“…Although more than 80 species of Daldinia are listed in the Index Fungorum (CABI 2012), this genus has only 25 valid species (Stadler et al 2004) and is characterized by the formation of blackish or colored stromata that are 3-5 cm in diameter and varying shapes, with the tissue below the perithecial layer composed of alternating zones (Guzmán 1977;Ju et al 1997).…”

“…Notes: Daldinia eschscholtzii was first reported in the Philippines (as D. eschscholtzii) and considered a pantropical species (Ju et al 1997). Daldinia eschscholtzii presents similarities with D. concentrica, but differs by having a straight vs. sigmoid germ slit, smaller ascospores (10.5-12 × 5-6 µm vs. 13-17 x 6-7.5 µm), and a stromatal surface with unpapillate ostioles vs. slightly papillate, and KOH-extractable pigments not seen vs. KOH-extractable pigments lively to dark purple (Ju et al 1997;Stadler et al 2004). Van der Gucht (1993) reported the ascospore perispore of D. eschscholtzii with coil-like ornamentation vs. smooth in D. concentrica, and sporulating gray region in the first and ochraceous in the second.…”

Daldinia eschscholtzii (Ascomycota, Xylariaceae) isolated from the Brazilian Amazon: taxonomic features and mycelial growth conditions

et al. 2013

The Amazon has a high diversity of fungi, including species of the genus Daldinia (Ascomycota, Xylariaceae), which produce secondary metabolites with recognized nematicidal and antimicrobial activity. The ecological role of Daldinia is important, as stromata serve as refuges to many insects and arthropodes, and the fungi contribute to the degradation of vegetable organic matter. The aim of this study was to analyze the taxonomic features and mycelial growth conditions in vitro of a Daldinia specimen collected in the Brazilian Amazon. Morphological and molecular studies of the fungus identified it as D. eschscholtzii. To evaluate mycelial growth, we cultivated the fungus at 20, 25, 30, 35, and 40 ºC in malt extract-peptone agar (MEPA), malt extract-peptone (MEP), potato dextrose (PD), and minimum medium (MM). The best mycelial growth occurred at 35 ºC, although the greatest amount of biomass was obtained at 25 ºC and 30 ºC. PD proved to be the best medium for biomass production.

Daldinia eschscholzii (Ascomycota, Xylariaceae) isolado na Amazônia brasileira: características taxonômicas e condições de crescimento micelial RESUMOA Amazônia apresenta alta diversidade de fungos, incluindo Daldinia (Ascomycota, Xylariaceae), cujas espécies produzem metabólitos secundários com reconhecida atividade antimicrobiana e nematicida. O papel ecológico é importante, visto que estromas servem de abrigo para muitos insetos e artrópodes, além de contribuir na degradação da matéria orgânica vegetal. O objetivo desse estudo foi analizar as características taxonômicas e as condições do crescimento micelial in vitro de um espécime de Daldinia coletado na Amazônia brasileira. Estudos morfológicos e moleculares do fungo o indetificaram como D. eschscholtzii. Para avaliação do crescimento micelial o fungo foi cultivado nas temperaturas de 20, 25, 30, 35 e 40 ºC e nos meios de cultura extrato de malte-peptona ágar (EMPA), extrato de malte-peptona (EMP), batata dextrose (BD) e meio mínimo (MM). O melhor crescimento micelial ocorreu a 35 ºC, entretanto, a maior quantidade de biomassa foi obtida a 25 e 30 ºC. O meio BD provou ser o melhor meio para produção de biomassa.

The recent discovery of natural truffle grounds of the prized Tuber magnatum Pico in Sicily (southern Italy) allows to up-to-date the ecology and distribution of this choice edible mushroom in Italy and opens new economic opportunities in rural areas traditionally suffering from the economic point of view. The two new localities reported expand the southern range border of the species in Italy and Europe.
