200X Ok?

I just got a microscope, old-school friggin tank... weighs like 25lbs. I think the objective is 10X, then the lenses are 4, 10, and 20. I looked at what I believe to be g. ventricosus spores, and @ 200X could definitely see them, but they take up like 1/20th of the field of vision. The resolution is *nice*! I read that they are "warty", but can't see these "warts". Do I need another lense for positive id?
thanks in advance.

Damn, 64 views and no answer. Did I ask something stupid?

200X should be alright for looking at spores. I usually use 400 or 1000X. I would suggest getting a 20X objective for your scope. They can often be had reasonably on ebay.
As far as your question about the spores being "warty", I have no idea. One key entry I pulled up lists them as "7.5-9 x 4-5.5 µ, ellipsoid, ovoid or almost almond shaped in face view, verruculose, no germ pore, slowly dextrinoid."
"verrucose: (1) with the surface ornamented by small rounded processes or 'warts' (Nag Raj, 1993); (2) distinctly and regularly rough-walled (de Hoog & Guarro, 1995)."
So it looks like they are indeed "warty". Hope this helps.

STIPE 14-18 cm long, 20-30 mm thick, pale brownish, yellow-fibrillose to subglabrous, densely white fibrillose at apex, solid, distinctly ventricose. VEIL forming almost apical annulus. MICROSTRUCTURES spores 7.5-9 x 4-5.5 µ, ellipsoid, ovoid or almost almond shaped in face view, verruculose, no germ pore, slowly dextrinoid. Pleuro- and cheilocystidia. Pileus trama interwoven.
