“…Arthur [15,16] placed Skierka in a separate subfamily or tribe, respectively, in the Pucciniaceae; while Cummins and Hiratsuka [1] treated it as incertae sedis within the rusts. Mains [20] hypothesized that Skierka represented an intermediate taxon between Melampsoraceae and Pucciniaceae (equivalent to the subordinate ranks Melampsorineae and Raveneliineae/Uredinineae, under the present classification). However, with the incorporation of DNA-based molecular studies in addition to basic morpho-taxonomy, this genus has now gained a definite placement in the order Pucciniales.…”

“…It seems evident that Skierka represents a distinct line of development and should be placed in a tribe Skierkeae by itself. The species of Skierka are observed to be tropical and autoecious [1,20], producing sub-epidermal and deep-seated; non-catenulate teliospores that extruded in hair-like columns. Although other researchers placed Skierka in a separate subfamily or tribe, Mains [20] considered it an intermediate taxon between Melampsoraceae and Pucciniaceae.…”

“…The spore mass typically pushes out of the telium as a thread or column. The rust disease symptoms are generally observed on mature leaves [6,20,30,46]. The rust sori formed by the fungus are amphigenous showing small, yellow or pale brownish, scattered, loosely aggregated or arranged in a circle, round, minute (0.1-0.4 mm diam.…”

The rust genus Skierka belonging to the phylum Basidiomycota was described in 1900 by Raciborski with Skierka canarii as the type species. The published literature on this rust genus reveals its ambiguity in taxonomic placement. It was challenging to taxonomically delineate and precisely identify each species within this genus due to the species sharing some common characteristics. The latest studies based on morphology taxonomy and molecular characteristics, however, have solved this puzzle now and placed this genus in its new family Skierkaceae. To understand all about the genus Skierka, this compilation was carried out to unveil the general characteristics, history, diversity, distribution, ecology, morphology and molecular taxonomy of different species of Skierka. After exploring 14 species of Skierka, it was observed that this genus is distributed in seven plant families in 19 countries all over the world. The genus appears to be well-represented in Asian and South American counties. This rust has not been reported from any European countries to date. The morpho-taxonomy of all species is well studied, but molecular analyses are still required. Only two species of the genus namely S. robusta and S. diploglottidis were identified based molecular analyses. Therefore, further studies should be focused on epitypifying the taxa that are too old and updating their taxonomy based on molecular, biochemical, and physiological aspects along with morphological characteristics. Multiple analytical methods should be considered when dealing with multi-locus datasets. This will increase our understanding of the diversity, distribution, and identification of these rust fungi.
