What a rotter! – The Willow Shield

This is the first in my posts aimed at the Pluteus genera of mushrooms. Nearly always found on rotting wood including logs, stumps and general wood debris, hence the savvy title. The common name used for this group is ”Shield”, and a very apt name it is too because they always remind me of actual shields – fancy that!

Pluteus salicinusFeatured this time is the Willow Shield (Pluteus salicinous). I almost missed several of these on a walk through the woods. The upper canopy had drained quite a lot of the natural light. It was also still dry out there as the recent weather hadn’t delivered much rain – but plenty of sticky warm days!

Perhaps the warmth and dryness had taken the moisture out of these beauties, the wrinkled edges in the photos aren’t usually a common feature of a healthy young specimen.

Imperfections aside, the Willow Shield is a pretty dull mushroom anyway – but on closer inspection really quite distinct. The first thing that struck me was the colour of the cap. Although it appears a mundane grey in these photos (better captured in image below) there is an overall tint of blue (sometimes green) but very subtle, and that really caught my attention. It’s sometimes hard to capture in a photograph, but part of that may be a trick of light and what angle you view it from – or do I need another camera!?

The cap holds further details for inspection. It is noticeably darker at the centre, and after flattening out as it matures it usually leaves a slight umbo (or bump). This central point is very finely velvety to the touch where subtle coloured streaks radiate outwards from it’s centre. The stem itself is a good old ‘uncomplicated’ smooth white (although sometimes with a darker tinge at it’s base).

As with all Pluteus mushrooms, their gills are free from the stem and the spore print will be pink. As this mushroom ages, it’s gills will turn from white to pink as the spores mature.

And last but not least you’ve probably noticed I have categorised this post in ‘What’s your Poison?’ and ‘Tales of Toadstools / The Inedibles!’ because this mushroom is generally classed as inedible. But I have read elsewhere that unlike other Pluteus species, this mushroom (or now should I say toadstool!?) contains small amounts of psilocybin (compound psilocin). This is the same substance found in Magic Mushrooms (or Liberty Caps). So it’s advisable to leave this toadstool alone.

Notice the cap has a slight blue colouring and a distinctive bump (or umbo) at the centre which is darker in colour

November Rain brings the Field and Horse Mushrooms

Well, there’s been some heavy weather this month. Not so good for some of the country with dire floods and really dangerous conditions. In my home town, Blaby, Leicester it’s been heavy rain and wind but fortunately with no unfortunate consequences.

Only a few days ago though, this rain has promoted the popping up of many, and I mean many Field and Horse Mushrooms.

I actually didn’t go out mushroom hunting for these (hence the weather being too blustery). They were in a field right next door to my father-in-law’s house. So, while out walking the dogs he harvested the goods. Half of which he gave to me.

Somewhat unnerving though was his attitude to mushroom picking on the off chance. “They looked OK, They’re alright, we’ll eat them tonight!”. Now I’m sure he probably knows from experience which ones ‘look’ OK, but I had to check. Fortunately they were brilliantly large and tasty Horse mushrooms (Agaricus arvensis) and Field mushrooms (Argaricus campestris). Very nice. But I hope he doesn’t go to the woods grabbing everything he sees for his pot. I’m sure he won’t…

Here’s a picture of some of the Field Mushrooms, stems removed, ready for the pan.

Wild mushroom hunting. Edible Agaricus mushrooms. Young(ish( Field Mushrooms.

The Genus AGARICUS (Wood Mushrooms/Mushrooms): Characteristics to look out for:

• Many discolour yellowish, reddish or pinkish when cut or bruised.
• Those that discolour bright/chrome yellow should be avoided for consumption.
• Gills in young specimens are often pink (white in a few) – maturing darker brown.
• Make note of any smells, such as aniseed or a typical strong ‘supermarket’ mushroom smell.
