".. alcohols such as phenol and ethanol are effective disinfectants because they readily penetrate cells and irreversibly denature their proteins." Madigan (2006, 52)

The rise of fungi v's coal?
Fungi externally digest compost by enzymatic actions.
If coal is a fossil record of a time before plant material was recycled like it is today,
what part did the rise of fungi play in this?

Collecting Fungi for Identification
Try to collect a range of individuals from immature to adult, and record colours and substrate.
Dig out the whole fungus, including the base of the stalk.
Wrap in greaseproof paper or place in brown paper (not plastic) bag.
A spore print is useful - cut off an adult cap (if present), and place gill-side down on a sheet of white paper; cover with a bowl or bucket for a couple of hours until the spores drop onto the paper.
Photographs are essential.
Caution: Many fungi are toxic. Avoid inhaling spores. Wash hands after handling fungi.

Basidiomycetes
p.16
"Though the exact biosynthetic pathways have been identified, no one knows exactly why these species produce the psychoactive alkaloids psilocybin (4-phosphoryloxy-N, N-dimethyltryptamine), psilocin (4-hydroxy-N, N-dimethyltryptamine) and baeocystin (4-phospgoryloxy-N-methyltryptamine)."
p.17
"..psilocybin is chemically converted (dephosphorylated) into more potent psilocin by the action of stomach enzymes (though the fate of baeocystin is less well understood)."
p.12
"..current estimates, 209 species of hallucinogenic mushroom.."
Copelelandia cyanescens - 'blue meanies'
psilocybe stuntzii - 'chipbark mushroom'
psilocybe cubensis - 'golden tops'. 0.63%, 0.6% & 0.025%
psilocybe semilanceata - 'liberty cap'
Letcher, Andy. "Shroom". 2006. London: Faber and Faber.
In Queensland specifically:
The toxic mushroom, Panaeolina foenisecii, may cause hallucinations, but interestingly the toxin is not known.
