    That tree looks diseased, I'm sorry to say. The white material does not look like it's a precipitate, and the black spots definitely look fungal. Unfortunately I can not give you any more information than that as I'm not very well versed in what diseases affect species of Araucaria.

    Also, you might know this already but be aware that "monkey puzzle" is a common name which generally refers to the species that's the more cold hardy and can be planted outside in parts of the UK, but the species you have is sometimes mistakenly referred to as a "monkey puzzle" as well, but will not be hardy below 0 degrees Celsius. THe more cold hardy one is native to Chile, the one you have is Araucaria Bidwillii and is native to Queensland. It can easily be grown as a houseplant as well, though.

    May be scale insects of some sort. Try washing it off with a pressure hose; if the problem re-appears, then try a systemic insecticide.
