Well, you could do one of those, or just append a flattened sphere onto the end
of the cone.
You could also go with:

or

or an isosurface with non-linear scaling
(like I did with the vortex)
http://www.econym.demon.co.uk/isotut/substitute.htm
or something like what I did here:

The key with any of those would be that you'd have to define a base object
(likely at the y-axis pole) and then _rotate_ that into position.
IIRC, the "spikes" are trimers, and then there are some kind of smaller pentamer
pores on the surface of the protein capsule.
