Ards revisited

As you will know, Ards has become a favourite place for me: the ancient forest with clean, western air is a wonderful resource for anyone who wants to find real treasures. I hoped to find fungi, but we can never be sure what we will find, given their ethereal nature.

From the outset it was clear that the recent cold weather had reduced the numbers of large mushrooms, but there is always plenty to see if you become sensitive to the smaller 'stuff', so I switched my attention to smaller things.

First is a species of Collybia that I have only seen a few times: Collybia aquosa. This is distinguished by its bulbous stipe. Cap is 25mm diameter.

When I got the photographs back to the study, I had a closer look at the beastie on the gills and found this:

Psocid on Collybia
It appears to be a Psocid, or 'bark fly'. These are from a family of insects that eat bark in wild situations, but have become partial to paper in domestic situations, especially with regard to books.

Fungi and mosses are tightly associated: both like damp and darkness. This is Plagiothecium undulatum, which is very readily identified by the almost fish-like appearance of the shoots.

Plagiothecium undulatum
Mosses are very difficult to identify at first encounter, but once the relevant identification steps have been taken (microscopic analysis is essential), they are readily identifiable in situ. One of the identification features is 'leaflets mostly curving in one direction'. This feature is easily identifiable in the field, but less easy to show in a photograph:

Dicranum majus moss

This portrait shows the feature more clearly:

I found this minute Waxcap specimen, and although it's far too young to identify, I'd make a decent stab at the Blackening Waxcap, Hygrocybe nigricans, which will turn orange, then red, then black:

Juvenile waxcap
Myxomycetes, or 'Slime moulds' have always been seen as part of the fungal family, but recent research has begun to associate them more with amoeba. They are certainly mobile, and they react to light.

Slime mould
They reproduce by spores and decompose vegetable material, but their mobility and reaction to light make them seem more like animals. These fruitbodies are about 1mm in diameter:

Perhaps a Trichia sp.

On the way back to the car I spotted this grassland Panaeolus sp.:

Mosses, lichens and liverworts, oh my!

Original Hedgerow, leg 1, whilst on a film shoot. One of the things I have to do when on these shoots is 'pretend to be taking a photograph'. What better way to pretend than actually taking shots?

This first shot - on a wall - shows a lichen (Cladonia pyxidata, pale green, centre with pink, embryonic fruitbodies), at least three mosses:Bryum capillare (olive-brown rosettes dotted around the image), Homalothecium sericium (silver-tipped shoot, left of centre), and an unidentified specimen with curled leaves (right edge).


This shot shows the liverwort Lunularia cruciata, with its diagnostic moon-shaped gemmae cups, with gemmae (little bundles of cells that develop into new specimens) spilling out.

This could potentially be a very confusing shot. The central 'specimen' is in fact two mosses. The pale grey cushion in the foreground is Grimmia pulvinata, and the capsules and setae at the rear belong to a specimen of Tortula muralis, which is hidden behind the Grimmia.This is a moss: Plagiothecium undulatum. I find it very reminiscent of a minute fern.

This moss forms 'boots' around all the trees and bushes around here: Hypnum cupressiforme.


It was raining, so I got a couple of water-droplet-shots. The large droplet to the left is on the capsule of Bryum capillare, and the smaller droplet to the right is on Tortula muralis.


Here's the Bryum capsule in closeup:
