I know of the decine of the boreal toad, but I don't think it has been conclusively attributed to Chytrid. A quote from the above article:

"Along the coast of Alaska, boreal toads—Alaska’s only toad species—have gone from abundant to almost non-existent in less than ten years. The cause remains uncertain, but biologists have found boreal toads in southeast Alaska and in other states that died from the chytrid fungus."

There have been so many drastic changes in Alaska ecosystems due to climate change, and amphibians are very poorly studied up here. Chytrid may have only been a contributer with other causes more pronounced.
