Another mystery growth in my tank!

[tjm80]

Does anyone have any ideas what this is? I know I have diatoms, but I'm talking about the darker spots, if you look in the bottom right hand part of the pic, you can see two "strings" but I took the pictures of the other 3 spots because they're bigger - but they have the same strings. It looks pretty slimy, and it's a dark dark grayish black color. I don't know if it's cyano or what.
