Sticky Suillus – Slippery Jack

It’s always good to venture further afield when hunting for new mushrooms, especially when you get a break or are on a holiday. I had the chance to escape way down south to Poole in Dorset at a holiday park set within mixed woodland which was brilliantly rich in fungi…

Suillus luteusIt was here I discovered Slippery Jack (Suillus luteus) and I don’t see many of them at all around the midlands. It is such gooey splendour to behold when you first find one. I’m guessing some people might dislike the slippery surface, but I just loved it, especially when it’s a key identification feature too.

Found exclusively in conifer woodland, especially with Scots pine you will be pretty sure what you have stumbled across. It is a medium to large mushroom and closely related to boletes, featuring pores instead of gills, but feature glutinous caps (to some degree or another) many of which have rings on the stem and grow along side conifers.

There were only a few I found with (I think) Larch Boletes which are very similar but lighter in colour, growing with larch – naturally. I didn’t check all trees around which I’m kicking myself about! But that’s a post for another time.

The chestnut/sepia brown sticky cap is unmistakeable. Slide your finger across, hold it for a second, then slowly pull your finger away. Nice brown glutin goo will want to come along with you. Great stuff. The small round yellow – straw yellow pores can become flushed a deeper brown colour.

And, as mentioned before, with most Suillus species, there is a ring on the stem. Depending on what age you find your Slippery Jack it can differ somewhat. Initially it is large and white/cream in colour. It will turn a deeper reddish-brown over time and maybe even fall off leaving only a memory of it’s presence! But key features to note are that ‘above’ the ring the stem is the same/similar colour to the pores underneath the cap, but below the ring is white, at least underneath sepia brown granulations and darker markings – so let’s just say darker!

There is no real distinctive smell or anything like that to make you want to pick and eat it, but it is edible and definitely worth a try. After peeling away the glooping covering they must be cooked and may shrink a little as they are very ‘watery’. OK, so you don’t have much left, but try it sliced in some omelettes or add as a pizza topping. And thanks to a recent comment (see below) it’s most common use is to dry slices of the cap (after peeling and cooking I presume) and then process into powder which is good to add to soups, casseroles and such. All good stuff.

QUICK ID TABLE: SLIPPERY JACK Suillus luteus

FRUITING BODY

5 – 12cm in diametre, Chestnut or sepia colour. More rusty colour when older. Brown slimy & sticky gluten on surface. Shiny when dry. Flesh is white.

STEM

5-10cm x 2-3cm. Ring on stem. Pale straw colour above ring at apex. White but discoloured darker brown with age. Ring initially large white/cream darkening to deep brown/sepia.

PORES / SPORE PRINT

Small and round. Lemon yellow / straw colour.
Spore Print: Clay – ochre(see how to take a spore print here).

HABITAT / SEASON

With conifers, usually Scotts pine in autumn. Common.

EDIBILITY

Edible but watery. Must peel slime off and cook before eating. Or dry and process into a powder for soups and casseroles.

The Genus SUILLUS (related to BOLETUS – the Boletes): Characteristics to look out for:

• Like Boletes, Suillus has pores on the underside instead of gills.
• Most have glutinous/slimy caps, especially when wet.
• Growing in association with conifers.

Bay watch! The Bay Bolete

The summer days so far have been a concoction of showery spells, the odd storm and quite a few blazing hot stretches. So even though it has been drier out there in the woods I still venture out. And today I was happy to find a great Bolete specimen.

Boletus badiusThe Bay Bolete (Imleria badia, previously Boletus badius) is one of the more common Boletes and fortunately one of the more tasty ones too. It can be found in all kinds of mixed woodland and has a season from July to November. So I was extra to happy to find one relatively early in the season.

Confusion with Cep or Penny Bun (Boletus edulus) and even the Suede Bolete (Boletus subtomentosus) is understandable, but the Cep’s pores do not turn blue/green on handling. The Suede Bolete does have blueing, but the velvety feel of the cap differs to the smoothness of the Bay Bolete.

Appearances (especially in size) can differ greatly from one Bay Bolete to another – Where they grow is one factor to consider. At first glance they look uncannily like Ceps when growing amongst pine needles on the woodland floor. When found growing in tall grass, they tend to have thinner and/or longer stems (and sometimes a slightly viscid cap) – just like this one here…

The cap can range in size from 4 – 14cm in width, the specimen shown here was roughly 11cm and was a lovely ochre brown colour, smooth to the touch but slightly sticky when wet. It’s stem which is streaked with the same colour as the cap, is cylindrical and smooth. It can grow up to 12.5cm and the thickness can range from 0.8 – 4cm.

Don’t miss out on the chance to grab a few as they’re great mushrooms to eat. It has a pleasant mushroom-like taste (smells mildly mushroomy too), and are especially more palatable when younger as the flesh is firmer. They are also good for drying too.

I’m sure more and more will pop up as the mushroom season starts to kick in. Enjoy…

Boletus badius - Imleria badia

The Bay Bolete – Notice the blue brusing on the pores when handled, and the slight blueing in flesh just above the tubes when cut in half.

Bay Bolete ID

The Genus BOLETUS (the Boletes): Characteristics to look out for:

• Have pores (open ends of tubes) on the underside instead of gills. Easily separated from the cap.
• Most have dry caps (viscid when wet – but not glutinous like Suillus genus).
• Most have reticulation on the stem; a fine network covering parts or all of the stem. Make note of the colour.
• When cut or bruised take note of any changes in colour to the flesh or pores.

Boletus badius

This Bay Bolete is growing in the middle of the woods. Notice the shorter/thicker stem.
