Sometimes mushrooms work hard to hide their key identification features from you. Sometimes, they say "Hello, I am an Amanita, for my stalk has burst through an egg-like sac which remains, torn, and in the keys you'll see it called the universal veil. You're welcome!"

A graceful light brown mushroom with its thin stalk rising from a forest floor of dead needles and leaves and green moss. The cap is flat, about 2" diameter, and near the edges mostly transparent so you can see the gills underneath like ribs. At the base, the stalk has clearly torn through a small capsule of fabric-like tissue which remains.

Reminder to the media reporting on European wildfires: please don't say that forest has been "destroyed" or "lost": As developers are waiting for a chance to use these areas for other purposes don't imply that they have become worthless. Say "affected" or some similar wording instead. f24.my/C3vq.BS

Bollen worden geteeld met veel gif. Daarna gespoeld. Dat bezinksel wordt op het land uitgereden, waar wederom op wordt geteeld met (nog meer) gif. En dat vormt volgens de politiek en RvS geen enkel gevaar. Gezondheid wederom ondergeschikt aan het belang (€) van één boer. www.bd.nl/sint-michiel...

I was guest lecturer in a course coordinated by Stefano Boeri for the Polytechnic University of Milan. Using urban evolution principles, the students argued for urban planning decisions from the perspective of several urban animals. Lovely to see how this worked out! www.euronews.com/2026/07/02/p...
