Abstract
Lichenothrix riddlei is reported from two widely separate localities in New Zealand. It was previously known only from the South Eastern states of U.S.A. Light and electron microscopy show its sterile fungal partner to belong to the ascomycetes. Apparently as a consequence of lichenization, the variation in breadth of the trichomes of theScytonema phycobiont is greater than normal. A thin, probably gelatinous layer, covering the fungal cells and the algal sheath in the interstices between them, can be demonstrated by electron microscopy. In the contact region with the algal cells, the otherwise two layered wall of the haustoria is reduced to one layer only. In the fungal protoplast conspicuous stacks of ER-like membranes can be found.
