Order Desmothoracida, the desmothoracids, are a group of heliozoan protists, usually sessile and found in freshwater environments. The adult is a spherical cell around 10-20 μm in diameter surrounded by a perforated organic lorica, or shell, with many radial pseudopods projecting through the holes to capture food. These are supported by small bundles of microtubules that arise near a point on the nuclear membrane. Unlike other heliozoans, the microtubules are not in any regular geometric array, there does not appear to be a microtubule organizing center, and there is no distinction between the outer and inner cytoplasm.
Cheilanthes, commonly known as lip ferns, is a genus of about 180 species of rock-dwelling ferns with a cosmopolitan distribution in warm, dry, rocky regions, often growing in small crevices high up on cliffs. Most are small, sturdy and evergreen. The leaves, often densely covered in trichomes, spring directly from the rootstocks. Many of them are desert ferns, curling up during dry times and reviving with the coming of moisture. At the ends of veins sporangia, or spore-bearing structures, are protected by leaf margins, which curl over them.
Balantidium is a genus of ciliates. It contains the parasitic species Balantidium coli, the only known cause of balantidiasis.
Notholaena, cloak fern, is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae. Ferns of this genus are mostly epipetric or occurring in coarse, gravelly soils, and are most abundant and diverse in the mountain ranges of warm arid or semiarid regions. They typically have a creeping or erect rhizome and leaves that are pinnatifid to pinnate-pinnatifid with marginal sori protected by a false indusium formed from the reflexed margin of the leaf. Members of Notholaena also have a coating of whitish or yellowish farina on the surfaces of the leaves. The farina is often limited to the abaxial (lower) leaf surface, but may occur on the adaxial (upper) leaf surface as well. Members of the related Pentagramma genus have a similar lower leaf-surface farina.
Plagiogyria is a genus of ferns, the only genus in family Plagiogyriaceae in the Pteridophyte Phylogeny Group classification of 2016. Alternatively, the family may be treated as the subfamily Plagiogyrioideae of a very broadly defined family Cyatheaceae, the placement used for the genus in Plants of the World Online as of November 2019.
Trichomanes is a genus of ferns in the family Hymenophyllaceae, termed bristle ferns. The circumscription of the genus is disputed. All ferns in the genus are filmy ferns, with leaf tissue typically 2 cells thick. This thinness generally necessitates a permanently humid habitat, and makes the fronds somewhat translucent. Because of this membrane-like frond tissue, the plant is prone to drying out. “Filmy ferns” in the taxa Hymenophyllaceae grow in constantly wet environments. Many are found in cloud forests such as “Choco” in Colombia. There are also members of the taxa that can grow submersed in water.
Enterosora is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). PPG I also recognizes the genus Zygophlebia, which more recent sources include in Enterosora. As of February 2019, many do not have formally published names in Enterosora and are retained here in Zygophlebia.
Glossopappus is a genus of flowering plants in the daisy family.
Hymenolepis is a South African genus of flowering plants in the daisy family.
Hypolepis (beadfern) is a genus of ferns described as a genus in 1806. The word is derived from Greek, meaning "under scale". It is found in tropical and subtropical regions, primarily in the New World but also in the Old World and on various oceanic islands.
Onychium japonicum is a species of fern in the family Pteridaceae.
Pyrgacris is a small genus of grasshoppers in the monotypic family Pyrgacrididae. The two species in the genus Pyrgacris are found only on Reunion Island.
Polypodium is a genus of ferns in the family Polypodiaceae, subfamily Polypodioideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The genus is widely distributed throughout the world, with the highest species diversity in the tropics. The name is derived from Ancient Greek poly (πολύ) "many" + podion (πόδιον) "little foot", on account of the foot-like appearance of the rhizome and its branches. They are commonly called polypodies or rockcap ferns, but for many species unique vernacular names exist.
Myxotrichum chartarum is a psychrophilic and cellulolytic fungus first discovered in Germany by Gustav Kunze in 1823. Its classification has changed many times over its history to better reflect the information available at the time. Currently, M. chartarum is known to be an ascomycete surrounded by a gymnothecium composed of ornate spines and releases asexual ascospores. The presence of cellulolytic processes are common in fungi within the family Myxotrichaceae. M. chartarum is one of many Myxotrichum species known to degrade paper and paper products. Evidence of M. chartarum "red spot" mold formation, especially on old books, can be found globally. As a result, this fungal species and other cellulolytic molds are endangering old works of art and books. Currently, there is no evidence that suggests that species within the family Myxotrichaceae are pathogenic.
Cephalomanes atrovirens is a species of fern in the family Hymenophyllaceae. The genus Cephalomanes is accepted in the Pteridophyte Phylogeny Group classification of 2016, but not by some other sources. As of October 2019, Plants of the World Online sank the genus into a broadly defined Trichomanes, while treating the subtaxa of this species as the separate species Trichomanes acrosorum, Trichomanes atrovirens, Trichomanes boryanum and Trichomanes kingii.
Argyrochosma dealbata, the powdery false cloak fern, is a small fern endemic to the central and southern United States. It grows on calcareous rocks, such as limestone. Its leaves are highly divided, with leaf segments joined by shiny, chestnut-brown axes, and their undersides are coated with white powder, giving the fern its name. First described as a species in 1814, it was transferred to the new genus Argyrochosma in 1987, recognizing their distinctness from the "cloak ferns".
Arthrinium is a genus of minute disease-causing fungi which belong to the family Apiosporaceae and which are parasitic on flowering plants such as sedges. These fungi have an anamorphic life cycle stage where spores are produced asexually in structures called conidia and a teleomorphic stage where sexual spores are produced in asci.
Cephennium is a genus of beetles belonging to the family Staphylinidae.
Dothidea is a genus of fungi belonging to the family Dothideaceae. The genus was first described in 1818 by Elias Magnus Fries. The type species is Dothidea sambuci.
Leptothyrium is a genus of fungi belonging to the order Pleosporales, family unknown.
