Came upon these roadside clusters of what I would normally just called Crowded White Clitocybe , probably C. dilatata . They had all of the ID features including being clustered , misshapen, white spores and typical elliptical to pip shaped spores. The big difference was that these Clitocybe smelled absolutely terrible almost rancid like, where as C dilatata has a slight to mild odor. It keyed out perfectly as C fasciculata using the Pacific key council keys.
