Sometimes just grey smears too.
Easily seen when lens is off the camera and look
from the camera end. If that test is OK, then say
to the ebay buyer guy "no visible fungus" or some such.
I have a simple 50 year old spotting scope which was
thick with it, even between two lens that were in contact
- took the thing apart (it was very simple
design) and cleaned with glass cleaner and its come
up amazingly well - works fine as a second scope when
out with two people.
On a modern complicated lens, as Wilf says, will cost
a bomb to disassamble and clean.
