Suggested genus: Auricularia 木耳. Characteristics: ear-shaped friutbody, smooth hymenial surface Mainly found on dead wood, some species with abhymenial hair (Found on a decaying wood on grassland in CUHK near the University MTR station. Photo taken on 6 Nov.)
Nice picture! How can you tell if it is the Auricularia species, when there are so many jelly fungus species? You may suggest that it may be this species, if you are not very confirmed.
Please add at least one tag to your photo.
Thanks for your input and addition of extra information.
Jelly fungi are a part of subphylum Agaricomycotina and is a hymenomycete which means it produces spore externally. It has 4 orders- Tremellales, Auriculariales, Dacrymycetales and Sebacinales.
Jelly fungi have gelatin like consistency because the texture of the structural hyphae of these fungi have walls that are not thin or rigid as most fungi but are instead expanded out to a rather diffuse and indefinite extent. During dry periods, jelly fungi hyphae collapse down and become hard and resistant to bending but as soon as they come in contact with moisture, they expand back to their original gelatinous structure. Therefore, they are able to exist in dry environment for many months and when in contact with moisture, return to their original self. They may be among the earliest fungi to be seen in spring because they have remained dry all winter only to revive with the first melting of snow or during winter thaws.
