Had great fun this past weekend at a "bioblitz" at Had great fun this past weekend at a "bioblitz" at a new nature preserve in southern Ohio's Pike County. It was nice to see this fruticose lichen, sinewed ramalina (Ramalima americana), on a dead branch in a low-lying wooded area. #lichens

Oooh ooh The rare "small hairy screw moss," Syntri Oooh ooh The rare "small hairy screw moss," Syntrichia laevipila, distinguished by its leaflike gemmae, hiding in a big patch of the very common marbled screw moss, S. papillosa (with globular gemmae)! This was seen this afternoon on the bark of a cottonwood tree in west-central Ohio's Montogmery County. #moss #botany #plants
What shoddy construction...they don't make mosses What shoddy construction...they don't make mosses like they used to! This one seen Sunday on a log in a fen at the lovely Bath Nature Preserve's "Tamarack Bog" in northern Ohio's Summit County has mostly broken leaf tips! Cheap! Oh wait...it's supposed to be that way! This is Orthodicranum viride, with fragile leaf tips that break off and serve as a means of asexual reproduction. OK then. #moss #plantlife #botany #bryophyte
This is a small cushion mossm in the family Pottia This is a small cushion mossm in the family Pottiaceae: Tortula obtusifolia, seen June 19, 2023 on a boulder at Caesar Creek in Warren County, Ohio. #moss
The leaf cells of the small cushion moss Tortula o The leaf cells of the small cushion moss Tortula obtusifolia viewed through a compound microscope at 400x are clearly pluripapillose (many-bumpy). It was collected from a boulder at Caesar Creek in Warren County, Ohio. #moss #botant #plantsofinstagram
I always forget...the one where you actually SEE t I always forget...the one where you actually SEE the tornado...is that the tornado watch or the tornado warning? Anyhow this scary weather scene looks strikingly like the sporophytes of Tortella humilis growing on a decorative boulder in a parking area at Caesar Creel Gorge in southwestern Ohio's Warren County. #moss #botany #bryophyte
This is one of the less abundant of the maybe 3 or This is one of the less abundant of the maybe 3 or 4 sphagnum mosses at Cranberry Bog. Growing in a low wet spot surrounded by hummocks occupied by Sphagnum capillifolium, this is Sphagnum recurvum. Technical features (blunt erose #moss #sphagnummoss
Dumortier's Liverwort (Dumortiera hirsuta) is a la Dumortier's Liverwort (Dumortiera hirsuta) is a large complex thalloid liverwort, about the size of the more familar Conocephalum and Marchantia, but smooth on top, lacking the pores and air chambers of those more typical types, and, uniquely, it has short hairlike scales on the lobe margins. A southern species, Dumortiera has been recorded but twice in Ohio, first in 1942 (Fairfield County by R.T. Wareham), and then, a pleasant surprise, by me a few days ago in a crevice in a rockhouse in Jackson County. #liverwort #bryophyte #botany
Sharpleaf hookeria moss, Hookeria acutifolia, is a Sharpleaf hookeria moss, Hookeria acutifolia, is a shiny carpet moss that lives in deep dark recesses of damp sandstone cliffs, mainly in the Appalachian region. It has remarkably large leaf cells, discernable with just a hand lens. This seen Tuesday in southern Ohio's Jackson County. #moss #botany #bryophyte
Bear-claw moss, Barbula unguiculata, is a light-gr Bear-claw moss, Barbula unguiculata, is a light-green cushion moss found on open calcareous ground. This was seen Saturday in central Ohio's Delaware County. #moss #plantlife
Tornado watch! It's the peristome of bear-claw mos Tornado watch! It's the peristome of bear-claw moss, Barbula unguiculata, that consists of 32 threadlike teeth forming a spirally tristed tube. This common moss was seen yesterday in central Ohio. #moss #bryophyte #botany
Liverwort sporophytes are simple little ephemeral Liverwort sporophytes are simple little ephemeral dainty things. Here are a few of "rustwort," Nowellia curvifolia, seen this afternoon on a log in southern Ohio's Hocking County. #liverwort
There are a small handful of lookalike Mnium speci There are a small handful of lookalike Mnium species that are bit hard to tell apart from one another. The keys ask about sexuality, which is hard to assess because they often aren't bearing any antherida or archegonia, and leaf cell size and shape. I'm thinking this one seen yesterday in a calcareous woodland in west-central Ohio's Clark County (where it would be a county record is Mnium lycopodioides (M. ambiguum). It's growing with Bryhnia graminicolor, which is abundant on these limestone cliffs. #moss #brtophyte #botany #plantlife
I spent the day at the herbarium of the Philadelph I spent the day at the herbarium of the Philadelphia Academy of Natural Sciences where I am a montly volunteer digitizing and databasing a fantastic 100-year old slime mold collection prepared by a remarkable Philadelphia industrialist named Hugo Bilgram. While Hugo could have been a lot better about indicating dates and locations for his specimens, they sure are meticulously arranged. This box--one of hundreds stored here--is about 2.5 inches across. #slimemold
Looking a little beat up by having just lived thro Looking a little beat up by having just lived through a winter, but merrily producing fresh new receptacles, it was a treat to see this "narrow mushroom-headed liverwort," Marchantia (formerly Preissia) quadrata on a limestone ledge along a rural road in southern Ohio's Adams County yesterday. #liverwort #bryophyte #botanybay

This is a "lantern moss," Andreaea rothii, seen ye This is a "lantern moss," Andreaea rothii, seen yesterday on a dry sunny sandstone ledge in southern Ohio. It is a member of a small primitive group of mosses that don't produce the typical spprophytes made up of a stalked capsule with a lid surrounded by teeth, but instead have the capsule is supported b a "pseudopodium" made of gametophyte tissue, and it splits lengthwise in four slits, perhaps discernable on the right edge of this specimen. The plants grow in small black tufts, with an aspect similar to various Grimmia species. #mosses #bryophytes #plants #nature #science
This ribbed bog moss, Aulacomnium palustre, seen y This ribbed bog moss, Aulacomnium palustre, seen yesterday on a wet sunny sandstone ledge in southern Ohio's Vinton County is freely reproducing asexually by means of tiny leaflike gemmae clustered at the tip and also sparsely distributed along the gemmiferous stalks. #botany #moss #bryophytes
"Comb moss," Ctenidium molluscum, is a carpet moss "Comb moss," Ctenidium molluscum, is a carpet moss with a featherlike growth form and leaves that are sickle-shaped and swept to one side (falcate-secund). As such it looks like several others such as Calliergonella curvifolia and Callicladium imponens. It's a bit shaggier (not a technical term) and through the microscope the leaves are distinctively bumpy-celled and toothed. This was seen Saturday at a former organic farm being converted to a natural area. #moss #botany #plants #science
