Peach tree infested by Taphrina deformans

Taphrina species are parasitic fungi on ferns and dicotyledonous higher plants thatare strictlyboundto their hosts . The host tissue is not killed, however, butstimulatedto the formation of hypertrophy ( fool's pockets ), deformations ( curl disease ) and witch's broom .

features

They have a haploid yeast stage , during which they feed saprophobically , and an ascus-forming dikaryophase that takes place exclusively on the host. Fruit bodies ( Ascomata ) are never formed, but their asci break out between the epidermal cells and form a coherent hymenium on the surface of the host. You always have eight spurs. In many species they are also filled with conidia that are pinched off by the spores. In some species, a so-called basal cell is formed by cross-connections in the lower part of the asci.

Taphrina species can cause very different clinical pictures:

• Leaf curl
• Witch's broom on branches
• Hypertrophy on fruits ( fool's pockets )

species

A total of about 100 species are known, of which about 30 are in Europe.

Due to the strict host bond, the species are classified according to the host:

• Taphrina filicina : At Karthäuserfarn
• Taphrina hiratsúkae : An ostrich fern

• Taphrina johansonii : On trembling aspen
• Taphrina rhizophora : On white poplar
• Taphrina populina : on black poplar

• Taphrina carpini : witch's broom on hornbeams

• Taphrina caerulescens : Forms blue-green leaf spots on various oaks

• Taphrina ulmi : Forms small spots and bumps on the leaves of elms

• Taphrina crataegi : causes adhesions on the shoots as well as a reddish curl of the leaves on hawthorn
• Taphrina bullata : Forms small, initially yellow-green, later blackened vesicular growths on pears
• Taphrina tormentillae : Forms yellowish growths on leaves and stems of cinquefoil , especially tormentil .

• Taphrina pruni : Forms fool's pockets on plum and sloe
• Taphrina padi : fool's pockets on common bird cherry
• Taphrina deformans : curl disease in peach , nectarine and apricot
• Taphrina wiesneri : Forms witch brooms on sour cherries and bird cherries
• Taphrina insititiae : adhesions on shoots on plum and sloe

• Taphrina acerina : witch's broom on Norway maple

  • Taphrina nana
  • Taphrina alpina
  • Taphrina lapponica
  • Taphrina betulina
  • Taphrina turgida
  • Taphrina betulae
  • Taphrina autumnalis
