Liverworts of Illinois - Working List

@abelkinser @bob375 @mrostrowski @wildlander @sedge I couldn't find a list of liverworts known from Illinois, and many of the collections on Bryophyte Portal seem to be misidentified, so I used Stotler & Crandall-Stotler (2017) to compile a list of liverwort species whose ranges includes Illinois. Please let me know if you have any comments/corrections/suggestions. Species with a question mark after them have ranges that possibly include part of Illinois, but are not mentioned explicitly as occurring in/around Illinois.

According to NatureServe, the Illinois Plagiochila retrorsa site is Little Grand Canyon. Should be distinguishable by strong teeth on the leaves.

Thanks! I bet we can get 1-3 new ones in the state by the end of the year.

Love it! Thanks for putting this together. I did the same years ago in a notebook. I’ll see if I can find it. What about Plagiochila sharpii? Synonym of P. retrorsa? I also have reprints of Stolter articles for species lists for different natural areas of so IL that I can cross reference with list.

I have seen P. retrorsa at Little Grand Canyon years ago. I bet I can relocate.

Here is a list of taxa from Stolter so IL published reports that are not on your list. Some are likely synonyms due to taxonomic changes I’ve not kept up with, but some are definitely missing from list.
Calypogeia trichomonis
Cephalozia connivens
Cephalozia pleniceps
Cephoziella hampeana
Kurzia sylavatica is reported from Lusk Creek and Little Grand Canyon
Lejeunea laetovirens
Leucolejeunea clypeata (Cheilolejeunea clypeata on iNat, I see this one throughout Shawnee Hills)
Leucolejeunea unciloba
Lophocolea cuspidata
Lophozia bicrenata
Marsupella emarginata
Marsupella sphacelata
Metzgeria furcata
Odontoschisma prostratum
Riccia austini
Riccia dictyospora
Riccia membranacea

I'll include the range description Stotler & Crandall-Stotler give for each of those species here, for convenience.

Calypogeia trichomanis: "The name Mnium trichomanis L. (5 Calypogeia trichomanis (L.) Corda) is a “nomina utique rejicienda” or rejected name listed in the International Code of Botanical Nomenclature (Wiersema et al., 2015: 423) and is not to be used. Plants labeled as such rarely, if ever, represent C. azurea Stotler & Crotz and are most likely referable to C. muelleriana (Schiffn.) M¨ull. Frib., or, if they are from the southeastern United States and have blue oil bodies, C. peruviana Nees & Mont. We have confirmed C. azurea from the Pacific Northwest; it might also occur in eastern Canada. Calypogeia azurea is a distinct species, not simply a replacement name for C. trichomanis."

Cephalozia connivens: synonym of Fuscocephaloziopsis connivens, listed above.

Cephalozia pleniceps: synonym of Fuscocephaloziopsis pleniceps. "[var. pleniceps] is in the west from Alaska and the Yukon south to California, Wyoming, Nevada, and New Mexico, and in the east from Greenland to Ontario, New England, and New York. It is in Europe from Scandinavia and Russia south to the British Isles, France, and Italy, and in Siberia and the Russian Far East... [var. caroliniana] is known only from the type in North Carolina."

Cephoziella hampeana: listed above

Kurzia sylavatica: listed above, I'll remove the question mark

Lejeunea laetovirens: in Stotler & Crandall-Stotler (2017) as Lejeunea laetevirens; "This species is in the southeastern United States from Florida north to West Virginia; it is widespread in northern South America, the West Indies, and Central America." I'll add it to the list.

Leucolejeunea clypeata: in Stotler & Crandall-Stotler (2017) as Cheilolejeunea clypeata (as you know), I'll add it to the list.

Leucolejeunea unciloba: in Stotler & Crandall-Stotler (2017) as Cheilolejeunea unciloba; "This species is found from Rhode Island south along the outer coastal plain to Florida and west to eastern Texas; it is also in Mexico, Peru, Brazil, and South Africa." I'll add it to the list.

Lophocolea cuspidata: in Stotler & Crandall-Stotler (2017) as Lophocolea coadunata, with some very complicated taxonomic explanations for why.

Lophozia bicrenata: in Stotler & Crandall-Stotler (2017) as Isopaches bicrenatus, listed above.

Marsupella emarginata: "This transcontinental species is found from Alaska south to California, Colorado, and Wyoming in the west and in the east from Greenland and Ellesmere Island south to Nova Scotia, Quebec, and throughout New England, to New York, North and South
Carolina, Georgia and Tennessee, to Michigan and Minnesota. It is also in central and western South America and throughout northern and central Europe, North Africa, western Asia, and the Russian Far East." I'll add it to the list.

Marsupella sphacelata: "This species is widespread from Alaska to British Columbia and Alberta to Idaho and California, and in the east from Greenland to Newfoundland, Quebec, and Ontario, through New England and south to North Carolina, Tennessee, and Georgia. It is widespread in both Europe and Japan." I'll add it to the list.

Metzgeria furcata: "In North America, this species is definitively known only from Vermont; it is widespread in Europe." I'll add it to the list with a question mark.

Odontoschisma prostratum: in Stotler & Crandall-Stotler (2017) as Odontoschisma sphagni, listed above.

Riccia austini: in Stotler & Crandall-Stotler (2017) as Riccia lamellosa, listed above.

Riccia dictyospora: This species is found in the eastern United States from Minnesota to Connecticut and south to Texas and Georgia." I'll add it to the list.

Riccia membranacea: "This species is found in the eastern United States west to Oklahoma and Texas; it is also in Mexico, South America, and tropical Africa." I'll add it to the list.

I've been combing through it. I don't have experience with that kind of formatting, so I've been working on figuring out how to decipher it. Eastern Illinois University has a number of published bryophyte inventories I've been working through, including the one describing the finding of Nardia at Rocky Branch: https://thekeep.eiu.edu/cgi/viewcontent.cgi?article=3810&context=theses

Stotler & Crandall-Stotler describe Nardia lescurii as "an endemic of southeastern North America," which seems odd. I'll add it to the list.

Note: Calypogeia sullivantii was swapped into Asperifolia sullivantii, following the findings of Bakalin et al. (2022). In our region, this is the only species affected.

Thanks Ryan! What do you mean by observed? On iNat?

Very helpful and detailed organization. Much appreciated Ryan.
