Unfortunately I don't have accurate coordinates, but this was observed during field work in this area.
First lake
Invasive species
I think.....
ID confirmed with specimen - distal part of leaves not sharply keeled and distal part of bristles extensively papillose (thus ruling out N. ericoides); on open edge of abandoned sand/gravel pit on dry soil
Large lobes, esorediate, not hairy, and acutely raised veins on the underside. On a log over a small slopey stream.
Identification confirmed by Frances Anderson
larger thalli to 4-5 mm wide; abundant rhizoids on ventral midline; @crobillard am I on the right track here? I don't think the habitat was particularly calcareous, so not a good sign for this species
medulla white, KC-
soralia isidioid and not marginal
M.J. Oldham # 11445, specimen record, replicates at MICH 1366381, TRTE, NHIC# 03276 (home); identified as Carex comosa X C. hystericina by AA Reznicek 1991 (sub C. ? hystericina X pseudocyperus det. MJO); marl swamp; "teeth outcurved, ca. 0.9 - 1.4 mm long" (AA Reznicek)
Downward sloping sepals
@seanblaney @michael_oldham am I on the right track here?
Leaves fairly branched, but consistently with one bladder on all stems seen. @thilokrueger
Unsure what this is, along trail, Wrights Creek
I didn't realize what it was until it was too big to remove in my own. Edit 2023/08/23 I managed to get it down, and it is currently wrapped in plastic waiting for disposal.
Both subsp. americanus (native to North America) and subsp. australis (introduced to North America) are found at this site, sometimes growing intermixed. In the photos the former is indicated with an “N” and the latter with an “I”. On the date I visited this site, 16 September 2019, these are the differences I observed with living stems between the two subspecies:
•Relative stem height: subsp. americanus usually shorter, subsp. australis usually taller.
•Relative stem spacing: subsp. americanus usually more dispersed, subsp. australis usually denser (rarely solitary).
•Stem breaking: subsp. americanus fibrous and hard to break off, subsp. australis often breaks off easily.
•Stem color (lower/older internodes): subsp. americanus red and often shiny, subsp. australis yellow-green and not shiny.
•Stem texture (lower/older internodes): subsp. americanus smooth, subsp. australis minutely ridged.
•Stem & leaf sheath dots: subsp. americanus often present, subsp. australis absent.
•Leaf condition: subsp. americanus has lots of senescence, subsp. australis generally are healthy.
•Margins of upper leaves near panicle: subsp. americanus finely serrated, subsp. australis coarsely serrated.
•Sterile stems more abundant than fertile: subsp. americanus yes, subsp. australis no.
•Panicle branches for panicles of similar length: subsp. americanus fewer, subsp. australis more.
•Panicle branch spacing: subsp. americanus farther, subsp. australis closer.
•Flowering status: subsp. americanus finished flowering, subsp. australis flowering.
There probably are other characteristics I overlooked that distinguish these two subspecies from each other. Perhaps these characteristics listed above hold up at other sites in North America. I don’t use leaf color to tell them apart because although some clones of subsp. australis are strongly blue-green, some clones of that subspecies are more green or yellow-green.

@seanblaney as discussed.....
Found while out with David Fielder. Two bigger leaves on stem where P. clavellata only has 1. Very long thin spurs
very common on dunes here
Growing on rocky shore of a lake.
rosette of huge basal leaves only
black spruce roots and lower branches; soralia mostly laminal on flat lobes, brown lower surface of lobes darkening towards centre
Red maple. Many thalli
Growing on old growth Nothofagus bark in humid moderate elevation forest. The odd camera angle is because it was very high off the ground and I couldn't reach high enough for any other perspective.
A rare (white) Albino showy lady slipper found in manitoba not a dwaft lady slipper i know this because it's the same size as a showys flower head and is missing the twisted side flower pedals.
wpt 1260. White form; =E. russeolum var. albidum. Third photo shows it intermixed with typical russet form
On fallen bigtooth aspen.
many thalli on balsam fir in balsam fir/black spruce swamp
On rock retaining wall in graveyard: capitate soralia; white medulla; white-tipped, black rhizines
@seanblaney @sedgequeen agree?
wpt 1224
Narrow, serrated leaf. Comparison Vaccinium angustifolium on left, Vaccinium myrtilloides on right
A presumed native occurrence (1st for PEI); at the only basalt outcrop on PEI
First known location for the park
the introduced ssp. parviflora, which iNaturalist doesn't recognize. Twice as large as the native and broader habitat tolerance (various old field and disturbed vs. just rocky rivershores and saltmarsh margins).
