Summary
Calathea dryadica and Calathea reginae are described, circumscribed and illustrated. These new species are probably endemic to the Atlantic Forest of Rio de Janeiro
State in Southeast Brazil and are considered critically endangered because of the restricted geographic area of occurrence,
sometimes enclosed by densely urbanised areas. 相似文献

Elaphoglossum mickeliorum, a new species from the eastern slopes of the Peruvian Andes, is here described and illustrated. It belongs to E. sect. Polytrichia, which is characterized by the presence of subulate scales and absence of hydathodes on the sterile leaves of adult sporophytes. Herbarium specimens of this new species were first collected by Alwyn H. Gentry ca. 40 years ago, but these got readily confused with E. erinaceum and went undescribed since then. The new species differs from members of the E. erinaceum complex by having a nearly continuous band of planar, nonsubulate scales along the laminar margins of sterile leaves. Based on this character, E. mickeliorum resembles species such as E. glaziovii, E. ornatum, and E. scolopendrifolium. It differs from these by the presence of minute glandular hairs on petioles and costae. A distribution map and a figure with line drawings are also provided. For comparative purposes, the line drawing includes E. blepharoglottis, which is here illustrated for the first time. 相似文献

Two new species of Lirula (L. japonica and L. exigua) on Abies mariesii collected in subalpine areas of northern Japan are described as members of Rhytismatales, Discomycetes. Lirula japonica causes needle cast in fir, but L. exigua seems to occur on the needles of physically damaged twigs. Morphological characteristics of both species are discussed. 相似文献

Two new species of Erythroxylum from the Amotape-Huancabamba region are described and illustrated. Erythroxylum dillonii occurs in the arid zones of northern Peru, and Erythroxylum gentryi is known only from the Ecuadorian side of Cordillera del Condor. Their habitats and taxonomic relationships are discussed. 相似文献

A new Dactylella species, Dactylella alba was isolated from the ascospores of Orbilia alba collected in Wenshan County, Yunnan Province, China. Conidiophores were either not branched or occasionally branched, bearing
divergent sterigmata on the tip with single conidium on each. Conidia were elongated ellipsoids, 1–2 septate, mostly 1 septate.
By combining the ITS sequence with morphological characteristics, a new anamorphic species is described and illustrated together
with its teleomorph. 相似文献

Two new species of Goniopteris endemic to the state of Espírito Santo (Brazil) are described and illustrated: Goniopteris bradei and G. salinoi. Morphological comparisons with similar species, as well as two identification keys, are presented. One key includes the Brazilian species most similar to G. bradei, and the other includes those Goniopteris species with glandular hairs, including G. salinoi. 相似文献

Ongoing taxonomic work on Mezilaurus has revealed two new species of the genus in Brazil, which are here described and illustrated. The first one, Mezilaurus glabriantha, from the state of Espírito Santo, represents the third endemic species known from the Brazilian Atlantic Forest, and Mezilaurus microphylla occurs in seasonally dry forests from the central Brazilian state of Tocantins. A key to distinguish the extra-Amazonian species of Mezilaurus from Brazil is provided. 相似文献

Two new species, Pseudopyricularia hyrcaniana and P. iraniana, are described, illustrated, and discussed in this paper. Phylogenetic analyses of the large subunit of the ribosomal RNA gene cluster and their internal transcribed spacer regions, and protein encoding gene introns and exons, including the largest subunit of the RNA polymerase II and calmodulin, confirmed their placement in Pseudopyricularia. Pseudopyricularia hyrcaniana was isolated as a pathogen from leaves of Cyperus alternifolius, while P. iraniana was from Juncus sp. Conidia of P. hyrcaniana are obclavate and 1-septate; those of P. iraniana are fusiform or cylindrical and 2-septate. Analyses of multigene sequences confirm the distinction between P. hyrcaniana and P. iraniana, and reveal their relationship with their allies in Pyriculariaceae. 相似文献
