Another "lost structure" is linin, which at the end of the 19th and 
roughly the first third of the 20th century was supposed to be an 
acromatic scaffold in the cell nucleus in which chromatin was embedded. 
I never figured out if what was described as linin was just widespread 
imagination/artifact or if it relates to a "modern" structure. It 
appears the term simply faded away in later decades.

In some aspects linin seems to have been a predecessor of the nuclear 
matrix - another term that seems to fade away over the years (but maybe 
I am having a wrong impression on this one)

Mesosomes are an example of an EM artifact in bacteria that "existed" in 
the 1960ies and 70ies, see https://en.wikipedia.org/wiki/Mesosome
