The data presented in this article are the results of field collections and the analysis of fungal specimens deposited in the URM Herbarium. The field trips were carried out in four Atlantic Forest remnants in the state of Pernambuco, between June 2008 and May 2009. The revision of specimens housed in the URM was restricted to the Brazilian exsiccatae. Geastrum specimens were examined macro- and microscopically following the traditional methodology used in the group. Geastrum javanicum and G. lloydianum are new records from the Northeastern Region of Brazil. Eight species are new records from the following states: Pará (G. fimbriatum), Ceará (G. lloydianum), Paraíba (G. fimbriatum, G. javanicum, G. schweinitzii and G. entomophilum), Pernambuco (G. lageniforme and G. triplex) and Rio de Janeiro (G. javanicum). In this article we present full descriptions for ten species of Geastrum with pictures and an identification key.

“…Lentinus crinitus (L.) Fr. (Basidiomycota) is a wild fungus with pantropical and neotropical distribution (Silva and Gibertoni, 2006), mainly in Brazil (Groposo and Loguercio-Leite, 2005;Gomes-Silva and Gibertoni, 2009). It is a saprophyte fungus that grows in trunks of decomposing trees (Abraham and Abate, 1995) and produce enzymes like laccase (Valle et al 2014), cellulase, xylanase (Cambri et al 2016), phytase (Pereira, 2015) and proteases (Kirsch et al 2013;Machado et al 2016) with potential applications in industrial and biotechnological processes.…”

Fungus ability to respond to environmental changes allows their adaptation to a wide variety of conditions such as pH, temperature, light, nutrient availability, chemicals, and competition among species. Temperature and pH can affect fungal growth as well as their metabolism. Knowing these factors on fungus species is relevant for the development of biotechnological applications and process optimization to produce biomass and enzymes. This study aimed to evaluate Lentinus crinitus mycelial growth and laccase production at different initial pH and temperatures of the cultivation medium. L. crinitus U15-9 reduced laccase production with pH increase with maximum production at pH 6 (39 U/mL) whereas L. crinitus U9-1 increased laccase production with pH increase with maximum activity at pH 7 (25.8 U/mL). Neither of the strains had mycelial growth significantly affected by initial pH in the culture medium. The greatest laccase production occurred at 28°C for U15-9 (50 U/mL) and U9-1 (41.5 U/mL). An increase in U9-1 mycelial biomass occurred when the temperature went up from 25 to 28°C whereas for U15-9 it was from 28 to 37°C; at 37°C, U15-9 produced 225% more mycelial biomass than at 28°C, and 108% more mycelial biomass than U9-1 at 37°C. The variation of responses to environmental stimuli between the strains makes evident that intra-specific variations are common in basidiomycetes. Our findings highlighted the best conditions of pH and temperature to produce L. crinitus laccase and make evident how different strains respond distinctly to cultivation conditions.

Coltricia globispora sp. nov. is described as new based on specimens collected in the Parque Natural Municipal de Porto Velho, in the state of Rondônia, Brazilian Amazonia. It is characterized by small pores (7-8 per mm), monomitic hyphal system, and globose, smooth and guttulate basidiospores (5.5-6.6 (−7) μm). Phellinus griseoporus has been found for the first time in Brazil, and Cyclomyces iodinus, P. merrillii, P. membranaceus and P. umbrinellus in the Brazilian Amazonia. Coltricia cinnamomea, P. calcitratus and Phylloporia chrysites are new occurrences to the state Rondônia, while C. hamata and Phylloporia spathulata to the state of Pará. The knowledge about Hymenochaetaceae in the Brazilian Amazonia is briefly discussed, and a key to the neotropical species of Coltricia is provided.
