I suspect the species seen here is a fungus although rather sadly I did not follow it up microscopically at the time. At the time of finding this I wasn't aware of such things as marine fungi.
Species found in middleshore pool at Spit Point, Par, near St. Austell, Cornwall. 27.06.10. Species was also found on Saw wrack, Fucus serratus.
APHOTOFUNGI supports open source data recording and sharing for the benefit of wildlife, recorders, research, science and education. The project works closely with the following bodies and organisations.
The CISFBR or Cornwall and Isles of Scilly Federation of Biological Recorders is an independent umbrella organisation supporting independent recorders and recording groups in the county of Cornwall.
The Cornish Biodiversity Network or CBN is the largest open source wildlife database in Cornwall that sends open source data to the NBN (National Biodiversity Network). It is a new recording system based on the ERICA database, the largest recording resource in Cornwall. The CBN best supports the activities and needs of the independent recording community and recording groups in Cornwall.
The National Biodiversity Network or NBN is a charity that supports open source data sharing and recording supporting conservation, science and education.
"Why do recorders need open source?". Simply because it supports the core values of wildlife recording and the free use of records and data over a very wide network that includes partners like the Natural History Museum.
