Helicobasidium compactum

Helicobasidium compactum is a species of fungus in the family in the class of the ear lobe fungal relatives ( Auriculariaceae ) the Tremellomycetes. It is distributed throughout the tropics and in Europe. The fungus grows parasitically on the trunks, roots and bark of trees, shrubs and herbaceous plants, especially near ground level.

Features

Macroscopic characteristics

The fruiting bodies of Helicobasidium compactum appears as velvety felted carpet on the surface of its host. The fruiting bodies are purple, velvety - tomentose and resupinat. In its texture is reminiscent of rotting material. The hymenium is purple. Are often formed pink rhizomorphs that frame it on its edge. The fruit layer can often cover the entire surface of the host.

Microscopic characteristics

The hyphae of Helicobasidium compactum are roller-shaped and do not have buckles. Two-to four-cell Protobasidien form at their ends. The basidia are weakly inflected. The thin-walled, smooth and inamyloiden spores of Helicobasidium compactum are narrow ellipsoid and reach a size of 12 to 23.5 × 3.5-6 microns. The hyphae of the Subcuticulums are strong violet- brown.

Ecology

Helicobasidium compactum grows parasitically on saprobiontisch and flowering plants, especially on the stumps, roots and bark of trees, shrubs and herbs. In the tropics, a broad spectrum is used to host plants, such as coffee and tea bushes. In Europe, the type ash trees ( Fraxinus spp.), Hawthorns (Crataegus spp.) And blackthorn was on mortar lumps (Prunus spinosa) found.

Dissemination

Helicobasidium compactum was first discovered in Africa, Asia and America tropics. In the 1970s, the species was first found in the UK, and later in Germany and Switzerland.
