Mating Systems in the Xerulaceae: Xerula
Petersen RH and Methven AS. 1994. Mating Systems in the Xerulaceae: Xerula. Canadian Journal off Botany. 72:1151-1163
ABSTRACT: Mating systems in Xerlila australis, Xerula furfiiracea, Xerula incognita (sp.nov.), Xerula megalospora, Xerula rugosoceps, and the Xerlila radicata complex are described, with notes on culture morphology and biogeographic distribution. All taxa tested were bifactorial (i.e., tetrapolar) and genetically isolated from one another. Multiple collections of X. furjkracea and X. megalospora were found to interbreed in vitro. Two collections of putative European X. radicata were found to be haploid, monokaryotic, nonmeiotic basidiomes genetically isolated from each other and from all other tested taxa, including X. radicata. Neohaploidization experiments with Xerula rufobrunnescens failed. A discussion comparing mating systems in Xerula to those in other genera of the Xerulaceae is included.
