Autumn Wonders Or Autumn Disaster?

There have been several canine fatalities and incidents in the UK this autumn.

The common names of mushrooms that shouldn’t be eaten by humans provide clues as to the likely consequences and include the deadly webcap (Cortinarius rubellus), death cap (Amanita phalloides), destroying angel (Amanita virosa), funeral bell (Galerina marginata), fool’s funnel (Clitocybe rivulosa), panther cap (Amanita pantherina) and angel’s wings (Pleurocybella porrigens)

However, a wider range of mushrooms can be fatal to dogs.

The Clitocybe family of mushrooms are among the most likely to cause toxic symptoms because of the presence of muscarine.
