Large as life – The Giant Puffball

8 Comments/in , /by

There is no danger in mistaking this fungus with any other. Nothing comes close to its unique size and appearance. Everyone should feel lucky if they ever find any of these beauties in their prime. I only have the occasional luck here and there. They’re either too young, too old or vandalized! Late summer and autumn is the best time to go hunting for them.

PuffballsThe pictures of these magnificent Giant Puffballs (Calvatia gigantea) were kindly supplied by Brian Friend (excluding the header & bottom right image) taken in his garden in Stickney, Lincolnshire. My discoveries to date haven’t been particularly photogenic, so many thanks again Brian.

So here were not just one, but several Giant Puffballs in a long line – or so it seems. They are actually part of a large partial ring. The averge puffball size I would say would be approximately 20-23cm in diametre (around 4kg). They could also still be in the process of growing even larger. Mature specimens can reach up to 80cm across (approx. 20kg) or even larger in some exceptional cases.

Apart from hedgerows and woodland edges, it is gardens and pasture land that are the most common habitat for this fungus, often found in full or partial fairy rings (as in this case).

The outer skin is white or creamy white and is firm and leathery to the touch. The inner flesh contains a dense white spore mass, known as gleba. These young reproductive spores amount in excess to around 7-8 trillion – and sometimes more. That’s one determined fungus keen on reproduction! However, only a couple of the spores may find purchase and reproduce elsewhere. Maybe this is not a bad thing, otherwise we’d be knee deep in them every autumn.

With age, the skin rots away and peels, leaving the now mature olive-brown spores to be released. This is further helped when the whole fruiting body becomes detached from it’s relatively small mycelial attachment (small white root-like appendage) and is free to roll ‘not-so-gracefully’ over the surrounding grassland.

If you’re lucky enough to find these magnificent white balls in their prime, the young white flesh is excellent for eating, and there’s a wealth of recipes out there for it. Here’s just a choice few:

Happy Hunting…

Golf balls in the grass? – Meadow Puffpall

4 Comments/in , , /by

My first visit to a field nearby my house in Blaby, Leicestershire on a mild august day was only slightly productive but good fun. I chose the slightly odd title of this post for one good reason – the land adjacent (separated by a patchy hedge) is one huge golf course and as I walked through the neighbouring field I heard the constant groans and cursing of the golfers searching for their missing balls! It was an odd coincidence to come across these white balls poking their heads up through the grass. No wonder they can’t find them!

But wait. I was happily mistaken. These little white balls of fun were Meadow Puffballs (Vascellum pratense). On further research I’ve discovered they are common on and around golf courses, so perhaps my story isn’t that unique after all. Other main habitats include lawns, pasture and of course meadows.

Meadow PuffballThere were around a dozen or so sprinkled around a 2-3 metre radius. Some were on their own and some were in groups of two or three. Unlike the Common Puffball (found mainly in open woodland) their stems are quite short, so they sit ‘squat’ like in the grass and they are not as large in width either, from 2-4cm across. The surface has uniformly patterned, delicate white specks. If you touch them with your finger, the powdery-like texture smudges off to create a smooth surface. On younger specimens you’ll also notice a light yellow tone about them.

These young puffballs (like most of the ‘white’ species) are edible and good. Especially nice if coated in a breadcrumb mix and deep fried. It has quite a mild flavour. If you find a Common Puffball you may have to peel the outer skin which is thicker than the Meadow Puffball. This can be a pain! But definitely worth a taste.

Avoid older specimens as they taste pretty rancid, but not poisonous in any way. Best rule is – ‘whiter the better’. Slice one in half and take a look inside. It should be a nice solid white. If there are any other colours going on in there, it’s best to forget it.

Have a look at the Meadow Puffballs in all their glory below. On the right is an example of an older specimen where, as you can see, turns light brown with the top broken open at maturity to release its spores. At the end of it’s days it still has the added usefulness as a pixies bath tub – or so I’ve been told!

P.S. Also see – The Common Puffball and the Spiny Puffball.

As mentioned above be wary not to mistake small white ball or ‘egg-shaped’ fungi. These could be other poisonous toadstools in early development. For example the Death Cap starts life in a small white egg sack. Slicing it in half will reveal the young mushroom shape inside though. And besides, it’s a good tip to bear in mind and keep you on your toes. Be safe out there kids!

The PUFFBALLS/EARTHBALLS & ALLIES (Stomach fungi): Characteristics to look out for:

• Main fruting body is ball shaped, irregular or pedicel shaped. Broken or split at maturity to release spores
• Interior of fruiting body full of gleba (spores); solid when young, as a powder at maturity.
• Often small or no visible stem.
