Tricholoma primulibrunneum is an agaric fungus of the genus Tricholoma. Found in Sabah, Malaysia, where it grows on humus in Agathis forest, it was described as new to science in 1994 by English mycologist E.J.H. Corner.[1]
Description
[edit]Like other members of the genus Tricholoma, T. primulibrunneum produces mushrooms with white spore prints and gills that are attached to the stem, often by means of a slight notch (sinuate attachment).[2] Under the microscope, it has inamyloid spores, which is characteristic of the genus.[3]
While detailed morphological descriptions of T. primulibrunneum are limited in accessible scientific literature, it belongs to a genus characterized by:
- Fleshy, often robust mushrooms
- White spore prints
- Gills that are typically attached to the stem
- Absence of both a partial veil and a volva in mature specimens[4]
Distribution and Habitat
[edit]Tricholoma primulibrunneum is found in Sabah, Malaysian Borneo, where it grows on humus in Agathis forests.[5] Agathis borneensis, commonly known as "dammar minyak" in Malay, is a lightweight softwood tree belonging to the family Araucariaceae that forms a significant component of certain forest ecosystems in Malaysia.[6]
The fungus likely has an ectomycorrhizal relationship with Agathis borneensis trees, similar to other Tricholoma species which form symbiotic relationships with various coniferous or broad-leaved trees.[7] In these relationships, the fungus helps the tree absorb nutrients and water while receiving carbohydrates from the tree through photosynthesis.
Ecology
[edit]The broader ecological role of T. primulibrunneum in the Agathis forest ecosystem of Sabah has not been extensively documented in accessible scientific literature. However, as an ectomycorrhizal fungus, it likely plays an important role in forest health and nutrient cycling.
Agathis forests in Borneo are characterized by sandy, sometimes peaty soils, and can range from lowland to lower montane elevations.[8] These forests have faced significant threats from logging and habitat conversion, which may impact the distribution and abundance of associated fungi, including T. primulibrunneum.
