Notes on 113 fungal taxa are compiled in this paper, including 11 new genera, 89 new species, one new subspecies, three new combinations and xx reference specimens. A wide geographic and taxonomic range of fungal taxa are detailed. In the Ascomycota the new genera Angustospora (Testudinaceae), Camporesia (Xylariaceae), Clematidis, Crassiparies (Pleosporales genera incertae sedis), Farasanispora, Longiostiolum (Pleosporales genera incertae sedis), Multilocularia (Parabambusicolaceae), Neophaeocryptopus (Dothideaceae), Parameliola (Pleosporales genera incertae sedis), and Towyspora (Lentitheciaceae) are introduced. Newly introduced species are Angustospora nilensis, Aniptodera

Rhodofomitopsis roseomagna sp. nov. is described as a new species from the Brazilian Atlantic forest based on morphological and molecular analyses. The species is characterized by the brownish to lilac, pileate basidiomata, round pores (5–6 per mm), and cylindrical to subcylindrical basidiospores (4–5 × 2.0–2.5 μm). Phylogenetic analyses based on combined ITS and nLSU rDNA sequences show that the new species belongs to the recently described genus Rhodofomitopsis. We also propose Rhodofomitopsis flabellata and Fomitopsis bondartsevae as new combinations. Notes on some tropical species of Fomitopsidaceae, description and illustration of the new species, and a key to the species of Rhodofomitopsis reported from the Neotropics are provided.

Lacazia loboi is the etiologic agent of Jorge Lobo's disease, a cutaneous and subcutaneous mycosis endemic to Latin America tropical regions and characterized by chronic nodular or keloidal lesions which develop after traumatic events. A new method for the extraction of L. loboi yeast cells from biopsies of lobomycosis skin lesions is presented. The method is based on the proteolytic action of the enzyme dispase which is known for its action against fibronectin and collagen type IV. Fungal identification was based on histological examination of the biological material and molecular analysis based on 18S ribosomal sequences. Observations under optic and fluorescence microscopy proved the efficacy of enzymatic isolation of the lobomycosis etiologic agent, as well as identifying the organism's main parasitic characteristics. Molecular phylogenetic analysis corroborated the histological examination and indicated L. loboi relationship with other members of the Onygenales. Use of dispase proved to be ideal for the isolation of L. loboi from human biopsies, shows promise as an important tool for improving biological studies of this peculiar fungus.

The Bauhinia ungulata, Bauhinia variegata, and Bauhinia purpurea are commonly used in folk medicine. However, few studies have investigated its antimicrobial potential. This study evaluated the in vitro antibacterial effect of crude extracts from leaves of B. ungulata, B. variegata and B. purpurea, in addition to identifying the class of constituents. The evaluation of antimicrobial activity was determined using the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) methods against American Type Collection Culture (ATCC) strains of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Enterobacter aerogenes and Klebsiella pneumoniae. All crude extracts showed similar phytochemical analysis with saponins and tannins and bactericidal activity against all the bacterial strains. The extract of B. variegata stood out with a MIC of 3.6 µg/mL against P. aeruginosa. From this perspective, the extracts of Bauhinia spp. showed promising microbial activity and should be further investigated for the development of antibacterial agents of natural origin.
