I know i've come in a bit late with this but the first one "Moon Beer" looks like "Flor" yeast, the same stuff that they use for concentrating sherry. it probably would have been OK if you bottled it as i don't think it would have contributed to the flavour.
i have also had this from a batch of coopers yeast which i put into a starter as an experiement to test taste and flocculency of different yeasts. all the other yeasts were fine in the experiement, so it may not have been your fault, it still tasted fine and was at normal gravity at the end.
This yeast will only grow like that in a oxygen environment, i'd be checking on the seal of your fermenter or try using glad wrap and the rubber ring from the lid to seal, i've found this works well can you can check on whats going on. One of my fermenter has a leek/seal problem and it makes it hard to know if things are happening as the air lock only operates when the yeast is in full swing then stops as things slow down.
P.S. get some starsan or saniclean or other no-rinse sanitiser, put it in a squirt bottle, use liberally on anything that goes near your brew!
