natane's Identifications

This specimen was collected from the glacial heritage preserve near Littlerock Washington at approximately 1130 hrs.
This bryophyte forms wooly mats, yellow green upon drying with several side branches. Leaves end in a short bristle tip; papillose leaf cells. This life forms forms extensive mats along roadsides, on roofs, and in open exposed areas.

This pretty Dicranum grows on a Douglas-fir stump in my yard. I finally got around to dissecting it this week and now know that its species is scoparium.

It grows at the base of the stump in the shade of two houses an ornamental spruce and two huge camellia bushes.

This grows on my car and it is smaller than most Bryum argenteum but I belive my ID is correct. I believe it is slightly stunted due to disturbances in the boundary layer created by going to the freeway at 75MPH.

This moss can only grow as high and the plastic bra on the hood of my car. The bra provides a nice niche for moss by giving it a place to hold on, giving it some shade and breaking up the boundary layer.

It also probably helps that this car is mostly parked in the shade on the North side of a house in a river valley where a beautiful temperate rainforest probably used to grow.

If I assume that this moss grew on my car before I bought it, my car has enabled this moss to potential spread west to Neah Bay, Wa, east to Albany NY, North to Spokane and South to somewhere in Texas.

Hmmm.. this moss really has not been very far north.

Thallus liverwort with crescent shaped gemmae receptacles.
On Sunday, I went into the ravine next to my house in OIympia, in search of thallus liverworts. The ravine is steep and after significant snow, the water is running fast. I found these little guys in abundance as I continued to move down stream. They were found on saturated sandy soil amongst the leaf litter.

We found this growing on the ground among leaf litter. There is a disagreement whether it is a moss or a vascular plant.
It kind of looks like a plagiothecium, but bigger. There does seem to be a root, though its short, so could be a rhizoid. It's stem is thick, with a clear costa/midrib visible to the naked eye. Leaves are thicker and longer than most mosses.

I vote on the side of vascular plant, but my colleague disagrees.

What do you think?

I found several Liverworts at Devil's Lake. This Liverwort I thought was Scapania. It was on a rotten log firmly attached to the bark. Under the scope it had dentate leaf margin and an underlobe. Many mosses and liverworts grew intertwined here. The leaf pattern was imbricate.The branching pattern was also pinnate.

Seen on Saturday, 28 January 2012 at around 12:00. Found on a fallen tree limb down in a ravine near running water. It was an open-lit coniferous forest with a lot of vegetation. This particular cluster of Porella was growing with what I identified as Hylocomiadelphus triquetrus. I came to the conclusion that this liverwort is Porella navicularis due to the green color, the presence of underleaves, and lateral leaves that are bilobed with the lobule on the ventral side.

The Evergreen State College. This moss was growing under a Doug Fir tree in leaf litter. It was short individuals growing upright out of the soil. The leaves were about 4 mm long and were red at the ends. Lamellae was seen under the microscope during a cross section of the leaf.
