Asterochloris algea is the primary photobiont algea for Cladonia sp lichens. I found this algea in a Cladonia, therefore it is probably Asterochloris sp.
Here it is at x2000 magnification.

Collected from B.B. Clark Beach on Lake Monona, 7/9/2024. Along the edge of the water during a slight algal bloom.
