any useful books including Actinomycetes? - (Oct/14/2011 )

Am doing a research about the mycelial organization and cellular structure of actinomycetes, the problem is I can't find any information on the web about the cell structure, only some information in general without details…
Could anybody suggest a good book concluding actinomycetes in details???
I searched in some general microbiology books but….the same problem: there are no details.

What books did you check?
Did you check for example Prescotts microbiology?
Or Bergeys?
