Qhov no nceb feem ntau kuj hu ua hauv paus daim txhuam cev.
Keeb kwm ntawm lub npe ntawm no nceb yog nthuav. Thawj thawj zaug, cov kab mob no tau piav qhia meej raws li lub hauv paus sponge rov qab rau xyoo 1821 thiab tau hu ua Polyporus annosum. Xyoo 1874, Theodor Hartig, uas yog German arborist, tau koom nrog cov kab mob no nrog cov kab mob ntawm cov hav zoov coniferous, yog li nws tau hloov nws lub npe Heterobasidion annosum. Nws yog lub npe tom kawg uas tau siv dav niaj hnub no los hais txog hom kab mob fungus.
Lub cev fruiting ntawm perennial heterobasidion hauv paus daim txhuam cev yog varied thiab feem ntau muaj ib tug tsis meej pem. Nws yog perennial. Daim ntawv yog qhov txawv tshaj plaws, ob leeg prostrate los yog prostrate-bent, thiab hoof-shaped thiab plhaub-puab.
Cov txiv hmab txiv ntoo lub cev yog 5 mus rau 15 cm thoob plaws thiab mus txog 3,5 mm tuab. Lub pob sab sauv ntawm cov fungus muaj ib tug concentrically striated nto thiab yog them nrog ib tug nyias crust, uas tshwm sim nyob rau hauv lub teeb xim av los yog chocolate xim av.
Heterobazidion perennial yog faib nyob rau hauv lub teb chaws ntawm North America thiab Eurasia. Cov kab mob fungus no yog kev lag luam tseem ceeb rau ntau hom ntoo - rau ntau tshaj 200 ntawm ntau hom coniferous thiab hardwood deciduous hom teej tug mus rau 31 genera.
Perennial heterobasidion tuaj yeem kis tau cov ntoo hauv qab no: fir, maple, larch, kua, ntoo thuv, spruce, poplar, pear, Oak, sequoia, hemlock. Nws yog feem ntau pom nyob rau hauv gymnospermous ntoo hom.
Qhov tseeb nthuav yog tias cov tshuaj uas muaj cov tshuaj tiv thaiv kab mob tau pom nyob rau hauv cov tshuaj muaj pes tsawg leeg ntawm perennial heterobasidion.
