on the other hand, spread their spores through animals. Truffles have a unique smell that attracts animals to dig them up and eat them. The spores are then spread to new places through the faeces of these animals. This is known as a sophisticated strategy of olfactory manipulation, similar to flowers that rely on insects and birds as dispersers and pollinators.
The different methods of spore dispersal in truffles and mushrooms are due to their evolutionary histories. Phylogenetic evidence suggests that most subterranean fruiting bodies, like truffles, evolved from above-ground mushrooms. Over time, the mushroom's stipes and caps were reduced, and the caps began to enclose reproductive tissue. This shift resulted in the dispersal of sexual spores through animals rather than wind and rain.
The distinction between truffles and mushrooms is important, as it highlights the diverse strategies employed by fungi to ensure the survival and propagation of their species. Truffles and mushrooms have adapted to their respective environments, with truffles forming symbiotic relationships with the roots of certain trees and mushrooms developing above-ground fruiting bodies.
