RE: Fungus

Hi,

This past summer (Bay area, California) my front yard
suburban garden had an unexpected amount of plant
death.  I lost

Ceanothus hearstiorum
Osteomeles schwerinae
Pelargonium sidoides
Euphorbia characias 'Portugese Velvet'
Cercis reniformis 'Oklahoma'
a Helianthamum, an Erodium and a few others

and this is in a small garden!  After a few showed
dead branches and then died quickly, I began to
suspect something systemic like a fungus.  This
past week after rain, mushrooms emerged.

Are these possibly Armillaria?  Does anyone have
any advice for me?  I have a dry garden with a drip
system that has worked well for 7 years.  None of
the dead plants I dug out were in wet soil.

The Osteomeles in its full glory 2 months before it
died:
