Common in a crowd – The Sulphur Tuft toadstool

There’s a extremely good chance of you finding a large group of Sulphur Tuft (Hypholoma fasiculare) at just about anytime of the year (especially from April to December). These beauties are extremely common in the UK and populate all types of woods and forests.

Sulphur Tuft Toadstool/MushroomThey are Saprotrophs (feeding off decaying matter) and appear in small tufts or large groups on dead/rotting wood (deciduous or coniferous), tree stumps or underground buried decaying wood or roots. The Hypholoma group of fungi like these are commonly known as ‘Brownie’.

When found in great numbers they are indeed a great sight to behold. When in their prime, the convex cap has an amazing bright sulphur-yellow colour with darker orange tones towards the centre. Remnants of the pale yellow veil (initially covering the gills) can be found at the edge (margin). The stem, which is often curved, share a similar yellow-brown colour (sometimes greenish) though dirty brown towards the base with a fibrous appearance. The gills , when younger, appear green-yellow which act as a good indicator in identification.

They almost look good enough to eat (and do have that ‘mushroomy’ smell), but unfortunately are not edible and will most likely give you stomach ache, vomiting and similar gastrointestinal symptoms. But the almost identical Conifer Tuft (Hypholoma capnodes) on the other hand – is edible – but less common throughout the year. As the name suggests, this species only grows in coniferous woods, in fact only always found on rotting tree stumps.

There is a ‘taste test’ you can make to identify between the two. Simply taste a small sample from the cap, making sure you don’t swallow! If it is bitter in taste, it is a Sulphur Tuft but if it is mild, then it is a Conifer Tuft.

Please note that you shouldn’t try this taste test with other mushrooms or toadstools you find (unless you know exactly what you’re dealing with. ie. Russula or Lactarius) as nasty results can come from tasting unknown species!

And if you do find some Conifer Tuft, I’ve heard they’re best steamed or used in a soup. I have no idea what they taste like!

Halloween Special 2 – Dead Man’s Fingers

It’s Halloween today, so to make this post especially spooky I’ve had to put this freaky fungus in. And what a fantastic name it has too.

Dead Man’s Fingers (Xylaria polymorpha) grows on dead wood (usually beech & sycamore) throughout the year, and is very common. The fruiting body is black and irregularly club shaped, often in small groups. It’s of a small(ish) size, reaching up to 8cm in height and up to 3cm in diametre. It’s hard outer shell protects the white flesh within where the spores are produced.

As you can guess this fungus is quite inedible and I don’t think anyone would fancy a nibble anyway! But the best thing about it is it’s strange general appearance. As you can see in the picture below there’s a small group of them growing on dead wood. If you look at the two on the far left, you can see where they get their common name from. Spooky!
