What is this weed? - wild lettuces

Hi,
Here are some photos of a plant growing next to my house near Boston, MA. They are in rocky soil next to a stone foundation. The pictures were taken May 7 and May 12. We've had lots of rain over the past 6 weeks & temperatures have been locked in at 50 F during that time period. Can any of you identify the plant? Is it hawkweed?
Thanks!

Hmm. Dunno.
If no one can help you from these pics, don't give up. When they flower post some more. Sometimes we can help then.

Smart phones have a plant id app. I haven't used it but have been meaning to put it on my phone.

Looks like one of the wild lettuces: http://www.innerpath.com.au/matmed/herbs/Lactuca_virosa.htm

If the leaves have a milky sap and taste bitter they are a type of doc. Otherwise they are probably a wild lettuce.

Certainly looks like Lactuca virosa to me, if the underside of the leaves AREN'T hairy, which they don't seem to be.
Extract the sap through slits in the stem while it is in flower, as an orally ingested pain reliever. I know a fellow that cut up a plastic straw to make a harvesting trough, catching the sap.

That is really interesting, Thanks.

Man, I have that stuff all over here. Will have to look into the 'what can it be used for'? Medicinal not salad uses, I can understand....
