Sebutan jamur kuping melekat pada jenis jamur yang memiliki tubuh buah basadio-carp mirip kuping daun telinga. Jamur merupakan Kingdom Fungi , dengan karakter Heterotrop karena tidak memiliki khlorofil. Jamur memiliki inti, berspora, dan merupakan sel-sel lepas atau bersambungan membentuk benang Hifa Hifa jamur kuping ini bersekat Hifa jamur membentuk kelompok yang disebut miselium kumpulan hifa. Miselium jamur ini bercabang-cabang dan pada titik-titik pertemuannya membentuk bintik kecil yang disebut sporangium yang akan tumbuh menjadi pin head tunas atau calon tubuh buah jamur Pin head akhirnya berkembang tumbuh menjadi jamur tubuh buah. Tubuh jamur kuping bertangkai pendek dan tumbuh menempel pada substrat dengan membuat lubang pada permukaannya.

Corresponding author. This article has been cited by other articles in PMC. Abstract A new disease, the slippery scar, was investigated in cultivated bags of Auricularia polytricha. This fungus was isolated from the infected mycelia of cultivated bags. Based on morphological observation, rDNA-internal transcribed spacer and 18S sequence analysis, this pathogen was identified as the Ascomycete Scytalidium lignicola.
The parasitism of this fungus on mushroom mycelia in China has not been reported before. It has special flavors, improves sexual function, clears away lung heat, activates the blood, alleviates pain, and so on.
Recent medical studies show that the fruitbody of A. In May , a new disease called the slippery scar by the local inhabitants of Shifang, Pengzhou, and Guanghan cities in Sichuan Province was found.
Finally, the yield of A. Materials and Methods Isolates collection The pathogen was isolated from cultivated bags collected in Shifang City, purified, cultured, and preserved. The tested cultivated variety of A. Pathogen isolation From to , the symptom, status, and occurrence of the slippery scar disease was surveyed, observed, and recorded in Shifang, Pengzhou, and Guanghan cities, Sichuan Province. Conventional tissue isolation was carried out.
The infected mycelia of A. Finally, the colony was purified and inoculated for further research. Bagging, sterilization, and inoculation were performed according to the report of Zhang [ 2 ]. Two programs were used in the pathogenicity test. One program involved the simultaneous inoculation of the mycelia of A. The other involved the inoculation of A. The mycelia of the isolated colony were then inoculated onto the surface of mycelia when A.
Culture characteristics of the re-ioslation were observed to see if they were the same as the inoculation. At last the re-isolation and the inoculation were co-cultured to see if there were antagonistic lines. Culture characteristics The screening test for the optimal culture conditions, such as temperature, pH, as well as C and N sources, was performed according to Li et al. The products were purified and sequenced by Genscript Company Nanjing, China. Results Symptoms and development The pathogen only infected the mycelia of A.
This feature is the outstanding characteristic of the slippery scar disease. Slippery, glossy, and dark-brown scars formed on the surface of infected mycelia of A. There was a red-brown antagonistic line between the infected and healthy mycelia, and the margin of this line was irregular. The infected scar extended rapidly until it ran across the full bag. When the mycelia of A. Pathogen infection thoroughly corroded the mycelia. Sometimes, the pathogen infected and swallowed all mycelia of full cultivation bags of A.

Cloud ear fungus
Sporocarps of Auricularia grow mainly on the stems and stumps of deciduous trees maples, oaks, ash tree, European elder and form clusters. It can be found throughout the year, even in winter, unless the winter is particularly cruel. Auricularia received its name according to its shape and consistency, as it resembles the human ear or earlobe. The colour of sporocarps is in different shades of brown. Auricularia is very often added to Asian dishes. Notes documenting the use of Auricularia and its targeted cultivation, date back to AD. These are documents describing its targeted cultivation from AD.
