Yinmingella mitriformis gen. et sp.nov. (Hyphomycetes), occurring on wood submerged in Tung Chung River on Lantau Island, Hong Kong, is described and illustrated. It is unique in producing short, true chains of holoblastic, aseptate, smooth, black, mitriform conidia from dark brown, flask-shaped conidiogenous cells on hemispherical, black stromata. Yinmingella is compared with Hemibeltrania, Hemicorynespora, Mammaria, Janetia, Sporidesmium, and Stanjehughesia.Key words: cryo-SEM, dematiaceous Hyphomycetes, freshwater fungi, mitosporic fungi, systematics.

During a survey on diversity of freshwater fungi along a north-south latitudinal gradient in Asia, three fresh specimens of Minimelanolocus were collected from submerged wood in streams in northwestern Yunnan Province, China. Based on their distinct morphological features and phylogenetic analyses of combined ITS, LSU and SSU sequence data, Minimelanolocus nujiangensis and M. clavatus are described as new species and M. submersus was recollected from Yunnan, China. Illustrations and descriptions with notes of the three species are provided. This study increases the known diversity of Minimelanolocus and enriches freshwater fungal resources.

Greater Mekong Subregion

During our surveys of freshwater fungi on submerged wood in the Greater Mekong Subregion, a rhexodenticula-like taxon was collected, described and illustrated. The new collection is identified based on analyses of combined LSU, SSU, ITS and TEF sequence data, and morphological comparison with other Rhexodenticula species. According to the morphology and molecular analysis, our collection is not known before and hence, we introduce here as Rhexodenticula aquatica sp. nov. This species is characterized by macronematous, subcylindrical, unbranched conidiophores, polyblastic, terminal conidiogenous cells and fusiform, 3-septate, verruculose conidia, and schizolytic conidial secession. Rhexodenticula is referred to Sordariomycetidae genera incertae sedis due to its unstable phylogenetic placement in Sordariomycetidae.

Construction-related loss of habitat, degradation of existing habitat, noise pollution, and vessel activity are growing issues for Indo-Pacific humpback dolphins (Sousa chinensis) that occur in the shallow, near-shore, highly industrialized waters off Lantau Island, Hong Kong. We studied the occurrence of dolphins in discrete locations, fine-scale movement patterns, and dolphin behavioral activity states. Potential explanatory variables varied and included year, season, time of day, dolphin group size and behavioral activity state, proximity to construction activity, and vessel type and number. Land-based observations and theodolite tracking of dolphins and vessels were conducted from seven locations to the north of Lantau Island, Hong Kong, and marine construction activities near survey sites were identified. A total of 636 groups of dolphins were recorded, totaling 150.91 h of tracking, from 405 days of observation effort. Hurdle models were used to analyze dolphin occurrence, multivariate generalized additive models were used to analyze fine-scale movement patterns, and log-likelihood ratio and binomial z score post hoc tests were used to analyze behavioral activity states. Dolphin occurrence was lower in historically important areas near long-term, low-intensity construction activity, and dolphin swimming speed was higher in response to vessel presence. Overall, foraging and traveling were the most frequently observed behavioral activity states and resting behavior was observed off only one location that was not in proximity to construction activities. Temporal overlap in adjacent marine construction areas may displace animals for extended periods and nearby ecologically similar habitats should be identified and designated as marine protected areas to mitigate effects of such disturbance.
