very impressive photos. How come all the pretty rusts are found in other people’s part of the world! The telial stage is less spectacular macroscopically, but the spores are rather splendid . . .

Believe it or not, the above (rather dire) image, shows the same type of spores that can bee seen in Chris’s excellent composite image in the previous post.😳 – And yes, they do look so much better by eye, than my Minicam’s limited megapixels are able to resolve.Regards,
