Revised and Enlarged Second Edition – Fascinated by Fungi

Fascinated by Fungi, by Pat O'Reilly

I am so pleased with this new edition, available from July 2016. It’s a 450-page hardback and includes the latest updates to taxonomic names (mainly as a result of recent DNA sequencing research) as well as new sections on Slime Moulds (yes, you are right: they aren’t really fungi but they are fascinating nevertheless!) and many additional pictures and species descriptions. I am particularly delighted with the greatly extended section on microscopy, with some helpful hints and tips for anyone new to choosing and using a compound microscope for studying fungi spores, cystidia, hyphal structures etc and some stunning photomicrographs contributed by world-class experts.

Most of all I wanted to let you know that First Nature are currently offering this new edition at a substantial discount on the RRP. For a limited period you can get the new, larger edition in a beautiful hardback binding for less than the RRP for the original paperback version here…

Maltese Fungus found by fungi hunters

Take a look at this bunch of weirdos…

Maltese Fungus Cynomorium coccineum

It’s an organism commonly referred to as Maltese Fungus, and from its general appearance you might think it is a relative of the various kinds of earthball fungi (Scleroderma species or Pisolithus species, for example), but no… this strange eruption from dry rocky soil is in fact a plant, and one of the rarest of Mediterranean species. Its scientific name is Cynomorium coccineum, and we found it (with help from our friend Finn Rasmussen, who discovered a colony in the same area a month or so go) on the Algarve clifftops near Albufeira.

Okay, now back to fungi hunting…

Red Cage Outrage

Searching for Morels in perfect Morel habitat in southern France at the ideal time (late April), I found a total of zero. Rien. Zilch. Nothing at all in the way of fungi… except lots of very stinky Red Cage fungi Clathrus ruber. One colony, covering about 10 square metres, contained at least 30 fruitbodies, from early egg stage to ripe and rancid with flies munching the spore-laden gleba so eagerly that even the presence of a camera lens a few cm away would not deter them. Well, it was a roadside picnic site…


The mad Morel search continues…

Update on our Server Upgrade and Googlegeddon… and a fine Easter Bonnet

Where have all the blog posts gone, long time passing…

Gone to outer ether-space every one – well, at least every one of my posts since 2012. All posts between 2012 and early 2015 appear to have been lost in a switch of web server… sorry about that. I’ll try to backup more competently from now on…

Meanwhile the ongoing blog silence has been due to every available moment being dedicated to making ‘mobile friendly’. Because our 2000+ pages were created over a 20-year period, the layout codes were far from consistent, and this has made the update process a very time-consuming one. Pages should work with legible text, auto-resizing pictures and no need for horizontal scrolling whether viewed on smartphones, tablets, desktops and super-large screens. We think the job is just about completed… but if you do find a page with a fault please, please let us know by emailing enquiries @ (but omit the spaces either side of @, which are here to make life just a little more difficult for spamming robots).

Finally, here’s a rather nice mushroom picture – after all this is supposed to be a fungi blog…

Reds driven north by climate change?

During August 2012 I have received news of a number of sightings of Clathrus ruber, the Red Cage or Lattice fungus, much further north in Britain than in previous years. Nearly all appearances of this strange-looking fungus in the past have been in the Chanel Islands, the Isle of Wight, southern England or (very rarely) along the south coast of Wales. It’s a Mediterranean mushroom, and far more common in the Algarve than in Aldershot!

Clathrus ruber, seen at Daventry, Northants, UK in August 2012

Has climate change enabled the spores to survive winter in northern England? A large group of Red Cage fungi sprung up recently in Daventry, Northamptonshire, and now I have received news and photographs of a fine but so far solitary specimen in a garden nead Huddersfield, in Yorkshire. At this rate these colourful, weird and very smelly members of the stinkhorn family, Phallaceae, will be over Hadrian’s Wall and fighting it out with Scotland’s armies of midges before long. Wish them luck!

Full taxonomic, distribution, habitat and identification details and together with more pictures of Clathrus ruber are online here…

Biographies of the Great Mycologists

Lucien Quelet, mycologist

Lucien Quélet

If you take an interest in fungi, it won’t be very long before you are reading some of the serious scientific works on the subject of mycology. I did say reading… not necessarily understanding. The trouble is that, like anything else you might try to learn about – whether it be birdwatching or stamp collecting – the science of fungi is shrouded not so much in mystery (although mushrooms certainly are mysterious organisms) as in its own almost impenetrable jargon. Technical terms such as ‘cystidia’ and ‘infundibuliform’ can be looked up in a dictionary or Googled for guidance, but rarely do we find all that we need in one place. The same is largely the case with the history of mycology and, in particular, biographical details of great mycologists of the past: coverage is either superficial to the point where dates of birth and death are virtually all you get to know or, at the other extreme, you have to plough through pages of details of early childhood illnesses, preferences for plums over cherries, or whatever the author has been able to exhume (no corpse pictures in my own research so far, thank goodness!) and decided to fill the page with.

Having decided that what I most wanted to learn about was what an authority had contributed to the body of scientific knowledge and in what circumstances they did so – many had demanding careers outside of science and biology, but yet contributed enormously to what we know so far about the kingdom of fungi – I thought ‘Surely I cannot be alone in this need’. Hence, over the past few months, I have been gradually adding biographical details of mycological giants of the past to the fungi section of and I hope that the new pages will be a helpful start for anyone else seeking similar enlightenment. Famous French mycologist Lucien Quélet (1832 – 1899) is the latest addition to the Hall of Fame. His page is online here…

As well as naming and describing many fungal species (and despite recent rigorous assessment based on molecular analysis most of them have retained the names that Quélet gave them) Lucien Q is immortalised by two mushroom species that are named in his honour. One is Boletus queletii, a pored woodland bolete, and the other is Russula queletii, another woodland species, commonly referred to as the Fruity Brittlegill. Here is a picture of the latter:

Basidiolichen on the Migneint

Lichenomphalia umbellifera the Lichen Agaric Getting on for 20,000 lichenised fungi (usually abbreviated to ‘lichens’) are known, and nearly all of them have an ascomycete (spore shooter) fungus as the mycobiont. Just a few dozen have basidiomycete (spore dropper) mycobionts, and these kinds of lichens are therefore referred to as basidiolichens. Half a dozen or so basidiolichens are found in Britain, and I saw one of them in early July 2012.

I had gone with colleagues from the Countryside Council for Wales and the National Trust to see some of the work going on to restore upland peat bogs on Migneint, a huge mountainous area in North Wales. Much of the work involves blocking up drainage ditches so that these vast upland bogs remain wet and so act as carbon storage reservoirs. (When peat bogs are drained the stored carbon, comprising dead sphagnum moss and plant debris built up over thousands of years, dries out and releases much of its carbon into the atmosphere as greenhouse gases.) There are many other ecosystem services from  ‘healthy’ upland bog habitats, including maintaining vital river flows during periods of severe drought. We are not in drought-worry mode in Wales this summer!

Close-up of the LIchen Agaric

The Lichen Agaric requires a sphagnum moss habitat

Growing in the sphagnum moss were pale ochre mushrooms that looked quite similar to Loreleia marchantiaethe Liverwort Navel – a small funnel-shaped cap-and-stem basidiomycete that grows on Umbrella Liverwort. These were rather paler, though, and on close inspection I noticed that the fungal fruitbodies were sprouting from green algal blobs on the stems of the sphagnum. They were, I realised, Lichenomphalia umbellifera – something that I had been hoping to see one day. (They are not rare, but they certainly don’t occur everywhere.) The fungal fruitbodies of this species, which some people call the Lichen Agaric, are cap-and-stem gilled fruitbodies related to the waxcaps, Hygrophoraceae.

With Fascinated by Fungi launched and so well received both in reviews and by the hundreds of people who have bought copies in the first six months of its availability, there is now a bit of time to update this blog, and in the wettest spring I can remember there ought to be plenty of grassland and woodland fungi around. Judging by the number of request for help in identifying fungi, many people are noticing mushrooms and starting to take a real interest. If you are a newcomer, then do take a look at where there are identification guides, a glossary, advice on safety, forays and loads more. If you already a seasoned fungiphile, here’s even advice on getting started in microscopy, understanding scientific terms, the ICBN classification system, and authirty names – plus brief biographies of several famous mycologists of the past..

What would be really nice would be to have your suggestions for improvements or new features that would make the site even more useful. More than 400,000 people a year visit the website and we do receive a lot of help already, so thanks very much if you have already sent us your suggestions, questions or contributions.

Fascinated by Fungi – a great new book from First Nature

We had a tremendous attendance at the launch of Fascinated by Fungi, Pat O’Reilly’s amazing new book. More than 150 people turned up for the launch at the National Botanic Garden of Wales on Saturday 24th September 2011, and among them were several noted experts from the world of mycology including David Harries the county recorder for Pembrokeshire, Nigel Stringer (who needs no introduction to fellow fungi enthusiasts) and Ray Woods, who ranks among the all-time greats in communicating a fascination with the kingdom of fungi to those of us with a much more limited experience of mycology.

Dr Rosetta Plummer, Director of the National Botanic Garden, opened the proceedings and welcomed people to not only the book launch but also the exhibition From Another Kingdom, a mushroom cookery demonstration by Gary Whiteley of Maesllyn Mushrooms, and special mushroom menu in the on-site restaurant, and after lunch a fungus foray that despite poor weather attracted a huge following and was acclaimed a great success. Many thanks to Bruce Langridge and Ray Woods, who held the participants spellbound throughout the foray.

Roger Thomas, chief executive of the Countryside Council for Wales, formally launched the book, which he confidently expects will become essential reading for anyone, whether a lay person or a professional mycologist, with an interest in fungi.
