Traponora varians (formerly Pyrrhospora varians) i Traponora varians (formerly Pyrrhospora varians) is a common crustose lichen found on tree trunks and branches. It can be recognized by its its thin warty grayish-beige thallus and abundant small pale brown apothecia. This was seen Saturday on a redbud tree in a calcareous prairie in west-central Ohio's Miami County. #lichens #fungi #ascomycota
A pretty yellow lichen that's similar and, I assum A pretty yellow lichen that's similar and, I assume, closely related to the foliose "candleflame lichens" in the genus Candelaria but is strictly crustose and bears abundant spore-producing apothecia, this is a "goldspeck lichen," genus Candelariella. It was seen Saturday on a redbud branch in a calcareous prairie in west-central Ohio's Miami County. #lichens
This not-quite-foliose lichen (it's said to have a This not-quite-foliose lichen (it's said to have a "placodioid" growth form) is Protoparmeliopsis muralis, formerly known as Lecanora muralis. A cosmopolitan species that is very common and abundant in many places wordwide, it's kind of rare in Ohio, and this might be its grandest presentation, on a rock in a calcareous prairie in west-central Ohio's Miami County, where it posed for this photo yesterday. #lichens
As usual, it's spoon-leaved moss, Bryoandersonia i As usual, it's spoon-leaved moss, Bryoandersonia illecebra, seen this afternoon on the ground in a wet meadow in central Ohio. I over-collect this moss out of eagerness to find a rare European look-alike that may occur in Ohio, but hasn't been pickled up yet. #mosses #bryophytes #botany
Since they're so often seen together on granitic b Since they're so often seen together on granitic boulders in places like southern Ohio where they were photographed yesterday this Hedwig's ciliate moss (Hedwigia ciliata) and dragon cladonia (Cladonia squamosa) seems like the best of friends. Alas, they're probably mortal enemies, competing for space, but it's nice to think otherwise. #mosses #lichens
Since they're so often seen together (on tree trun Since they're so often seen together (on tree trunks in park-like settings such as the OSU campus where they were photographed yesterday) this marble screw moss (Syntrichia papillosa) and tiny bristle moss (Orthotrichum) seems like the best of friends. Alas, they're probably mortal enemies, competing for space, but it's nice to think otherwise. #mosses
Bird's-claw beard-moss, Barbula unguiculata, is a Bird's-claw beard-moss, Barbula unguiculata, is a common little moss that forms bright patches on bare soil in lawns and parks. Note the light green leaves that are lance-shaped and end in a projecting extension of the mid-nerve. It was seen this afternoon in central Ohio's Delaware County. #moss #mosses #botany #plants #nature #pottiaceae
Looking a little ragged (but who wouldn't who live Looking a little ragged (but who wouldn't who lives 24/7 in the woods?), this Bluntleaf Anomodon Moss, Anomodon minor, is is growing about knee-high on a tree base in southern Ohio's Vinton County. #mosses #bryophytes #botany #plantlife
Sharp-pointed earwort is a leafy liverwort with co Sharp-pointed earwort is a leafy liverwort with complicate-bilobed leaves, i.e., they are folded mitten-like, and the smaller lobe (the thumb of the metaphorical mitten) is on top, and is angled outward. This is fairly common on wet sandstone cliffs such as the one in southern Ohio's Vinton County where it was seen yesterday. #liverworts #botany #green #bryophyte
The foliose lichen genus name "Heterodermia" trans The foliose lichen genus name "Heterodermia" translates to something akin to "different-skinned," alluding to the fact that some species have only an upper cortex, not a lower one. I believe this is one of those species, Heterodermia obscurata, further distinguished by an orange undersurface, but to see that would have required breaking off a piece of it, which would be wrong because it is a lone specimen on a prominent tree in a park. #lichens #fungi #nature
And the prize for the least appropriate botanical And the prize for the least appropriate botanical term goes to (drumroll please) THE LIVERWORT "PERIANTH." Those spade-shaped structures at the tips of the branches of this New York scalewort (Frullania eboracensis) are where the egg-containing archegonia and later the sporophytes are borne. Termed "perianths," this a doubly bad word usage because (1) it is properly a floral anatomy term and liverworts are about as far from flowering plants as you can get, and (2) the word perianth means "around the anthers" (male floral organs) and these so-called perianths surround female organs!

This moss, seen Friday, is growing on the ground o This moss, seen Friday, is growing on the ground on a hillside in southern Ohio's Vinton County. It's an acrocarp (cushion moss) with leaves that are involute (upwardly rolled along the margins), hence it seems to be a Weissia. Our common species is Weissia controversa. The odd things is the sporophytes; this specimen has them the spear stage (not visible in the photo). Whenever I've seen W. controversa in December it has had more mature sporophytes with plump capsules. Wonder if it's some other species? #mosses #bryophytes #plants #botany #nature
It's Pogonatum brachyphyllum! Seen today on a damp It's Pogonatum brachyphyllum! Seen today on a damp sandstone ledge in southern Ohio's Vinton County, this is one of just a few mosses that have a persistent protonema--the alga-like stage of gametophyte development that occurs before the growth of leafy "gametophores." As evidenced by hairy calyptrae (caps), it's an obvious member of the haircap moss family Polytrichaceae. It's rather rare in Ohio. The Flora of North America (vol. 27) has this to say about it: "Pogonatum brachyphyllum is endemic to eastern North America, and it has a more southerly distribution than P. pensilvanicum. The leaves of P. brachyphyllum are entire, short and broad, and appear succulent because of tall, closely packed lamellae. The calyptra is yellowish to reddish brown, contrasting with the rich, green protonemal mat." #mosses #bryophytes #plants #botany #nature
Cranberry Bog State Nature Preserve is a floating Cranberry Bog State Nature Preserve is a floating island in Buckeye Lake in east-central Ohio's Licking County that formed when the valley it resides in was flooded in the 1800's as part of a canal project. Sphagnum mosses are abundant there. This is the dominant species, Sphagnum capillifolium, as seen yesterday on a recon trip to see why they seem to be faring poorly. #mosses #bryophytes #botany
The tiny (the scene shown is about 1.5 cm across) The tiny (the scene shown is about 1.5 cm across) but sometimes abundant "verdigris tufa-moss," Gymnostomum aeruginosum (family Pottiaceae), is a calciphile that nonetheless often appears on sandstone. This colony was seen Thursday on a damp shady rock ledge in southern Ohio's Athens County. #mosses #nature #bryophyte
Boulder broom moss, Dicranum fulvum, does indeed, Boulder broom moss, Dicranum fulvum, does indeed, as the common name suggests, have a fidelity to boulders. It somewhat resembles common broom moss, D. scoparium, which occurs sparingly on boulders but is more of a ground-dweller. Compared with that species, boulder broom moss is a bit smaller, and has leaves that are more crisped-curled. This was seen Thursday in southern Ohio's Athens County. #moss #bryophytes #plantsofinstagram #bryophytes
This is the undersurface of a leafy liverwort, Jub This is the undersurface of a leafy liverwort, Jubula pennsylvanica, at 100x. Very Frullania-like (differing mainly in the leaf shape, having the upper lobes somewhat pointed instead of smoothly rounded), it has the lower lobes modified into little pitchers. This was seen today in southern Ohio's Athens County. #liverworts #botany #plants #nature #bryophytes
Because it is tan, fluffy, and cute, this has been Because it is tan, fluffy, and cute, this has been called "the golden retriever of liverworts." It's handsome woolywort, Trichocolea tomentella, an Ohio rarity, seen yesterday on the ground in a damp recess in a rock overhang in southern Ohio's Athens County. #liverworts #bryophytes #botany #plants
This is shield liverwort, Cheilolejeunea (formerly This is shield liverwort, Cheilolejeunea (formerly Leucolejeunea) clypeata, an ID made tentatively in the field by its incubous leaf insertion, and later confirmed at the microscope by its complicate bilobed leaves, and the presence of just one or two large granular oil bodies per cell. This was in a shady rock recess in southern Ohio's Athens County. #liverworts #bryophytes #botany #plants
Looking like a water moss (Fontinalis) to which it Looking like a water moss (Fontinalis) to which it is related (same family) but with very long-pointed leaves, this is "hairlike claw moss," Dichelyma capillaceum, growing on the base of a tree in a hardwood swamp in southern Ohio's Gallia County that I had fun exploring with Joshua Copen on Sunday. It's something of a rarity. #mosses #bryophytes #plants #botany
