OMLA 2010 Summer Foray
Henry and Putnam Counties, OH. June 19, 2010
The Summer 2010 foray of the Ohio Moss and Lichen Association, organized by Jim Toppin and Janet Traub, was conducted at three locations in Henry County. Simultaneously, OMLA members Bill and Carole Schumacher explored locations in adjacent Putnam County. These areas are located in northwestern Ohio. Henry County is in the greater Oak Openings region and includes portions of the Maumee State Forest. Otherwise, the counties are predominantly agricultural.
The pre-foray moss records for these counties were quite sparse, with only 11 species known from Henry, and 12 from Putnam. The lichen flora is more well documented, with 15 species for Henry, and 34 species for Putnam.
The foray was attended by 10 people, including 2 who explored Putnam County, and so were absent from the group photo.

Collecting began at a former muck farm along Henry Co. Twp. Rd. 2 in Washington Township that is reverting to an interesting wild state. Here’s an aerial photo view.

…and here’s what it looks on the ground (and in color):

The soil seems to be an interesting mixture of wet, calcareous, organic, and sandy: a quite unique habitat that is home to some intriguing vascular plants with a fidelity to such peculiar areas. Here’s one of them, Kalm’s St. Johnswort, Hypericum kalmianum (Clusiaceae) a remarkably large-flowered member of the genus, and one our very few woody Hypericum species.

Another unusual plant that is found either in moist or dry, usually sandy soil is colic-root Aletris farinosa (Liliaceae).

We carefully scoured all the pertinent substrates. In the photo below, note both the dense herb cover of the open area, and in the background, a dense thicket dominated, unfortunately, by the invasive small tree, evil buckthorn, Rhamnus frangula (Rhamnaceae).

Some mosses were noted to be particularly abundant both in hummocks of the muck farm, and in the thicket. Below, see a moss that is an acrocarp (cushion moss) with very narrow leaves, many of which are swept to one side (secund). The sporophytes have rather long setae, and are topped by an elongate capsule (sporangium). The plants in the photo have immature sporophytes, as evidenced by the presence of a hat-like calyptra, a remnant of the gamteophyte to which the sporophyte is attached. The calyptra will soon fall off.

Another common moss is a tripinnately branched pleurocarp (carpet moss) that greatly resembles a tiny fern.

Occurring in small but dense patches is a robust acrocarp that bears leaves in two opposing rows (i.e., is 2-ranked) and thus is very flat. Moreover, the base of each leaf is split and clasps the base of the leaf just above it, similar to the leaves of an iris plant. (With it in the photo below is a smallish pleurocarp, the leaves of which tend to arch out away from the stem, i.e., are somewhat “squarrose.”)

The second stop on the Foray was a forested site across from the Lutheran Youth Center on Henry County Twp. Rd. 1D in Washington Township where we may have attained the staggering elevations of 685 feet. Here’s aerial view of the site.

On the ground the OMLA foray participants found a habitat totally different than the muck farm. This is a woods with undulating topography and abundant “coarse woody debris.” (CWD is forestry-speak for “logs.”)

At the margin of the woods along the road, a tree stump is densely occupied by a lichen.

The lichen is a fruticose (shrubby) one with very abundant and very small primary squamules. Short podetia are present, capped with proportionally large dark brown apothecia.

Also present here is a miracle of nature: an accidental terrarium!

(We discussed selling this on e-bay and retiring as millionaires!)
A closer examination of the photo shows the moss is a pleurocarp with ovate-acuminate, widely spaced leaves.

The final stop was the Rd. 2 and Wabash Cannonball Trail intersection. This is on the dirt road. The forest tract is east of this, though we mainly stayed on the trail. Here’s an aerial view of the trail.

The trail is an wide open area.

The trail wasn’t an especially productive site for finding bryophytes and lichens, but was nonetheless rewarding to visit. One treat was seeing a decidedly non-evil member of the buckthorn family (Rhamnaceae): New Jersey tea, Ceanonthus americanus. This species is a native low shrub that is the larval food plant for the spring azure and mottled dusky-wing butterflies (the latter quite uncommon in Ohio).
