Cookeina sinensis is a hose fungus from the family of the cup-cup relatives .
features
Macroscopic features
The stalked, individually standing bowl-shaped fruiting bodies , the apothecia , are up to 2.5 centimeters in size and up to 5 centimeters wide. The fruit layer is ocher-orange to coarse earth-colored. The receptacle is yellow-brown to cinnamon-brown when dry. It's clearly hairy. These hairs are stiff, bristly, 6-7 millimeters long, arranged in tufts and arise from the medullary excipulum .
Microscopic features
The outer excipulum is up to 50 micrometers thick, has a textura angularis (a parenchymal- like tissue) with thick-walled, translucent cells that are 7-13 × 15-25 micrometers in size. The medullary excipulum consists of a textura intricata (a tissue of filamentous, strongly interwoven hyphae ) that is 230-300 micrometers thick. The tubes are suboperculate , long cylindrical, but are hyphae-shaped at the base, are thick-walled and each have 8 spores . The iodine color reaction with Melzer's reagent is negative. They will be 280-290 × 16-17 micrometers in size. The spores are smooth, almost spindle-shaped to lemon-shaped. They will be 25-28 × 12-12.5 microns in size. They have two oil droplets that can be up to 9 micrometers in diameter. The paraphyses are pearl-like (moniliform), with cross connections ( anastomosing ) and septate .
Species delimitation
Cookeina sinensis differs from Cookeina colensoi by the long stems, the non-gelatinous excipulum and the large apothecia and the presence of hairs. Cookeina sinensis differs from Cookeina tricholoma by the smooth spores and the other paraphyses. The species Cookeina korfii , described in 2015, has smaller spores and so far (2016) is only known from the Philippines.
Ecology and diffusion
Cookeina sinensis lives on dead, rotting branches and vegetable waste. It was initially only found in China including Taiwan. In the meantime, finds from India from the state of Maharashtra are also known. The holotype is from Yunnan Province .
Systematics and taxonomy
Cookeina sinensis was first described in 1997 by the Chinese mycologist Zheng Wang . Phylogenetic studies showed that it is the sister species to Cookeina tricholoma , but it differs significantly from it. The species Cookeina korfii , described in 2015, is also in this clade.
etymology
The name sinensis obviously refers to the first place of discovery in China. The generic name Cookeina honors the English mycologist Mordecai Cubitt Cooke .
