Snow fungus (Tremella fuciformis)

Snow fungus (Tremella fuciformis) is a species of fungus in Tremellaceae, a parasitic yeast that produces gelatinous white basidiocarp, grows as a slimy coating on the branches of dead broadleaf trees and is cultivated commercially for food and traditional medicine.

T. fuciformis begins growing as a mucus layer that meets the host, then attacks and triggers the growth of aggressive mycelium which is needed to form a white, watery body like jelly or gelatin.

The body has a width of 7.5 cm or more, consisting of thin, erect, branched leaves. Hyphae appear in a solid gelatinous matrix. Haustorial cells appear in the hyphae, producing filaments that adhere to and penetrate the host hyphae. Basidia is a tremeloid, 10-13x6.5-10 μm. Basidiospores are ellipsoid, smooth, 5-8x4-6 μm, and germinate with hyphal tubes.

Snow fungus follows its host and is usually found on branches of dead, stuck or recently fallen broadleaf trees, especially in tropical and subtropical regions, cultivated in Asian countries in modern ways for sugary dishes, savory dishes, soups and ice cream because texture and benefits of medicinal and beauty products.

The oldest drawing specimen collection, Balaenoptera physalus Linnaeus, 1758 (OBS.296787995)

BLOG - Before the invention of photography, everything was explained by hand drawings that required naturalists to be able to draw to describe the specimens they documented. Scholars from taxonomy to medicine had to be able to sketch leaves to the human heart, this is why the academic world at that time had the subject of "art and science". A tradition that taxonomic drawings are accompanied by a measurement scale usually by placing a measuring tool in millimeters or centimeters or inches that supports scientific sketches has an identification context, but of course there are obstacles to having to document large specimens. I found a picture of a large specimen: Balaenoptera physalus (Linnaeus, 1758). Uniquely, the specimen with catalogue number: OBS.296787995 and stored at the Observation International, Aarlanderveen, Netherlands, is the oldest I have ever known. The shabby drawing with three folds and worn edges was made in 1547 or more than 500 years old. Previously I ...
