Oooh oooh oooh!!!! Wanted to see this for a long t Oooh oooh oooh!!!! Wanted to see this for a long time...even tried raising it from clumps of what is said to be its host plant, Bazzania trilobata, and lo here it is, the inaptly named "goldcap moss-eater" (moth), Epimartyria auricrinella, perched on a different liverwort, the simple thalloid Pellea epiphylla. Apparently it's primitive, reflected on a moss numbering system/checklist, where it's listed as Hodges #0001. This was seen today in southern Ohio. #liverworts #bryophytes #botany #moths #lepidoptera
There is a confusing array of leafy liverworts tha There is a confusing array of leafy liverworts that have untoothed, unlobed leaves with a "succubous" leaf insertion and no underleaves. The fact that these leaves are not much longer than wide and have a marginal border of slightly larger cells makes me think it is in the genus Solenostoma. It was seen this afternoon on a wet sandstone cliff in southern Ohio's Vinton County. #liverworts #ohioplants #botany #bryophyta
At the signpost up ahead, your next stop, The Live At the signpost up ahead, your next stop, The Liverwort Zone. Liverwort leaf cells have organelles called "oil bodies." I don't know what their function is, but they are sometimes useful in identification. This specime that might be a Solenostoma (one of several lookalike genera of entire-leaved ones with no underleaves) shows 2-4 large granular oil bodies per cell. This is from a plant seen today on a wet sandstone ledge in southern Ohio's Vinton County.#liverworts #bryophytes #botany #plants
Flower hunting Sunday at Wayne National Forest in Flower hunting Sunday at Wayne National Forest in southern Ohio's Perry County, I was encouraged by @shaunpogacnik to look at this peat moss growing in a large patch at the margins of a pond. A microscopic feature--branch leaf cross-sections showing the photosynthetic cells equilateral- triangular and more broadly exposed on the convex side of the leaf--and, perhaps evident in this photo, branch buds in the capitulum in pairs (not solitary), point to flat-top bogmoss, Sphagnum fallax.
I'm in Philaelphia. Also in Philadelphia is a spec I'm in Philaelphia. Also in Philadelphia is a spectacular park system, the Wissahickon Valley, that's aptly described as one of the most beautiful urban parks in the world. Here's a little old wood shingle-roofed structure adorned with, of all things, fruticose lichens in the genus Cladonia--not something you'd expect to see in one of the largest cities in the US! #urbanlichens #fruticoselichen #cladonia #lichens
It was interesting to see this Funaria hygrometric It was interesting to see this Funaria hygrometrica, a common moss usually found along rairoad tracks, fire pits and the like, on a limestone boulder in a beautiful woodland creek at Indian Mounds Reserve in west-central Ohio's Greene County. I'm trying to turn it into the very rare Funaria america/Entosthodon americanus, which will require the capsules when ripe to be smooth not furrowed, and the peristome to lack an annulus. #mosses #funaria #sporophytes #bryophytes #plants #botany #ohioflora

Mnium stellare is easily told by leaf features tha Mnium stellare is easily told by leaf features that can be seen, albeiot barely, with just a hand lens. The leaves lack the border of linear cells seen in other members of the genus (as well as in its relatives Rhizomnium and Plagiomnium), the costa (nerve) ends well below the apex, and the marginal teeth are small and blunt. This was seen yesterday in south-central Ohio's Fairfield County, not in a fair field but a rocky woodland. It was growing on huge sandstone boulder. #mosses #bryophytes #plants #ohiobotany #mnium

Hairy veilwort, Metzgeria crassipilis, is a simple Hairy veilwort, Metzgeria crassipilis, is a simple thalloid liverwort distinguished from other members of its genus by discoid squamulose gemmae clustered in spots in the upper surface of the lobes (visible, but only barely so, in this photo). This was seen today on the vertical face of a huge slab of sandstone in south-central Ohio's Fairfield County. #liverworts #bryophytes #botany #plants
The great Edwin "Ketch" Ketchledge, my first moss The great Edwin "Ketch" Ketchledge, my first moss teacher, who, a complete gentleman, would never utter a salacious comment, nonetheless called this (or something closely related) "sexy moss" because...look at all those sporophytes!! This is (or may be) brookside feather moss, Hygroamblystegium fluviatile, seen a few days ago on a damp semi-shaded limestone ledge in west-central Ohio's Greene County. (Amblystegium varium is a close look-alike.) #mosses #bryophytes #botany
Many members of our largest moss family, the Potti Many members of our largest moss family, the Pottiaceae, have leaf cells that are minutely bumpy (papillose). Although this is a microscopic feature, it can often be discerned indirectly by the dull soft matte finish look to the leaves. That is the case with this Porter's screw moss, Tortula porteri. It's a small lime-lover seen on rock yesterday in west-central Ohio's Greene County. #mosses #bryophytes #plants #botany #ohioplants
Was excited to see a lot more warrior moss, Timmia Was excited to see a lot more warrior moss, Timmia megapoliana at the limestone-dominated woodland in west-central Ohio's Greene County where I had seen only one small patch before, and this time with sporophytes! The calyptra sometimes clasps the base of the capsule, as seen here in the foreground. #mosses #bryophytes #sporophytes #plants #botany #timmia
A peculiarly whitish-green cushion moss of wet see A peculiarly whitish-green cushion moss of wet seepy spots can either be this Pohlia wahlenbergii or a lookalike in the genus Philonotis. The leaf cells viewed microscopically tell them apart: smooth in Pohlia, slightly bumpy at the ends in Philonotis. This was seen a couple weeks ago in west-central Ohio's Greene County, but identified only just now. #mosses #bryophytes #botany
Straddling the border between foliose and crustose Straddling the border between foliose and crustose lichen types, "squamulose" ones consist of small overlapping scales. This" limy-soil stipplescale" (or as iNaturalist calls it, "jellytot earthscale lichen"), Placidium squamulosum was once thought to be rare in Ohio, but it may have just been overlooked as it seems to be a reliable sight on damp open calcareous barrens such as the shale-strewn cedar grove along Alum Creek in central Ohio's Delaware County where I saw it yesterday. #lichens #fungi
Ooh ooh...another opportunity to say "eponymous"! Ooh ooh...another opportunity to say "eponymous"! Behold the eponymous reticulated surface of Parmotrema reticulatum, a feature that more often is barely evident. This was seen Sunday on a redcedar tree in southern Ohio's Adams County. #folioselichen lichens #fungi
Had a great time on Sunday botanizing with @shaunp Had a great time on Sunday botanizing with @shaunpogacnik and @the_land_philosopher at Lynx Prairie in southern Ohio, who kindly showed me this "hidden spikemoss," Selaginella ecliptes. I learned that it is a narrowly distributed calciphile that can be distinguished from the more widespread meadow spikemoss, S. apoda, by the long-pointed and recurved upper leaves. Spikemosses are seedless vascular plants in the phylum Lycophyta, along with clubmosses and quillworts. #spikemoss #botany #lycophytes #ohioplants #selaginella
A small fraction of lichens have as their photosyn A small fraction of lichens have as their photosynthesizing partner not the usual eukaryotic green alga but instead blue green cyanobacteria. Most of these weird ones have a more more homogenous (not layered) internal structure compared with typical lichens and a gelatinous consistency when wet. Also a blue-green color. This is one of them, Enchylium (Collema) coccophorum, somewhat rare I am told, seen on the ground in a calcareous prairie glade in southern Ohio's Adams County. #lichens #cyanolichens #fungi #cyanobacteria
This is Thelia asprella, seen yesterday at the bas This is Thelia asprella, seen yesterday at the base of a redcedar tree in southern Ohio's Adams County. It's julaceous (wormlike) and, as do many mosses that have the microscopic trait of bumpy leaf cells, it has a soft matte-finish aspect to the surface. #mosses #plants #gametophytes #botany #bryophytes
