Cursory review suggests that there are pigments in the spores. No information as to why or whether their interaction with light is evolutionarily conserved. However definitely not photosynthesis.

Fungi don't photosynthesize based on modern taxonomy. Green fungi might be mimicking environment / avoiding predators, or eating something that makes them green. OR they might be clear and have photosynthetic orgs (algae, cyanobacteria) incorporated somehow
