A no brainer.

The Yellow Brain Fungus also has several common names including Golden Jelly fungus, Yellow Trembler, and Witches' Butter. This today was a lifer for me, and  have to say it is an incredibly coloured fungi which really stood out on the Oak branch. It is most frequently found on dead wood but attached and on recently fallen branches. The gelatinous, orange-yellow fruit body of the fungus, which can grow up to 3 inches in diameter, has a convoluted or lobed surface that is greasy or slimy when damp. It grows in crevices in bark, appearing during rainy weather. 

Within a few days after the rain it dries into a thin film or shrivelled mass capable of reviving after subsequent rain. This fungus occurs widely in deciduous and mixed forests and is widely distributed in temperate and tropical regions that include Africa, Asia, Australia, Europe, North and South America. Although considered bland and flavourless, the fungus is edible and produces carbohydrates that are attracting research interest because of their various biological activities.

The fruit body has an irregular shape, and usually breaks through the bark of dead branches. It is up to 3 inches broad and 1-2 inches high, rounded to variously lobed or brain-like in appearance. The fruit body is gelatin-like and appears tough when wet and hard when dry. The surface is usually smooth, the lobes translucent, deep yellow or bright yellow-orange, fading to pale yellow. 

Although some have claimed the fungus to be inedible or merely non-poisonous, most sources agree that it is edible but flavourless. Personally, I just like to admire fungi growing in their natural surroundings. The books state this to be a common fungi found in the winter time, but I have to admit it was certainly one that has eluded me until today. 

Funnily enough, when at an inland site I also visit, I came across a second specimen, although this afternoons find was only about twice the size of a 2p piece. So, two lifers in one day...  Fungi always fascinate me and this was another great one to add to my life list.
