Jeff, You`re not doing anything wrong. The growth of mold is random at best. Different areas are known to produce species of their own and are even famous for their unique cultures. For instance, the Roquefort-sur-Soulzon caves of Mont Combalou in southern France contain soil producing the unique flavor of the mold Penicillium roqueforti.
In making sausage, we have to remember to use ONLY the white, fluffy stuff. These are the penicillium nagliovense and penicillium chrysogenum genus. Penicillium is a genus of ascomyetous fungi. Members of this genus produce penicillin - a molecule that is used as an antibiotic which kills or stops the growth of certain kinds of bacteria inside the body. The penicillium genus contains over 300 species according to a 2008 medical publication. Of these 300 species, only penicillium nagliovense or penicillium chrysogenum are recommended (having the ideal properties)for home sausage production in a dry-cured meat product, although I`ve known a few people in Europe to use the cheesemaker`s favorites - penicillium roqueforti and penicillium camemberti, on meat. With penicillium nagliovense and penicillium chrysogenum at our disposal and readily found on the market (Bactoferm™ is found in most sausage supplier`s catalogs) relatively cheaply, I do not understand why someone would want to cut corners financially by growing their own cultures by using the penicillium roqueforti and camemberti cultures (developed especially for cheese) from leftover cheese products.
Biologists use "spp." as a short way of saying that something applies to many species within a genus, but do not wish to say that it applies to all species within that genus. Note that spp. = species (plural) and sp.= specie (singular). If scientists mean that something applies to all species within a genus, they use the genus name without the specific epithet.
So, using a white "naturally grown" indigenous mold is usually safe. The ones to watch for are molds of any color. If you spot darker molds or fuzzy molds of green, black, etc., get rid of it. The good ol` white penicillium will usually crowd out the toxic mold, but not always. Good luck to both you and SausageJohn with your projects. They are looking great.
Best Wishes,

If it looks like a duck, walks like a duck, and quacks like a duck, it probably needs more time on the grill!
