The leaves look dehydrated either from lack of regular watering generally
with too much heat or lack of roots from overwatering (due to rot). From
your picture background, I also assume you are keeping the plant at room
temp (which of course can vary tremendously) which is generally not good for
masdevallias. They need more humidity and cooler temps than are generally
considered room conditions. From the looks of the plant, it is large enough
to recover if placed in more favorable conditions with watering gradually
brought back up to normal. Don't try a drastic move or you'll probably lose
the plant. If it declines further, you might consider repotting into a
smaller pot, trimming rotted roots and stems.

I'm afraid that I've killed my first orchid. I purchased it at an
orchid show in San Francisco last year, and it's been getting steadily
worse ever since. I've taken a few photos of its current state
(www.airpork.com/masdevallia) and I'm wondering if anyone could tell
me whether or not it's beyond hope. If it can be revived, do I need to
just get it back on a regular watering/feeding schedule, or will it
need new medium? I think it's in sphagnum moss now.

Thanks in advance for any help anyone can give a complete orchid
newbie.

Regards,

Ben
