Nectria cinnabarina – a tiny fungus on wood

Nectria cinnabarina in garden

Storm Doris is blowing a gale today, but in between the showers and racing ragged clouds was a fine half-hour of warm sunshine, the daffodils glowing yellow. A cut twig caught my eye in the brilliant light, speckled with tiny spheres, the pinkish fruiting bodies of the Ascomycete Nectria cinnabarina, a small saprophytic fungus, also called Coral Spot.

Nature Red in Tooth and Claw

Pigeon killed and partly eaten by a Sparrowhawk

Many of the photos on this website show nature at its prettiest. Well, not today, but still surely of interest. Nature is in Alfred, Lord Tennyson’s phrase “red in tooth and claw”—or in this case in beak and claw: a Wood Pigeon killed, plucked and partly eaten by a Sparrowhawk. There were many plucked feathers all about, mainly to the right and bottom of the image, an instantly recognisable scene of predation and carnage. The Sparrowhawks nest at the other end of the reserve, and they kill a pigeon somewhere that we notice most weeks. Netty disturbed this one on her walk round this morning, and given the cold damp weather she was surely the first person into the reserve today. The sparrowhawk, definitely not very large and brownish, was either a male or a juvenile.

A touch of winter at Wraysbury

Winter showed her wizened hand today. The bright sunshine of the morning quickly gave way to cloud under a chilly northerly wind. Zipping up my coat, I wondered if I’d see anything worth remarking, and plodded up the path in the flat light. I looked left at the river Colne, and a plump Water Vole splash-dived among some juicy Iris leaves that I guess it had been cutting. Once a common enough sighting, it’s now something very special.

The main lake was almost devoid of birds, a distant swan, a few black-headed gulls and a coot or two more or less summing it up, a dull day (apart from the vole). I rounded a bend and came face to face with a very fresh-faced, brightly-coloured fox. It stared at me for a glorious second, then turned tail and fled. Given the long narrow neck of land between the river and the lake, it must have run quite a way to escape.

Not much further, a riverside willow had fallen on to an ancient hawthorn, forming a striking arch. The broken trunk was quite hollow, only a couple of inches of the newest wood remaining as a thin fragile tube. These large trees grow rapidly to a considerable size — and suddenly fall. The wood is soft, and it seems that saprophytic fungi (or perhaps parasitic) can speedily destroy it. This tree was layered with a dry papery sheet of whitish mycelium, presumably whatever species it was that rotted the trunk hollow.

A dark brown Buzzard, almost without markings, floated broad-winged just above the small lakeside trees, almost close enough to touch.

Beside me, the lake suddenly exploded into a mass of pattering feet on water, as a dozen Gadwall rushed to take off. Perhaps these newly-arrived birds are from the frozen north, unused to the slightest human disturbance.

The end of the lake held a score of Tufted Duck, their numbers too increasing rapidly now, again presumably from colder lands to the north or east.

At the steel bridge, a Bullfinch repeated its insistent call, Deu, Deu. And over the grassy meadow, a Kestrel floated silently, hovered, drifted effortlessly upwind to hover again.

The Blusher, Amanita rubescens – an edible member of a dangerous genus. Its pink ‘blush’ when damaged can be seen in small patches of the cap and on the broken stalk.

Apart from the fungi named in the image captions, we also saw plenty of the Deceiver (Laccaria laccata); Amethyst Deceiver (Laccaria amethystina); assorted species of Fairy Bonnets (Mycena spp.); the Brown Rollrim (Paxillus involutus); Puffballs (Lycoperdon perlatum); and more. There was hardly any Birch Polypore – we often have fine big white brackets of them: just one small nodule, Piptoporus betulinus.
