Know what?

You are begging again them to be supervised.
How many dried things do you have ready?
When enough send me them critters.

I never saw any, just thought “Exidia glandulosa forms dark sepia to blackish, rubbery-gelatinous fruit bodies that are top-shaped (like an inverted cone) and around 3 cm (1.2 in) across. They are firm when fresh, but become lax and distorted with age or in wet weather. The fruit bodies occur singly or in small clusters. The upper, spore-bearing surface is shiny and dotted with small pimples or pegs. The undersurface is smooth and matte at first, but develops a dense covering of small, gelatinous spines. The fruit bodies are attached to the wood at the base. The spore print is white.8 When the fruit bodies are dried they can shrink to form a flattened black crust.” reproduces exactly what I saw in these.

I brought the twigs home, and all of them dried like black crust.

No.

The shape doesn’t fit for the most common of all Exidia. E. glandulosa/plana you can find on all kinds of hosts, it’s omnivorous, well, circum-growing or however you want to call that ;)
E. glandulosa is brainlike except when very young it can be top-like but never so definite as shown here in my experience. I still tend to recisa or truncata. The first pics (the black ones) look like truncata, the last pics (the brown ones) like recisa.

I think it is E. glandulosa, and this can have a oak host, so it matches perfectly.

Like whipping tops you mean ;)

Not sure about the spectrum of hosts in the Mediterraneans. Usually there is a big spectrum unless like in Middle Europe.

I thought the same :)

I use to see E.truncata, and it’s always ear like. These were… how can I call it… a sectioned cone shaped (like cup fungi), and attached lateraly. One side not smooth but not as in E. truncata, the upper side smooth except for the lighter coloured that has different shape and texture(what do you think this could be recisa/truncata?)

A big diversity of trees there, but no willows. Mainly, oaks, pines and cedars, birch and beeches, eucalyptus, etc. but yhe twigs were on the ground, and could be taken from another place, however they were under oaks.

it does look more like Exidia recisa to me.
Was it on willow?

Two species of exidia?

I don’t know if even there is a E. truncata here. The darker fruiting bodies are semi cone shaped, the lighter colored has different shape, texture and is on a different wood.
