    Hi,

    This is my plant:
    [1]
    [2]

    From what I googled, seems like it's a dracaena trifasciata (snake plant), is that correct?

    As you can see, I cut some holes in it, because it looked like it was infected and probably spreading. Here are the slices:
    [3]
    [4]

    I made transverse sections near the "infected" area and looked at it through a microscope:
    80x
    200x
    800x

    I'm don't know much about plants or fungi, but is that fungal infection?

    Thanks,

    I'm not the person to answer your question about your plant's issue, but yes, it's Dracaena trifasciata, which maybe even all of us know as Sansevieria trifasciata, though the name seems to have changed in 2017.
    It would be easier for people if you would post your photos directly here. You can have a look at Attach photos and files and post them in a reply.
    You're keeping this indoors, is that right?

    No problem.

    Here are the photos of the plant:

    The slices:

    The microscope images:

    It's on the balcony, exposed to direct sunlight and open air.

    I think @Frog may have the most experience with microscope work and fungi here.

    In that last shot I see what looks like fungal structures but not certain. There are also a few variables to be aware of: If a fungus is growing on those spots, it may have caused them or it may be taking advantage of a vulnerability caused by something else (or consuming already dead tissue).
    I think it might be better to approach this from the list of known diseases for plants of this type (fungal, viral and other), and compare the symptoms. Just a suggestion - am not a plant pathologist.
