Dumontinia
Fruiting bodies of the commons anemones cup Lings on wood anemone, some with excavated sclerotia

Features
Macroscopic characteristics
The common anemones cup Ling is always near Anemone cup-shaped fruiting bodies ( apothecia ). They are medium to dark red-brown and 0.8-2 (-3 ) cm wide. The consistency is fragile, her 4-10 cm long handle is tough and resilient, often dark hairy in the lower part and often with Erdklümpchen and springs from a bulbous sclerotium. The latter is berindet black and white interior, is 15-40 mm long, 5-25 mm wide and is located mostly on the rhizomes of the host plant.
Microscopic characteristics
The cylindrical- clavate hoses ( asci ) measuring 120-170 × 8-11 microns. The smooth ascospores are hyaline, long - elliptical, usually filled with two oil droplets and measure 12-17 × 5.5-7 microns. The fungus has in the fruit layer ( hymenium ) threadlike sterile elements ( paraphyses ).
Art-/Gattungsabgrenzung
The most important differentiating factor for the closely related genus of Sklerotienbecherlinge ( Sclerotinia ) is the special structure of the Excipulums: The outer layer consists of cylindrical cells ( " Textura prismatica " ), the inner layer of a loose hyphal network, which is embedded in a gelatinous matrix. In addition, from the vile Sklerotienbecherling no side fruit shape is known.
Ecology and distribution
The common anemones peel fungus lives parasitically on different types of anemones, va on anemones, but also on the Yellow Anemone. It forms the fruiting bodies in early spring usually just before flowering its host plant. Due to the coarse overlying stem and the sclerotium up to 5 cm deep lying the fungus is associated with the emaciated from his parasitic mycelium and thereby transformed to black tubular membranes Erdkriechsprossen ( rhizomes ) of the infested wood anemone. Gerhardt him as not frequent. It is known from Central, Western and Northern Europe. But also from Japan finds are reported.
Name
The genus name honors the mycologist Kent P. Dumont. The specific epithet refers to the bulbous sclerotium.
System
Originally described by Bulliard as Peziza tuberosa, the anemone cup Ling has long been placed in the genus Sclerotinia, since it also forms sclerotia. The mycologist Linda Kohn presented but because of the design of the Excipulums to a separate genus. Von Holst -Jensen, a second type yet described, namely Dumontinia ulmariae that lives parasitically on meadowsweet. It proved belonging to Dumontinia wrong. The type is called valid Hyalopeziza millepunctata, from the family of Hylopezizaceae. The anemones peel fungus is therefore monotypic.
