We have some kind of fan palm that we bought last summer. We brought it in the house when it started turning colder. Since then we have gotten many new leaves. So it is growing but we have some kind of fungus or bug on it and it's all over the leaves both sides and stem. They wipe off fairly easy but would like to know what it is and how do we get rid of it. The spots are small rounded and brownish in color. Any help would be appreciated. Thank you in advance
