Kowloon Walled City

A German documentary made in 1989 about Hong Kong's Walled City. An extraordinary section of piled on construction - dwelling upon dwelling with no sunlight penetrating the six squared kilometer and 12 storey elevated lot, home to 50,000 residents, who live an ordered and complexly tiered life in incredibly stressed physical conditions - but still, space is made

Found this mushroom the other day. 
It appears to be a bolete covered with the white powder

I read it is mycelium of a mycoparasitic fungus belonging to the genus Verticillium, a genus of conidial fungi. 

Same idea as the choice lobster mushroom, a fungi-on-fungi arrangement.

This one is not edible though....

As usual, my search yielded an overwhelming amount of new and amazing information about mushrooms. Including this ted-talk by Paul Stamets who, outlines the extraordinary range, form, and incredible story of critical sentient fungi and the six specific ways in which it could restore the health of the planet. 

It is a tidy talk but humans don't communicate like mushrooms so it's unlikely we'll carry out any of these six ways.

 
An article on BBC's website July 11 2015 about the "Wood Wide Web"   here. It details many examples of mycorrhizae; communication between plants via mycellia.

The article provides a link to a 5 min documentary on the work of Prof. Suzanne Simard, UBC Faculty of Forestry, who studies the underground communication network of trees; 

"Mycorrhizal fungi form obligate symbioses with trees, where the tree supplies the fungus with carbohydrate energy in return for water and nutrients the fungal mycelia gather from the soil". 

 There is a substantial text entry attached to the You Tube post which is a good read.
