Begonia species is one of the ornamental plants that have unique leaf appearance and metabolites. Research objectives are to isolate, identify and preserve microfungi on Begonia spp. Purposive sampling methods at the Begonia greenhouse of Bogor Botanical Garden, Bogor, were used to collect the microfungi in August 2022. Seven species of Begonia were checked for microfungi. Namely, Begonia blirik, B. crested, B. fiandani, B. natunaensis, and Begonia spp. Morphological character showed that microfungi found are Botrytis spp., Colletotrichum spp. and sterilia miselia. The edaphic environment data were also monitored. This is the first study of microfungi diversity on Begonia spp. in Indonesia. The microfungi will be illustrated and described in this paper.

This study aims to review the occurrence of microplastics in some commercial aquatic organisms. Microplastics are small plastic particles with a diameter of less than 5 mm. Effluent, stormwater, agricultural, and surface runoff introduce microplastic to freshwater basins. Hydrodynamics and hydrology encompass microplastics. River flow speed can cause turbulence and riverbed instability, increasing microplastic concentrations. Fish, shellfish, and crustaceans ingest microplastics in proportion to their quantity in freshwater and marine environments. Human activities cause variations in the form, color, and size of microplastics in the biota. Animals absorb microplastics through trophic transfer. Increased microplastic residence time before ingestion promotes trophic transmission. Lower food concentration and aggregation enhance microplastic retention in zooplankton guts, increasing transmission to higher-trophic-level species. Most studies show that microplastics in biota are discove...

The objective of this study was to know the stability of bioactive production of Monascus fermented rice (MFR) by Monascus purpureus JMBA after six years storages by using HPLC and Spectrophotometer. The results showed instability in the use of M. purpureus culture based on the bioactive yield analysed. Despite there were still bioactive which was detected by HPLC in FMR after six years storages, however, this results also indicated a tendency towards lowering red or yellow pigment and lovastatin yields of the fermented products over the tenth descendants. Further study is needed to clarify instability in producing bioactive by M. purpureus JMBa, MFR product in particular.

APS press 2012; 8.5×11″ hardcover; 1480 pages; 650 line drawings; 2800 micrographs ISBN 978-0-89054-398-6 This nicely laid out book which is referred to as "Holy Book of Smut Fungi" is an essential tool in helping the scientific community to identify smut fungi everywhere. This won-derful guide contains keys to the genera and species and a host plant–smut fungus list and compiles more than 3,500 micrographs and line drawings into a single sourcebook. Fifty years of collecting and describing smut fungi spe-cies by Dr. Kálmán Vánky, the worldwide authority on the subject, has resulted to a 1,500-page treatise. The book provides complete and detailed presentations of species in 93 genera through descriptions and illustrations and updates our knowledge of valid scientific names and synonyms and provides taxonomic references and the host plant range of each species. The excellent illustrations and detailed descriptions complement other guides to aid the lay person in getting th...

Guignardia musae is the reported causal agent of freckle disease of banana. The epithet has, however, been introduced on three separate occasions and only one name is valid. We therefore investigated this problem. We examined the types of G. musae Racib., G. musae F. Stevens and G. musae Syd. & P. Syd. and also made fresh collections from banana in northern Thailand. Guignardia musae Racib. is the earliest name and takes precedence over the other two names which are hononyms. G. musae F. Stevens is a different species and therefore a new name G. stevensii Wulandari & K.D. Hyde is introduced to accommodate it. The name G. sydowiana Trotter has previously been introduced to accommodate G. musae Syd. & P Syd.; type material is, however, depauperate. Guignardia musicola Wulandari, L. Cai & K.D. Hyde sp. nov. is introduced as a new species from Thailand. The three species from banana are compared and their differences described.

Phyllosticta as an important plant pathogenic genus associated with plants as endophytes, pathogens or saprobes. Phyllosticta sterculiae occurs on Sterculia foetida (Sterculiaceae) in the Philippines, where it causes a leaf blight. The holotype of P. sterculiae is redescribed and compared with a Phyllosticta species collected on Sterculia monosperma in Thailand. P. sterculiae has oblong to obovoid ascospores whereas the fungus from Thailand has ellipsoidal ascospores that are swollen in the middle and possess polar appendages. The comparison between other Phyllosticta species on Sterculiaceae revealed Phyllosticta species from Thailand collection is different in ascospores dimention. Furthermore, the anamorph in culture compare to the Thailand collections with Phyllosticta melochiae from Indonesia on host subtrate posseses similar character. The BLAST result showed that the Thailand species is belonging Phyllosticta capitalensis. The need of epitypification for all the Phyllosticta ...

Conidial states of Guignardia are in the genus Phyllosticta. In accordance to nomenclatural decisions of IBC Melbourne 2011, this paper validates species that were in Guignardia but are now accepted in Phyllosticta. The conclusions are arrived based on molecular analyses and morphological examination of holotypes of those species previously described in the genus Guignardia. Thirty-four species of Phyllosticta, viz. P. ampelicida (Engelm.) Aa, P. aristolochiicola R.G. Shivas, Y.P. Tan & Grice, P. bifrenariae O.L. Pereira, Glienke & Crous, P. braziliniae O.L.

Guignardia plays an important role as plant diseases and endophytes. Its can switch from endophytes become pathogen in the favorable condition. The objectives of the research are to screening the presence of Guignardia-Phyllosticta species and to know their morphological and cultural characteristics. From thirty different plants has result with only thirtheen cultures of Guignardia-Phyllosticta from Aglaonema sp., Allocasia sp., Anthurium sp., Centella asiatica, Citrus maxima, Dieffenbachia sp., Nothopanax scutellarium, Pinus merkusii, Sansevieria sp., Allocasia sp. 2, Callophyllum sp., Bauhinia sp. and Tinospora craspa. Malt Extract Agar (MEA) and Rose Bengal (RB) were used for screen the Guignardia/Phyllosticta spp. The right colonies were transferred to (MEA, PDA, OA and CMA) media. The growth rates were made in MEA with three replications in 24 0 C. WA and pine needle were used for inducing the teleomorph stage (Guignardia spp). The propagule of Guignardia/Phyllosticta recorded ...
