  • Lactarius megalopterus, a new angiocarpous species from a tropical rainforest in Central Africa, shows adaptations to endozoochorous spore dispersal
    Item type: Journal Article

    Mycological Progress
    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.

  • Venturia orni sp nov., a species distinct from Venturia fraxini, living in the leaves of Fraxinus ornus
    Item type: Journal Article

    Mycological Progress
    Venturia fraxini Aderh. s.l. is an endophytic fungus in the leaves of different ash species like Fraxinus excelsior and F. ornus. This study shows that the Venturia species on F. ornus is not conspecific with V. fraxini s.s., but is a closely related species which is described as a new species: Venturia orni sp. nov. The two species distinctly differ morphologically and genetically. In contrast to V. fraxini, V. orni constantly lacks setae lining the ostiolum of the pseudothecia. In addition, the two species differ significantly and constantly in the sequences of the internal transcribed spacer (ITS) region and the genes coding for calmodulin, elongation factor EF-1α, and β-tubulin. Using the same molecular markers, another unknown endophytic Venturia species was discovered on F. ornus. However, this species never sporulated and, thus, a description of its morphology was not possible. Venturia fraxini and V. orni are host-specific and infect only F. excelsior and F. ornus, respectively, although the two hosts are sympatric at all examined sites. Venturia orni is abundant and exhibits high genetic and morphological variability, also in F. ornus planted as ornamentals outside its native range. This study indicates that Fraxinus spp. host an undiscovered wealth of fungal diversity.
  • Additions to the southern African rust fungi: four new species and two new host genera from South Africa and Angola
    Item type: Journal Article
    Berndt, Reinhard (2020)
    Mycological Progress
    This paper describes four new species of rust fungi from southern Africa. Three of them, Puccinia dimorphothecae-cuneatae on Dimorphotheca cuneata (Asteraceae), P. feliciicola on Felicia filifolia (Asteraceae), and Uredo myricae on Myrica sp. (Myricaceae), were collected in the South African Cape region, while Uromyces hessii on Zantedeschia angustiloba (Araceae) is from Angola. Rust fungi are reported for the first time on the plant genera Thereianthus (Iridaceae) and Cullumia (Asteraceae), both from South Africa. The specimen on Thereianthus was provisionally determined as Uromyces ecklonii that has been known so far only on Freesia. The rust of Cullumia showed only uredinia that were similar to Puccinia clanwilliamensis, hitherto only known on Berkheya.
