These delicate fungi appear suddenly, when the temperature and humidity are just right.

Equally suddenly, when the humidity alters, they disappear just as unexpectedly, quickly collapsing and shriveling to nothing. They are truly evanescent features of the woodland, emerging from the dead wood on which they grow and feed.  This year, at the bottom of our garden, there was an unusually large colony of fungi on dead wood in such close proximity that I dubbed it the dead wood society, even though their mysterious community was fleeting.

As far as I can work out these fungi are one of the 150 or so species in the large and cosmopolitan Crepidotus genus.
