Fungus RNA isolation

we are using Trizol Reagent for isolation of total RNA from a fungus that 
can be either grown as yeast or as mycelium. RNA extraction from yeast 
cells works well. But when we work with mycelium we get a lower yield and 
multiple bands (degradation?). We follow the standard Trizol protocol 
provided with the reagent. Our tissue is prepared as follows: grown on 
cellophane over solid medium, harvested, ground to powder in liquid 
nitrogen and stored at -80C.

Do you have any suggestions/tricks on how to isolate RNA from mycelium 
using Trizol that could improve quantity and quality of the RNA?

Best wishes,
