They are tough to find sometimes! The equivalent chemical test (most red species are also KC+ gold) is also equally difficult to interpret in my experience. Sometimes you just need patience and luck.

I saw red pycnidia with a hand lens.

It seems to me that this is a matter of perspective of the pictures: what’s good for the photographs in this case is not good for the details. I upload a (bad) photo which allows to notice the red dots.

not sure of red pycnidia

I can’t find any red dots at the ends of the stalks in your photos. But they can be hard to find in C. macilenta, and it does otherwise look possible. But I would also consider one of the brown-tipped ones like C. ramulosa or C. cylindrica (yours is probably too large for C. cylindrica, though). To be sure you’ll have to either look very carefully with a hand lens and find some red dots, or do the chemical test (drop of KOH followed by drop of bleach).
