What about trying to include fungus spores in your propagation project?
At least here in southern Africa there are a few labs that specialize on 'friendly fungus' as biological pesticides and as parts of soil improvement programmes.
It's been mentioned already that you're not just looking for any kind of mycorrhiza, but perhaps there are labs around that have done some work on orchids and can help you?
For my next Eulophia
speciosa project, I'm still going to collect sand from around the bulbs of the mother plant, but I'm also going to add a fungus that we're already using in our commercial vegetable production and that the lab says have had a positive effect on seed germination and early seedling phase.
I don't know if it's going to make a difference, but I'm thinking, what the heck, I'm using easily available seeds and this is a project that costs me a dollar or so. I can afford that, even if it doesn't work.
There is something very fascinating about trying to germinate seeds outside of flasks to me, even though I still think that is the approach that will ensure the highest germination rate and probably also long-term survival.
) that you could have, but they tend to like slightly cooler weather than y'all have, so it may not work there... Could pollinate my P. cornu cervi...
