In a Lilliputian world of leaf litter

Holmsley Inclosure, New Forest Each silk button spangle gall has a minute larva inside. Looked at later under the microscope, they remind us of a scrumptious doughnut

We drop down the side of this woodland on a bright day buffeted by a cold wind. First planted in 1811 with scots pine and oak, its fences now enclose a wide variety of trees. We turn along the eastern edge to find the lower gate and, on entering, are plunged into a claustrophobic tangle of branches, before quickly coming to a narrow path close set with brambles on one side and hollies on the other. The recent rains have made the soil beneath the fallen leaves a muddy squelch, deeply incised with fresh bike tracks.

Getting our eyes in, we begin to see a host of small brown and greyish fungi tucked into the patchwork of sodden foliage and decaying leaf-fall. For us, most of them are "little brown jobbies", as they are known to those without sufficient skill to identify them. We notice, too, some so much smaller that we are drawn into a Lilliputian world.
