Geastrum species from the Amazon Forest, Brazil

Abstract

Six Geastrum species are reported from the Amazon forest: G. entomophilum, G. fimbriatum, G. javanicum, G. lageniforme, G. lilloi, and G. saccatum. Geastrum javanicum and G. lilloi represent first records from Brazil. Descriptions and illustrations of the species and SEM images of microstructures are given.

<i>Geastrum sanglinense</i>, a new species from the Manghe Rhesus Monkey National Nature Reserve, China

“…The phylogenetic tree (Fig. 1) based on ITS, nrLSU, and atp6 showed that Geastrum is a multilineage genus, which is consistent with previous studies (Lloyd, 1902(Lloyd, , 1907Sunhede, 1989;Douanla et al, 2005;Kirk et al, 2008;Leite et al, 2011;Kasuya et al, 2012b;Jeppson et al, 2013;Zamora et al, 2013Zamora et al, , 2014aZamora et al, , 2014bZamora et al, , 2015Accioly et al, 2019).

“…Differs from G. fimbriatum Fr. by smaller basidiospores, fibrillose peristome and rhizomorphs covered with narrow prismatic crystals (Leite et al, 2011). Also differs from G. yanshanense by the light grayish orange pseudoparenchymatous layer (yellowish brown in G. yanshanense), and the larger basidiospores (2.8-3.3 μm in G. yanshanense) (Zhou et al, 2022).…”
