Tuberous Dumontinia, wanda kuma aka sani da Dumontinia cone-dimbin yawa ko Dumontinia cone (tsohon suna Sclerotinia tuberous) karamin naman ruwan bazara ne mai siffar kofi wanda ke tsiro sosai a cikin gungu na anemone (Anemone).

Jikin 'ya'yan itace Siffar kofin, ƙarami, a kan dogon bakin ciki mai tsayi.

Kofin: Tsayi bai wuce 3 cm ba, diamita 2-3, har zuwa 4 cm. A farkon girma, yana kusan zagaye, tare da gefen mai lankwasa mai ƙarfi. Tare da girma, yana ɗaukar nau'i na kofi ko gilashin cognac tare da gefen dan kadan a ciki, sa'an nan kuma a hankali ya buɗe, gefen yana ko da dan kadan ya lankwasa waje. Calyx yawanci ana siffata da kyau.

Wurin ciki yana da 'ya'yan itace (hymenal), launin ruwan kasa, santsi, a kan "kasa" yana iya zama dan kadan mai ninki, baki.

Fuskar waje ba ta da kyau, santsi, launin ruwan kasa mai haske, matte.

kafa: da kyau bayyana, tsawo, har zuwa 10 cm tsawo, bakin ciki, game da 0,3 cm a diamita, m. Kusan gaba ɗaya nutsewa cikin ƙasa. Ba daidai ba, duk a cikin lanƙwasa mai zagaye. Dark, launin ruwan kasa-launin ruwan kasa, baƙar fata.

Idan ka haƙa ƙafar a hankali zuwa tushe, za a ga cewa sclerotium yana manne da tubers na tsire-tsire (anemone). Yayi kama da nodules baƙar fata, m, 1-2 (3) cm cikin girman.

spore foda: fari-rawaya.

Jayayya: mara launi, ellipsoid, santsi, 12-17 x 6-9 microns.

ɓangaren litattafan almara: sirara sosai, gagujewa, fari, mara kamshi da ɗanɗano.

Dumontinia pineal yana ba da 'ya'ya daga ƙarshen Afrilu zuwa ƙarshen Mayu a cikin gandun daji masu ban sha'awa da gauraye, a kan ƙasa, a cikin tudu, a cikin glades da gefen titi, koyaushe kusa da furannin Anemone. Yana girma a cikin ƙananan ƙungiyoyi, yana faruwa a ko'ina, sau da yawa, amma da wuya ya jawo hankalin masu daukar naman kaza.

Dumontinia sclerotium an kafa shi akan tubers na nau'ikan anemone daban-daban - ranunculus anemone, itacen oak anemone, anemone mai ganye uku, da wuya - spring chistyak.

Wakilan Sclerotinia suna cikin rukunin nazarin halittu na hemibiotrophs.

A cikin bazara, a lokacin furanni na tsire-tsire, iska ta tarwatsa fungal ascospores. Da zarar a kan stigma na pistil, su germinate. Inflorescences masu kamuwa da cuta sun juya launin ruwan kasa kuma sun mutu, kuma tushen da abin ya shafa ba sa 'ya'ya. Jigon naman gwari a hankali yana girma ƙasa da tushe kuma ya samar da spermatozoa a ƙarƙashin epidermis. Maniyyi suna karya ta cikin epidermis kuma suna bayyana a saman mai tushe a cikin nau'in ɗigon ruwa mai launin ruwan kasa ko Emerald slimy. Danshin ruwa-ruwa da kwari suna yada spermatozoa zuwa tushe mai mutuwa, inda sclerotia ya fara tasowa.

Dumontinia ana daukar naman kaza maras amfani. Babu bayanai kan guba.

Akwai nau'ikan namomin kaza da yawa waɗanda suke kama da Dumontia.

Don ingantacciyar ganewar Dumontinia tuberosa, idan ba ku da microscope a hannu, kuna buƙatar tono tushe zuwa ainihin tushe. Wannan shine kawai abin dogaro macrofeature. Idan muka tono dukan kafa kuma muka gano cewa sclerotium yana lullube tuber anemone, muna da dumontinia a gabanmu.

Ciboria amentacea (Ciboria amentacea)

Guda ɗaya ƙananan kofuna waɗanda ba a san su ba na beige, launin ruwan kasa-launin ruwan kasa. Amma Ciboria amementacea yana kan matsakaicin ƙarami fiye da Dumontinia tuberosa. Kuma babban bambanci zai kasance a bayyane idan kun tono tushen kafa. Ciboria amentacea (catkin) yana tsiro a kan alder catkins na bara, ba akan tushen tsire-tsire ba.

Akwai wasu nau'ikan Sclerotinia da yawa waɗanda suma suna girma daga sclerotia, amma ba sa parasitize tubers anemone.
