Zugmaier, W. & Oberwinkler, F. 1995. Tremelloid haustorial cells with haustorial and potential host ranges of Tremella mesenterica. ‐ Nord. J. Bot. 15: 207–213. Copenhagen. ISSN 0107–055X.In vitro and in vivo haustorial cells of Tremella mesenterica, consisting of a subglobose basal part with one or more thread‐like haustorial filaments, were examined using light and electron microscopy. The haustorial cells developed from clamp connections of hyphal septa or intercalarily. Mostly such haustorial cells were monokaryotic, but in a few cases also dikaryotic haustorial cells were observed. In vitro, the host range of Tremella mesenterica was tested with the corticiaceous homobasidiomycetes Peniophora erikssonii, P. quercina and Phanerochaete eremea. The in vitro interaction of Tremella mesenterica with all these fungi was principally the same as in vivo with Peniophora laeta. A single micropore connected the cytoplasm of the haustorial filament with that of the respective host cell. The pore domain at the host side was delimited by curved ER cisternae only in Peniophora quercina, but not in Peniophora erikssonii and Phanerochaete cremea.
