Im not techy enough to know what par is for what lighting, but undulata stays green for the most part when it is shaded or low light. in medium light it gets a nice redish orange color. Havent grown in "high light" so I couldnt sat, but give it a shot its a nice plant. Why not try some luteait gets a dark reddish brown color with stripes if it gets enough light very cool. I can sell you some undulata and/or lutea if you need some.
The fungus on the wood is usually only temporary. Idk where you got it but it could be a softwood and not hold up too well under water. If it feels "waxy" or you can easily push your fingernewails into it its probably not a good idea to keep. I do a lot of drift wood collecting and you learn what kinds work and,which ones dont.
