Pete,

I haven't heard of Artillery Fungus here in NSW Australia but I think our restrictive firearms laws would probably mean it'd be illegal to posses, LOL.

As to mould spores in general, my experience had been to suffer symptoms similar to Legionnaire's Disease until I took to wearing a mask. (Not just when handling woodchips but also when having to do any digging.)

I had five very large truckloads of woodchips delivered from the Air Force base where I work just as my haematologist stopped me from working in the garden until my bloods were improved. (Decreased immune system due to chemotherapy for Leukemia.)
That has gone well and I am now back gardening, (with a mask of course,) however my five truckloads of woodchips have decomposed into a very good soil additive for my raised garden beds. Wish I could get another five truckloads.
On second thoughts, make that fifty truckloads!

Cheers,

Bid
