though maybe it's here!

I have a gorgeous orchid that i got from my grandmother's greenhouse -- I'm sorry to say i didn't photograph it while in bloom, all i can tell you is it is not from the phalaeonopsis family and does not have pseudobulbs. the flowers grow about 8-12 apiece per stalk and started out purple and faded to white before withering....really stunning.

anyway. when i got it, i noticed brown, raised splotches on the leaves. the splotches are firm and are about the size of a tictac, or larger. any idea what these are, if they are harmful to the plant, and if so, how i can deal with them?

thanks much!
