Aka Lophozia bicrenata.
Growing on sandy soil by the side of a woodland trail.

The Hepaticae and Anthocerotae of North America by Rudolf Schuster (vol. 2, 1969) describes this liverwort as “An extraordinarily widespread species…with truly ‘weedy’ propensities,” but this observation of Isopaches bicrenata is only the fifth recorded in iNaturalist for all of North America. Although common, it’s inconspicuous and apparently unnoticed.

This lichen was growing on a Red maple in the middle of a dried out vernal pool. I still managed to get my boots a bit wet, while trying to get to the lichens to photograph them. The H. minarum was growing alongside Punctelia missouriensis and some Cladonia.

Lobes are smooth, lacking pseudocephyllae. Much of the thallus surface is covered with brownish isidia, i.e., small projections which act as structures for vegetative reproduction. The isidia break off and are carried to other places by the wind, giving rise to a new thallus.

Brackish pond shore exposed by evaporation. Floral scales <2mm long. Stems thread-like, less than 1 mm in diameter. J-shaped to U-shaped tubers. M. Arsenault et al., Sedges of Maine 2013. Third iNaturalist observation of this species in New England.

A known population. First iNat posting on the 13 state northeastern region. This is the northeastern-most population in the U.S. I noted no peppery taste in the leaves. This is a sturdy perennial with rhizomes, up to about three feet tall but can bloom at 12 inches as well. State-threatened species.

On Trametes versicolor. Turns dark purple in KOH, then fades to red. Ascospores warted, 1-septate, apiculate with pointy projections, 16-25 x 4-5.5µm. Conidiospores broadly ellipsoid, 1-septate, 12-15 x 7.5-8µm.

On a small common birch snag. Only one apothecium, yellow. Thallus and apothecium K-. Lobes closely attached with abundant white rhizines. Spores about 10 x 5-6 um, 1-celled but with twin lens-shaped vacuoles, dozens per ascus.

Sur un petit chicot de bouleau commun. Une seule apothécie, jaune. Thalle et apothécie K-. Lobes étroitement attachés avec d'abondantes rhizines blanches. Spores d'environ 10 x 5-6 um, unicellulaires mais avec des vacuoles jumelles en forme de lentilles, des dizaines par asque.

Eupatorium. North 40, Floyd Bennett Field, Brooklyn, NY. Rather similar to Eupatorium hyssopifolium but leaves appear to be wider. Last 3 photos from a slightly different site further along trail but seems to be the same species as first 2 photos.

On London plane tree. Picture 8 shows leg IV with a tactile seta on tarsus and no tactile seta on tibia; Picture 6 shows three setae of rallum on chelicera; Picture 7 shows venom apparatus is only on movable finger; Pic 9 is Leg I and Pic 10 is Leg III. The last three pictures show trichobothria confined to proximal half of fixed finger.

All 8 legs have five segments.

Seeds dimorphic, which rules out S. maritima. Seeds well over 1.7mm wide, which rules out S. calceoliformis. Perianth segments keeled and very thick. Fits well with S. rolandii (the only other species known from the region). Specimen was collected roughly a kilometre from site where in situ picture was taken.

Seeds dimorphic (ruling out S. maritima). Seeds over 1.7 mm wide (ruling out S. calceoliformis). Perianth segments keeled (varying from obscurely keeled to clearly so) and very thick. Fits well with S. rolandii, which is the only other species known to be present in the region.

In Ecology Park, Brooklyn.

I'm going long on this one, and hypothesizing a species. I can't find any other small yellow bee that could occur in the area of NYC.

On vertical concrete wall covered with other mosses and lichens. Some pictures were taken after spraying with water. Both dry and wet states can be seen here. Branches curve upward when dry and nearly horizontal when wet. Leaves can be ecostate, short-double costate, or long-single costate. Seta can be immersed or short-exerted.
