how much should an 1/8 look like?

i just bought mushrooms for the first time and i think i may have gotten shorted.
Can anyone describe what an 1/8th of dried mushrooms (in pieces about an inch long each) should look like (amount wise)?

 

it looks one of these:

 

those look pretty heavy

 

they all weigh in between 3,5 and 3,7g so yea, maybe a little bit over. The one on the left is the lightest one.

 

Get a scale. Simple hand scale will do.

 

I use one of those scales for weighing letters.

 

are u serious?! i have like 2x1.5 inch mushrooms (stems and caps)...
that looks like soooo much, i thought what i have was like 2 g's at least....
