A New Species

Xanthagaricus siamensis, a new species in the family Agaricaceae, was discovered in northern Thailand and is here introduced based on its morphological features and molecular data. It is characterized by small to medium-sized basidiomata, a convex to plano-convex with depressed center pileus when mature, the presence of greyish orange to violet-brown fibrillose squamules on the pileus, lamellae that start out white, change to pinkish white when damaged, then change to dull green with age. Additionally, the annulus is fugacious, and the pileipellis is recognized as a cutis which morphologically distinguishes it from all other known Xanthagaricus. Phylogenetic analysis of the internal transcribed spacer region (ITS) and the large subunit of the nuclear ribosomal DNA (nrLSU) sequence data indicated that the three specimens of X. siamensis form a distinct lineage within Xanthagaricus, and they formed a well-supported clade representing the genus Xanthagaricus. Detailed illustrations of macro- and micro-morphological characteristics and descriptions are provided, as well as other relevant molecular evidence.

A New Species

Gibellula is an exclusively spider-pathogen genus, with most species immediately recognized by their distinctive conidial state, but also including the teleomorphic states of these fungi that were previously included in the rejected genus Torrubiella. Two sexual specimens and an asexual morph specimen were collected from Anhui Province, China, and were recognized as the same species based on molecular evidence. Its asexual morph differs from Gibellula pulchra, to which it is morphologically similar, in having shorter verrucose conidiophores with slightly smaller metulae, phialides and conidia. Its sexual morph is characterized by producing superficial and elongate ellipsoid small perithecia with short asci on a cream-yellow mycelial mat covering the host. Multi-locus (SSU, LSU, TEF, and RPB1) phylogenetic analyses showed that the specimens belong to a strongly supported subclade, and formed a sister subclade with G. pulchra and Gibellula sp. A combination of morphological characteristics and its phylogenetic placement confirmed that these unique specimens are a new species, which is described as Gibellula flava.

Taxonomic System

Agaricus is a species-rich genus with more than 500 species over the world. Recent studies on tropical Agaricus revealed new tropical clades and a revised taxonomic system was consequently developed. Agaricus subg. Minoriopsis, a sixth subgenus was recently added, comprising species exclusively from the Americas. The diversity of Agaricus is little studied in Mexico, despite this country has a long history in the consumption of wild edible fungi. In this paper, we introduce a new species A. guzmanii and a new record for A. globocystidiatus from Mexico based on morphological characteristics and molecular data. Phylogenetic analyses indicate that they belong to A. subg. Minoriopsis.

A New Species

The identification of Auricularia species has previously relied on the examination of macroscopic features of mushroom samples collected in Thailand. These features may vary with age, light exposure, moisture and other factors, making such identification prone to error. This study uses morphological characteristics and molecular data to improve upon previous classifications of Auricularia species. Fruiting bodies collected during recent field excursions and previous collections from herbaria were examined and sequenced for two loci, viz. ITS and rpb2. Auricularia asiatica is described as a new species based on both morphological characteristics and molecular data, and is introduced with a full description, illustrations and colour photographs. Auricularia cornea and A. villosula are described as new records from Thailand. A combined ITS and rpb2 phylogenetic tree is provided, showing the placement of five Auricularia species found in Thailand.

A New Species

A phylogeny of all nine subgenera of Drosanthemum, based on chloroplast sequence-data, is presented. The results confirm some previously published facts, e.g. that D. zygophylloides is sister to Drosanthemum. We propose to treat this species as a new monotypic genus, Lemonanthemum, which differs from Drosanthemum in features of the leaves and fruit-stalks. In Drosanthemum s.s., the small subg. Quadrata, characterized by 4-locular fruits, is highly supported as sister to the remainder of Drosanthemum (where fruits are 5-locular). Further, our data support the transfer of Delosperma pubipetalum to Drosanthemum (where a nomenclatural change is also made). The pubescent petals, 5-locular fruits with narrow covering membranes and downward-pointing hair-like papillae on the branches suggest that D. pubipetalum is close to D. papillatum and belongs to subg. Quastea. Another species, D. badspoortense, which had been placed in D. subg. Quastea on account of its narrow covering membranes, is shown to belong to Delosperma and also lacks the unique structure of the fruit-stalk of Drosanthemum. In addition, a new species, D. overbergense, is described from disjunct patches of remnant renosterveld within the Overberg and near Albertinia, in the Western Cape of South Africa. Morphological characteristics suggest that this species belongs to subg. Xamera, but this was not corroborated by our molecular data. Finally, a new name—Drosanthemum calcareum—is proposed for the illegitimate D. intermedium and a lectotype (at BOL) is designated for D. pubipetalum. The lectotypification of D. badspoortense is also proposed.
