This photo was originally submitted under the name Corydalis ochroleuca (and then that species page was moved to Pseudofumaria alba subsp. acaulis). I think the flower shape looks more like Corydalis sempervirens, also known as Capnoides sempervirens (Rock Harlequin (Capnoides sempervirens).

Pseudofumaria has thinner or shorter flowers, and the yellow is only on the inner petals, not on the crested outer (top and bottom) petals. There are also differences in leaf shape and the plant's habit. C. sempervirens is taller, often a few feet high, and the leaves and flowers are spaced farther apart on the stems. Pseudofumaria is a little mound of closely set leaves, at most a foot high.

Usually Corydalis sempervirens is pink with yellow tips, but according to the book Bleeding Hearts, Corydalis, and their relatives, it can also be white with yellow tips. I'm guessing this is the white and yellow form of Corydalis sempervirens.

Jonna, what do you think? The flower shape difference is a bit difficult to judge, but do you know if the plant is higher than a foot (1/3 meter), like S. sempervirens, or if it is a little mound of leaves less than a foot high, like P. alba?

Unfortunately I lost the plant, but I'm sure it was not higher than 8 inch. I also had the pink/yellow C. sempervirens, which is much higher, it was here about 2 feet high.
