A new species Chlorolepiota indica is reported from Patiala in Punjab, India. The fungus is characterized by convex brown pileus covered by concentrically arranged brown scales with yellow tinge around the umbo. The stipe of the fruiting body is cream to pale yellow, pinkish to reddish brown near the pileus, and yellowish to dark grey brown towards the base.     

Gymnopus piceipes sp. nov. from Japan

Gymnopus piceipes is proposed as a new species within the sectionVestipedes. It is characterized by a brown pileus, pale brown close lamellae, a solid black stipe that is not insititious, and conspicuous pleurocystidia.     

Lepiota vellingana sp. nov. (Basidiomycota, Agaricales) a new species from Lahore, Pakistan

A new species of Lepiota, L. vellingana, is described and illustrated from Lahore, Pakistan. It is characterized by a campanulate to plano-convex, slightly umbonate, white pileus covered with pinkish brown scales, crowded lamellae, guttulate basidiospores, long trichodermial stipe elements, and long trichodermial pileal elements.     

A new species of Lactarius (subgenus Gerardii) from two relict Fagus grandifolia var. mexicana populations in Mexican montane cloud forests

A new milkcap species, Lactarius fuscomarginatus, was found in the subtropical region of central Veracruz (eastern Mexico) associated with two relict populations of Fagus grandifolia var. mexicana. The species is characterized macroscopically by its dark pileus and stipe and by its distant and whitish lamellae with blackish to blackish brown edges. A molecular phylogenetic analyses based on ITS and LSU nucDNA sequences confirms the delimitation of this new taxon and places L. fuscomarginatus in subgenus Gerardii. A detailed morphological comparison is given with similar species.     

Pluteus aurantipes sp. nov. from Wisconsin, United States

Pluteus aurantipes sp. nov. was discovered in Wisconsin, United States. This agaric species is characterized by its yellowish brown pileus, reddish orange stipe, pileipellis consisting of a trichoderm and lack of pleurocystidia.     

New species of <Emphasis Type="Italic">Austroboletus</Emphasis> (Boletaceae) in Australia

Three new species of Austroboletus are described from Australia. Austroboletus austrovirens has been collected repeatedly in northern Queensland and the Northern Territory, and is primarily distinguished by its dry, green pileus and stipe ornamentation, and boletoid spores with meandering ridges and pits. Austroboletus viscidoviridis is known from southeastern coastal Queensland and Cape Tribulation; it is recognized by a glutinous-viscid, olive-green pileus, brown reticulum on the stipe, and amygdaliform spores with nodulose-tuberculate ornamentation. Austroboletus roseialbus has only been collected in eastern New South Wales and is characterized by a white pileus with subtle rosy tints, and flattened, white, lanose patches; the spores are amygdaliform with irregular alveolate-reticulate ornamentation.     

A new genus of Boletaceae from eastern North America

Bothia is described as a new genus in the Boletaceae based on Boletinus castanellus described by C.H. Peck from eastern North America. A widespread, occasionally encountered taxon, Bothia castanella possesses a combination of macro- and microscopic features that has prompted past placement in seven different genera. Yet, as a species it is readily recognizable with its chestnut brown, dry pileus, decurrent, pale brown hymenophore with radially elongated tubes, a short, sometimes eccentric, exannulate stipe, yellow brown spore deposit and constant association with Quercus. Phylogenetic analyses of large subunit rDNA and BLAST searches using the ITS region confirm the placement of B. castanella as a unique generic lineage in the Boletaceae.     

Notes on new Agaricales of Japan 2

Three new species of Agaricales are described and illustrated from eastern Honshu, Japan:Boletus rhodocarpus sp. nov. (sectionLuridi), forming large, deep red basidiomata with a pileus covered with small, blackish brown scales, was found on ground in a highland forest dominated byTsuga diversifolia andAbies veitchii; Phaeomarasmius laccarioides sp. nov. (subgenusCarpophilus), forming a squamulose-fibrillose, reddish brown pileus in which the pileipellis consists of chains of thick-walled sphaerocysts with heavily incrusting, brown pigment, was found on a fallen fruit ofLiquidambar styraciflua; Pluteus phaeocephalus sp. nov. (subsectionHispidodermini of sectionCelluloderma), forming a dark brown, velvety pileus and a white stipe densely covered with dark brown punctate scales, was found on dead fallen twigs ofQuercus serrata.     

A new species of Amanita section Lepidella from South China

Amanita macrocarpa from Guangdong Province of China is described. The new species is a large, brownish orange to light brown mushroom, characterized by numerous pyramidal warts on the pileus, yellowish lamellae, a large annulus at the middle of the stipe, and amyloid ellipsoidal basidiospores. Phylogenetic analyses of the new species and related taxa based on the large subunit of nuclear ribosomal DNA (LSU) and the internal transcribed spacer (ITS) sequences are provided. Morphological and molecular data show that A. macrocarpa is a member of Amanita, section Lepidella, and clearly different from any known taxon of the section.
