On dolomite with lots of chert and quartz throughout. Seems to be associated with hard siliceous rocks, though it grows on dolomite too.

Discovered and photographed by Michael Terry. Rock outcrop under dense canopy of sugar maple, fir, cedar, and other mixed woods. A few clumps within 20 feet of each other. Rachies appear slightly glandular, long-triangular shape like C. bulbifera but without bulblets on frond underside, occasional vestiges in axes. A sample was collected (Terry #5085) and sent to the University of Michigan Herbarium; Dr. Anton Reznicek confirmed it is Cystopteris laurentiana on 3/6/2023.

goatprairie描述
On a bluff prairie dolomite outcrop with Calogaya pusilla. A new species for Wisconsin if so.
Edit: Yellow pruinose lobate thallus with central laminal soredia and/or labriform soralia on lobe tips. On calcareous rock.
Using the Wilk 2012 key to calcicolous Caloplaca of the Polish Carpathians, this keys to Caloplaca/Calogaya decipiens. Main features being soredia on lobe tips and/or in center of thallus concolorous with the thallus, and having a lobate thallus. Next closest would be Leproplaca cirrochroa, which has yellow soredia on the lobe bases and a more orange thallus, and often has lost the central parts of the thallus (which is typical of L. cirrochroa around here).

On ESE-facing exposed dry siliceous rock on upper third of slope. ID uncertain. Capitate soralia, lobes very tightly appressed, slightly convex, more regular and cracked and without maculae compared to Physcia caesia.

On exposed silecous rock on upper third of ESE-facing dry cliff. ID uncertain. Seems odd--pruinose, maculate, esorediate. Perhaps due to growing conditions, or some unusual species?

Growing on lower trunk of small Pinus banksiana in open, sandy mixed woodland. ID uncertain, but based on scrobiculate upper thallus with what seem to be a small amount of developing pseudocyphellae and soredia, and with rounded brownish lobe tips, but something about the upper surface seems odd, and also the black underside is definitely weird.

First state record discovered in May and collected July 30. Duplicates to be sent to University of Wisconsin, University of Michigan, and Michigan State University. Present on high hummocks throughout this peatland, but this collection from underneath spruces along a minerotrophic channel draining a large spring. Habitat shot & comparisons with C. trisperma in last 6 photos.

reticulately ridged upper surface, black lower surface, laminal soralia. K+y, KC-, C-, UV-. As far as I can tell, this is the first time this species has been observed in WI. The chemistry tests rule out other possibilities. On small tamarack branch, in tamarack bog.
