Re:  your request for means to disassemble a virus of mushrooms that 
will separate but not degrade the capsomeres.

It is possible with some plant viruses to nudge the capsomeres apart 
without destroying them, using a combination of pH stress and solvent 
polarity stress.   J. S. Semancik and J. B. Bancroft published such a 
method in 1965 (Stability differences between the nucleoprotein 
components of bean pod mottle virus, Virology, Volume 27, pages 
476-483).  They exposed the virions to chloroform at pH between 9 and 
10.  I used their approach in my MS thesis research (1971) at the 
University of Arkansas in Fayetteville (Effects of organic solvents and 
alkalinity on components of two isolates of bean pod mottle virus).
