Artillery Spores. What is it?

[Steven Carpenter]

The word "mold" is a common term used in various ways:

1. Least precise: applied to any state of a fungus that is not
    recognizable to the viewer as a "mushroom"

2. With more meaning: applied to the non-sexual sporulating stage
    of the life-cycle of a fungus


All molds are fungi.  

Therefore the artillery spores are fungi.  They are also a mold. 
Without knowning more about your source for the term "artillery spore",
I will assume the term refers to the genus Pilobolus.
