Lumpy bracket (Trametes gibbosa)

Lumpy bracket (Trametes gibbosa) is a species of fungus in the Polyporaceae, grows on dead wood and trees from other hardwood species, the fruit body has a diameter of 8-15 cm and is semicircular, the top surface is usually white or yellow or gray.

T. gibbosa starts out as a white, wax-like patch on the surface of the wood and grows into a semicircular slab. Fruit bodies widen by forming new plates and stacking vertically and horizontally.

The margins are thinner and getting to the base is getting thicker, the top surface is flat and is white or yellow or gray, the bottom surface is completely white with elongated, open pores and slightly translucent.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Cempaki (Termitomyces microcarpus)

Cempaki ( Termitomyces microcarpus ) is a species of fungus in the Lyophyllaceae family. It grows wild in tropical Asian forests near termite nests. It is rarely reported in urban areas. It is edible and known for its deliciousness, high nutritional value, and difficulty in cultivating. In Indonesia, it is used as an alternative food ingredient. T. microcarpus is the smallest of the Termitomyces species, umbrella-shaped, plain white, measuring 5 cm tall and 2.5 cm wide. It grows in dense clusters on surfaces and forms a mutualistic relationship, requiring the metabolic activity of termites as a substrate for growth. This species is known for its deliciousness, rich in nutrients, and has potential bioactive properties, such as helping lower cholesterol and acting as a tonic. Currently, it is difficult to cultivate on a large scale, and people rely solely on wild harvests. This mushroom is highly favored for its savory, delicious flavor and soft, chewy texture. It is often stir-fried ...

Oceanitis abyssalis, the deepest sea fungus at 5707 meters from sunken wood

NEWS - Researchers report a new species of deep-sea fungus, Oceanitis abyssalis , described based on SU rDNA sequence analysis and morphological characteristics. The specimen was found attached to a branch of Prunus sp. at a depth of 5707 meters on the abyssal plain in the Northwest Pacific Ocean, east of the Japanese Islands. This discovery is the deepest recorded for a marine fungus. Previous research by an international team in the Ocean Species Discoveries project reported 11 new species of ocean animals at a depth of 7000 meters . Oceanitis Kohlm (1977) grows on a variety of plant species in a variety of coastal to deep-sea environments. This genus is also widespread in geologically isolated deep-sea areas as one of the most successful fungal taxa in these environments. The thick peridium allows it to adapt to extreme deep-sea conditions. The morphology of O. abyssalis is very similar to O. scuticella Kohlmeyer, but O. abyssalis having unicellular ascospores, smaller deciduous...
