Fungi Biomass -> Oil?

I'm curious if anyone has done any research on using fungal biomass for fuel. It seems to me that mankind has exploited all of the other eukaryotes in the "burn life for energy" quest except for the fungi (other than those we eat). Why is this? I mean, that is JUST the fungi's game!
This link offers an abstract describing the autoclaving of fungal cells from Mortierella ramanniana var. angulispora, IFO 8187 at 250C resulting in an oil with a viscosity of 100 mPa.s and gross calorific values of 36 kJ/g. http://cat.inist.fr/?aModele=afficheN&cpsidt=4492837
That would put it at, what, 36MJ/kg or 36GJ/metric ton. Google's calculator says this is about 34MBTUs. Some quick searches gave the following numbers for other energy sources:
1 ton coal = 16,200,000 to 26,000,000 Btu 1 ton wood = 9,000,000 to 17,000,000 Btu 1 standard cord of wood = 18,000,000 to 24,000,000 Btu
The other things fungi has going for it is that it eats what we would normally consider waste material, even cellulose!
Here's a news article about cultivation of fungus found in elephant dung as a method of breaking down hay and straw.
http://today.reuters.com/news/articlenews.aspx?type=oddlyEnoughNews&storyid=2007-04-18T135228Z_01_KUA849907_RTRUKOC_0_US-BIOFUELS-ELEPHANTS-ODD.xml&src=rss&rpc=22
I would presume we can run an SVO vehicle off this oil and could further esterify it into biodiesel.
So my question is, has anyone here tried thermal depolymerization of leftover fungal biomass? Has anyone intentionally cultivated Mortierella spp.? Does Psilocybe spp. produce similar quantities of oil?
Are the energy inputs to this process more expensive than the outputs?
Would this only be useful for materials we can't easily turn into higher ordered fuel (like sawdust, trees, etc.)?
Seems to me like a fungal route to biomass energy is better than algae that requires light. Is the downside that fungi breath oxygen (i.e. it would increase CO2 emmissions)?
If our current oil reserves come from dead plankton/algae, dinosaurs, etc., wouldn't fungi have decomposed those things? Is it fair to say we are burning up dead plants and animals or would it be more correct to say we are burning up the fungi that ate their carcasses and bacteria that ate the fungi? I have read about a fungal bloom after one of the extinction events, so maybe we are already using fungal oil and don't even realize it.

Gah.
Fungi are decomposers. Unless your biomass is photosynthetic you're bootstrapping. It only makes sense for converting less-useful biomass into more-useful biomass, but in that case, why not just cultivate useful biomass (e.g. corn, soy, what have you)?
Getting a car to run off of wood (processed with fungi into oil) is no different, environmentally, from burning wood. Carbon is carbon is carbon. What you're describing is basically just a roundabout sort of refinement, not a truly novel energy source.
Definite waste of time, I say.

Fungi and bacteria are have been used to produce ethanol from biomass. That's as close as you're going to get.
It's interesting stuff. I'm sure they'll continue to perfect the processes.

also mass producing fungi would be unrealistic to try to produce another Major fuel source. good idea tho.

I saw in a video put out by Darryl Hannah and Paul Stamet's had trademarked a myco ethanol fuel called Myconol. Doe's anyone else have any info about this. I haven't seen anything else about it other than from that one source.
