features

Macroscopic features

The stalked fruiting bodies , the apothecia , are up to 3.5 centimeters in size and up to 3 centimeters wide. They are bowl-shaped and yellow to ocher in color. The edge is entire and has the same color as the rest of the fruiting body. The stem is also yellow, is firm and rounded and is up to 2.2 centimeters long and 1-2 millimeters thick. The Chinese finds have a significantly shorter stem or are almost sessile. The fruit layer is smooth and the same color as the rest of the fruit body.

Microscopic features

The tubes are long and cylindrical, but at the base they become narrow to hyphae-shaped, at the top they are blunt, are thick-walled and each have 8 spores . The iodine color reaction is negative. They grow to be 300-370 × 14-16 micrometers in size. The spores are ellipsoidal, often unequal, with thickened walls at the poles, have fine longitudinal ribs that can run into one another or be branched at the tip. They grow to be 26.5–34.2 × 10–11.5 micrometers in size. They have three or more drops of oil. The outer excipulum is up to 44 micrometers thick and has a textura angularis , i.e. a parenchymal- like tissue. Hair emerges from this outer excipulum and reaches 80 microns.

Ecology and diffusion

Cookeina indica lives on dead, rotting branches in deciduous forests. It has so far been found in India (in West Kameng ) and in China in the provinces of Yunnan and Guizhou .

Systematics and taxonomy

Cookeina indica was first described in 1984 by Donald H. Pfister and Rishi Khausal . Phylogenetic studies proved that it belongs to the genus Cookeina , but no clear assignment could be made within the genus.

etymology

The name indica obviously refers to the first place of discovery in India. The generic name Cookeina honors the English mycologist Mordecai Cubitt Cooke .
