Some New Book Reviews

Looking at my statistics page, the page entitled ‘Book Reviews’ appears to be quite popular. I hope this is because they are good and not just because the page is the second one after ‘Home’. I have realised that I don’t get quite so many page views after ‘Book Reviews’ though…

Anyway, here are some new book reviews. They will also be available on the ‘Book Reviews’ page.

Title: The Lichen Hunters
Author/s: Oliver Gilbert
Summary: This is a lovely collection of tales from the point of view of an experienced lichenologist, Oliver Gilbert. It retells stories from places like remote islands and mountains, the Lizard and various churchyards. This is not just a dry book about lichens, it is often exciting and even terrifying and spooky in some places! Unfortunately Oliver passed away in 2005, but this and other books by him will hopefully be a long-lasting legacy.

Title: The Carabidae (ground beetles) of Britain and Ireland
Author/s: Martin L. Luff
Summary: This is one of the few great detailed books for people wanting to identify what ground beetles are around them. I find that constant referral to the diagram of the beetle anatomy is needed, so some beginners might find the jargon quite confusing. However, once you successfully get to the end of the key, there is a lot of information about the beetle you have identified. This is a feature I don’t often see in keys like this and it is an easy way to check your identification.

Title: Concise Guide to the Moths of Great Britain and Ireland
Author/s: Martin Townsend and Paul Waring (Illustrations by Richard Lewington)
Summary:This is an easy-to-use, concise guide which is perfect for the beginner, the amateur and the professional. The illustrations are incredibly detailed, which is often needed for this type of identification, all done by “one of Europe’s leading natural history illustrators”. The wiro-binding design lets the book sit permanently open whilst you are peering at a moth, very convenient in the field along with the ‘waterproofness’!

A Microscopy Workshop: a great day out!

On the way to Wales this summer (see Teifi Marshes, home to the Welsh Wildlife Centre) I stopped off at Brunel Microscopes Ltd.’s HQ in Chippenham to look for a microscope that would suit me best. I bought a microscope mainly for looking at fungi spores and other fungal structures, but I also look at other things like the leaves of Fissidens spp., a genus of mosses which are absolutely tiny. I’m still getting used to using the microscope, so today I went to a beginner’s microscope workshop in Great Bookham run by the West Weald Fungus Recording Group.

I was asked to bring my microscope to the workshop, so I did, but I left the stuff like the prepared slides, pipettes, coverslips etc. behind thinking that I wouldn’t need them. However, that turned out to be a mistake as I took just a few minutes to set myself up, whereas others started unloading whole dissection kits, oil immersion, all the chemicals and stains… at least there was a plate of Jaffa cakes to keep me busy!

The day started with a talk by Maurice Moss, who used to be a professor at Guildford University. He brought in two microscopes, one a dissecting microscope for larger objects like feathers and moths and the other a standard one like the one I have to look at fungi. He taught us all about how polarising filters can be used to look at colours in crystals and the colours the filters produced were phenomenal. He also let us look at some of his prepared slides, such as a peacock head feather, which again had superb colour.

After Maurice’s talk we chatted amongst ourselves about fungi (and other things!) and some people were able to recommend some useful tools and books. Many were quite surprised that I had no books whatsoever, and they had no hesitation in recommending “Mushrooms” by Roger Phillips. This looks really good and I think it will be a good purchase if I can find a copy , as well as a key to the genus Russula (a tricky genus) by Geoffrey Kibby, who regularly comes along to WWFG meetings.

After lunch was a talk by Barry Hughes, the author and photographer behind the Collins Fungi Guide. Many of the photos included in the book are taken in Surrey and West Sussex! He did a talk on spores and he handed out a few spore prints for us all to look at. He then asked us to look at them under the microscope and decide what shape they were using a sheet he handed out. My spores were from the genus Inocybe and almond-shaped! I learnt that there are a few tests you can do on spores to help identify it. You can see if the spores are amyloid, dextrinoid or neither by applying iodine using Melzer’s reagent or Lugol’s solution. If the spores turn black to blue-black when exposed to the substance then they are amyloid and if they turn reddish-brown then they are dextrinoid.

Other tests you can do include:

  • Putting a few drops of household ammonia onto the flesh of the fungus. The fungus might or might not have a reaction; if it does then the colour the flesh turns aids an identification.
  • A fun one: the gills of the genus Lyophyllum turn blue with Paradimethylaminobenzaldehyde.
  • When potassium hydroxide (KOH) is applied there is a colour change in some fungi, including agarics and boletes.

At the end of the afternoon, I had a really informative day. I learnt lots of new skills which hopefully I will soon be applying back home. I also had the chance to meet some really great people who love to share their interests.
