I don't know what a "slime filament" looks like so I had to use a Key other than the Madrono Doyle and Stotler key. I really wish I had a better key for this area.
I used my British field guide to ID this as endiviifolia based on the teeth on the perianth mouth. The guide even had a drawing of teeth on a perianth mouth to make it simple.
When I colleced this I noticed that it seemed more frilly than P. neesiana and I thought it might be a different species or even genus.
The second picture shows elators and spores.
I'm sure this is a Riccardia but I'm not sure about the species. There were some oil bodies, it's not bipinatly branched it's more palmate but maybe it's just variable.
This was on a rotting log and was mixed in with a tiny leafyliver wort.
One the cells I measued was 75um at the longest and shaped like pentagon.
It's confusing so I'm going with multifida due to the color of it and it looking the most like the picture in my British Bryological Society book.
The first picture is a panorama of 11 photos at 40 times magnification.
Metzgeriales is an order of liverworts. The group is sometimes called the simple thalloid liverworts: "thalloid" because the members lack structures resembling stems or leaves, and "simple" because their tissues are thin and relatively undifferentiated. All species in the order have a small gametophyte stage and a smaller, relatively short-lived, spore-bearing stage. Although these plants are almost entirely restricted to regions with high humidity or readily available moisture, the group as a whole is widely distributed,...
