A pair of nature lovers stumbled upon a foul-smelling alien-like growth while walking in woodland.

Sussex Wildlife Trust members Lisa Saw and Sue Robinson snapped the spooky specimen, which looks like an egg with protruding red tentacles, in East Sussex.

The rare, non-native species, which could be mistaken for an extra-terrestrial creature from a sci-fi film, travelled over from Australia at the beginning of the 20th century.

Devil’s fingers fungus starts its life in an egg-like structure, commonly called a witch’s egg. Once it has hatched it resembles more of an octopus like creature before it collapses after a few days and rots into the woodland floor.

The fungus attracts insects with its rotting meat-like odour.

When the insects land on the inner surface of the fungus, its spores attach to their feet and the fungus is able to spread in this way.

Lisa told Sussex Wildlife Trust she was thrilled to see the fungus.

“Clathrus archeri erupts from an egg and is covered in spore-containing gleba – not to be confused with melted chocolate – which flies will help to spread.

“I was thrilled to discover this colourful fungus and see a few of the eggs in East Sussex, mid to late October.

I’m a newbie when it comes to fungi and have really enjoyed getting out this autumn photographing the different varieties – who knew there were so many. I also love the challenge of trying to identify them.”

“I love nothing more than being out in nature and, like so many people, it has been a lifeline during this challenging year,” she said.

“It’s been wonderful, and a privilege, to have been able to spend more time than usual appreciating what’s on my doorstep. I’m noticing so much more these days."
