Volkartia (Volkartia rhaetica)

Volkartia (lat. Volkartia rhaetica) ndi bowa wapadera. Ndi bowa lokhalo la mtundu wa Volkartia. Uwu ndi mtundu wa bowa wa ascomycete (banja la Protomycium). Bowawa nthawi zambiri amawononga zomera zamtundu wa Skerda.

Mtundu wa Volkartia unapezeka ndikugwiritsidwa ntchito ndi R. Mair kale mu 1909, koma kwa nthawi yayitali unali wofanana ndi mtundu wa Taphridium. Koma mu 1975, mtundu uwu (ndi bowa) unapangidwanso palokha ndi Reddy ndi Kramer. Pambuyo pake zinavomerezedwa kuti muphatikizepo mafangasi ena omwe kale anali a Taphridium.

Volkarthia imatengedwa kuti ndi tiziromboti. Bowa limayambitsa mawanga akuda pamasamba a chomera chomwe chakhudzidwa ndi Volcarthia. Bowa palokha nthawi zambiri amakhala mbali zonse za tsamba. Volkarthia ili ndi imvi-yoyera ndipo imakhala ndi gawo lalikulu latsamba la chomeracho.

Mawu ochepa okhudza kapangidwe ka mkati mwa bowa.

Ma cell a Ascogenous amapanga gulu la cell kwambiri pansi pa epidermis. Nthawi zambiri amakhala ozungulira, kukula kwake ndi 20-30 microns. Iwo amakula ngati synasci, palibe matalala nthawi. Ndi mawonekedwe a synascos omwe ndi mawonekedwe apadera omwe amatilola kuti tilekanitse Volkarthia ndi bowa wamtundu wa Tafridium. Malo a maselo a ascogenous akhoza kuonedwa ngati kusiyana pakati pa bowa ndi oimira protomyces, momwe maselo omwe ali pansi pa epidermis amabalalika. Zitha kuwonjezeredwa kuti mu protomyces, mapangidwe a synasces amachitika pakatha nthawi yopuma. Ngati tilankhula za ma synasces, ndiye kuti ku Volcarthia ndi ma cylindrical, kukula kwawo ndi pafupifupi 44-20 µm, makulidwe a chipolopolo chopanda utoto ndi pafupifupi 1,5-2 µm.

Ma spores, monga chipolopolo, alibe mtundu, 2,5-2 µm kukula kwake, ozungulira kapena owoneka ngati ellipsoidal, amatha kukhala owongoka kapena opindika. Ascospores nthawi zambiri amapangidwa kale pa ascogenous cell siteji. Ma spores amayamba kukula mycelium nthawi yogona ikatha.

Bowawa nthawi zambiri amawononga Crepis blattarioides kapena mitundu ina yofananira ya skerda.

Bowa limapezeka ku Germany, France, Switzerland ndi Finland, komanso limapezeka ku Altai.
