A New Species

We present a study on the genus Pholiota sect. Adiposae stirps Subflammans from the Republic of Argentina. Pholiota oblita is proposed as a new species. It is characterized by its narrow lamellae, elongated cheilocystidia and broad spores. Singer originally described this species as P. digilioi, but this name was never validly published. Pholiota oblita is close to P. flammans, from the Northern Hemisphere, and P. subflammans, from the South American Andino-Patagonic forest, but differs by the diagnostic characters previously mentioned. The species was found in the southern end of the Yungas Forest, a cloud forest located on the eastern slopes of the sub-Andean mountains. Numerous collections of P. oblita were found in the Yungas forest but not in other areas. We believe that it could be an endemic species. Furthermore, we found that there are no herbarium specimens for the type of Pholiota subflammans (Speg.) Sacc. With the absence of original material, and to preserve current usage of the name, a neotype is designated hereby. The neotype chosen for P. subflammans is a specimen determined, described, and collected by Singer in the same area where the type specimen was found by Spegazzini.

A New Species

Abstract—Antiphytum charruasorum, a new endemic species from western Uruguay, is described. This is the only South American species in the genus with white corolla and an infra-medial cicatrix on the ventral face of the eremocarp, both features shared with the North American species of Antiphytum, in sharp contrast with the blue corolla and the basal cicatrix at the end of a stipe-like prolongation that characterizes all South American species in the genus. Antiphytum charruasorum increases the diversity of the genus in South America, as well as the endemism and distribution range into Uruguay. Moreover, this new species adds novel features in Antiphytum such as the irregularly dichasial inflorescences, the hirsute faucal appendages, the eremocarps with a tissue plug from the gynobase, and the habitat where the species has been reported.

A New Species

Zamia acuminata has remained an obscure, poorly understood species for over a century due to possibly misinterpreted or erroneous locality data on the unicate sterile type specimen, a very brief protologue description, the misidentification of the plants from El Valle de Antón in Panama as Z. acuminata, and the erroneous determinations of plants of Z. acuminata from Costa Rica as Z. fairchildiana. Recently collected material from San José Province in Costa Rica is here determined to be identical to the single sterile leaf material of the holotype of Zamia acuminata. We consider Z. acuminata to be a Costa Rican endemic species restricted to the western Talamanca mountain range in San José Province, and that the Zamia from El Valle de Antón in Panama, which has previously been referred to as Zamia acuminata, to be a new species, here described as Zamia nana.

A New Species

An updated checklist and key to the Peruvian species of Brunellia (Brunelliaceae) is presented based on georeferenced herbarium specimens from Peruvian herbaria, own field collections and online sources. Thirteen Brunellia species are documented as native to Peru, including nine endemic species. Compared to previous studies the average number of Brunellia spp. per Andean department doubles from two to more than four species. Our data indicate a center of species richness and endemism in northern Peru, namely the Amotape-Huancabamba Zone (AHZ). Furthermore, distribution maps for all species are presented. Brunellia ovalifolia is reported as a new record for Peru. Another species, B. lobinii Böhnert & Weigend sp. nov., from Departamento de Lambayeque, Provincia de Ferreñafe, near the town of Kañaris, is here described as new to science. Additionally, some taxonomic uncertainties are discussed.

AbstractRevision of lichen herbarium specimens at DUKE revealed a species of thelotremoid Graphidaceae new to science. Clandestinotrema carbonera sp. nov. is characterized by an olive-green thallus, dense cortex, the absence of a columella, ascospores 15–24 × 5.5–8.0 μm with 3–5 transverse septa (occasionally submuriform), and the presence of hypostictic acid as a major substance. At present the species is known only from the type locality, an area of montane cloud forest near Mérida, Venezuela. Interestingly, this species appears to have been discussed in the literature once before, as an unnamed ‘Thelotrema sp.’ which in the 1970s provided the first instance of hypostictic acid isolated from a lichen. The previous report of C. leucomelaenum from the same locality is shown to actually represent C. pauperius.

A New Species

A new species of Passiflora belonging to the subg. Tryphostemmatoides from Colombia in the Andean region is described and illustrated from living material, as well as from herbarium specimens. Passiflora nebulosae Restrepo & Ocampo is similar to P. discophora and P. pacifica, but can be recognized mainly by its petiole length (up to 8 mm), leaf margin glands (6‒10), coriaceous leaves, peduncle bifurcate, operculum margin crenate, and limen margin lacerate. The new species is a narrow endemic discovered in cloud forest margins between 1750‒2352 m. It is regarded as critically endangered (CR) because of its restricted occurrence with a small population size.

A New Species

The southeastern Brazilian phytophysiognomy of “campos de altitude” is threatened by the global temperature increase, and because of it, many of its endemic species, such as those of the Asteraceae family, may disappear over the next years. This new species, which occurs in this type of environment, belongs to the genus Heterocondylus (Eupatorieae: Asteraceae), which comprises seven species, mainly with South American distribution. This genus is morphologically variable but all its species share the diagnostic characters, such as: enlarged basal style with variable indumentum, and cypselae with an asymmetrical carpopodium composed of cells with thickened walls. Heterocondylus penninervius is described as a new species from the “campos de altitude” in Serra do Brigadeiro, Araponga municipality, Minas Gerais state, Brazil. The species is recognized by its sessile leaves concentrated in the lower part of the stem, with narrow-elliptical to narrow-lanceolate blade and penninerved leaves, as well as broad capitula with white and pinkish phyllaries. This study provides the description, illustration, taxonomic affinities, flowering and fruiting period and geographic distribution of the species.

A new species, Goniolimon africanum is described and illustrated from Algeria and Tunisia (North Africa). This study, based on investigations of herbarium specimens and data from literature, highlights the fact that this species was collected for the first time by Ernest Cosson and provisionally named ‘Goniolimon luteolus’ nom. nud., while it was later attributed to G. tataricum. A detailed morphological study, carried out on some related European species of Goniolimon, has emphasized that African populations are taxonomically well differentiated from European ones. Its distribution, ecology and relationships are also examined. A table comparing the new species with the closest allied European species of Goniolimon is provided.

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

Representatives of some poorly known spider species collected in the rainforest litter of the Orchid Island (Taiwan) are illustrated and discussed here. A new species, Brignoliella tao sp. nov. (Fam. Tetrablemmidae), endemic to Orchid Island, is described based on both sexes. The previously unknown female of Theridiosoma triumphale Zhao & Li, 2012 (Fam. Theridiosomatidae), is described for the first time. Zoma taiwanica (Zhang, Zhu & Tso 2006) comb. nov., from the same family, is illustrated and its transfer from the genus Theridiosoma O. Pickard-Cambridge, 1879 to Zoma Saaristo, 1996 is proposed on the basis of morphological characters. Habitus and genitalia of the endemic species Gongylidioides angustus Tu & Li, 2006 (Fam. Linyphiidae) are also illustrated.
