Orca, sometimes known as ‘killer whales’, are unmistakable with their black and white markings. Although we do have a small group of orca who live in British waters, you would be lucky to see them!

The speckled wood prefers the dappled sunlight of woodland rides and edges, hedgerows and even gardens. Despite declines, its range has spread over recent years.

As its name suggests, the scarlet elfcup is a bright red, cup-shaped fungus. It is widespread, but scarce, and can be found on fallen twigs and branches, in shady, damp places.

The birch polypore only grows on Birch trees. This leathery bracket fungus has a rounded, coffee-coloured cap that was once used for sharpening tools, hence its other name: the 'Razorstrop fungus'.

The candlesnuff fungus is very common. It has an erect, stick-like or forked fruiting body with a black base and white, powdery tip. It grows on dead and rotting wood.

As its name suggests, the ruby elfcup is a bright red, cup-shaped fungus. It is widespread, but scarce, and can be found on fallen twigs and branches, particularly in areas with higher rainfall.

The turkeytail is a very colourful bracket fungus that grows throughout the year, but is at its best in the autumn. Its circular caps can be seen growing in tiers on trees and dead wood.

The White-clawed crayfish is a freshwater, bronze-coloured crustacean with pale undersides to its claws - hence the name. It is under threat from an invasive and introduced species of crayfish.
