Week 1 Briefing: Credentials
The opening Briefing — what has to be true before anything under the soil counts as "a network," and the ground rules for keeping this course's central metaphor honest.

- Credentials — what it takes to be recognised as a network at all
- Phenomenon
- Mycorrhizal symbiosis basics: hyphae, the arbuscular/ectomycorrhizal split, and what counts as evidence of connection rather than mere proximity
Before the session#
Read the assigned primer on mycorrhizal structure. Bring one claim about “the wood wide web” you have picked up outside class — a documentary, a headline, a conversation. You are not defending it. You are putting it on the table.
In the session#
We build the credentials test together: for a plant-fungus pairing to earn the word “network” in this course, what has to be shown? Movement of carbon or nutrients, not just fungal presence. More than one host connected through a shared fungal individual, not just the same species growing nearby. Every later week’s diplomatic label has to clear this bar before it is allowed to sit on top of a real phenomenon.
Afterwards#
The test agreed here is the standing check for the rest of semester. Refer back to it before accepting any week’s metaphor at face value — including the convenor’s.
The spec
What you bring to the session. Written so a reader can tell whether it has been met without asking you.
- you can state, from memory, the difference between an arbuscular and an ectomycorrhizal association
- you can name one claim about fungal networks you have heard outside this course, and say what evidence would move you to believe or doubt it
- your development environment runs the course's toolchain and you can preview the site locally
