Andrew Graham writes that, 'Autumn is a good time to keep a lookout for some of the approximately 15,000 species of fungus which can be found in the British Isles. They vary tremendously in colour, size, shape, and form and can be fascinating things to look at. A small number make good eating, but most are unpleasant or at best tasteless. A few are deadly poisonous, so never eat fungus unless you are absolutely certain of your identification and always wash your hands after handling any of which you are unsure.
'Species are associated with different habitats and species so looking for fungus in a variety of locations is a way to find a good variety. Warm damp weather seems to encourage their growth. Those to be found on the ground are often short-lived and start to decay quite quickly or start to get eaten by invertebrates. Bracket fungus, that grow in plates out of the stems of trees, may last for years, each season throwing out a new plate. When trying to identify fungus, note the colour and the cap’s underside. Whether this is made up of gills, pores or spikes can help to identify the family, while location and colour will help identify the species. Despite the variety, all mushrooms and toadstools are fruiting bodies, designed in different ways to shed spores.
'These spores germinate to create threads, called hyphae, which grow to form a network called a mycelium. This network of threads grows to permeate the soil or tree on which the toadstool grows. The hyphae absorb nutrients from the substrate in which they live and in so doing contribute to decomposition. Many fungi form a symbiotic relationship with the roots of trees and shrubs. However, others are parasitic and can be very destructive by taking nutrients from their hosts, eventually causing their death. Some mycelia can be very small while others can spread through large areas of soil and be very long-lived. One is thought to be more than 2,400 years old and covers more than 3.4 square miles, surely making it one of the largest living organisms on the planet.’
Two books about funghi that you may enjoy and find helpful, are Mushrooms and other Funghi of Great Britain and Europe by Roger Phillips, and the recently published Entangled Life: How fungi make our worlds, change our minds and shape our futures, by Merlin Sheldrake.
Thank you to all our members for supporting our first indoor meeting on 17 September - we are now full to our COVID-safe capacity so:
If you would still like to come, please do email firstname.lastname@example.org, as we may establish a waiting list
If you find you are unable after all to attend, please email email@example.com as well!
Dick will contact everyone who has registered with a 'joining instruction' reminder just before the meeting.
The last Field Trip of the season will be an Invertebrate Survey on the River Nadder, and we are very happy indeed to say that our Autumn/Winter series of indoor talks is also getting back under way with another watery topic, 'Things we can do for wildlife in the streams and rivers of Wessex'. Please go to Field Trips and Talks pages for details.
'Prince, Tom Waits and a prisoner ant pop up in a fascinating book about how fungi form our world.' writes reviewer Tom Kerridge.
It so happens that Abby's wonderful bird photos are shortly to be replaced with fungi - just to remind us that this is the time to look down rather than up for nature's wonders, like this bracket fungus on a tree on the Ackling Dyke near the Vitrell Gate. If you have a photo of fungi you'd like to share, do send them to firstname.lastname@example.org and go to our Reading List page for other ideas for the fireside.
