Just yesterday I visited a field in which I had found and collected St. Georges mushrooms way back at the beginning of April. To my surprise and delight I discovered that a half dozen rings still included some viable mushrooms. Although most of the fungi was well past its best, like the last picture here, there where still enough good ones to take home for tea for the family.
The received wisdom is that mushrooms appear ‘over night’ and are gone just as quickly. True it depends on the species of fungi and the environmental conditions – Shaggy Inkcaps, for instance, on a wet day can be spotted in the morning and a pool of ink by lunchtime. Others have more staying power. But even I was surprised that these St. Georges where still going strong a good five weeks after I had first spotted them.
