Morchella

life science Maturity 11-13 Next article →

Morchella is a genus of edible sac fungi that belong to the order Pezizales. These fungi are part of the Ascomycota division. They are most famous for their unique appearance and their value to gourmet cooks. People in French and Catalan cuisines prize them highly. Because they are difficult to cultivate on farms, harvesting them in the wild is a multimillion-dollar industry. This industry is active in the temperate Northern Hemisphere. You can find them in North America, Turkey, China, India, and Pakistan. They also grow in the Himalayas.

The most recognizable feature of a morel is its cap. The cap has a honeycomb appearance. This look comes from a network of ridges and pits that cover the surface. Morels come in many different colors. You might see them in white, grey, black, brown, or yellow. Their shapes can be quite varied depending on their habitat. One very important physical trait is the internal structure. When you slice a true morel lengthwise, the cap is always hollow.

Identifying morels correctly is vital because some look-alikes are dangerous. Many people call similar mushrooms "false morels." One major group of look-alikes is the genus Gyromitra. These often have a wrinkled or cerebral appearance. This means they look like a brain rather than a honeycomb. Gyromitra species are often reddish-brown or dark brown. Another group to watch for is the genus Verpa. Verpa species are highly poisonous. You can tell them apart by slicing them longitudinally. Verpa stems contain a cottony substance. Also, their caps attach to the stem only at the very top.

Other mushrooms can also cause confusion for foragers. Some species of stinkhorns, known as Phallaceae, have a similar cap shape. However, they have a distinctive foul odor. Even true morels require careful handling. They can be toxic if they are consumed raw or undercooked. Foragers must be absolutely sure of their identification before eating.

The history of naming morels is quite complex. This field of study is called taxonomy. Christiaan Hendrik Persoon typified the genus in 1794. He used Morchella esculenta as the type species. Many scientists have studied these fungi over the years. Julius Vincenz von Krombholz and Émile Boudier published important works with detailed illustrations. Elias Fries described the important species Morchella elata and Morchella deliciosa in 1822. American mycologist Charles Peck described the large-spored Morchella angusticeps in 1887.

For a long time, scientists disagreed on how many species existed. This is because the fruit bodies are highly polymorphic. Polymorphic means they vary greatly in shape, color, and size. Some authors once suggested there were only three to six species. Other experts recognized as many as 34 species. Modern science uses molecular phylogenetics to solve these mysteries. This is the study of evolutionary relationships using DNA. Current data suggests there may be over seventy species worldwide. Many of these species show high continental endemism. This means they are often found only in specific geographic areas.

Recent years have brought many new discoveries. In 2012, researchers described many new taxa in Europe and North America. This caused some confusion with overlapping names, or synonyms. However, a transatlantic study by Richard and colleagues in 2014 helped resolve many issues. Since then, scientists have described new species in Australia, Canada, Cyprus, Israel, Spain, and Turkey. The genus is still undergoing extensive re-evaluation. We are constantly learning more about the complex family tree of these fascinating fungi.
