In a January melt in Ottawa there would be sleeves of ice on tree trunks and ice varnishing sidewalk edges. After a winter of rain in London, moss slicks the bottom of walls and walk edgings, and adheres to tree trunks in a bright green, almost fluorescent. Not the deep soft green of moss growing on the earth in a woods. This green is like algae, new and greedy.

The park offered a fungal tour. I didn’t go.
