|My Sansevieria has a scattering of small, raised dry whitish spots. The plant was already in a bad condition when I bought it, and I only did so to try to propagate it, but a new shoot seems to have had a couple of small, transparent raised spots that I scraped off.What could it be? If it is a fungus, what could I use against it? Photos attached.
The one on the left is the old stem, the one on the right is the new one with the white bits at the top.

|Arm yourself with a magnifying glass and look for pests: those look like lesions caused by spider mites. They are tiny critters that can wreck havoc if left unchecked. If you see them crawling about wipe the leaves clean with rubbing alchol or, given the present scarcity of those medical supplies, plenty of soapy water and then dry them.
The Snake plant can be affected by fungi, but usually by Southern blight (which you usually start noticing when it's too late since it forst affects the roots) and red leaf spot which looks like, well, a sunken red spot on the leaves.
Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.

| I don't see anything of consequence on your plant. If the white specks wipe off, do so and that will probably be the end of it. Snake plants are very pest resistant and not at all appetizing to spider mites. There is no fungus problem. I think your plant is fine.
