My girlfriend sent me a picture of a mushroom growing in her front yard
in San Marcos, CA. 
I think it is Helvella lacunosa as it has a convoluted, thin, black cap
and a white corded stipe. It tried to attach a picture, but apparently
this contravenes the group charter --

My references claim that H.lacunosa are edible, but one should use care,
parboil them first,
and eat only a small amount as they contain monomethylhydrazine. Are
they worth the risk?
