describes the cap as honey colored and smooth and the stem as having a pointed or tapered base. See http://botit.botany.wisc.edu/toms_fungi/armkey.html#mellea

of belaboring the obvious, this does not look like Armillaria mellea.

Armillaria mellea is common in most regions of the state dominated by development, such as the Central Valley, the San Francisco Bay area, and Los Angeles.”

Do you have another name for this?

This is a common species in Southern California that causes a huge amount of damage to over watered live oaks and many other trees in the Southern California gardens. My understanding from Tom Volk is that the material from urban Southern California that he tested was mated with classic Armillaria mellea (although somewhat unusually) so a new species was not created.
