TLDR
The fungus Aspergillus flavus when challenged with a silver nitrate solution accumulated silver nanoparticles on the surface of its cell wall in 72h as discussed by the authors, and these nanoparticles dislodged by ultrasonication showed an absorption peak at 420 nm in UV-visible spectrum corresponding to the plasmon resonance of silver.About:

Extracellular biosynthesis of silver nanoparticles using the fungus Fusarium oxysporum
Absar Ahmad,Priyabrata Mukherjee,Satyajyoti Senapati,Deendayal Mandal,M. Islam Khan,Rajiv Kumar,Murali Sastry +6 more
TL;DR: It is observed that aqueous silver ions when exposed to the fungus Fusarium oxysporum are reduced in solution, thereby leading to the formation of an extremely stable silver hydrosol, creating the possibility of developing a rational, fungal-based method for the synthesis of nanomaterials over a range of chemical compositions, which is currently not possible by other microbe-based methods.
