Biscogniauxia nummularia decline of European beech ("Fagus sylvatica") in Sicily and Calabria (Italy) has been linked to "B. nummularia" and experiments have suggested that this ascomycete plays a primary pathogenic role under certain environmental conditions. It typically causes strip‐cankering and general wood decay. Biscogniauxia nummularia Biscogniauxia nummularia is a plant pathogen in the family Xylariaceae, known as the beech tarcrust. The specific epithet is derived from the Latin "nummus" meaning a coin, referring to the often rounded and coin-like encrustations. The fruit body forms a thick and shiny black crust, on beech ("Fagus") bark and is found at all times of the
Microseris sylvatica containing up to 70 yellow ray florets. The fruit is an achene with a pale body up to a centimeter long. At the tip of the body is a large pappus made up of several long, barbed, bristly scales each up to a centimeter in length themselves. Microseris sylvatica Microseris sylvatica is a species of flowering plant in the aster family known by the common names sylvan scorzonella and woodland silverpuffs. It is endemic to California, where it has a scattered distribution throughout the central California Coast Ranges and inland mountain ranges, including the Sierra Nevada of the state. Its
