DO not put shrooms into ethanol.  A chemist could use methanol to extract psilocine but the amount is not worth thee effort. in a one/eight ounce of shrooms, dried P. cubensis 3 and 1/2 grams equal 3,500 milligrams of poweder.  the amount of psilocine inthose 3,500 milligrams is 15-25 milligrams a nimute amount out of 3,500 and the residue would have to be put through a seive with methanol, not ethanol and it is not worth thei  rime or hassle since you could get sick uif it  is not fully evaporated.

I don't see why it would not work provided the boiling off does not oxidize it. I've done this with methanol and the extract was only 1/4 the original dry mushroom weight though, not 1/10, but I did exhaustively extract it.

Boiling off does not break down Psilocybin or Psilocin, they break down with decomposition at much higher temperatures (over 190 C ) and the boiling is only for 10 min or so.
Psilocybin is water soluble and Psilocin dissolves in boiling water.
Dephosphorization of Psilocybin into Psilocin happens in acidic solutions and around 70 C temp.
Oxidation of psilocin is not an instant reaction. Temperature (Boiling) does not "oxidize" anything, it just speeds up the process. Oxidation is a chemical reaction, boiling isn't.
The remaining residue quantity varies. Some shrooms, when dried ,lose 97% of fresh weight. I assume there's not much residue after a Methanol extraction.
Cubensis in general produce quite a bit more than 10% residue but after defating and precipitation of the proteins , it goes down quite a bit.
Subaeruginosa usually leaves less than 10%.
And of course, if the residue isn't dried properly....

As far as I understand , the solvent of choice (ethanol or methanol) depends on what one plans to extract. Psilocin seems to be soluble in Acetone,Chloroform,Ether ,Hexane,Methanol and slightly soluble in Water. Psilocin seems to be far less polar than Psilocybin and ,as mj said,in far less quantities in shrooms.
Any water extraction or water containing solvent extraction will also extract an enzyme that causes the Dephosphorylation of psilocybin into psilocin.
Psilocin undergoes oxidation quite quickly, thus rendering it inactive.
Ascorbic acid (Vitamin C) somehow inhibits (or slows down dramatically) the oxidation of psilocin.
The 10x stronger effect is arguable but has some possible explanations.
One of them is that Psilocybin has to undergo metabolic  Dephosphorylation in the body (liver ?) and a certain amount is eliminated during the metabolic phase.
If left in an slightly acidic water long enough (some say 60-90 minutes) , Psilocybin is Dephosphorylated  by the enzyme contained in the shroom , hence the tea has a higher content of Psilocin on ingestion and that leads to shorter come up times (there are reports indicating 5 min or less), stronger effects and shorter duration of the experience.
The tea trends to turn blue-greenish because of the oxidation of Psilocin.
Vitamin C inhibits/slows down the oxidation process as opposed to other weak acids (vinegar, etc)
"Rumor" has it that aqueous extraction with Vitamin C renders Keller reagent test and Mandelin test useless, they will not show any indication for psilocin or psilocybin so one needs to be aware when testing.
For the Psilocybin extraction, Methanol is the solvent of choice for most scientists who published papers on extraction of psilocybin because the enzyme that does the Dephosphorylation is not soluble in methanol (or possible very slightly soluble).
Ethanol absorbs moisture very fast thus it is not suitable for psilocybin extraction (water will extract and activate the Dephosphorylation enzyme).
Psilocybin extraction seems to be the preferred choice since it is much more stable , does not oxidize easily and can be stored for much longer in normal conditions (sealed container in fridge).
As mj said, small qty is definitely not worth the trouble.
