I was interrupted with a computer switch before finishing this a week ago so the specifics are not fresh, like lighting, which Pau solved in a similar shot with polarized fiber optics. I think I had to remove my diffuser plastic hood to squeeze light into this vertically mounted specimen on my horizontal rig in order to maintain reasonable shutter speeds of around 2 seconds.

Oly 20/2 at about 10x on 12MP full frame.
I did the stepping on the rear bellows standard this time which produced a fairly large change in magnification:


... but hopefully improved alignment problems that I've had with deeply overlapping features. Probably not much of an issue for this fairly flat subject though.
You can see a slight detail improvement between the upper left and lower right due to magnification change:


I shot 225 frames which was too many. It's easy to make small steps using the rear standard; no micrometer involved, just the bellows knob. This version is only 48 frames. I tried stacking the whole thing and there is a slight improvement:


... I might use every third shot if I did it again.
Also, I tried DMap with Zerene stacker, with the default contrast level of 74. That came out very clean with a little less highlight blowout and some transitions improved but it put all the background detail near the raised spore cluster out of focus so I stacked with PMax and they evened out nicely just like that. Minimal retouching needed. The background areas were a tad more hazy after the blend (I think), so maybe more work to perfect that with retouching in other situations.
