Beware the Fool’s Funnel
Experienced foragers often say, if you want to familiarise yourself with only a few mushrooms, it’s always best to recognise the deadly ones! Wise words indeed.
The Fool’s Funnel (Clitocybe rivulosa aka C.dealbata) is one of the more common poisonous species to be found in the UK, as well as in Europe and North America. It appears, alarmingly enough, in some very ‘people orientated’ places such as lawns, parks, road sides etc; in sandy soil, during late summer to late autumn.
The toxic culprit here is muscarine (found in many other poisonous fungi), and with a good dose it can cause some very unpleasant symptoms, and in some cases – death. So it goes without saying, don’t be too hasty in picking these innocent looking mushrooms. Here’s what to look out for:
Although not that large (around 4-6cm when mature), they often grow in small to medium groups and sometimes partial or full rings in grass. One of the largest partial rings I found were right in the middle of a local park.
The cap is powdered white often with concentric rings or blotch marks which show the darker buff coloured flesh beneath (or even cracking, depending on condition). This is a good identification marker to note. The shape is initially rounded but it soon flattens out, usually developing the common ‘funnel shape’ and the margin remains slightly inrolled.
I stipulated on my mushroom identification page that there are no ‘golden rules’ or ‘one tip fits all’ in identifying different species, but if you want a good rule, then always be extremely wary of white gilled mushrooms. Several deadly species have white gills, but then again they can also have different coloured gills! So I guess what I’m trying to say is – ‘If you don’t know it, then don’t eat it‘ – simple. (I’m not sure if that was pointless and wasted paragraph! But there you go…)
In this case (typical for a funnel mushroom) the white/whitish-buff gills run decurrently down the stem (which share the same colour as the cap). They are quite crowded and turn more buff coloured as the fungi ages.
Last but not least; the flesh, if crushed between the fingers, will deliver a ‘sweetish’ smell, but I’d advise you wash or wipe your hands afterwards, and make sure you’re not tempted to a little nibble!
