Amarilla

Any suggestion what this might be? (I know its a mushroom). It was found on Hampstead Heath, London, UK.

Dryad's Saddle

Interesting, understated mushroom.

• Grows on trees.
• Has a porous underside much like a bolette.
• Usually found May to June.
• Younger specimens are better than older.

From a differential point of view, Dryad's saddle can be confused with other polypores, however its distinctive top, porous underside and "meatiness" (polypores have a woody texture) make it pretty distinctive.

The Foolproof Four

"The Foolproof Four" are four excellent species to begin with. Their characteristics are easily identified, and easy to remember. The Foolproof Four are: 

• Morels
• Chicken Mushroom
• Chanterelles
• Puffballs. 

I usually add Oysters and Hen of the Woods or a general bolete.

Get two good field guides, before you go out learn how to use them and read through them to familiarize yourself with their use.

What type of mushroom are these?
