Three new species of thelotremoid Graphidaceae are described from tropical Africa. Astrochapsa fusca Lücking differs from A. platycarpella in the brown thallus and larger ascospores with more numerous septa. Ocellularia abbayesiana is similar to O. exuta in morphology and chemistry but has smaller, hyaline ascospores. Ocellularia grantii resembles O. terebrata in the carbonized excipulum and columella, the hyaline, transversely septate ascospores, and the psoromic acid chemistry, but is distinguished by its verrucose-bullate thallus, white-tipped columella, and smaller ascospores. The three species were discovered in historic material collected between 1874 and 1954 and underline the importance of revising herbarium collections for the discovery of novel taxa.

Background and aims – The genus Tricalysia A.Rich. (Rubiaceae), regarded here in the strict sense (i.e., excluding Empogona Hook.f.), includes 77 species in tropical Africa, Madagascar and the Comoros. In the current paper, three new species from Atlantic Central Africa are described and illustrated; their conservation status is also assessed.Material and methods – This paper is based on a study of herbarium collections from BR, BRLU, K, LBV, P, WAG and YA. Normal practices of herbarium taxonomy have been applied. The conservation status assessments follow the IUCN Red List criteria.Results – Tricalysia lophocarpa O.Lachenaud & Sonké is endemic to Gabon and is best recognised by its fruits with 8–10 narrow longitudinal ribs. Tricalysia obovata O.Lachenaud & Sonké is endemic to Equatorial Guinea (Rio Muni) and may be recognised by its obovate leaves with rounded base, glabrous stems, and sessile flowers with included style and half-exserted anthers. Tricalysia wilksii O.Lachenaud & Sonké occurs in Gabon and southwestern Republic of Congo, and may be recognised by its glabrous stems and leaves, the latter with crypt domatia, its linear calyx teeth equalling or exceeding the tube in length, and its shortly pedicellate fruits. The three species are assessed respectively as Near-threatened (T. lophocarpa), Critically Endangered (T. obovata) and Vulnerable (T. wilksii).

Three New Species

Three new species of Graphidaceae are described as new to science from tropical Africa: Graphis aptrootiana Van den Broeck, Lücking & Ertz and Redingeria desseiniana Van den Broeck, Lücking & Ertz from the Democratic Republic of the Congo, and G. vandenboomiana Ertz, Lücking & Van den Broeck from Reunion. A key is presented to all known species of Redingeria. The lichenicolous fungus Etayoa trypethelii is mentioned as new to Central Africa.

Three New Species

Three new species from Angola are described: Vernonia lainzii, Vernonia longibracteata, and Vernonia platyseta (Asteraceae, Vernonieae). Morphological differences with putative related taxa are detailed and discussed. Vernonia lainzii is most similar to V. antunesii O. Hoffm., from which it can be distinguished largely on the basis of leaf pubescence, phyllary morphology, and pappus color and morphology. Vernonia longibracteata is most similar to V. thodei E. Phillips and V. praemorsa Muschl., from which it can be distinguished largely on the basis of degree of branching of the scape, leaf pubescence, petiole length, phyllary size and morphology, and outer pappus length. Vernonia platyseta is most similar to V. anandrioides S. Moore and V. longipedunculata De Wild. It can be distinguished from the former principally on the basis of habit type, leaf pubescence, involucre width, phyllary morphology and texture, and pappus morphology, and from the latter principally on the basis of habit type, involucre width, phyllary morphology, and pappus length.Key words: Asteraceae, Vernonieae, Vernonia, new species, tropical Africa, Angola.

Three New Species

Summary Three new species of Inversodicraea (Podostemaceae), I. senei from the Memv’ele falls of the Ntem River, Cameroon, I. tanzaniensis from the Ruhudji River near Lupembe, Southern Highlands, Tanzania, and I. botswana from the Kasane rapids on the Chobe River, Botswana, are described and illustrated. All three species are known from single sites. All three are assessed as Critically Endangered using the IUCN standard. With 35 species, Inversodicraea is the most species-diverse genus of Podostemaceae in continental Africa, to which it is endemic. Four species of Inversodicraea are now known to be sympatric and point endemics at Memv’ele Falls in Cameroon where a hydro-electric dam is being constructed, threatening them with global extinction. Equally, I. tanzaniensis is threatened by proposed hydro-electric projects in Tanzania. In contrast, I. botswana is threatened by sewage discharge and also by bridge construction.

The knowledge of the clearwing moth genus Lolibaia Gorbunov & Gurko, 2017, recently described from South Sudan and until now known only from a single, damaged specimen, is extended by three new species from different parts of Africa including the as yet unknown female of the genus. L. jurateae sp. nov. is based on a single male from Kakamega Forest, Kenya; L. triangularis sp. nov. is based on six males from different localities in north-western Zambia, and L. polythyris sp. nov. is described from two females from the Eastern Cape and KwaZulu-Natal Provinces, South Africa.

Three New Species

We provide an updated account on the species of the Cruentotrema-Dyplolabia clade in Graphidaceae subfamily Fissurinoideae, describing three new species: Cruentotrema lirelliforme J. Kalb, Polyiam & K. Kalb, differing from Cruentotrema thailandicum in the lirelliform ascomata; Dyplolabia chumphonensis J. Kalb & K. Kalb, differing from Dyplolabia oryzoides by smaller ascospores; and Dyplolabia dalywaiana Rivas Plata, Bawingan & Lücking, differing from other Dyplolabia species in the angular, erumpent asomata with broadly exposed disc and irregular pseudocolumella. In addition, two further species are recognized as new combinations: Cruentotrema puniceum (Müll. Arg.) J. Kalb & K. Kalb (Bas.: Arthothelium puniceum Müll. Arg.; syn.: Thelotrema rhododiscum Homchant. & Coppins) and Dyplolabia ochrocheila (Vain.) Rivas Plata & Lücking (Bas.: Graphis ochrocheila Vain.). Cruentotrema kurandense is reported as new to Thailand. Altogether, 11 species are now recognized in the two genera, six in Cruentotrema and five in Dyplolabia. In view of the disparate morphology of the two genera, the discovery of two of the three new species is highlighted as phenotypically transitional taxa, so-called ‘missing links’, and the phylogeny of this clade is revised.

Cultures and herbarium collections of the previously described species of Ascosphaera were studied. Additional observations are reported on Ascosphaera strains associated with the alfalfa leaf-cutting bee, Megachile rotundata (Fab.). Three new species of Ascosphaera are described, all occurring in brood cells of the alfalfa leaf-cutting bee. Ascosphaera larvis sp.nov., with short, ellipsoidal ascospores, was frequently associated with a chalkbrood-like disease in early-instar larvae. Ascosphaera pollenicola sp.nov., a homothallic species with subcylindric ascospores, most often occurred on pollen provisions in brood cells. Ascosphaera variegata sp.nov., with conspicuously mottled ascomatal walls, was isolated from pollen and also from larvae that had died from undetermined causes. Descriptions and an identification key are provided for the 11 species of Ascosphaera currently recognized.
