Giant Fungus Discovered in China
Small fragments have broken off the single giant fungusThe most massive fruiting body of any fungus yet documented has been discovered growing on the underside of a tree in China.
The fruiting body, which is equivalent to the mushrooms produced by other fungi species, is up to 10m long, 80cm wide and weighs half a tonne.
That shatters the record held previously by a fungus growing in Kew Gardens in the UK.
The new giant fungus is thought to be at least 20 years old.
The first example of the new giant fungus was recorded by scientists in 2008 in Fujian Province, China, by Professor Yu-Cheng Dai of the Herbarium of biology at the Chinese Academy of Sciences in Shenyang and his assistant Dr Cui.
“But the type collection was not huge,” Prof Dai told BBC Nature.
However, “we found [the] giant one in Hainan Province in 2010.”
The researchers were in the field studying wood-decaying fungi when they happened upon the specimen, which they describe in the journal Fungal Biology.
“We were not specifically Read more…
Tree-killing disease found in Florida
The Associated Press
MIAMI — The Florida Department of Agriculture and Consumer Services has positively identified the presence of a destructive disease that affects avocado trees and other trees in the laurel family.
State and federal agriculture experts say laurel wilt disease has been detected on three swamp bay trees in Miami Dade County.
The fungal disease is spread by the redbay ambrosia beetle.
If the disease spreads, it could potentially harm Florida’s avocado industry, which represents nearly $13 million to the local economy, with more than 6,773 production acres in Miami-Dade County, with some acreage in Collier County.
Red alert in Britain’s forests as Black death sweeps in
Millions of larches have had to be felled to prevent the spread of a lethal virus from Asia. Christopher Middleton reports from the bleak and bare hillsides of South Wales.
Just before Christmas, you could stand at the top of Crynant Forest in South Wales and not have a clue that there was a village in the valley below. Today, the view down to the little white houses is uninterrupted. Where in mid-December there were thousands of larch trees, now there is a mass of stumps and branches.
It looks like a photograph from a First World War battlefield. A featureless no-man’s-land, interrupted by the occasional blasted tree trunk, pointing at an unnatural angle.
And that’s just the start of it. Turn your gaze in any direction, and there is a scene of devastation. Bare hillsides as far as the eye can see; slopes that look as if they’re covered in bracken are in fact coated with fallen trees.
Meanwhile, piles of logs as tall as barns are stacked up neatly by the roadside, like casualties awaiting collection from clearing stations.
The force that swept through here was not a hurricane, but an army of tree-felling engines sent in by the Forestry Commission. Already they’ve cleared 380 acres, but there’s more to be done. Much more.
And they’re in a race against time. Across the country, some 1.4 million larches have been cut down in the Read more…
