species from the Atlantic Forest. – Sydowia 77: 39–52.

Phylloporia is morphologically characterized by resupinate, sessile to stipitate, annual to perennial basidiomata with a duplex context, monomitic to dimitic hyphal system, simple septate generative hyphae, lack of setae and yellowish to brown, subglobose, ellipsoid to cylindrical spores. The genus has worldwide distribution, with species parasites on plants or saprotrophic.
Several new species of Phylloporia have been described in the tropics in the recent years, and the studies indicate morphological complexes within the genus. Thus, the diversity of Phylloporia was investigated during fungal surveys in areas of the Atlantic Forest in Northeastern of Brazil. Morphological and ITS and LSU phylogenetic analyses were performed and four new species are described. Phylloporia albomarginata and P. gracilis are stipitate with semicircular to spathulate pilei, similar to P. spathulata, while P. alagoana and P. darwiniana are sessile species. Descriptions, illustrations and a table with the morphological characteristics of the species described to Brazil and confirmed through molecular analysis are provided, improving the knowledge of Phylloporia in the country and the Neotropics.
