What causes a cottony looking fungus to develop on top of the potting mix? Too wet, not enough air?

most likely a little to wet ...but I have saw times when it was just the right conditions even if it was not realy "to wet"....a good fungicide would help.

What fungicide do you recommend?

Physan 20 is recommended a lot by others on the ob ...I myself got some a couple of months ago and it has helped my fungal issues

I know that some have used Thiomyl, Physan 20, regular cinnamon and just any alcohol that happens to be in the cupboard! I use Listerine, but I'm sure you'll find something that works for you.

Thanks to all. I have both the alcohol and listerine. I'll try them while looking for the Physan 20

Physan 20 can be bought through Amazon.com ....I got a small bottle for $20.It dosent sound like much by at 2 teaspoons per gallon that bottle is going to last a long time with my small collection.

Thanks. Hope it doesn't go stale, looks like I'll have a lot on hand also.

question... so when I have a skewer inside a phal pot of bark, and I remove it and it has little mold spores on the skewer, is this when I should be applying Physan 20 or listerine, etc?

I have yet to purchase Physan, but I have 97 plants, so I really should just cross that off my list as well
