Mollisia

Mollisia cinerea

The Weichbecherchen ( Mollisia ) is a fungal genus in the family Dermateaceae. In Europe, more than 50 species occur. The species live as saprophytes on dead wood or other plant debris.

Features

These stemless Discomycetes have a size of about 0.2 to 4 millimeters (rarely up to 7 mm) and are soft fleshy. The cells of the ectalen (outer) Excipulums are brown, rarely colorless, and usually round, rarely prismatic. Very often in this genre refractive Vakuoleninhalte present in the paraphyses, which may solve relevant specifications with 3 -percent KOH yellow into the medium.

Determination

Macroscopically are usually unable to determine the different types, because many species are observed with the naked eye, indistinguishable from each other. To make matters worse is that most species are very variable in color depending on the age and moisture condition. So often four colors are necessary for the same type in order to grasp the cup somewhat into words. Determination are relevant, among other things in addition to the macroscopic appearance and substrate, the size and shape of the individual microscopic elements ( spores, asci, paraphyses, Excipulumzellen and end cells or hair ), the ascus pore reaction with Lugol (blue, red or negative), the mentioned KOH reaction of the Paraphyseninhaltes and the size and quantity of the oil droplets in the vital spores.

Many of the discovered species of this difficult genus can not be safely assigned to a described species. So many provisionally collection types are assigned, such as Mollisia cinerea.
