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.
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.
Tilletia is a genus of smut fungi in the Tilletiaceae family. Species in this genus are plant pathogens that affect various grasses. Tilletia indica, which causes Karnal bunt of wheat, and Tilletia horrida, responsible for rice kernel smut, are examples of species that affect economically important crops.
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.
The Venturiaceae are a family of fungi in the order Venturiales. Several of the species in this family are plant pathogens.
Phyllachoraceae is a family of sac fungi.
The Melanommataceae are a family of fungi in the order Pleosporales. Taxa are widespread in temperate and subtropical regions, and are saprobic on wood and bark.
Microthyrium is a genus of fungi in the Microthyriaceae family.
Pseudomeliola is a genus of fungi in the Hypocreales order. The relationship of this taxon to other taxa within the order is unknown, and it has not yet been placed with certainty into any family. Unchanged in 2020.
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.
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.
Coleroa is a genus of fungi belonging to the family Venturiaceae.
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.
Phyllachora leveilleana is a species of fungus, a member of the division Ascomycota, and was first described by Ferdinand Theissen and Hans Sydow in 1917. Phyllachora leveilleana belongs to the genus Phyllachora, and family Phyllachoraceae.
