Many of the trees on the grounds of the Harding Me Many of the trees on the grounds of the Harding Memorial in Marion Ohio are adorned with hooded sunburst lichen, Xanthomendoza fallax. Note the soredia-producing lip-like expansions of the lobe tips. #lichens
This is Tortula (formerly Desmatodon) porteri, a m This is Tortula (formerly Desmatodon) porteri, a moss in the family Pottiaceae, many of which, including this one, have minutely bumpy (papillose), not smooth, leaf cells. That is a microscopic feature, and while I haven't read about this or heard it from an expert, it seems to me that mosses with leaf cells so ornamented have a light green matte finish compared with smooth-leaved plants that are deeper green and shiny. Thsi was seen on a flat limestone rock on an open forest floor in southern Ohio's Highland County. #moss
Gathering moss specimens for this weekend's moss w Gathering moss specimens for this weekend's moss workshop at The Highlands Nature Sanctuary, I found a branch adorned with this Ohio bristle moss, Orthotrichum ohioense, along a rurual road in central Ohio's Delaware County. I like the stylish stocking caps it wears (calyptrae covering the sporophyte capsules). #botany #moss #bryopthyte
Wavy broom moss, Dicranum polysetum, has broad lea Wavy broom moss, Dicranum polysetum, has broad leaves (for a Dicranum) that are shiny and wavy-textured. The leaves emerge off the stem equally in all directions (i,e, are not windswept-looking), and the stems are densely felted with reddish tomentum. It is much less common here than its congenor and frequesnt associate, Dicranum scoparium (common broom moss). This was seen yesterday in an open Virginia pine woodland on a former surface mining site in southern Ohio. #moss #bryophyte #nature #botany
Tetraphis pellucida (four-toothed moss, so-named f Tetraphis pellucida (four-toothed moss, so-named for a sporophyte feature) produces these cute birds-nest-like gemmae cups. This was seen in the rain yesterday on a well-decayed stump in in southern Ohio. #moss #botany #bryophyte
The apples aren't ripe yet! This is "apple moss," The apples aren't ripe yet! This is "apple moss," Bartramia pomiformis, seen yesterday on a wet shaded sandstone ledge in southern Ohio, bearing sporophytes that are spear-shaped now but will be topped with plump round sporangia in a couple/few months. #bryophytes #botany #moss

I'm greatly enjoying a close reading of "The Liche I'm greatly enjoying a close reading of "The Lichen Book," a masterpiece 648-page identification guide self-published (self-printed as well) in 1947 by polymath rennaissance man Guy Nearing, a New Jersey nursery owner better known for developing rhododendron hybrids. See this page spread with his drawings showing unaided-eye views (uncircled), a hand-lens view (in single-line circle) and a compound microscope view (in double-lined circle) of Physcia stellaris. Given the breadth, depth, quality and usefulness of this unique work, one wonders why it isn’t more well known, and evidently was not widely adopted even when it was current, as it seems to bridge the long gap in comprehensive works between Bruce Fink’s "The Lichen Flora of North America" (1935) and Irwin Brodo, Stephen Sharnoff, and Sylvia Sharnoff’s "Lichens of North America" (2001). #lichens
Lesser smoothcap, Atrichum angustatum, growing on Lesser smoothcap, Atrichum angustatum, growing on a sandstone ledge in southen Ohio a few days ago. The genus name means "no hairs," setting it apart from most other members of its family, the Polytrichaceae, which means "many hairs." All this talk about hairs is in reference to a covering, or in this case a lack of it, on the calyptra (the cap covering the developing sporophyte). #moss
Common on branches, a little button-shaped clump o Common on branches, a little button-shaped clump of moss with short stems, some topped by barely emergent sporophytes sporting calyptrae that resemble neat winter stocking caps, this is Ohio bristle moss, Orthotrichum ohioense, as seen a few days ago in southern Ohio. #moss #plants #bryophyte
Greater featherwort, Plagiochila asplenioides, is Greater featherwort, Plagiochila asplenioides, is a fairly large leafy liverwort with obliquely inserted ovate leaves that are gently folded lengthwise and toothed at the tips. The leaves remind me of the chaps you wear for safety while chainsawing. This specimen was seen a few days ago on a smalll rock in the floor of a mixed hemlock-hardwood forest in southern Ohio. The associated moss is Oxyrrhynchium (formerly Eurhynchium) hians. #liverwort #botanical #bryophyte #plants
It's well known that botanists use a lot of specia It's well known that botanists use a lot of specialized terms. Less well known is that, in botany, some regular English words mean something different from what you are accustomed to. For example, in the phrase "...gynoecia can almost always be found" (structures associated with gynoecia being necessary to separate two very similar liverwort genera), the word "always" actually means "never." Hence I'm only guessing based on some difficult to ascertain vegetative features that this leafy liverwort with entire succubously arranged leaves and no underleaves is Syzygiella autumnalis (formerly known as Jamesoniella autumnalis). It was seen Saturday atop a sandstone boulder in a southern Ohio woodland. #liverwort
Rah Rah Sis Boom Bah...yay team! See the pom-poms? Rah Rah Sis Boom Bah...yay team! See the pom-poms? iNat has no common name. NatureServe Explorer calls it "boar moss." I call it "cheerleader moss." Brothera leana is a small moss in the family Leucobryaceae that reproduces solely by clusters of spindle-shaped brood leaves in tufts at the stem apices. This none-too-common little bryo was seen Thursday at the base of a pine tree in southern Ohio's Hocking County.
Shaggy fringe lichen, Anaptychia palmulata, seen a Shaggy fringe lichen, Anaptychia palmulata, seen at the base of a tree in an open woodland in southern Ohio on Christmas day, seems to be in the holiday spirit, displaying festive wreaths (cleverly disquised as apothecia). #lichen
Winter is not a dormant season! The two narrow upr Winter is not a dormant season! The two narrow upright sticks --one slightly right of center and the other at the left-- atop these leafy Aulacomnium heterostichum (one-sided groove moss) gametophytes are sporophytes. Indeed, they are plants--plants that began their lives as fertilized eggs about (I'm guessing) 3 weeks ago, and by next May they will be mature and releasing spores. Plants that will be growing throughout the winter. Winter is not a dormant season! #botany

It's sporophytes of "rusty ragged moss, Sciuro-hypnum plumosum (formerly Brachythecium plumnosum). This was seen today on a small rock on the floor of a southern Ohio woodland. #botany

This lovely little leafy liverwort seen a few days This lovely little leafy liverwort seen a few days on a damp shaded sandstone ledge in southeastern Ohio is called Radula obconica. From this view it could be mistaken for several other incubous-leaved ones, but a microscope view shows no underleaves and only one, large, oil body per cell. The word "radula" derived from Latin means a scraper of some sort, and is familiar to zoologists as being the organ many mollusks use to scape algae off of rocks, etc. The meaning of "radula" with respect to this liverwort is obscure, at least to me. #liverwort #botany #bryophytes
