Pacific northwest gardening black mondo grass disease? and fungus/moss id?

Hi- I have few questions/concerns regarding my garden, and hoping to get some expert opinions!

The first is in regards to black mondo grass. My mondo grass appears to have some sort of disease or fungus- each little strap has brownish white spots all over it. Also, something appears to be eating it but I cant quite tell so don't know how to proceed getting these plants to look healthy again. any ideas or knowledge would be much appreciated!

My second question is this strange moss/fungus? I really dont know what it is that has been spreading all over my soil and am worried it is effecting the health of my plants. It occurs mostly in more shaded areas but even spreads into sunnier locations. It started out small and now is covering a huge portion of my front yard. Does anyone know what this is? Is it damaging to plants? How do I get rid of it?

Thanks you in advance!

 

Not sure what is going on with the mondo grass. Possibly small marks left by insect damage?

The second plant is a liverwort. This indicates a very moist garden. I get them on the soil of my potted plants sometimes. They can be a problem.
