My tree ferns get tons of spore, it's not easy to scrape off, but it threw everywhere and set in a tray i had nearby anyway, in the greenhouse. It prefers the cold moist atmosphere there, I had a tray with some in inside, when we started to have the heating on it started to dry so I put a plastic bag over, then the cat tipped it up! Those in the greenhouse are doing well! They are very hardy, possibly Cyathea brownii, not sure of the other one as it's thinner trunked, could be C australis but the fronds are similar on both, I don't know if they alter when older.

I think this is C brownii
