A New Species

A new species of Calvatia is described from a semideciduous seasonal forest fragment in the western region of Paraná State, southern Brazil. Calvatia guzmanii is proposed as new based on the combination of dark brown and spiny to velvety exoperidium, prominent subgleba and echinulate-reticulate basidiospores with a short pedicel. A comparison with morphologically similar Calvatia species is giv

A New Species

Piriqueta pampeana, a new species of Turneraceae, is described and illustrated here. The species occurs in the municipalities of Alegrete, Maçambará, Manoel Viana and São Francisco de Assis, in the western region of Rio Grande do Sul state, Brazil. It resembles Piriqueta suborbicularis and Piriqueta taubatensis, but can be distinguished by the presence of a pair of discoid basilaminar nectaries, a pair of petiolar nectaries and small nectaries distributed along the leaf margin, sepals with acute apex and a yellow spot at the base of the petals. Due to the intense environmental degradation of  its habitat, and according to IUCN guidelines, we ranked the species as “Endangered” (EN).

Three species of Panaeolus were collected in the western region of Paraná State, South Brazil. Panaeolus sylvaticus is proposed as a new species, based on macro- and micromorphological features and substrate (rotten wood and litter). Panaeolus antillarum and P. papilionaceus var. parvisporus, two coprophilous and widely distributed species, are also reported. All species are illustrated and discussed in detail, regarding their taxonomy, ecology and distribution. A key to the known species of Panaeolus from Paraná State is presented.

A New Species

Prosopanche cocuccii is described as a new species from Southern Brazil. It resembles P. bonacinae due to the trigonous rhizome and by the general size of the flower organs. Nevertheless, P. cocuccii is distinguished by the main floral morphological characteristics used to differentiate species. In addition, the new species presents some rare characters for the genus, such as a highly branched rhizome and flowers usually grouped in fascicles. We provide a description, illustrations, field photographs, morphological details under the stereomicroscope, and comments on habitat, ecology, distribution, and conservation of the new species, as well as an updated key for the genus Prosopanche. In addition, we identified that P. cocuccii produces a large number of rhizomes and fruits for each single host specimen of tobacco (Nicotiana tabacum), which resulted in a decrease in height and growth of its only known host plant.

A new species of Persicaria, P. humboldtiana, endemic to a narrow area of waterfalls in Corupá, southern Brazil, is described in the present paper. The locus classicus of the new species is well-known for plant endemisms. A complete morphological description, original pictures, a distribution map, and a morphological comparison with the similar Eurasian species P. minor (≡ Polygonum minus) are given. The name Polygonum minus is lecto- and epitypified on, respectively, a Morison’s illustration and a specimen preserved at BM.

Valeriana iganciana, an endemic species from the Serra do Tabuleiro highlands of Santa Catarina state, southern Brazil, is described and illustrated. The new species shares morphological affinities with V. ulei, from which it is distinguished mainly by leaves with entire margin, by the cymose architecture of the inflorescence and by the triquetrous and elliptical fruits with annular to dentate calyx.

A New Species

The Brazilian records on Xenacanthiformes include teeth and cephalic spines from the Parnaíba, Amazonas and Paraná basins. This work describes a new species of Xenacanthidae, collected in an outcrop of Serrinha Member of Rio do Rasto Formation (Wordian to Wuchiapingian), Paraná Basin, municipality of Jacarezinho, State of Paraná. The teeth of the new species are two or three-cuspidated and the aboral surface show a smooth concavity and one rounded basal tubercle. The coronal surface presents one semi-spherical and subcircular coronal button, and also two lateral main cusps and one central (when present) with less than one fifth of the size of the lateral cusps in the labial portion. The lateral cusps are asymmetric or symmetric, rounded in transversal section, lanceolate in longitudinal section, devoid of lateral carinae and lateral serrations, and with few smooth cristae of enameloid. In optical microscope the teeth show a trabecular dentine (osteodentine) base, while the cusps are composed by orthodentine, and the pulp cavities are non-obliterated by trabecular dentine. The fossil assemblage in the same stratigraphical level and in the whole Rio do Rasto Formation indicates another freshwater record for xenacanthid sharks.

External Aperture

A new species of Triceratiaceae is described for estuarine environments of Southern Brazil. The valve of Triceratium moreirae sp. nov. is triangular with elevations bearing ocellus and a rimoportula in their basis. The valvar surface has robust pseudoloculi, circular to polygonal, each one confining a group of areolae arranged in a typical pattern. A central larger areola is surrounded by 5-8 smaller areolae, and they are poroidal with domed cribra. A septum emerges from the valvocopula, having the base reinforced by ribs and the margins folded to the innerside of the valve. The new species is compared to the closely related diatom Triceratium dubium, which has the same pattern of areolar disposition, formation of septum and pseudoloculi. The main diferences in relation to T. moreirae are: rimoportulae intercalated to ocelli and with a characteristic morphology (spinules on the edge of the external aperture), and more elongated elevations with a constriction. Some criteria used for the classification of categories into the Triceratiaceae are also discussed, and we propose that the type of areola (poroidal with cribra) be included in the circumscription of Triceratium.
