Favouring histoplasmosis over leishmaniasis due to the size of the organisms and the surrounding individual clear haloes, will ask for PAS and Giemsa.

I think these spores are quite large and clear haloes very conspicuous, sometimes fused, more consistent with cryptococcosis.

Will go with cryptococcosis. Spores are larger than histoplasmosis or LD bodies of leishmania. Also they are spaced apart due to their capsules and there appears to be a mucoid b/g. Mucicarmine or Alcian blue along with pas and giemsa needed.
