Astronomer (1839-1919).

Gustav Niessl von Mayendorf (26 April 1839 in Verona – 1 September 1919 in Hütteldorf, Vienna; often cited as G. von Niessl), was an astronomer and mycologist from Austria-Hungary. Niessl developed interests in botany, astronomy, and mathematics from a young age. His academic career began in 1859 as an assistant professor at the polytechnic institute in Brno, where he later became a full professor and served as rector (1877–1878). As an astronomer, he conducted research on meteor orbits that earned him membership in the Austrian Academy of Sciences, while his mycological work focused on micro

Uromyces dianthi (Carnation Rust) (Pers.) Niessl 1872
fungi species in the pucciniaceae family
Uromyces dianthi is a fungus species and plant pathogen infecting carnations and Euphorbia. It was originally published as Uredo dianthi by mycologist Christiaan Hendrik Persoon in 1801, before it was transferred to the Uromyces genus in 1872 by Gustav Niessl von Mayendorf. It is known as Carnation rust, it appears as an irregular shaped yellowing of the leaf and stem. These shapes then becomes elongated, with raised brown pustules on the underside of leaves from which brown dust (the fungal spores) are emitted when rubbed. It can be spread by wind currents (infecting leaves through the
Physalospora Niessl 1876
fungi genus in the hyponectriaceae family
Physalospora is a genus of fungi in the family Hyponectriaceae. The genus is estimated to contain about 36 species that grow on dead leaves. Often confused with Botryosphaeria, Physalospora is probably polyphyletic.

Podospora appendiculata (Auersw.) Niessl 1883
fungi species in the podosporaceae family
Podospora appendiculata is a coprophilous fungus that is most commonly found in the dung of lagomorphs, such as hares and rabbits, in temperate to warm climates. A member of the division Ascomycota, P. appendiculata is characterized by ovoid, hair-studded perithecia which can bear a distinctive violaceous colouring and peridia which are leathery, in texture. Podospora appendiculata produces three secondary metabolites (appenolides) with antimicrobial properties.

Melanopsamma is a genus of fungi within the Niessliaceae family. The genus contains 41 species.
Leptosphaeria libanotis (Fuckel) Niessl 1876
fungi species in the leptosphaeriaceae family
Leptosphaeria libanotis is a plant pathogen found mainly in Europe. It is the teleomorph stage of the fungus Phoma rostrupii.
Kalmusia Niessl 1872
fungi genus in the didymosphaeriaceae family
Kalmusia is a genus of fungi in the family Didymosphaeriaceae. The genus was formerly placed in family Montagnulaceae, before that was dissolved. The widespread, genus was estimated to contain about 12 species in 2008, which has increased to 29 species in 2023. The genus name of Kalmusia is in honour of Jakub Kalmus (1834 - 1870), who was a Bohemian doctor and Cryptogam researcher, who was a friend of the plant author. The genus was circumscribed by Gustav Niessl von Mayendorf in Verh. Naturf. Vereins Brünn vol.10 on page 204 in 1872.
Ceratosphaeria Niessl 1876
fungi genus in the ceratosphaeriaceae family
Ceratosphaeria is a genus of fungi in the Sordariomycetes class (subclass Sordariomycetidae) of the Ascomycota. The relationship of this taxon to other taxa within the class is unknown (incertae sedis), and it has not yet been placed with certainty into any order or family. The widespread genus contains 11 species.

Podospora anserina (Rabenh.) Niessl 1883
fungi species in the podosporaceae family
Podospora anserina is a filamentous ascomycete fungus from the order Sordariales. It is considered a model organism for the study of molecular biology of senescence (aging), prions, sexual reproduction, and meiotic drive. It has an obligate sexual and pseudohomothallic life cycle. It is a non-pathogenic coprophilous fungus that colonizes the dung of herbivorous animals such as horses, rabbits, cows and sheep.
