Liverwort solved

On 5th February I showed Conocephalum conicum growing over the top of another, smaller, liverwort. After some microscopy I have now identifed the small liverwort as Pellia epiphylla. Here's a closer shot:

Sample shown is about 6 cm. across. (Note the female reproductive structure to the extreme right, just above centre:)

Here's one of the photomicrographs that I took as part of the identification process. It shows a darker area to the left which is actually a thickening along the midrib:

Magnification is x 40.
