Kathmandu is the capital city of Nepal. It’s unclear who collected the first specimen. Some suggest it was one of several specimens collected by John Allen, but he only mentioned one Nepalese strain.
Wherever it came from, this is a great first strain for new growers because of how well-rounded it is. The Kathmandu mushroom strain doesn’t excel in any one category but offers a good balance of fast colonization, resistance to contamination, medium to large mushrooms size, and ease of germination and spore collection.
