Skipping Space Jump: Fungal Hall A

Notes:

When you first enter the room, kill all the Hunter Metroids (original NTSC) or all but the one in the middle of the room (PAL).
Fall down to the bottom of the room and do a DBJ up to the mushroom lowest to you. Now, do a fairly easy HBJ onto the next mushroom. Now look back to where the metroid was that you killed, and pray the he dropped a powerup. If he did, scan dash off of it and to the platform the other Hunter was guarding. Hop up these platforms and freeze the Hunter that is now nearly below you.
You will need to do this next part fairly quick, so dash off of the grapple point to the platform where you'd usually L Jump. If he defrosts, freeze him again, and use that time to line yourself up with the very edge of the platform, and look back up and use an "R-Dash" to get a fair bit more distance and you should make it to the next platform. It helps to hold backwards during the dash to bend it.
Alternatively, you can unplug your controller, hold down L, then when the glider is where you need to be to dash off of him, hold on and do an R dash.
