The way to have fungi present in vermicompost [VC] is to feed the worms carbon based ingredients way before you harvest the VC or consider using it in ACT. (cardboard, woody debris, sphagnum peatmoss, etc.)
Sorry to disappoint but the fungi you grow by adding oat or other flour to finished VC is most likely the same fungi you get by keeping bread for too long.
IMO, no amount of trickery or special recipes will make the correct types of fungi magically grow in finished VC. It has to grow/evolve over time,
BTW the recipes for this call for flour, not cooked oatmeal, which likely accounts for the wicked smells. I do use wheat bran to pre-feed VC sometimes 24 hours ahead of making ACT.
"and moistening with very diluted black strap molasses, loosely covered with cloth or paper towel 24 hours ahead of brew. (approximate ratios, wheat bran 1:30 [vermi]compost & BSM 1:300 water).
This has, so far resulted in (most of the time) attaining the desired microbial population at 24 hours brew time rather than the usual 36 to 42 hours."
Anybody can be wrong about anything.
