Fungal Genus

The fungal genus Agaricus includes edible, medicinal and some toxic species mainly in the Agaricus sect. Xanthodermatei. As the diversity of the genus is not well known in Iran, an inventory of the species has begun in 2013 in different provinces. Morphological and/or molecular analyses of 12 selected specimens from recent field collections and from herbarium specimens revealed that ten of them belonged to four potentially poisonous species of the Agaricus sect. Xanthodermatei: A. iodosmus, A. moelleri, A. phaeolepidotus and A. xanthodermus. Moreover, our study revealed that previous first records of A. xanthodermus and A. moelleri in Iran had been based on morphologically misidentified and correctly identified specimens, respectively. Finally, three species, A. iodosmus, A. phaeolepidotus and A. xanthodermus are reported as new records for Iran mycobiota. The four species of the section are described and illustrated.

From May to October 2017 seaweeds were identified in the field and laboratory from 20 sites around Brier Island, Nova Scotia. While most sites were intertidal rocky shores, there were one small salt marsh and one eelgrass bed included in the study, and some subtidal sampling was conducted utilizing SCUBA and snorkeling. The Brier Island seaweeds comprised 152 species and varieties of which 62 were Rhodophyta, 44 were Chlorophyta, 44 were Phaeophyceae, and two species were Xanthophyceae. Three species were new records for eastern Canada: Colaconema bonne- maisoniae, C. endophyticum, and Elachista stellaris, all were pre- viously recorded from New England. The flora included eight non- native species of which Colpomenia peregrina and Bonnemaisonia hami- fera (both gametophytic and tetrasporophytic stages) were abundant at two or more sites, and the invasive Codium fragile subsp. fragile was recorded based on a single drift specimen. With 150 species and varieties of seaweeds, Brier Island has the highest species richness of a limited area of eastern Canada. The Cheney floristic index at 2.4 is higher than comparable areas, and suggests that many additional brown algae remain to be found.Keywords: Chlorophyta, Colaconema, Bay of Fundy, Brier Island, Phaeophyceae, Rhodophyta, seaweeds

Two pasiphaeid shrimps, Leptochela (Leptochela) irrobusta Chace, 1976 and Leptochela (Leptochela) chacei Hayashi, 1995, were collected in samples from the South China Sea, marking the first time these species have been found in Chinese waters and thus as Chinese fauna. These two pasiphaeid species belong to the genus Leptochela Stimpson, 1860. L. (L.) chacei was previously known to be distributed in tropical regions: Viet-Nam, New Caledonia and Madagascar. This paper represents its first record from a temperate zone, which is unusual for its habitation. These two species are redescribed in detail and their current zoogeographical distributions are discussed. In addition to these two species, five species of Leptochela have previously been recorded from China. We used these species to provide a key to the Leptochela species from China.
