Larch Bolete (19/09/2015, south-east Sussex)

Given the length of time that mycologists and foragers have been watching fungi, you might think we would have a pretty good idea if there’s going to be a good year or a bad year and be able to predict what they are going to do. If so, you’d be wrong. This is actually part II of the mysterious case of the missing mushrooms – part I was the second half of last autumn. In that case what happened was an extended dry spell from mid-September to late October. That this led to a lack of fungi isn’t remotely mysterious; fungi need moisture or they cannot produce fruit bodies. The mystery was their total failure to recover when the rains finally came. I expected November 2015 to make up for the disappointing October, but the situation actually got worse, and by the end of November there was nothing to be found, even though the usual season-ending hard frost hadn’t happened. My most successful outing of last autumn was exactly one year ago: September 19th 2015. Today I returned to the precise locations I visted that day and I found sweet fanny adams. And it is not just some species that are missing; it’s almost everything apart from a few wood-consuming bracket fungi like Giant Polypore and Beefsteak Fungus. This is particularly strange, since last year’s poor showing might have been expected to be followed by a bumper harvest this year. A further element of strangeness is a geographical inconsistency – in the northern half of Britain there is a completely different story unfolding. Judging by the photos and the words of mouth, the start to the mushroom season in Scotland and northern England is at least average and in some places very good indeed.

Fly Agaric (19/09/2015, south-east Sussex)

I won’t pretend that I know what is going on, but my best guess is that it is a combination of temperature and soil moisture. We’ve just had the highest September temperatures for over a century, and my home territory lies just on the border of what botanists call “hardiness zone 9”. Most of the UK is in the colder zone 8, but the south west and the areas immediately adjacent to the south and west coasts of Britain are warmer. This is due to the sea acting as a temperature buffer: daytime highs are slightly lower and nighttime lows are slighty higher. The result is that while the average lows further north have fallen below the level that triggers most of the autumn fungi to fruit, in the far south the fungi still think it is summer. Although it is more complicated than that, because what I’ve been seeing over the past two weeks is one fruit body here and there – one Deathcap, one Blusher, or as today, one Scarletina Bolete (spotted from the car, growing by the side of a road). This suggests that soil moisture content is also playing a part, even though we have had a reasonable amount of rain recently. I won’t pretend that I know what is going to happen next either, but my best guess is that it is just taking a while for the fungi to respond to recent temperature falls and heavy rain, and that within a week or two there will be fungi all over the place. I certainly hope so, because I have got a busy October ahead of me.

Penny Bun / Cep (19/09/2015, south-east Sussex)

Speaking of which, it is probably worth reminding people of some important dates and events which still have free spaces.

Firstly, I have just added another extra date to my fungi foraging sessions in Hemsted Forest (west Kent), due to the others being booked up. This will be on Saturday November 5th (see fungi foraging link at the top of the page).

There are still places available on the fungi foraging workshops on Sat/Sun 8th/9th of October at Bay Tree Cottage in Northamptonshire, and the fungi foraging day and chef-prepared meal on Sun 16th of October at Catthorpe Manor in Leicestershire.

There will be a book launch event (free) on Sat Oct 22nd at Bookbuster, Queen’s Road, Hastings. This will include talks at 6pm and 7.15pm, and signed copies of the new book will be on sale.

There will be another launch event on Fri Nov 4th at The Garden House in Brighton, East Sussex. The launch event will include a display of a wide variety of fungi, signed copies of the book will be available, and it is followed by a talk, a tasting session and a meal (see their website for details).

Dark Penny Bun, Take Two

I have a confession to make. I had to remove my previous blog entry because it contained an error – and those can be serious in this line of business. However, there’s some lessons here. The first is that not all fungi foraging mistakes are equal – if you’re going to get something wrong then the difference between mistaking a delicacy for another delicacy and mistaking a poisonous species for a delicacy is also the difference between a tasty dinner and your last dinner. It was not good fortune that my mistake was the former rather than the latter, but the result of knowing that even if I got something in this region of fungal taxonomy wrong, I wasn’t going to end up being poisoned. It was a mistake nonetheless, and so this blog post will retrace the steps that led me astray.

I’ve long been aware of the existence of three mushrooms very similar to a penny bun (Boletus edulis, cep, porcino). All three are much rarer, at least in southern England, and all of them highly prized – at least as much as their more famous relative, and one case even more so. The three in question are the Summer Bolete (B. reticulatus), the Dark Penny Bun (or Dark Cep, B. aereus) and the Pine Bolete (B. pinophilus). As the years marched on and I continued to never find any of them, I started to wonder whether maybe I’d seen them many times and had been mistaking them for a Penny Bun. I mean…exactly how similar where they?

Penny Bun (Boletus edulis)

Then two things led to my first mistake. The Summer Bolete does not always fruit in the summer, and its name comes from the reticulations on its stem – a network of raised lines. I came across a couple of pictures on the internet claiming to be B. reticulatus, showing a clear, white network of lines on a mushroom that otherwise looked exactly like a bog-standard penny bun. “Ah”, I thought, “so I’ve been picking these up and just not realising what they were. Now I know what a Summer Bolete is.” Except I didn’t. My picture (left) is not of B. reticulatus. It’s just a penny bun with a particularly noticeable network of reticulations on its stem.

And when you’re working by a process of elimination – which is sometimes a legitimate strategy when identifying fungi – then one mistake can lead to another. When, two weeks ago, I found a mushroom with a light brown, suede-like cap, and white pores, I ended up concluding that it had to be B. aereus – it didn’t look dark enough, but then again some of the pictures I could find of that species had caps as light, especially when they were quite small. So I blogged about Dark Penny Buns.

Summer Bolete (Boletus reticulatus)

Then a few days later I found lots more of them – outside a pub where the landlord had taken a dislike and dumped a load of earth on them, in a futile attempt to stop them popping up on his land. At this point, with more specimens as examples, it dawned on me what had happened. These couldn’t be B. aereus because they were the wrong colour. Dark Penny Buns have to be Dark. So they had to be B. reticulatus, and what I’d thought was that species were Penny Buns. The network on their stems is much finer, and brown rather white.

Dark Penny Bun, or Dark Cep (Boletus aereus)

Then, in a twist so typical of mushroom foraging, something else turned up. Yesterday I visited a site where hedgehog fungi grow in great profusion every year, collecting for two foraging workshops in Northamptonshire. They were there as usual, but this time they had a friend – a solitary, dark-capped mushroom that otherwise looked remarkably like a penny bun. And by now you will have guessed where this story is going: this really was a dark penny bun. And it really was delicious.

As for the fourth member of this quartet – the Pine Bolete? That remains on the “to find” list, but the way this autumn is going, I wouldn’t be surprised if it turns up next week.

27/11/2015: UPDATE

The fourth member of the quartet has turned up. Where? On the banner at the top of my main page, of course! I’ve been mistaking Pine Boletes for Penny Buns, it seems.

Penny Bun (Boletus edulis, Porcino, Cep)

Re: my last blog post: OK, I was wrong, the pundits were right this time and the much-anticipated “penny bun storm” appears to have arrived. It’s perhaps a little later than expected (although the mushrooms rarely do what people expect them to do), but there is now no doubt that 2013 is going to go down as a very good year for Boletus edulis, otherwise known as a Porcino or Cep, and the most important commercially collected species in the world. I have in the last week seen numerous pictures posted from all over the UK of large collections of this species, mostly in excellent condition. And in those places where other people haven’t already been out picking, I’m finding plenty myself.

Lurid Bolete (Boletus luridus)

It is also looking like a pretty good year for most of the good edible species. I’m finding more chanterelles (Cantherellus cibarius) than usual, very abundant fruitings of Parasol Mushrooms (Macrolepiota procera), Giant Puffballs (Calvatia gigantea), Hedgehog Mushrooms (Hydnum repandum) and also a wide selection of other boletes, especially the Penny Bun’s “poor relation” the Bay Bolete (Boletus badius). This morning I also found a lovely collection of what are arguably the most beautiful of the pored mushrooms, the Lurid Bolete (Boletus luridus). They almost look too pretty to eat. Be careful if collecting, because there are some poisonous red-pored boletes – this is not the easiest branch of the family as far as safe collecting is concerned. An important identifying feature of this particular species is the persistent red line just above the tubes when cut. Also note that they are poisonous raw, and need to be well cooked.

All things considered, 2013 is shaping up to be a bumper year for fungi (a claim that is made every year in some quarters…this year is actually true). The season is likely to peak over the next three weeks so get ready for what is likely to be a glorious October for fungiphiles!

Peak of the mushroom season 2011:

Late November 2011, as the mushroom season peaked. Normally it’s earlier, but October 2011 was far too hot and dry for fungi.

These fungi, all of which are edible, were all collected in one afternoon at various locations throughout Sussex. It’s not a normal day’s haul, either in terms of variety or quantity. Days like this only come around once in a couple of years, when the conditions are just right. It also helped that the peak of the season was late in 2011, and I already knew where to go to find a lot of this stuff. I also ought to admit that some of them were picked more for their aesthetic qualities (I wanted a good picture!) than their desirability for eating. I should also assure people that I did not strip the locations concerned of all the edible fungi. No more than 50% of the fruting bodies were taken. There just happened to be fungi all over the place that day, and the situation was also helped by the fact that the peak was late that year, and that many would-be foragers had given up on the mushrooms that year after the worst October for fungi that I can remember.
