Description
 
 

Epichloë is a genus of fungus that infects grasses. The 35 species within the genus are classified into three types. Types II and III are mutualistic, providing benefits to the host. Type I is pathogenic, causing grass choke disease. Most Epichloë species coevolved with and infects just a single genus of grass plants. Epichloë typhina is the only species that infects many genera of cool season grasses, and is given the common name Choke Disease of Grasses.

In Choke Disease of Grasses, the fungus forms a cylindrical mass around the inflorescence, preventing the panicle from emerging, whch makes the plant sterile. The cushion-like mass is white at first, eventually turning yellow then brown.

Mufka źdźbłowa (Epichloë typhina)

06.06.2021

Wzgórza Krzesławickie

Archiwum własne

Niejadalny grzyb, pasożyt traw występujący najczęściej na źdźbłach kubkówki pospolitej (grzyb na źdźbłach trawy) i wiechliny gajowej. Można go spotkać późną wiosną i wczesnym latem. Grzybek koloru srebrzystobiałego na początku poprzez żółtawy do pomarańczowego. Można też go spotkać pod nazwą pochewczak pałkowaty traw.

Wybaczcie jakość nagrania i to że znów nic nie mówię, ale... sprzęt (kamerka, telefon, telefon z lupką) jaki jest taki jest i ciężko skupić się na czymś tak małym, a co do opowiadania – no cóż, nie potrafię, nie chce... lepiej jak sam obraz jest na nagraniach, bez dźwięku :-)

Krótki opis jest – to się liczy.

Google Translate: An inedible fungus, a grass parasite that occurs most often on the blades of the common cupcap (fungus on the blades of grass) and game panicle. It can be found in late spring and early summer. A silvery-white mushroom at first through yellowish to orange. It can also be found under the name of grass sheath.

Forgive the quality of the recording and the fact that I don't say anything again, but ... the equipment (webcam, telephone, phone with a magnifying glass) as it is and it's hard to focus on something so small, and as for the story - well, I can't, no I want ... better as the image itself is on the recordings, without sound :-)

The short description is - that's what counts
