Blusher vs panther cap: how to tell them apart
Quick answer
The blusher's white flesh slowly turns pinkish red over a few minutes where cut, bruised or eaten by insects, and the stem base often shows reddish stains; the panther cap's flesh stays white. The warts and base differ too: grayish to pinkish warts and a plain bulb on the blusher, pure white warts and a bulb with a neat rolled collar on the panther cap.
Toxic lookalike
The blusher and the panther cap are toxic.
The panther cap (Amanita pantherina) contains ibotenic acid and muscimol. For the closely related western panther amanita, the University of British Columbia's Mushrooms Up! guide records symptoms 30 to 180 minutes after eating, peaking at 2 to 5 hours: confusion, vomiting, delirium, seizures and lethargy or coma, with recovery usually 4 to 12 hours after the first symptoms. The blusher (Amanita rubescens) contains a toxin in its raw state that destroys red blood cells (a hemolytic toxin) and causes anemia, according to First Nature; the same source records that the toxin is destroyed by thorough heating.
If someone has eaten a wild mushroom and feels unwell, or may have eaten one of these, call poison control now: 1-800-222-1222 in the US. Do not wait for symptoms.

FAQ
Common questions
Is the blusher poisonous?
Raw, it contains a toxin that destroys red blood cells. European guides list it as edible only after thorough heating, and North American guides add that it is easily confused with the panther cap.
What toxins are in the panther cap?
Ibotenic acid and muscimol, the same compounds as the fly agaric. Symptoms include confusion, delirium, vomiting and deep sleep or coma.
Can you tell a blusher from a panther cap in a photo?
Not reliably. Cap colors overlap, and the reddening flesh only shows after cutting. Pure white warts and a rolled collar on the bulb point to the panther cap if they are visible.

This page states what field guides record. It is not advice to eat, taste or handle anything, and a photo cannot settle edibility. If someone has eaten a wild mushroom that may be toxic, call poison control (1-800-222-1222 in the US) right away, before symptoms start: the deadliest species act hours later.
