Abstract

Poria eichelbaumii, a long-forgotten name, is transferred to Haploporus based on the study of the type specimen, comparison with new collections, and both morphological and phylogenetical evidences. The species is redescribed and illustrated. Haploporus grandisporus also is described as new, on the basis of concordant morphological and phylogenetic species concepts. These two species form two very closely related clades within the Haploporus lineage in [28S-ITS]-based phylogenetic inferences. Haploporus eichelbaumii and H. grandisporus are distinguished by the size of their basidiospores (11.5?14.5 ? 5.0?6.0 ?m, average  12.7 ? 5.8 ?m, vs 14?17.5 ? 6.0?7.3 ?m, average 15.4 ? 6.6 ?m), at a lesser degree by the size of their pores (2.5?3.5 / mm, vs 1.5?2.5 / mm), and likely divergent autecologies. Although both species occur in montane ecosystems of the eastern African rift, they may occupy different habitats. Haploporus eichelbaumii has an ample distribution range, spanning over both branches of the eastern rift, at elevation ~1500?2500 masl, in various vegetation types, mostly on small-sized dead branches or twigs, and dead bamboo culms. It is known so far from Kenya, Tanzania, and Malawi to the East, and western Burundi, western Uganda, and Eastern Congo DRC in the Albertine mountain ranges. Haploporus grandisporus is known, hitherto, only on the Eastern side of Mount Elgon in Kenya, at the timberline, 2900?3200 masl, mostly on dead heather branches (Erica cf. arborea, Ericaceae) in heather thickets. Haploporus nanosporus is currently the third known Haploporus species from tropical Africa. In Africa, it is only known from the western edge of the Guineo-Congolian rain forest in Gabon and Cameroon. The species also is redescribed and illustrated.
