February mushroom – The Mushroom Diary – UK Wild Mushroom Hunting Blog

It may seem a little strange to feature this mushroom in February when it’s actually an autumn species. Well, mainly!  

But year after year I often come across the Tawny Funnel (Lepista flaccida) in January or early February, as in this case. At first I thought I had an unfamiliar species to identify – but I have read (and heard) from fellow foragers and field mycologists that this is not so uncommon.

After all, the Tawny Funnel is usually one of late fruiting autumn species. Maybe it has unfinished business -waits until milder times at the start of the year to carry on. Who knows?

When young, the cap is flattish and convex but soon develops its distinctive ‘funnel’ shape which causes some confusion, as you would think that you’re dealing with a true Funnel mushroom – i.e. a Clitocybe species. In fact this mushroom has been formally known C. flaccida and some mycologists have named it C.inversa, or consider it to be a different species entirely. One reason it has been moved to this genus is because of its warty spores and moveable gills, features the same as the other common Lepistas (or Blewits) such as the Wood Blewit and Field Blewit.

The real confusion starts when you compare it to the Common Funnel (Clitocybe gibba) which looks like its identical twin! However it is only situated in broad-leaved woods and heaths, whereas L.flaccida appears in both deciduous and coniferous woodland, especially nutrient rich soil.

I’ve been experimenting over the years to see if I can recognise any macro features while out in the field to distinguish between the two. I’m still not 100% sure if you can, and I think true ID will be from looking at the microscopic spores. However, not everyone has access to a microscope so I’ll go on to mention what to look out for. Here goes…

This mushroom is often found in clustered groups and full or partial fairy rings in the soil and leaf litter. Average cap sizes of mature specimens are around 5 to 9cm across.

There are many changes throughout its life cycle, so expect to see variable colour variations of this mushroom. The young flattened-convex cap is pale ochre and is strongly hygrophanous (unlike C.gibba) and you will see pale/darker areas depending on the moisture in the cap. Also look out for water marks around the edge of the cap. With age, it becomes darker orange-brown (shades vary) as the distinctive funnel becomes more apparent. There may also be several darker spotted areas scattered across the surface.

The whitish-yellow gills are crowded (more so than the Common Funnel) and heavily integrated with the stem (decurrent) which is paler in colour than the cap. It is often curved slightly towards the white woolly base.

Take a whiff!

Smell is also an important factor here, as the Common Funnel and Tawny Funnel differ. The Common Funnel has a faintish odour of almonds (also described as new-mown hay!) whereas the Tawny Funnel is more or less non descriptive, but there may be a faint spicy odour.

This mushroom is a great challenge, so good luck in identification and your spring forages in general. Enjoy.

Notice the varied shades from light ochre to tawny and the very crowded decurrent gills.

QUICK ID TABLE: TAWNY FUNNEL Lepista flaccida

CAP / FLESH

2-9cm across. Initially flattish to convex then funnel shaped. Pale ochre, darkening tawny brown with age. Often darker spots. Thin flesh, pale to tan.

STEM

3-5cm x 0.5-1cm. Paler than cap. Becomes hollow. White woolly base.

GILLS / SPORE PRINT

Very decurrent, narrow & crowded. Whitish to yellowish.
Spore Print: Creamy white (see how to take a spore print here).

HABITAT / SEASON

On soil and in leaf litter of coniferous & broadleaved woods. Autumn. Sometimes in January & February.

EDIBILITY

Edible, but flesh is too thin & has an unpleasant taste.

The Genus LEPISTA (Blewits): Characteristics to look out for:

• Small to medium size. Pale to brownish caps. Some feature lilac/purple colouring on cap and stem.
• Pale pink spore print (see how to take a spore print here).

This is another species I often find in urban locations as well out in woodland or the countryside, especially at this time of year in mild January or February months. The Tubaria species are often overlooked due to their small size and colour which helps them blend into their surroundings.

The Scurfy Twiglet (Tubaria furfuracea) is one of, if not, the most common of all the Tubaria (Twiglet) species. Typically small, reddish brown, found in scattered groups on twigs in and around wood debris. These particular ones were just in front of a hedgerow amongst the damp twigs and leaf litter. I was particularly proud in spotting them as I was riding by on my bicycle at the time! They can also appear on chippings and deciduous woodland floors.

The ‘Scurfy’ term relates to the fine flaky texture on the cap where velar remnants can be found on the surface. This often produces a dotted area around the margin (edge) of the younger cap, which is an attractive and useful identification feature.

When young, the cap is rounded or dome shaped, soon expanding with noticeable striated markings. The flesh is hygrophanous, meaning its colour changes depending on the levels of water absorbed by the mushroom. It can become pallid or creamy white as it dries and ages (see images below). Sometimes you may see the entire cap fade to cream, which makes it appear to be some other species. Very odd!

You may come across caps of older and/or larger specimens which drastically curl back on themselves, exposing their widely spaced gills outwards. Again, this is a typical feature often seen on the Scurfy Twiglet. Look closely at the gills – they have an adnate attachment (widely attached to the stem) but are also very slightly decurrent (running down the stem). The stem is coloured similar to the rest of the mushroom and is covered in fine white down at the base which tends to cling to the surrounding substrate.

Keep a look out for these guys, especially during the early months of the year. But as we’re well on the way to Spring now, there may not be many around now. Next year then!

Note: I posted an article on the Winter Twiglet (Tubaria hiemalis) in February 2011, and I still believe it is. They are practically identical and hard to distinguish between in the field. The gills were not slightly decurrent like the Scurfy Twiglet, neither did it have any velar remnants. Without going back to take a closer look, I can’t be 100% sure, but they are very much of a muchness and are visually almost identical.

Scurfy Twiglet (Tubaria furfuracea) Often late in the year, but also in February/March time.

QUICK ID TABLE: SCURFY TWIGLET Tubaria furfuracea
