Birch polyphore or Razorstrop Fungus

This is Piptoporus betulinus found growing on a decaying birch stump on Chailey Common. They are multi-layered because the fruiting bodies persist from one year to the next with a new one forming each year. You can see the remains of the oldest ones rotting away in the top left photo. The original would have been much prettier; toasted on top and creamy white underneath. It is a very common fungus found on birch throughout the British Isles.
Interestingly bits of this fungus were found amongst the possessions of the 5500 year old mummy discovered in the Italian/Swiss Alps back in the 1990s. Otzi may have been carrying them to sharpen blades or possibly for its antibiotic properties.

Goat willow

Salix caprea is also known as the pussy willow because of its furry catkins or pussies.
Willows are dioecious and this one is a female with grey pussies.
It also provides equine services as a scratching post.
This was growing on Chailey Common and is quite a mature specimen. 

Grey willow (S. cinerea) is very similar but a key distinguishing feature is that if you peel the bark of a two-year old twig and run your fingernail around the wood you can feel ridges, whereas goat willow is smooth. 
I remember this by thinking of a smooth old goat. Why old goats might be so described is utterly irrelevant.

Scot's pine

 

 It was somewhat remiss of me to return from Scotland without a picture of the Scot's pine, but here's some growing on heath in Sussex. Chailey Common to be precise, a lovely stretch of greensand heath overlying the wealden clays. 

Pinus sylvestris is another of our three native conifers. (I've done one already so there's the customary big money prize for guessing the third. It grows locally on the steep south-facing slopes of the A27 road embankment just outside Brighton.)

It's very late so that's all today. Will flesh this out a bit more tomorrow.

Still very late so perhaps tomorrow...

Daffodil

What else could it be on St David's day? Narcissus pseudonarcissus or the daffodil. I'm not entirely sure which subspecies this is, but it could the the Tenby daffodil, N. pseudonarcissus ssp obvallaris.
They used to be in the lily family but are now in the  Amaryllidaceae. Most are garden escapes or have been planted, with the majority of native plants found in the west. 
I remember seeing the native ones for the first time when we met my parents in Newent and did the daffodil trail; it seemed unbelievable that such a stunning flower could have evolved in our climate.
Having just acquired a copy of Geoffrey Grigson's superlative work The Englishman's Flora I must include his quote from Gerard Manley Hopkins who, on espying some growing in Lancashire, wrote: "The bright yellow corolla is seeded with very fine spangles which give it a glister and lie on a ribbing which makes it like cloth of gold." Mr Grigson gives the derivation of the common name thus: 'through Mediaeval Latin affodilus and Latin asphodilus, to the Greek asphodelus, the name of the plant which grew across the meadows of the underworld and which belonged to Persephone, the Queen of Hell.'
These were growing on a bank surrounding the car park on Chailey Common on Friday. The ones in our garden are yet to break bud. Iechyd da everyone!
