Features

Macroscopic characteristics

The vermilion Pustelpilz is a small, but easily more recognizable fungus. Its fruit body like small raspberries. They consist of several standing together, about 0.2-0.3 mm wide perithecia - the entire fruiting body measures about 2 mm. The color varies from vermilion ( hence the name ) to dark red. Often the type also forms a secondary fruit shape that is recognizable as pink to orange - red, shapeless pustules, called sporodochia. Both forms can occur simultaneously.

Microscopic characteristics

The cylindrical- clavate tubes measure 65-80 x 8-10 microns. Therein develop colorless, smooth and easy -septate spores. They are easily constricted and similar in shape to a sole. The dimensions are a length 15 to 25 and the width between 5 to 9 microns. The conidia of the secondary fruit shape have a narrow elliptical to cylindrical shape, straight or slightly curved and unseptiert. They are 5.2 to 7 × 1.9 to 2.7 microns in size.

Ecology, phenology and distribution

The vermilion Pustelpilz usually grows on dead branches with bark still. He has a broad host range and settled mostly maples, hornbeam and linden trees, but also on beech, rock pears, currants, black locust and horse chestnuts. The species is considered predominantly saprob, but it can sometimes trigger cancerous growths in living trees and shrubs. Since fungicides hardly any effect, wound closure means are recommended for cuts.

He is to be found throughout the year, the teleomorph especially in spring.

The species is widespread and occurs in Europe and North America.

System

The vermilion Pustelpilz was first described in 1791 by death as Sphaeria cinnabarina. Fries placed it in 1849 as the type species in the new genus Nectria. The secondary fruit shape was described by death as a separate species under the name Tubercularia vulgaris. Only Fries realized that it is one and the same way in both. Over 20 different varieties and forms have been described in addition to several synonyms, among other Nectria ribis on currant. Recent molecular biological studies have suggested the division of the collective species in four ways: According to the new classification among Nectria cinnabarina specimens with long -stalked Spordochien. Nectria asiatica growing in Asia and the sporodochia are stalked only briefly. Nectria dematiosa has only one ungestieltes sporodochium or even makes no addition to fruit shape from. Nectria nigrescens finally up to three times septate ascospores.
