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.

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.

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, Gabrita erwini, sp. nov. in the tribe Gabritini is described and illustrated from Ecuador, representing the first record of the genus and tribe in northwestern South America which extends its distribution across the Neotropical region from eastern localities in the countries of Brazil, French Guiana and Guyana. Three new species of Sandersellus in the tribe Sandersellini are described and illustrated: S. bigladius, sp. nov. from Bolivia, S. digitatus, sp. nov. from Brazil and S. bilanceus, sp. nov. from Peru. Brazil is a new record for the genus and tribe and extends the distribution eastward from its formerly known western range in Peru, Bolivia and Panama. Taxonomy is reviewed, a revised key to known males and distribution of the known species of Gabrita and Sandersellus are provided.
