Yellow Brain FungusTremella mesenterica

This jelly fungus is most frequently found on dead but attached and on recently fallen branches. The gelatinous, orange-yellow fruit body of the fungus, which can grow up to 7.5 cm (3.0 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 rain it dries into a thin film or shriveled mass capable of reviving after subsequent rain. This fungus occurs widely in broadleaf 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 flavorless, the fungus is edible. Tremella mesenterica produces carbohydrates that are attracting research interest because of their various biological activities.

The species was originally described from Sweden as Helvella mesenterica by the naturalist Anders Jahan Retzius in 1769. Its distinctive appearance has led the species to accumulate a variety of common names, including "yellow trembler", "yellow brain", "golden jelly fungus", and "witches' butter", although this latter name is also applied to Exidia glandulosa. The species epithet is a Latin adjective formed from the Ancient Greek word μεσεντεριον (mesenterion), "middle intestine", from μεσο- (meso-, "middle, center") and εντερον (enteron, "intestine"), referring to its shape. (Extract from Wikipedia)

The Swedish name is ‘Gullkrös’.

Bonjour Ulla,
Trčs belle publication dans laquelle tu as merveilleusement restitué, sous une lumičre bien maitrisée, l'aspect translucide du sujet.
A bientôt sur TN pour de nouvelles aventures.

Hi Ulla,
Beautiful shot of (again) a species which is difficult to photograph. Wonderful sharpness, but I feel the red tone on the pic is a bit too strong. Tried to make a WS, I hope you like it. Ortherwise everything else is perfect on the photo, the crop I used is just a different idea. Informative note as always from you. Tfs Madame.
Friendly regards, László

Hello Ulla, very beautiful and artistic image of this interesting shaped fungus with nice details and composition.
TFS and regards,

Hola Ulla

Preciosa composición y original a su vez de esta especie de hongo tan extrańo, una composición excelente, contrastes y fondo adecuado.

PD. Gracias por la información que me dais para poder descifrar las especies.

Un saludo de Antonio

The look of this fungus is quite attractive, Ulla, and the "brain" part of its name is quite apt. You have done a great job in the existing light conditions, obtaining the most authentic and natural jelly-like appearance of the subject.
Thanks and best regards.

Dear Ulla!

Your picture and your notes are a very valuable scientific contribution and I have read your notes with great interest. This fungus is quite particular and its gelatinous aspect is well represented in your picture. Although it doesn't really look appetising I wonder what its taste would be...

Kind regards


Ciao Ulla, lovely composition with strange fungi, fantastic warm colors, splendid light and excellent sharpness, very well done my friend, ciao Silvio

Hallo Ulla
A great image of a very fascinating fungus. The ‘Gullkrös’ has a lovely texture that almost have 'wet' appearance. Great detail, beautiful complimentary background, colour and just the right amount of depth of field. I personally think that you have captured a special specimen here, as we are so used to the typical 'mushroom' shaped fungus. To me it looks like chewed bubblegum. Thanks for sharing. Best regards.

Hello Ulla,
your fungus capture really look slimy and shiny. Very nicely shown in exciting rich colours.
The composition of having the well textured branch makes it exciting.


Hello Ulla, very beautiful and strange imagine of fungi , details, light and sharpness perfect, interesting subject. A nice picture. Regards, Paolo

Hi Ulla,
You have uploaded a series of wonderful capture of the fungus and this one has unique colors and shapes. The name reflects the character really well and the silenced autumn colors is pleasing in the background. Interesting species and I have yet to see one around here. Well done and best regards.
