About North American Mushroom Conference, ISMS and mushroom business in US. Everything in one publication


This post is also available in: English Russian Polish

26th North American Mushroom Conference and the 20th Congress International Society for Mushroom Science took place on 26-29th of February in JW Marriott hotel in Las Vegas, USA.

Two events (ISMS & NAMC) in one gathered more than 500 participants.

In 2024 – American mushroom market is growing. It feels good after banning of canned import of mushrooms from Europe (however some producers start complaining on Canadian mushrooms import). American industry is still characterised by Phase 2 domination, large amount of mushrooms are grown on wooden shelves, flies remain as one of the major problems, labour shortage hurts a lot, as a reason of lighter casing than in Europe number of farms tend to have lighter mushrooms. As well the competition between the farms is growing. The requirements for mushroom quality on the market go up. The margin is smaller and smaller.

In US they tend to have quantity focus more than quality, the yield can be up to 40 kg per m2 what is achieved mostly by putting more compost on the shelf. Another feature is a tendency to have very old growing rooms and very modern packing house.


In US we see developing of  very promising ideas of using mushroom mycelium for supplements, plant  bacon, leather, furniture, packaging etc.

Among the speakers were Dr. Shiuan Chen, Dr. Eoin O’Connor, Dr. Lynn Rothschild, Gavin McIntyre, Ecovative, John Pecchia, PennState, Helen Grogan, Teagasc, Michael Kertesz, University of Sydney, Dr. Ralph Noble, Jim Angelucci, Phillips Mushroom Farms, Phil Coles, Lehigh University, Ed Herr, Herr Foods Incorporated, Cathy Burns, International Fresh Produce Association, Anne-Marie Roerink, President, 201 Analytics, Lucinda Williams, Hazel Dell Mushrooms, Pete Gray, Phillips Mushrooms, Eric Rose, River Valley Ranch.

The most popular were the topics of harvesting automation, of peat alternatives, diseases control, sustainability, alternative mycelium usage and others.
