A New Species

Based on fieldwork and an extensive analysis of herbarium and type collections, a new species which grows in sedimentary soil in the Brazilian semiarid region, Erythroxylum pyan (Erythroxylaceae), is described here. The new species occurs in areas of hyperxerophilic caatinga in the states of Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, and Bahia. Erythroxylym pyan resemble E. nummularium, but can be distinguished by having slender branches, foliar stipules non-striated longitudinally, 2-setulose at apex, leaf blades membranous to slightly chartaceous, emarginate to retuse at apex, inflorescences with 1 flower per node, long, slender and erect pedicels, and calyx lobes cuspidate at apex. Additionally, a distribution map and data about its phenology, conservation status, and uses are provide.

Erythroxylum angelicae, a new species of Erythroxylum sect. Archerythroxylum, is described and illustrated. This species occurs in “Carrasco” vegetation of the state of Ceará, northeastern Brazil. It is recognized by the persistent cataphylls, non-striated, long-triangular, and palleaceous; stipules non-striated, 3-setulose; flowers subsessile, calyx lobes triangular, and styles free. Affinity relationships with other species of Erythroxylum are also presented and discussed.

Studies carried out in tropical rain forest enclaves in semiarid region of Brazil revealed a new species of Calvatia. The basidiomata were collected during the rainy season of 2009 and 2012 in two states of Northeast Brazil. Macroscopic and microscopic analyses were based on dried basidiomata with the aid of light microscope and scanning electron microscope. Calvatia nodulata is recognized by its pyriform to turbinate basidiomata, exoperidium granulose to pilose and not persistent, subgleba becoming hollow at maturity, nodulose capillitium, and punctate basidiospores (3–5 μm). Detailed description, taxonomic comments, and illustrations with photographs and drawings are provided.

A New Species

Coprinellus phaeoxanthus A.R.Gomes & Wartchow is described as a new species and is characterised by cordiform basidiospores similar to those of the recently described Coprinellus arenicola. However, it differs in the presence of voluminous pleurocystidia in the velar elements, which are shorter than in Coprinellus arenicola, and in the lack of clamp connections. In addition, exsiccatae of a Brazilian collection identified as ‘Coprinus xerophilus’ are analysed, and because of the star-shaped velar patch on the pileus and the non-volvate stipe base, it is considered to be the same as Coprinus calyptratus, representing a new record from South America.

A New Species

A new species of the genus Mutinus has been found in the semiarid region of Northeastern Brazil. Mutinus albotruncatus is described macro- and microscopically, and is characterized by the white pseudostipe and truncated apex. Molecular and ecological data are also provided. Phylogenetic analyses, based on LSU (large subunit of nuclear ribosomal DNA) and atp6 (subunit 6 of ATP synthase) sequences, support the inclusion of this new species in the genus Mutinus. A provisional key to the species of Mutinus known in the world is proposed.

A New Species

Standleya glomerulata, a new species and a first record for the semiarid region of Bahia, Brazil, is described and illustrated. It differs from all other known species of the genus by its prostrate decumbent and reptant habit, glomerulate sessile inflorescences, and a calyx with two unequal lobes. S. prostrata has a similar habit, but can be distinguished by the pedunculate inflorescences and a calyx with four equal lobes. The new species is known from only a few localities in two protected areas and must therefore be considered threatened.

A New Species

During a soil survey for Mucorales in a semiarid region of the state of Pernambuco, Brazil, a specimen of Absidia (URM 8213) was isolated. Both morphological and phylogenetic analyses (ITS and LSU rDNA regions) of this specimen showed that it is a new species. The new species differs from other species in the genus in its ability to concomitantly produce isolated or whorled sporangiophores of up to 8 with fig-shaped and hemispherical columellae, as well as globose, subglobose, and cylindrical sporangiospores. Thus, in this study, we propose a new species of Absidia.
