Dear Alistair

: Species such as Verticillium dahliae demonstrate rather species specific toxins, though others, such as V. albo-atrum, have wider host ranges. Did they detail the species isolated, or was it not identified at that level?

I have had chance to check the lab report which said:-

“Two fungal pathogens have been found sporulating abundantly on the incubated material and they have been issolated from the affected part of the crown.

Verticillium albo-atrum which is responsible for a wilt on a number of hosts but we can find no record of it causing disease on an orchid. On the other hand Botrytis cinerea is very common and therefore more likely to be the cause.”

Best wishes
