OMLA 2010 Fall Foray
Muskingum County, OH. October 2-3, 2010

The Summer 2010 foray of the Ohio Moss and Lichen Association, organized by Barb Andreas and Ray Showman, was conducted in Muskingum County, in east-central Ohio.  Muskingum County is located in an unglaciated region of the state, underlain by Pennsylvanian bedrock which, having formed during the aptly named Carboniferous Period of the Paleozoic Era, has been the site of extensive strip mining for coal. A wonderful ecological reserve named “The Wilds” is here, and their amazing staff graciously allowed up to stay overnight and work at their lodging and research facilities, and collect on the preserve.

The foray was attended by 17 people, including 2 who arrived later, and so were absent from the group photo.

Collecting began at a woodland and meadow complex at The Wilds that is also an active research site for a team of scientists studying pollination ecology.

A number of cryptogams were seen and identified. One of them is this fruticose lichen with abundant squamules at its base, from which project elongate pointed podetia beset with powdery soredia.

After lunch the group went to a remnant woodland where, at its edge, there was an old abandoned oil storage tank, and this almost surreal relict machinery.

A leafy liverwort seen on a decorticated log is strongly flattened, and has leaves that are emarginate and two-lobed (bidentate).

A large lichen with a loosely adnate gray to brown thallus having a cyanobacterial photobiont was seen growing at the edge of a boulder at ground level.

 This woodland is home to a few interesting angiosperms in fruit, two of which are orchids. Here’s spotted coral-root, Corallorhiza maculata. Coral-root is a saprophyte, entirely devoid of chlorophyll.

…and this is large twayblade, Liparis lilifolia.

In the evening, we settled in to the wonderful The Wilds research station, where we stayed up until the wee hours identifying our myriad finds.

…And by the end of the night amassed quite a list of bryophytes (and lichens too).

The following day we visited Blue Rocks State Park. Here, a rich woods dissected by a shale-banked stream provided especially good moss substrate.

…while better lichen habitats were found on the bark of trees.

One of the mosses is a robust, light green julaceous pleurocarp found on the soil of a steep bank.

 Nearby, a planted non-American chestnut tree, probably Chinese chestnut, Castanea mollissima, was in perfect condition, having just dropped a great number of its spiny fruits with delicous seeds inside. These were avidly gathered by several OMLA members, and were delicious!

Our final stop was the fire tower at Blue Rocks State Park, which afforded a nice view.

A lawn area here was good substrate for at least one bryophyes not seen elsewhere during the foray, a little strand of which was pushed up by this Amanita muscaria mushroom.

Scattered trees here provided good substrate for bryophyes, lichens, bryologists, and lichenologists.

Even man-made structures, such as this wooden picnic table, are colonized by lichens. One of the lichens here is a fruticose one with small sorediate squamules, and podetia also with mealy soredia, tipped with bright red apothecia.

One the way back to civilization, some OMLA members has the pleasure of seeing this delightful sign installed by the U.S. Forest Service.
