Shelf fungus and Planthopper nymph

This is one of the sweetest things, so far !
There were three small shelf fungi ( about 10 mm wide) emerging from a log and in one of them was sheltering a small (4 mm long) cixiid plant hopper nymph (pic1). In the third shelf fungus was the exuvia, from which the little nymph had emerged (pic 2). Pic 3 shows the nymph out of the shelter.
The grey coloured nymph can be seen in some detail in pics 4 & 5. It appeared to have a narrow rostrum, wing buds and a short dorso-laterally flattened segmented abdomen. The rear end showed two white tufts on each side. Antennae - ? aristate.
