Found on a bracket Fungus on an sessile oak tree, in mid september.
As an idea of scale, the balls are about 3mm diameter.

this pic gives an idea of size, the fungus is about 200mm across.

Baby Robin eggs?

Monkey spunk

Nah, robin eggs is blue, I think they're those little sugar Easter eggs; I always did wonder what layed them…

Wasp galls?

a bonus bit of fungus making a bid for freedom?

mmmm tasty 🙂 Beefsteak fungi. No idea about the little gauls though

I think peeps are right about the gall theory, i might try to find the tree again, then see if the balls are attached.

Research on the net, seems to show that it's not too common for the wasp to lay her eggs in a fungus. The galls them selves are a type of fungi if i've read it right.

Lots of beef steaks or ox tongue round here, never tried one, i hear the younger ones are a little more enjoyable.
