Nyenyezi yovekedwa korona (Geastrum coronatum) chithunzi ndi kufotokozera

Crown starfish (Geastrum coronatum)

Nyenyezi yovekedwa korona (Ndi t. Geastrum yokhala ndi korona) ndi bowa wa banja lodziwika bwino la nyenyezi. Mwasayansi amatchedwa nyenyezi yapadziko lapansi. Mu bowa wakucha, chipolopolo chakunja cha thupi la fruiting chimang'ambika, chifukwa chake chimakhala ngati nyenyezi yaikulu yotsegulidwa. Pakati pa otola bowa, amatengedwa ngati bowa wosadyedwa ndipo samadyedwa.

Maonekedwe a starfish okhala ndi korona ndiachilendo kwambiri, omwe amasiyanitsa ndi bowa wamtundu wina ndi mabanja. Bowa amaonedwa kuti ndi wachibale wapamtima wa bowa wa puffball.

Matupi ozungulira a fruiting a bowa wamng'ono ali pansi pa nthaka. Mbali yakunja ya chipolopolo ikasweka pamene bowa akukula, nsonga zosongoka za bowa zimawonekera padziko lapansi. Amapaka utoto wotuwa wokhala ndi matte gloss. Pakati pa masambawa pali khosi lalitali la bowa, pomwe pali mpira wachipatso wofiirira wokhala ndi stomata pamwamba, womwe umatulutsa spores. Mbalame zozungulira za starfish ndi zofiirira zakuda. Mwendo, wachikhalidwe cha bowa onse, mulibe mumtundu uwu.

Maonekedwe, bowa ndi wofanana ndi nyenyezi ya bowa ya Shmarda (Geastrum smardae). Koma masamba ake a bowa wonyezimira amatha kuphulika.

Malo ogawa ndi nkhalango za gawo la ku Ulaya la Dziko Lathu ndi nkhalango zamapiri za North Caucasus. Amakula bwino m'nkhalango zomwe zili pamwamba pa nyanja.

Crown starfish imapezeka m'dzinja m'minda ndi m'mapaki pansi pa zitsamba ndi mitengo yophukira. Malo omwe amakonda kwambiri kukhazikika kwa bowa ndi dothi lamchenga ndi dongo, lomwe limakutidwa ndi udzu wochepa.

Chifukwa cha mawonekedwe ake osazolowereka komanso mawonekedwe ake osowa, ndizosangalatsa asayansi kwa akatswiri otola bowa.
