Mycaureola dilseae here was found on a piece of Dilsea carnosa, Red Rags, as driftweed at Lariggan Rocks, Penzance, Cornwall, 31.08.18.

Lesions are reported as having a maximum diameter of 20mm. The inner part of the lesion is typically white, this is where all the algal photosynthetic pigments have broken down. Out from this there is a 2-4mm greenish zone where the phycobilin pigments have been degraded, this then meets the red uninfected normal tissue.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help
people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
