However I think sempei fi hit
the nail on the head.
God gave them manna to eat.
Then later the people complained,
it displeased the Lord God of Israel.
In Numbers 11 verse 7 ,8
It discribes the manna, and
how they cooked and ate it.
It does not sound like mushrooms.
But They started to complain,that they
only had blah tasting manna to eat.
6But now our soul is dried away:
there is nothing at all, beside this
manna, before our eyes.
The manna was able to sustain them
with nutrients, but they grumbled.
When we get to the Quail, it was a
separate issue then manna, that
was a test of the 4th commandment.
Besides breaking the commandment,
They complained about the manna and
wanted real food like back in Egypt.
18 And say thou unto the people, Sanctify yourselves against to morrow, and ye shall eat flesh: for ye have wept in the ears of the Lord, saying, Who shall give us flesh to eat? for it was well with us in Egypt:therefore the Lord will give you flesh, and ye shall eat.
The quails [flesh] was only for a month.
But Manna sustained them for 40 years.
Mushrooms would not sustain them.
Sin here was for complaining, and gluttony.
Some of those God killed, because of this.
"And they tempted God in their heart by
asking meat for their lust."
"and slew the fattest of them" -as examples.
Numbers 11:34 "And he called the name of that
place Kibroth–hattaavah: because there they
buried the people that lusted. Philippians 3:19
The quails and manna are separate issues,
And are described different. Quail was quail,
Manna was bread from heaven.
Was that the nail on the head?
