Experts believe the organism, Gliocladium roseum, could potentially be a completely new source of green energy....

Scientists were amazed to find that it was able to convert plant cellulose directly into the biofuel, dubbed "myco-diesel' ...

Professor Gary Strobel, from Montana State University in Bozeman, US, said: "G. roseum can make myco-diesel directly from cellulose, the main compound found in plants and paper. This means if the fungus was used to make fuel, a step in the production process could be skipped.'

A reddish microbe found on the inside of a tree at a secret location in the rainforests of northern Patagonia could unlock the biofuel of the future, say scientists.

Its potential is so startling that the discoverers have coined the term "myco-diesel" — a derivation of the word for fungus — to describe the bouquet of hydrocarbons that it breathes.

"All of them have this big snag which comes in terms of replacing land that would have been used for crop growth to provide food," he said.

However, so-called "second generation" biofuels, such as myco-diesel, do not have that downside because they rely on cellulose, which can be provided by waste products.
