Leptosphaeria acuta (also known as nettle rash) is a plant pathogen found on the dead stems of common nettle ( Urtica dioica ). [1]
Urtica dioica, often known as common nettle, burn nettle, stinging nettle or nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, it is now found worldwide. The species is divided into six subspecies, five of which have many hollow stinging hairs called trichomes on the leaves and stems, which act like hypodermic needles, injecting histamine and other chemicals that produce a stinging sensation upon contact.
A plant canker is a small area of dead tissue, which grows slowly, often over years. Some cankers are of only minor consequence, but others are ultimately lethal and therefore can have major economic implications for agriculture and horticulture. Their causes include a wide range of organisms as fungi, bacteria, mycoplasmas and viruses. The majority of canker-causing organisms are bound to a unique host species or genus, but a few will attack other plants. Weather and animal damage can also cause stress to the plant resulting in cankers. Other causes of cankers is pruning when the bark is wet or using un-sterilized tools.
Nettle agents or urticants are a variety of chemical warfare agents that produce corrosive skin and tissue injury upon contact, resulting in erythema, urticaria, intense itching, and a hive-like rash.

Chrysaora is a genus of jellyfish, commonly called the sea nettles, in the family Pelagiidae. The origin of the genus name Chrysaora lies in Greek mythology with Chrysaor, brother of Pegasus and son of Poseidon and Medusa. Translated, Chrysaor means "he who has a golden armament."
Leptosphaeria maculans is a fungal pathogen of the phylum Ascomycota that is the causal agent of blackleg disease on Brassica crops. Its genome has been sequenced, and L. maculans is a well-studied model phytopathogenic fungus. Symptoms of blackleg generally include basal stem cankers, small grey lesions on leaves, and root rot. The major yield loss is due to stem canker. The fungus is dispersed by the wind as ascospores or rain splash in the case of the conidia. L. maculans grows best in wet conditions and a temperature range of 5–20 degrees Celsius. Rotation of crops, removal of stubble, application of fungicide, and crop resistance are all used to manage blackleg. The fungus is an important pathogen of Brassica napus (canola) crops.
Physella acuta is a species of small, left-handed or sinistral, air-breathing freshwater snail, an aquatic gastropod mollusk in the family Physidae. Common names include European physa, tadpole snail, bladder snail, and acute bladder snail. In addition, Physa acuta, Physa heterostropha and Physa integra are synonyms of Physella acuta.
Leptosphaeria coniothyrium is a plant pathogen. It can be found around the world.
Leptosphaeria pratensis is a plant pathogen. It causes stagonospora root rot.
Leptosphaeria sacchari is a plant pathogenic fungus which causes a disease called ring spot on Saccharum officinarum. This species was originally described in 1890 by Kruger and in 1892 by Van Breda de Haan after it was discovered in the Dominican Republic. L. sacchari is the applied name, whereas Epicoccum sorghinum is the accepted name.
Leptosphaeria cannabina is a plant pathogen.
Leptosphaeria woroninii is a plant pathogen.
Carex acuta, the acute sedge, slender tufted-sedge, or slim sedge, can be found growing on the margins of rivers and lakes in the Palaearctic terrestrial ecoregions in beds of wet, alkaline or slightly acid depressions with mineral soil.
