Omphalotrigonotis

Omphalotrigonotis is a genus of fungi in the family Omphalotaceae. The genus contains a single species, Omphalotrigonotis oregonensis, which is found in the Pacific Northwest region of North America.

Taxonomy

The genus Omphalotrigonotis was first described by American mycologist Alexander H. Smith in 1949. The genus name combines Omphalotus, another genus of fungi in the family Omphalotaceae, with trigonotis, derived from the Greek words for "three" and "angle", referring to the triangular shape of the spores. The species epithet oregonensis refers to the state of Oregon, where the type specimen was collected.

Description

The fruit bodies of Omphalotrigonotis oregonensis are mushrooms with a cap up to 3 cm (1.2 in) in diameter, and a stem up to 5 cm (2.0 in) long. The cap is convex to flat, and orange to brown in color. The gills are decurrent, running down the stem, and are white to cream in color. The spores are triangular in shape, a characteristic feature of the genus.

Distribution and habitat

Omphalotrigonotis oregonensis is found in the Pacific Northwest region of North America, including the states of Oregon and Washington. It grows in coniferous forests, particularly in areas with a high amount of rainfall.
