History has it that on this day in 1415 St.George’s Day was declared a national feast day. And if you’re lucky enough, you may find the perfect ingredient in the form of Calocybe gambosa, commonly known as St.George’s Mushroom.
This is one of the few edible species (of the larger kind) to be found in spring, and April 23rd was a convenient date to choose for its common name. They appear around this marked event, although in most cases they often arrive one or two weeks later, continuing to fruit until mid-June.
Their typical habitat is pastureland, but they also frequent grassy roadside verges and woodland edges, often in small to medium sized groups. At any other time of year (mainly the mushroom season in autumn) white gilled mushrooms (or ‘whitish’ as in C.gamboasa’s case) tend be untrusted, and for good reason too; many potently poisonous species share the same coloured gills. But during the spring season, there’s not too much the St.George’s Mushroom can be mistaken with.
Along with checking all the identification traits it’s also good (especially in this case) to check out the smell. The mature, fresh specimen will have a strong ‘mealy’ scent, which is an old fashioned term often used in describing certain mushrooms odours. It is hard to define but is often described either as fresh cucumber, watermelon rind, or an old grain mill. You’ll understand after a quick sniff!
Other features to note are the medium to large white dome like caps (becoming off-white with ochre hues) are sturdy and fleshy. They expand flatter with age, with an irregular wavy edge. The margin is always inrolled slightly. The gills (also off-white) are sinuate, narrow and densely crowded. The white stem is chunky and solid (with no ring present) and can be up to 4cm thick.
It goes without saying that the St.George’s Mushroom is a most welcome site for any forager, especially at this time of year. Highly prized, not only for its taste but also its flexibilty; it can be dried, pickled, cooked or even consumed raw. I don’t recommend eating it raw really, not because of digestive upset, but simply because it tastes (for want of a better word) ‘orrible! They’re best gently sautéd for quite a while due of their tough, fleshy nature.
I wish you luck in finding some this spring.
