Discover 3 Types of Morel Mushrooms

Morel mushrooms, scientifically known as Morchella, are a fascinating group of edible fungi. Mushroom enthusiasts and gourmet cooks alike highly regard these incredible mushrooms. Their exact classification and species count are subject to ongoing research and debate. However, in this article, we will explore some widely accepted classifications for types of morel mushrooms.

The number of recognized morel mushroom species worldwide, and specifically in North America, can vary depending on the source and the latest scientific discoveries. However, there are approximately over 80 to 100 described species of morel mushrooms globally. There are over 20 recognized species in North America.

Morels belong to the Morchellaceae family. This family is divided into clades or lineages based on genetic similarities and morphological characteristics. The exact number of clades can vary depending on the classification system used by researchers. Furthermore, researchers established three recognized clades or groups of morel mushrooms. They are referred to as the Rufobrunnea clade (white morels or M. section Rufobrunnea), the Esculenta clade (yellow morels or M. section Morchella), and the Elata clade (black morels or M. section Distantes).

Each clade contains several distinct species of morel mushrooms, with variations in size, shape, color, and habitat preferences. Once again, it’s important to note that ongoing research and taxonomic revisions may change the number of recognized species and their classification in the future.

The Three Types of Morel Mushrooms

As previously mentioned, researchers have classified morels into three types of morel mushrooms or clades. 

Rufobrunnea Clade (White Morels or M. Section Rufobrunnea)

The Rufobrunnea clade consists of white morels. Characteristics of these morel mushrooms include their white to pale yellow caps. The caps have a distinctive honeycomb-like texture formed by pits and ridges.

You can typically find this clade in grassy areas, meadows, and open woodlands. They are prevalent to spot in the spring. They require moist soil and a temperate climate for optimal growth. Notably, Rufobrunnea clade morels are saprobic, meaning they derive nourishment from dead or decaying organic matter. Consequently, their growth isn’t dependent on a particular tree species. Therefore, it occurs independently of trees.

You can primarily find the Rufobrunnea clade distributed across western North America, the Mediterranean Basin, and Australia. One of two species of this clade, Mochella anatolica, has only been found in the Mediterranean basin.

Esculenta Clade (Yellow Morels or M. Section Morchella)

The Esculenta clade comprises yellow morels. Characteristics of these morel mushrooms include their yellow to yellowish-brown caps. Like other morels, they have a honeycomb-like texture formed by pits and ridges. The honeycomb pattern of these morels is random and not vertical like Elata clade morels.

You can commonly find the Esculenta clade in woodlands, forests, and areas with deciduous trees in particular. Like with all morels, the exact timing of growth varies depending on the local climate and weather conditions. These morels are associated with the awakening of deciduous trees in the forest and depend on trees as their host.

You can find Esculenta clade morels in various parts of the world, including North America, Europe, and Asia. They are particularly common in regions of the United States and Canada.

Elata Clade (Black Morels or M. Section Distantes)

The Elata clade encompasses black morels. These morels have dark brown to blackish caps. Similar to other morels, they possess a honeycomb-like texture formed by pits and ridges. The cap tends to be longer than the stem, while the stem tends to be lighter than the cap. Moreover, the stem tends to be a sandy yellow or whitish color. 

Similar to Esculenta clade morels, you can typically find these morels in woodlands and forests, particularly in areas with coniferous trees. Like the other two clades, this clad is abundant during spring, thriving in moist soil and moderate climatic conditions.

Elata clade morels have a wide distribution, similar to the Esculenta clade morels. They inhabit various parts of the world, including North America, Europe, and Asia.

Finally, the coloration of all morels tends to indicate how strong the flavor is. Elata clade morels tend to be more nutty, earthy, and even smokey compared to the other two clades. This makes them a popular morel variety for various cuisines due to their distinct taste.

What Is the Difference Between the True Morel vs. the False Morel?

True morel mushrooms and false morel mushrooms are two distinct groups of fungi that differ in terms of their morphology, edibility, and potential toxicity. Understanding the differences between these two groups is crucial for foragers and mushroom enthusiasts to ensure their safety.

True Morel Mushrooms

People highly regard true morel mushrooms, which belong to the Morchella genus, for their distinctive appearance and culinary value. They include the three types of morel mushrooms, or clades, previously mentioned.

The characteristics of these morel mushrooms consist of cone-shaped or elongated fruiting bodies, which feature a cap with a wrinkled or pitted surface resembling a honeycomb. True morels have a hollow and interconnected interior within the cap. People prize these mushrooms for their rich flavor, making them popular in gourmet cuisine.

False Morel Mushrooms

False morel mushrooms, on the other hand, are from various genera, including primarily from the Gyromitra genus but also from the Verpa genus and even others. Unlike the true morels, false morels have caps that are irregularly convoluted or brain-like in shape, lacking the characteristic honeycomb structure. Instead of a hollow interior, false morels contain cotton-like or solid tissue.

Additionally, their caps are often fused to the stem at the top, while true morels have a free-hanging cap.

Toxicity

One critical difference between true and false morel mushrooms is their toxicity. False morels contain a compound called gyromitrin, which converts into a toxic chemical called monomethylhydrazine (MMH) during digestion.

MMH can cause severe poisoning symptoms, including nausea, vomiting, abdominal pain, dizziness, and in severe cases, liver damage. It is important to note that cooking false morels does not eliminate the toxin, and consumption is strongly discouraged.

Edibility

When correctly identified and prepared, true morel mushrooms are edible and safe for consumption. However, it is crucial to properly cook them before eating, as raw or undercooked morels can cause digestive discomfort for some individuals.

In contrast, false morel mushrooms are inedible or even toxic due to their potential toxicity and the difficulty in effectively removing the toxins through cooking. Consuming false morels can lead to severe health issues and shouldn’t be used in cooking.

Remember, it is essential to exercise caution and rely on reliable field guides or expert identification when foraging for mushrooms, especially distinguishing between true morels and false morels, to ensure your safety and enjoyment of these unique fungi.

Morel Mushroom Anatomy

Cap

The cap of a morel mushroom is the uppermost part of the fruiting body. It is typically cone-shaped or elongated, resembling a honeycomb. The surface of the cap is wrinkled or pitted. It forms a pattern of ridges and depressions that gives the mushroom its distinctive appearance. The cap color can vary among species, ranging from pale yellow to tan, brown, or even black.

Pits and Ridges

The pits and ridges on the surface of the morel cap are notable features. The pits, also known as alveoli or ascomata, are the depressions or indentations on the cap. They are arranged in a distinctive pattern, resembling a honeycomb or sponge-like structure. The ridges, also called conical fronds, are the elevated areas that separate the pits, giving the cap its textured appearance.

Hollow Stem

The stem of a morel mushroom is typically hollow, which means it contains empty space inside. The stem emerges from the base of the cap and extends downwards into the ground. It is usually light in color, ranging from whitish to pale yellow or tan. The stem supports the cap and connects it to the mycelium, the fungal network beneath the soil.

Fertile Surface

The fertile surface of a morel mushroom is located on the inner side of the cap, within the pits. It is composed of microscopic structures called asci, which contain the spores. Morel mushrooms are part of the Ascomycota phylum, characterized by the production of spores in sac-like structures known as asci.

Size

Morel mushrooms vary in size depending on the species and environmental conditions. They can range from a few centimeters to several inches in height. The cap size can also vary, with larger morels reaching several inches in length and smaller ones measuring just a few centimeters.
