You said "no forward gears". I take a guess you did try reverse and moved the bike? That eliminates the driveline.
I am going the other way . You said the master cylinder had a lot of black stuff. If there is a wad of that in the slave cylinder perhaps the piston is stuck in the disengage position. Also though very slim , there is a chance the rubber fluid line is failing internally. It could act as a check valve and be holding hydraulic pressure, but doubtful.

I would remove the slave cylinder and see if the trike will roll freely when in gear and pushed by hand.
Lets work externally before jumping inside.

Yes, the clutch falls like it did 20,000 miles ago

This is defiantly a possibility. I remember back in high school, I had a '69 Catalina. After school on day, I stopped at a buddy's house. When I went to leave, I couldn't move as the left front brake caliper stuck.

I took off the slave cylinder and tried putting it in gear. The tires still don't turn. Any suggestions now. Is it the clutch?

It has to be a shot clutch. Either the disks are cooked or there's a mechanical failure.

Have you looked at the output shaft? I think Honda calls it the final shaft.

Like I mentioned before, a complete failure of the damper plate might do this but maybe other clutch pieces could too. They are dealing with the additional load of the trike.

Seems like, if the clutch was the culprit, it would still have enough force to overpower your hand.

Why ain't we ridin'?

Since removing the slave cylinder did not succeed in applying the clutch I would now think it is an internal problem. Of which it could be many .
There could be problems with the multi disc assembly or the clutch diaphragm spring may have failed .That spring failure, would release the apply pressure on the clutch pack.
Another fail point I see could be the damper spring on the output shaft. Looking at the photos in the service book, if that coil spring was to break, it could disengage from the final driven gear. Though I suspect that would lead to a knocking/clicking noise.
Wish I could offer some other simple theory to try

The lifter plate turns freely without the clutch disc turning. Is this right

If you can turn the lifter plate without the outer clutch hub turning it is effectively disengaged as I view the service manual photos. To me this goes to the diaphragm spring I mentioned in my earlier post.
Understand , I do not have a clutch assembly in my hands. I am only reading the service book and photos.

I hope the following (my understanding of the operation) helps clarify the operation of the drive system- crankshaft to output shaft.
Turning the lifter plate is turning the steel plates in the clutch pack . If the clutch assembly is engaged, the diaphragm spring is applying pressure to the pack. Turning the lifter plate to an engaged clutch turns the steel plates which are bound to the friction disc by the diaphragm spring pressure, thus connecting it to the outer clutch basket.
The outer clutch basket is driven by the crankshaft. When the clutch is engaged, it turns the inner portion of the clutch basket(steel plates) which drives the mainshaft.
When a forward gear is selected and the clutch is engaged it turns the mainshaft which turns the countershaft, which powers the output shaft.
