🍄📸🧪 I was cloning a wood ear mushroom that I foraged recently. One of my plates was contaminated, so I let it grow. Then I thought I should definitely photograph it against a lamp and share it here. Perfect for @contamclub.bsky.social The red/pink pigment is likely produced by Fusarium mold.
Agar plate with wood ear mushroom tissues. The red/pink pigment diffusing into the agar is likely metabolites produced by Fusarium mold.  Bacterial growth is also visible. Petri dish is photographed against a lamp.

When an apple goes this bad, there’s only one thing to be done… … *takes photos*
A rotten apple retrieved from the bottom of a pack bought last week. It is a near-luminous red-tinged golden colour, speckled with spots of white mould up the right side that mass together to form a fuzzy covering on top.The same rotten apple seen from a different angle. The side facing the camera is sunken and oozing moisture down crumpled skin. Its reflection in the ceramic cooker top is sinister, so dark It appears black.

My contamination made it into the @contamclub.bsky.social calendar for 2026! 🦠 I just got my copy. Also will send out some calendars as x-mas presents to friends and collaborators. 🎅🏻🌲
Me dressed up for christmas , with a red x-mas hat and next to a lit x-mas tree. I am holding the contamination club calendar for 2026 with April turned up. It displays a mount Fuji like colony growth of a contaminant.
