How do you tell your Prof that a part of her class is a total mess?

Online class, mid-semester, prof wants feedback.   
A section of her class is an online group project and it's a total disaster.   
She doesn't oversee any of the work.   
1/4 of the group has literally done nothing but turn in the work everyone else did, 1/2 just says "yeah" and "I agree", the final 1/4 works but can't agree on anything and most wait until the very last minute to do anything, leaving everyone scrambling on Sunday night to try to figure out work that was assigned weeks prior. We've had 3 due dates so far and despite the weeks worth of time we have to do it 1-3 people participate prior to the day it is due and prof hasn't stepped in at all.   
Some members of our group don't understand concepts they should have known 3 pre-req. classes prior and it has now fallen on the few working members of the group to try and teach them remedial information.   
The project is set up where the first 1/2 is group work and the second 1/2 is individual work. Together is counts for 1/3 of our total grade. At this point, I'm fairly sure my group's lazy work is setting me up to lose lots of points on my individual work because they've failed to complete the work the right way.   
I cannot figure out why on earth the prof is letting this go on without saying a single word or helping at all!   
I've stressed and cried about this stupid assignment too much.   
There are 1000 reasons I need an A in the class, but mostly, I shouldn't have to take a lower grade based on the work of others.   
Without any sort of communication or clarification on this assignment (yes I've reached out to her multipul times) I have no idea how my grade will work out.   


How do I tell my professor "anonymously" that this project has been awful?   
She previously asked us to explain the project back to her so she would know if she needed to change the wording of the original assignment. That makes me think this is a new thing she is trying.   


I don't want to come off like I'm being rude or telling her she isn't doing a good enough job, but I don't really know a delicate way to say all this in a way that won't risk offending her.

Try to explain to her, in the most objective and non-accusing way possible, how you have experienced the project thus far. This way, she can get a good idea of what is happening among the students. Leave out words such as 'awful'. 

Furthermore, she has the right to try out a new type of project/assignment and will most likely take constructive feedback into account. You can tell her that you are worried about your grade, as long as you do not attack her. 

It can be very difficult to predict how students act during group work and it is very possible she has no idea what is going on if students do not inform her.
