The first sounds like BGA, just in black form. The usually cause is low nitrates. Also try increase water flow. Just keep it removed manually & get your water chemistry balanced.

The second could be green dust algea, which is not always completly green. However it does scrape off easily. However I have found that the red takes a little more effort to get off the glass. Again make sure that you are keeping balanced tank:ferts, C02, lighting & maintenance.
