What a rotter! – The Willow Shield

1 Comment/in , /by

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

Blue Hats for Winter – The Wood Blewit

11 Comments/in , , /by

This post was inspired by overhearing a conversation at my local pub where they raved on about a local guy who knew where the ‘Blue Legs’ were at! He had bags of them for sale! I naturally assumed they meant ‘Blewits’. Only later I have realised ‘Blue Legs’ are a common name given to ‘Field Blewits’ which are much less common than our Wood Blewits in question, which has the common name of ‘Blue Cap’. Often I have seen people get them mixed up, so this makes you appreciate the relevance of scientific ‘latin’ names. The scientific names make sense overall (even though they tend to change and move around as scientific understanding evolves).

Winter was making itself felt as it’s cold arm stretched across the land. But one lazy Sunday afternoon at the end of November, I dragged myself over to the local mushroom hangouts. Being south side of a major city you’re a little stuck for local woodland. Blaby on the other hand (South Leicester) comes up with the goods. We have a collection of mini public woodland and country byways. They’re all great because at one point or another they eventually end up at the local pub! Or is that my doing?

Anyway. For a casual stroll, I was surprised to come across quite a few lovely specimens. Three of them I’m still not sure about and still checking. But today I came across a solitary ‘Wood Blewit’ (Clitocybe/Lepista nuda). You’ll maybe notice I have filed this post both under ‘Identity Crisis’ AND ‘Woodland Treats’ categories. All the identification characteristics were there: The colour, the presence of a wavy margin and also it being a stand alone species, living on dead organic matter (saprotrophs). When picking them you’ll notice the the woodland floor wants to come with them too! Another tell tale ID sign. As looks can be deceiving, be aware of mistaking it for one of the ‘Webcaps’. A spore print (see how here) can help solve this issue.

See the pics below. I know they’re not of the best quality as I was bloody cold and didn’t have time to get the best results!

The blue (purple/violet) colours of the Wood Blewit mushroom

In fact, the first time I had taken a spore print of the Blewit, I was very unconvinced about the pale pink (or pale lilac) colour that was to be expected. It seemed to look like a very light brown!

But after some extra professional advice I was comforted in the fact that this was an understandable concern and that Webcaps have a very distinct ‘rust brown colour’ – which is good to know…
