In the foothills of Jirisan Mountain, Namwon, Jeollabuk-do, the Giant Puffball Mushroom (genus Calvatia), known as a globally rare species, has been discovered again this year. Appearing in the same region for an astonishing 13 consecutive years, the Giant Puffball Mushroom itself presents a natural wonder and highlights the value of the local ecological environment. The continuous appearance of this mysterious mushroom, which only emerges between summer and autumn when specific conditions are met, stimulates the curiosity of many.
Why the Giant Puffball Mushroom Has Bloomed for 13 Consecutive Years in Namwon
This July, the Giant Puffball Mushroom was discovered again at a black raspberry farm in Sannae-myeon, Namwon-si. This phenomenon has continued steadily for 13 years, starting in 2014. This farm, which was previously an apple orchard, has remained a habitat for the Giant Puffball Mushroom even after being converted into a black raspberry farm. Experts analyze that the continuous survival of the mushroom’s mycelia in the local soil, combined with appropriate climate and humidity conditions met each summer, leads to the formation of the mushrooms. In particular, the clean ecological environment in the foothills of Jirisan Mountain and environmentally friendly farming methods that minimize the use of pesticides and chemical fertilizers are credited with making this natural gift possible.
What are the Characteristics of the ‘Eyeball Candy’ Giant Puffball Mushroom?
The Giant Puffball Mushroom, as its name suggests, is characterized by its round, spherical shape and white color. ‘Daeng-gu-al’ (댕구알) refers to an old-fashioned candy called ‘nun-kkal-sa-tang’ (눈깔사탕), or ‘eyeball candy,’ and the mushroom’s name is derived from its appearance. This is a large mushroom, reaching diameters of 10-70 cm, with occasional super-large specimens found measuring up to 150 cm and weighing 20 kg. It primarily grows between summer and autumn in organic-rich bamboo forests, fields, grasslands, and mixed forests, and exhibits rapid growth within a few days after heavy monsoon rains.
The Efficacy and Misconceptions of the Giant Puffball Mushroom, Noted for its Rarity
The Giant Puffball Mushroom is known as a globally rare species and is sometimes traded at high prices online. In traditional folk medicine, the Giant Puffball Mushroom is believed to have various benefits.
- Traditional uses: Hemostasis, detoxification, relief of sore throat and pharyngitis
- Recent research: Discovery of substances that inhibit breast cancer cell growth
- Folk belief: Improvement of male sexual function
However, experts emphasize that these purported benefits have not been sufficiently scientifically proven, and due to its small population and lack of proper toxicity assessment, it is not recommended for general consumption. It can only be eaten when young, when its internal tissue is white and firm. When mature, it turns brown and emits a strong ammonia smell, making it inedible.
The continuous discovery of the Giant Puffball Mushroom reminds us how precious and full of amazing secrets the nature around us is. Rather than indiscriminate harvesting, efforts to preserve the natural environment so that this rare mushroom can continue to grow healthily will be more important.
