Spring fruitings of the Death Cap

Of the 230 observations of Amanita phalloides from CA on M.O.,
very few come from the March-May period.

There is a more expected trend of late summer/early fall outliers (late July through September) leading up to the ‘normal’ October-December season (peaking Nov/December). Even in January fruitings of this species seem uncommon, and interestingly/amazingly, there are NO observations of this species from February in CA on M.O. yet (!).

Here’s a graph showing the data:

Aside from this year and a couple one-offs, 2007 seemed to be a big year for A. phalloides spring fruiting, with four observations.

A list of the March-May fruitings followed by the year for quick reference appears below:
