OSHA guidelines for exposure to aluminum:

Quote:
* OSHA PEL The current Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) for aluminum is 15 milligrams per cubic meter (mg/m(3)) of air for total dust, and 5 mg/m(3) for the respirable fraction, as an 8-hour time-weighted average (TWA) concentration [29 CFR 1910.1000, Table Z-1].

Quote:
There is some evidence that Alzheimer's disease may be linked to aluminum content in the body [Amdur et al. 1991]. Analysis of the aluminum content in the brains of persons dying from Alzheimer's have shown increased levels, although brain aluminum levels vary greatly. A second correlating factor is that neurofibrillary tangles (NFTs) have been identified in both aluminum encephalopathy and in Alzheimer's disease [Amdur et al. 1991]. However, it has been shown that the NFTs produced by the two conditions are structurally and chemically different and that NFTs are present in several other neurological disorders. It appears that the aluminum content of the brain is less an issue relating to exposure to aluminum than an issue of a blood-brain barrier defect or compromise of some kind.

I'm not certain how aluminum being consumed by the mycelia might affect growth, but I can tell you for certain you don't need to worry about negative effects from eating miniscule amounts of it.
