I have had this plant for more than 10 years now but I do not know its name. What is the name of this plant? The issue is that this plant has a lot of white areas, as shown in the pictures. These have been there for a long time now but I don't have any idea what they are. Perhaps it is a fungus?
In addition, one of the stems turned brown a long time ago. A couple of days ago, I tried to peel a small patch from that brown stem to check if it has a disease which I can recognize, and the stem underneath is still green.
