Unconventional Fungi at Keston

Purple Jellydisc, Ascocoryne sarcoides. Keston Common, 15 October 2013

Of course, there are lots of fungi that are not at all like the conventional toadstools or mushrooms.  This one, that looks like miniature small intestines, grows on dead stumps and logs.

In fact, lots of fungi grow on dead wood.  Their mycelium is active inside the trunks, logs and branches, eating them away, and what we see is only a small part of the whole.  This Black Bulgar grows on fallen oak or beech.  In this case, it was on a beech trunk that had been felled as a precaution because it was infected by another fungus, the Giant Polypore, Meripilus giganteus, that causes a weakening white rot.  Such trees are felled by park managers so that they don't drop branches on passers-by.

But most  go for the dead wood.  This one is on a Silver Birch stump.  There are several species with this general appearance, small bracket fungi with a zoned appearance, but this one is particularly pretty; and not very common, apparently.

Pale Stagshorn,  Calocera pallidospathulata.  Keston Common,15 October 2013

This is another saprophyte, an eater of dead wood.  Those blunt spikes are about 1 1/2 cm tall.  There are several similar species, in varying sizes and shades of yellow.

Amanitas at Keston

Amanita fulva, Tawny Grisette.  Keston Common, 19 October 2013.

With names like Deathcap and Destroying Angel, Amanitas are not things you want to find on your plate.  They include the most poisonous and dangerous fungi in Britain.  They also include some of the prettiest.  And they also include Caesar's Mushroom, one of the tastiest edible mushrooms; the ones that the emperor Claudius loved.  It was, it is said, easy to add in some of the poisonous species that killed him. 

This one above, the Tawny Grisette, is also said to be edible.

Amanita rubescens var. annulosulphurea.  Keston Common,  19 October 2013.

This is a yellowish variety of a fungus called the Blusher, because of its reaction to damage.  It is said to be edible when cooked - but the water it is cooked in should be discarded.  In that respect it may be similar to this famous fungus:

Fly Agaric, Amanita muscaria.  Keston Common, 15 October 2013

- The Fly Agaric.  Some say that if this is boiled for a while and the water discarded, it becomes edible.  But that relies on several chancy factors and I would not recommend it.  My book says it should be treated as deadly poisonous; this is probably an exaggeration, but even so, I do not think it would be good for you.

Amanita phalloides, Death Cap.  Keston Common , 19 October 2013.

This one, even less so. This is definitely a killer, and this one specimen might be enough to do it.  The greenish cap, that disintegrating ring, and the bag-like volva at the base are the things to look for.   Even experienced mushroom foragers tend to leave well alone anything with a cap of that colour, just in case.

Lactarius species at Keston

Lactarius rufus, Rufous Milkcap.   Keston Common, 19 October 2013.

Fungus season!  I have been out with a couple of groups and I am learning quite a lot, which is easy from a starting point of not knowing very much at all.

The fungi in this post are Lactarius species.  It's easy to identify the genus, because when they are damaged, they exude "milk".  Of course, there are quite a few species, but most of them are identifiable with a bit of care - or so I am told!

This first one was growing in clumps among Scots Pine.  There are two possibilities for something among conifers that looks like this, and the other one has milk that turns green after a couple of minutes; which this didn't.

Lactarius vietus, Grey Milkcap.  Keston Common, 19 October 2013.

This one just has white milk.  It hides quite successfully in the leaf litter.  There's actually another species that is very similar, Lactarius turpis, and I.m not going to swear that this isn't it.

Some of them can be told by the taste of the milk.  It's not a good idea to taste fungi unless you are sure they are not deadly, and there are some deadly ones out there.  For these, I touched my finger to the milk and dabbed a tiny bit on my tongue.  Some are acrid, some are hot like a chilli.  The first one above has milk which tastes a little acrid, then suddenly becomes hot. 

Lactarius chrysorrheus, Yellowdrop Milkcap.  Keston Common, 19 October 2013.

The milk of this species is yellow from the start, and flows copiously. 

The common names shown here come from the Collins Complete Guide to British Mushrooms and Toadstools.  It's not really complete, but it is pretty good.  But the common names are mostly fanciful fabrications.  Some fungi do have real country names, but most don't.   The ones that sound either convincing or odd are probably genuine, like the Yellowdrop and this one:

Lactarius quietus, Oakbug Milkcap.   Keston Common, 19 October 2013.

It grows near oak trees. 

One of my fungus books, Mushrooms by Roger Phillips, gives brief notes as to edibility.  Of these four, the Oakbug Milkcap is noted as edible; the Yellowdrop is poisonous; L. vietus is listed as not edible, which probably means it doesn't taste good or is perhaps tough or fibrous; and L. rufus, although also not edible, is said to be used in some places as a seasoning after unspecified "special treatment".

Fungus foragers need to know their stuff.

Autumn Sunlight on Hayes Common

Sunlight through the trees on Hayes Common, 6 October 2013.

 When I go for a walk, there is usually a point at which I find I am smiling because my surroundings are so pleasant.  This morning it was here, in the woods of Hayes Common.

The leaves are just starting to change colour and some have fallen, but most are still on the trees.  The air is cool and refreshing, and the morning sun slants through the branches and silhouettes them.  Sunbeams light up irregular patches of ground.

And interesting root formations are highlighted.  These photos were taken with my iPhone 5s, and reduced in size but not cropped.  I did lighten the foregrounds very slightly in Photoshop.
