mossy 的鑑定

Hiked around in the Evergreen woods with the MES students today and came across this. Shaggy cap and it was still closed. Found on the ground near western hemlock (Tsuga heterophylla) and big leaf maple (Acer macrophyllm). Sorry my photos are not great of this.

I observed this moss at approximately 17:00 in the woods behind where I live. The temperature was about 55 degrees Fahrenheit and sunny. The plant is growing epiphytically on a young big leaf maple (Acer macrophyllum) or red alder (Alnus rubra). Plant is is a green cushion.

This specimen was observed on Thursday, February 23 2012 at around 13:00 on the Evergreen State College Beach Trail. This moss was found growing in clusters on several fallen branches. Appears to have an almost cushion life form, with the long stems radiating from a central point. Leaves spreading when wet, and highly appressed to the stem when dry.

I found this moss clinging to an apple tree that had fallen down under the weight of the snow. The moss was part of a large west- facing mat on the tree trunk. The moss is pleurocarp.Using my hand lens I can see the sharp tips of the leaves and the many branches coming off the stem, the leaves are all yellow green in color. Just keyed out under the scope, but would like to bounce the ID I came up with off others. Thanks

Look at this beautiful specimen! Found this lovely moss on a Douglas fir tree stump. The leaves are on average 1mm in length, and are fairly spaced out on the stem.There were no sporophytes present on any of the moss in this location, any thoughts on the ID?

Arrived at this site at approximately 0800 hours. The weather was overcast with occasional showers with an air temperature of 37 degrees Fahrenheit. The site is located in a mixed Douglas fir and Hemlock stand forest. The soil is of a humus type and is in a rather moist area. The site is on a medium incline on a northern aspect.
The specimen taken for analysis and identification is Plagiothecium undulatum and was on a fallen tree. The plants are large, whitish green to pale green, with a conspicuously flattened appearance forming mats in shaded areas. Leaves are 1.5 to 4 mm long, narrowly egg shaped to lanceolate and sharply pointed. Sporophytes are common from the side of the stem with long inclined capsules that are smooth and curved.

I had never seen moss like this before. Each individual frond is like a fern-hence, fern moss. A book cites it as Hylocomium splendens. However, it could be something completely different, although a type of moss. I posted two different kinds of fern moss in the two pictures, both found along the trail and on the forest floor.

Weather was very sunny with no clouds and not much wind.

Found on a Pseudotsuga menziesii near the base in a northwest facing direction. In a second growth forest about 5m from the stream. Overstory mainly Pseudotsuga menziesii, Acer macrophyllum, and Thuja plicata. The understory consisted of Acer circinatum, Gaultheria shallon, and Mahonia nervosa

The Evergreen State College beach trail woods, off the beaten path. At dusk, 50 degrees F. Noticed a neat little patch of P. undulatum which caught my eye with its bright green branches drooping individually. Sporophytes present. This patch was consuming the entirety of the bottom of a large stump. Very little vascular vegetation present, within a compact Thuja Plicata and Alnus rubra woodland, no other trees present. Next to a small creek. In the distance we could hear the calls of 2 or 3 very loud owls exchanging calls for a number of minutes.
