A powdery mildew fungus on leaves of Dalbergia cultrata var. cultrata (Fabaceae) collected at the Queen Sirikit Botanical Garden in northern Thailand is proven to be a new species of the genus Brasiliomyces and is described as B. chiangmaiensis sp. nov. with light and SEM micrographs. Differences in known Brasiliomyces species are discussed, and a key to species of this genus is provided. 相似文献

A new shore-fly species, Notiphila thaica sp. n. from Thailand, is described. The species is characterized by the following features: antennae yellow, eye-to-gena
index equal to 7: 1, all tibiae and tarsi yellow, and setae on abdominal segments III and IV long and pointing posteriorly.
The species is similar to Notiphila puncta de Meijere in the presence of numerous brown stripes on the thorax, but differs in the absence of velvety-black spots on
the frons, the presence of two strong facial setae, and in the one-color wings. The new species is also very similar to N. phaea Hendel in the structure of the genitalia, but differs in the striped coloration, larger body, and apically widened surstyli.
A key to the Oriental species of Notiphila is given. 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

Summary A new species of Macroptilium sect. Microcochle (Benth.) J. A. Lackey is herein described from the states of Piauí and Bahia, Brazil. Macroptilium cochleatum is characterized by few-flowered inflorescences, calyx teeth longer than the tube, a tightly four-coiled keel, and linear,
patent fruits. The discovery of this unique Macroptilium species, with its distally coiled keel, expands the diagnostic features of the genus. A key to the Brazilian species of sect.
Microcochle is provided. 相似文献

In several surveys in the tropical forests in Thailand, specimens that looked morphologically similar to Metarhizium martiale and Cordyceps variegata, as well as other Metarhizium species were collected and cultured in vitro. A combined phylogeny of several genes including the small (18S) and large (28S) subunits of the ribosomal DNA, elongation factor 1-α (TEF), RNA polymerase II subunits 1 and 2 (RPB1, RPB2) genes has shown these to be new taxa in the Clavicipitaceae. Nigelia is described as a new genus closely related to Metarhizium, to the scale insect pathogens Aschersonia (Hypocrella), Samuelsia and Moelleriella, and to plant pathogens in Claviceps and Balansia, and other relatives. Nigelia comprises M. martiale and a new species Nigelia aurantiaca, which has been found infecting lepidopteran larvae and which produces pseudoimmersed, obliquely arranged, obpyriform perithecia with curved or bent ostioles and with whole (non-separating) cylindric ascospores. Metarhizium chaiyaphumense, M. kalasinense, M. prachinense, M. samlanense, and M. takense are described as new species of Metarhizium. Metarhizium martiale is transferred to Nigelia, and Paecilomyces reniformis is transferred to Metarhizium. 相似文献

Summary A taxonomic revision of the palm genus Podococcus (Arecaceae) is presented. Two species are recognised: P. barteri, a species relatively widespread in a coastal band from Nigeria to the D. R. Congo and P. acaulis, a species previously considered conspecific to P. barteri, almost exclusively confined to Gabon. The taxonomic history, morphology, distribution and conservation status of the genus
and each species are discussed 相似文献

A new species of the genus Camellia L. (Theaceae, Theoideae) is described and illustrated under the name C. cattienensis. This species occurs in the rainforest vegetation of Lam Dong Province, Vietnam. A discussion of the morphological characters
distinguishing this new species from related Camellia species is presented. Morphological evidence supports a transitional taxonomic placement in Camellia sect. Archaecamellia Sealy. This placement is justified by C. cattienensis exhibiting some morphological characteristics also found in sects Stereocarpus (Pierre) Sealy and Piquetia (Pierre) Sealy. 相似文献

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
