T1  - Friedmannia: a new genus from the Seychelles and the beginning of a generic realignment of Curculigo (Hypoxidaceae)
JF  - Phytotaxa : a rapid international journal for accelerating the publication of botanical taxonomy
N2  - Recent molecular phylogenetic reconstruction of the monocot Hypoxidaceae implies that the genus Curculigo is non-monophyletic. Curculigo seychellensis occurs on the Seychelles islands and is part of an isolated though geographically well-defined clade. However, Curculigo seychellensis differs in a wide range of character-states from other species of Curculigo and from the genus Hypoxidia, representing the sister clade of C. seychellensis. Therefore, we here propose a new-though monotypic-genus, endemic to the Seychelles: Friedmannia. A detailed reasoning combined with a whole set of new data is presented. A neotype for the genus and the species is designated here.

T1  - Lactarius megalopterus, a new angiocarpous species from a tropical rainforest in Central Africa, shows adaptations to endozoochorous spore dispersal
JF  - Mycological progress : international journal of the German Mycological Society
N2  - A new sequestrate Lactarius species was found in a humid evergreen tropical rainforest dominated by Fabaceae of the subfamily Caesalpinioideae in Cameroon, Central Africa. It is described here as new to science and is named Lactarius megalopterus, referring to its spore ornamentation of extraordinarily high wings. Anatomical characters and molecular systematic analyses confirm its relationship to Lactarius subgenus Plinthogali. Phylogenetic analyses based on two nuclear DNA regions revealed its close relationship to Lactarius angiocarpus, which is also an angiocarpous species from Zambia in Africa. Molecular studies have shown that tuber-like, sequestrate sporocarps evolved independently in several lineages of Basidiomycota. The findings of sequestrate fungi in tropical rainforests raise questions regarding the evolutionary benefit of enclosing the spore-producing hymenium. The enclosure of spore-producing tissue has often been associated with the protection of the delicate hymenium against desiccation in arid habitats or against frost in cold habitats. However, these cannot be the selective factors in warm and humid areas like the tropics. This controversy is exemplarily studied and discussed in the family of Russulaceae, especially in the genus Lactarius. Characters shown by the angiocarpous sporocarp of the new Lactarius, such as thick-walled statismospores, an aromatic smell and mild taste, can be interpreted as adaptations to endozoochorous spore dispersal by mammals. Therefore, here we prefer the alternative hypothesis that sequestrate sporocarps are the result of adaptation to endozoochorous spore dispersal.
