What is this thing growing from my epi?

[JOHNnDC]

Gang, I'd posted this is another forum which, silly me, rarely gets me the quick and informative answers you guys do, so, belatedly, here goes :-)

I've had my little Epi Elfin for almost a year now and it hasn't done squat. No growth, nothing. All it's done is slowly lose most of its leaves to this very strange black fungus-looking leaf thing that I've mentioned here before to you guys.

Well, there was this little pseudobulb looking thing next to the newest PB, doing nothing since I got the plant, and now all of a sudden it's opening up and growing something or some things. What in God's name is this thing doing? I've not seen any of my other orchids grow like this - is this how a new PB grows, or what is it growing? LOL

Thanks, JOHN
