    Lily, that's not crown rot. It's just some dead tissue that surrounded the spike when it first started to grow, and is now unnecessary. No worries...

    Agreed. Just some dried up tissue. You see the same stuff with old cattleya spikes--it's like those sheath-like coverings on the pseudobulb, but up at the spike. Dries out, harmless. True "dry rots" are very rare--a fungus whose name eludes me can cause a devastating systemic infection. But this ain't it.

    Thanks for your help !

    I was worrying a lot but now I feel fine .

    The "rot" a.k.a. dead tissue seemed suspicious because the two smaller leaves at the tip just yellowed and fell off. I thought it had a horrible rot problem with leaves falling off, but hearing from you guys, I guess it's just a natural cycle . small little thing on my orchids and I'll freak out...

I've always been careful not dropping any water on to the crown, but you know, mistakes may have gone on unnoticed.

    So today I scraped a little off, and and the tissue is all dried-up brown and goes away in tiny's dry rot....I don't know how deep it is. This is crown rot, right? I would like to know how severe the case is, can it be cured (at least stop it from continuing to eat up my poor dend), and if so, how I can control it. The plant is otherwise healthy. Please check the photos I attached.

    Thank you,
    That doesn't look like rot to me, and I have had a couple of really rotten dens. The cane turns dark brown and squishy and if you do get the guts to squish it, it oozes purple/ brown smut. Sorry it sounds gross, but it is the best I can describe. It looks to me like possibly callus? (Louis, tell me what you think on my opinion here).
