    Hi again. I posted this plant before, it’s an OZ refugee that I got very cheap, it had thrip damage, no live roots, had the postbloom growth and one tender shoot (which promptly succumbed to a white rot, as did one, two, three of the postbloom growth leaves)...but one leaf did survive and I kept hoping...then at last, after 9 months, a nub oc growth! And here is that nub a couple months later. I don’t understand what caused the browning in an otherwise happy-appearing growth and would love to avoid it in the they’re. Nothing else in that wardian case thing has browned or burned. There was some paling-out among other plants in June that I attributed to sun stuff so I did move them around and it promptly reversed, but my understanding of P. philippinense is that it’s a high-light plant anyway. The one mature remaining leaf is succulent like an agave! Blows my mind. Not confident at all with these multiflorals. Advice appreciated. This one is in a Wardisn case with an open top in a southeast window in my Chicago apartment. Thank you all.

    I'd do the same. I'd cut away the old growth, it's last leaf has rot at the base and don't seem to be useful anyway.
    Good luck, a new leaf is on the way!

    This doesn't really look good and in my eyes from what I can see in the photos it's a fungal infection, rot at the leaf base caused by Fusarium or Pythium and Phytophthora rot. Here is a link where you can read more about orchid desases and your problem in particular. Languages are German and English.

    The link shows the overview page. Have a look at Fusarium and Pythium and Phytophthora rot.
    Cut away all rotten parts of the leafs and isolate the plant. Eric mentioned dragonblood as a 'medicin' another one is cinnamon powder. Cinnamon is antifungal. Make a paste of cinnamon powder and destillated water with a drop of dishwashing detergent and apply it on all affected parts of the plant. No guaranty it will survive but some did in my collection. Good luck.
