: I think the real question is why do some seedlings in a community pot die of fungus infection while others getting identical treatment grow into healthy plants? My guess is that the ones that live just chance upon a symbiotic fungus first which invade the tissues and protects from further invasion by pathogens.
Another point may be that some seedlings are more vigorous and less sensitive to pathogenic fungi than other and therefore easier to cultivate. Selecting these seedlings seems an interesting (and perhaps the only) way to bring difficult species into culture (e.g. C.montanum, C.cordigerum).
