It's hard to tell from the pictures but maybe Bird's Nest fungi? If so it doesn't hurt anything.

What a pain but you can remove them and rake and spray soapy water to prevent over growth....called Bird's Nest Fungus....

We had it tooNEW by: Anonymous
Had these grow in our garden soil last year around tomatoes and bell peppers, eventually the whole planter. Now not even weeds grow in there! I cant find any information either.

Did you ever find out what this pod like things were? Did you also have tiny black objects (don"t know if it is a insect or what) all over your tomato plants?
