The Fascinating Map of Fungi

Things we can learn from the video

0:00Mushrooms are only part of a fungus; branching mycelium forms a much larger network.
1:27Fungi digest food externally, and some species trap nematode worms.
7:09Mycorrhizal partnerships let fungi and plant roots exchange nutrients.
11:15Fungal medicines include immunosuppressants, statins and penicillin.
18:01Fungal reproduction involves varied mating systems and spores that can help clouds form.
20:09Water moulds and slime moulds lack chitin cell walls and are not true fungi.

Mushrooms are only the visible beginning. In "The Fascinating Map of Fungi", Dominic Walliman follows the branching threads beneath them into tree-root partnerships, medicine, fermentation and the surprisingly complicated business of fungal reproduction.

The guide is now just short of a million views, more than a year after publication, and is the busiest of Domain of Science's older uploads right now. Walliman explains how fungi digest food outside their bodies and how some trap tiny nematode worms. Later, he separates true fungi from water moulds and slime moulds: sharing a name doesn't mean sharing a branch on the tree of life. The explainer ends with a sponsored segment for Brilliant.

There were no new uploads this week, and the subscriber count stayed unchanged. Daily viewing is a little below its usual level. Among neighbouring science channels, BBC Earth Science has a livelier picture, with daily views more than double its typical pace.

Domain of Science's other moving maps offer quite a change of scale. "The Complete Map of All 88 Constellations" charts the northern and southern skies and the people who defined their regions. "Will We EVER Complete Physics?" turns Walliman's map-making habit back on itself: after drawing so much of physics, he asks whether the subject could ever be finished.
