Mosses, mines and Male Ferns

I am not a person who generally suffers from Seasonal Affective Disorder (SAD). Even in the darkest months of the year there is usually something in parks, gardens and hedgerows to pique the interest. But having said that this particularJanuary has dragged on summat rotten.


Today I revisited old haunts and took a stroll around Byfield Pocket Park. An adjacent patch of pasture is technically part of the park although of late it has become a dumping ground for piles of cleared vegetation. But an old willow tree stands in this area. As an example of its species it is unremarkable, but it has developed some interesting features. Obvious are the luxurious patches of moss around the base of the trunk, making it a picturesque sight.

From a distance I took a guess that it could be Common Feather Moss, Eurhynchium praelongum. Certainly a tree trunk is a very typical site for this common species. I took a sample and quickly realised I was quite wrong and a closer inspection showed that it was Hypnum andoi.

It proved to be Hypnum andoi, and formed a lovely cushion.


This very common moss is known as Mamillate Plait-moss and its preferred habitat is indeed on wood.


Elsewhere bramble leaves had been mined by the Golden Pigmy Moth, Stigmella aurella. This is by far the most frequently encountered species within an aggregate of very similar species.


Stigmella aurella is an exceedingly common sight on bramble leaves.

Specimens of the Male Fern, Dryopteris filis-mas, are common in the wooded areas of the pocket park and I examined them closely (and without luck) for galls and leaf mines.

The Male Fern is a common species in Byfield Pocket park.

This fern is identified by the sori (reproductive organs) on the back of the fronds which are generally in clusters of about four to six. (Incidentally there is a species known as the Lady Fern, Athyrium filis-femina which is not quite as common in the county)

I have had more exciting and productive visits to the site but I was cheered by noticing, just as I was leaving, that clumps of daffodils are close to flowering. They aren't great for attracting wildlife but they were good to see.
