A rare and striking yellow-coloured puffball mushroom has been documented in Longding district, highlighting the rich yet largely unexplored fungal biodiversity of Arunachal Pradesh.
The discovery was made on June 4, 2026, during a field visit to Zedua village by a team from ICAR–Krishi Vigyan Kendra (KVK), Longding. The mushroom was found growing naturally on decaying woody debris and organic-rich soil.
Based on its distinctive yellow globose fruiting body and puffball-like morphology, the specimen was tentatively identified as Bovista colorata, commonly known as the Yellow Puffball Mushroom, by Dr. Deep Narayan Mishra, Subject Matter Specialist (Plant Pathology), ICAR-KVK, Longding.
While detailed microscopic examination and molecular studies are required for definitive taxonomic confirmation, a preliminary review of available scientific literature indicates that documented records of this species from Longding district are currently lacking. If confirmed, the finding could represent one of the earliest documented field records of Bovista colorata from the district and a valuable addition to the known macrofungal diversity of Arunachal Pradesh.
Unlike conventional mushrooms that produce spores through gills beneath a cap, puffball fungi generate millions of microscopic spores within a closed, spherical fruiting body. As the mushroom matures, its internal tissue transforms into a fine powdery spore mass that is dispersed by wind, raindrops, or physical disturbance, enabling efficient long-distance spread.
Ecologically, species of Bovista play a vital role as decomposers. They contribute to the breakdown of lignocellulosic plant residues, nutrient recycling, carbon cycling, and the formation of soil organic matter, thereby supporting ecosystem health and soil fertility.
Several puffball species are also recognized for their nutritional value. Young fruiting bodies have been reported to contain proteins, dietary fibre, essential amino acids, minerals, and antioxidant compounds. Scientific studies have further identified bioactive metabolites with antimicrobial, antioxidant, anti-inflammatory, and potential pharmaceutical properties.
Historically, puffball spores have been used in certain traditional cultures as natural wound-dressing materials due to their moisture-absorbing and haemostatic characteristics. However, experts caution against consuming wild mushrooms without proper identification, as some immature poisonous species can closely resemble edible puffballs.
The observation underscores the immense but underexplored fungal wealth of the Eastern Himalayan region and highlights the need for systematic surveys, herbarium documentation, microscopic characterization, and DNA barcoding of wild macrofungi. Such research is essential for understanding their ecological significance and unlocking their agricultural, nutritional, medicinal, and biotechnological potential.
The field documentation was carried out with the active participation and support of other ICAR-KVK Longding scientists, including Shri Vikas, Subject Matter Specialist (Horticulture), and Dr. Amit Kumar, Subject Matter Specialist (Land and Water Management Engineering).
