Developing community resources: reference materials

Hi everyone! In an effort to help grow the community, and as someone new to mycology, I would like to gather recommendations for reference materials. My goal in this project is to develop this into a list for the community to share these resources. Books, websites, apps, anything is fair game for this list.

Please let me express my thanks in advance.

Edit: updating with recommendations.

Edit the second: going to build the list off of mobile and then share. Question? Do we include mycology-adjacent resources?

I'm thinking of the Crime pays but Botany Doesn't YouTube channel who occasionally covers mycology, as an example?
