The blades of C. FRAGILIS are at least twice as long as they are wide. Gymnocarpium dryopteris has a triangular blade, but it is somewhat wider than it is long, and the sorus lacks an indusium. Dryopteris austriaca has blades that are over 20 cm long.
Associations in Sarmatic Mixed Forests
Other understory associates to Mountain Bladderfern (Cystopteris montana) in the Sarmatic forests include the widespread Western Brackenfern (Pteridium aquilinum). Common mosses found in the more mesic soils are Broom Forkmoss (Dicranum scoparium), Stairstep Moss (Hylocomium splendens), Red-stemmed Feathermoss (Pleurozium schreberi), Ostrich Plume (Ptilium crista-castrensis) and Common Hair Moss (Polytrichum commune).
Example wildflowers or forbs seen in the forest understory are: Marsh Helleborine (Epipactis palustris), Red Silene dioica), Sand Catchfly (Silene conica), White Silene latifolia), Common Spotted Orchid (Dactylorhiza fuchsii) and Field Scabious (Knautia arvensis). In some fens within forest clearings the Marsh thistle (Cirsium palustre) is found.

Cystopteris montana is a species of fern known by the common name mountain bladderfern. It occurs throughout the high latitudes of the Northern Hemisphere, in Eurasia, Greenland, and Alaska, and throughout Canada. It is also present in the higher elevations in Colorado farther south.
This fern produces a creeping, cordlike, scaly stem. The leaves are up to 45 centimeters long. The blades are borne on a petiole with a dark base and a light-colored end. The petiole is longer than the blade. The blade is pentagonal in shape and divided into leaflets which are subdivided into many lobed and toothed segments. The sori are covered in hairy, whitish, cup-shaped indusia.
This fern grows in moist mountain habitat, such as forests near streams.
