Seaweed like green plant was created by Barry C
At the recent AGM night, some people mentioned seeing a green seaweed like plant growing on a few paths and drives in the village. On looking closely at the plant, it looks like it is a liverwort; and is similar to one called Pellia. Winter is not the best time to try and identify liverworts, because most of the diagnostic features, the reproductive structures, are absent at this time of year! Liverworts are a very ancient group of plants which are related to the mosses. Liverworts have been around for about 470 million years, more than 200 million years before the dinosaurs!

Thanks Barry for identifying the green monster plant.
Whilst I understand it has been around for 470 million years it seems new around here?
Which raises the questions, what environmental conditions have let to it multiplying and is it a threat to anything?

Another new site has been found by Cathy, on the bridge at Southfield. It could have been growing here unnoticed and much less extensive for ages. It is spread by spores which are very small on the wind. It would be a surprise it appeared this year in all the four sites, all in the same year.
As for a change in environmental conditions that could have favoured the luxuriant growth, it could be the wet weather, keeping the humidity levels high. The normal site is on stream banks or in a humid site, so a wet year in a shady area could suit it.
