Agreed.

North America was fundamentally changed in the last ice age to be dependent on fungi breaking down soil matter, as the native worms were frozen to extinction.

It’s interesting because we know enough about fungi to know it’s a fundamental aspect of the ecosystem, but continue to learn more as to its individual impact.

Because every species of fungi operates slightly differently, a homogenous model may not be ever be adequately functional due to the sheer number of species and regional differences alone.

Highly recommend people join mycological groups for more information. They are fun and often get scientists in their meetings to impart more knowledge to us plebiscites.
