Thupi laling'ono la fruiting ndi lozungulira, lofanana ndi peyala kapena bulbous, 4-7 masentimita mu kukula, ndi spout lakuthwa mpaka 2 cm, mtundu kuchokera kuyera mpaka bulauni. Exoperidium (chipolopolo chakunja) chosakanikirana ndi endoperidium (chipolopolo chamkati). Chofunikira kwambiri ndikuwonongeka kwa endoperidium panthawi yakukhwima, chifukwa chake gleba imawonekera kwathunthu. Imatha kukula pansi ndikutuluka pang'ono pamwamba. Zikakhwima, chipolopolo chakunja chimasweka ngati nyenyezi kukhala 4-6 (5-7) lobes (pali malipoti a 14 lobes), kufalikira panthaka kapena kukweza bulu wozungulira pamwamba pa nthaka.
Mofanana ndi raincoat yaikulu, imatha kutchulidwa ngati mitundu ya "meteor".
Zamkati poyamba ndi wandiweyani, wopangidwa capillium ndi spores, pamene kucha, ulusi pang'ono, powdery, woderapo. Capillium (ulusi woonda) amalimbikitsa kumasuka kwa spore mass, ndipo hygroscopicity yake imayambitsa kusuntha ndikulimbikitsa kupopera mbewu mankhwalawa.
HABITAT
Bowa amamera m'nthaka ya humus m'nkhalango zodula mitengo, malamba a nkhalango a mapulo, phulusa, dzombe la uchi, m'mapaki ankhalango, ndi m'minda. Sizipezeka kawirikawiri kapena kawirikawiri m'madera omwe kuli nyengo yofunda, m'malo osowa kwambiri, m'mapaki ndi m'minda, nthawi zambiri m'nkhalango za coniferous. Amapezeka m'nkhalango za ku Ulaya, komanso m'nkhalango zamapiri za ku Central Asia. Dziwani kuti mtundu uwu sunagawidwe kutali kumpoto. Kumadzulo kwa Ulaya, amadziwika ku Hungary, Germany, Austria, Switzerland. M'chigawo cha ku Ulaya cha Dziko Lathu, imapita kumpoto osati kutali ndi dera la Moscow. Mawonedwe ndi osowa.
MITUNDU OFANANA
Chifukwa cha kukula kwakukulu, mpira wamaliseche, waubweya wa gawo la fruiting, lomwe, likakhwima, silinavekedwe mkati mwa chipolopolo, nyenyezi yapadziko lapansi yakuda sungasokonezedwe ndi mitundu ina ya nyenyezi zapadziko lapansi.
