Two new species ofInocybe, sectionMarginatae (Agaricales, Cortinariaceae) from Japan

Two new species of the sectionMarginatae are described, namely,Inocybe populea sp. nov. andI. leptoclada sp. nov., from western Japan and eastern Japan, respectively.Inocybe leptoclada is assigned to sectionMarginatae, even though it lacks a marginate bulb.Inocybe populea is placed in the sectionMarginatae because of the presence of a marginate (often indistinct) bulbous base of stipe and the caulocystidia throughout. The discoveries ofI. leptoclada andI. populea provide further evidence that sectionMarginatae and sectionInocybe [=Cortinatae] are poorly defined.     

Notes on the genus Inocybe of Japan: I

 Three species of the genus Inocybe are reported as new species or new records from Japan. Inocybe phaeodisca Kühner var. geophylloides Kühner is redescribed by specimens collected in Chiba Prefecture; this is the first record of I. phaeodisca var. geophylloides for Japan. Inocybe pseudoreducta Stangl & Glowinski is also redescribed by materials collected in Hokkaido and Chiba Prefecture, new to Japan. Inocybe subtilis Takahito Kobayashi sp. nov. is proposed for material collected from Tokyo. The sectional position of this species is noted.

Notes on the genus <Emphasis Type="Italic">Inocybe</Emphasis> of Japan. IV. Species having metuloids collected from Hokkaido,Honshu, and Kyushu

This fourth paper in the series considers five species of Inocybe occurring in Hokkaido, Honshu, and Kyushu. (1) Inocybe furfurea (section Tardae) is recorded from Hokkaido as new to Japan. (2) Inocybe luteola sp. nov. (section Tardae) is described from eastern Honshu (Chiba). It has smooth basidiospores and thick-walled caulocystidia descending to the middle of the stipe. (3) Inocybe napiformis sp. nov. [section Inocybe (= Cortinatae)], known from Hokkaido, appears close to Inocybe napipes, but characters of the metuloids distinguish the two species. (4) Inocybe grammata (section Marginatae) is recorded from Hokkaido and Nagano as new to Japan. (5) Inocybe pyriformis sp. nov. (section Marginatae) is described from Kyushu (Miyazaki). It has nodulose basidiospores and caulocystidia wholly covering the stipe surface. However, I. pyriformis is not typical in the section, lacking a marginate bulbous base in its stipe.     

Inocybe nitidiuscula, new to Japan

A species of the genus Inocybe, which has not been recorded previously in Japan, is described and illustrated as a new record. Inocybe nitidiuscula (Britzelm.) Sacc. belongs to the subgenus Inocibium (Earle) Singer.     

A new species of <Emphasis Type="Italic">Gymnopilus</Emphasis> Sect. <Emphasis Type="Italic">Microspori</Emphasis> from Japan

It is characterized by its medium-sized, brownish-orange basidiocarps with a finely squamulose pileus, stipe lacking an annulus, and mild taste, and microscopically by dextrinoid, small, broadly ellipsoid basidiospores. The new species belongs to the section Microspori. The differences between the taxon and similar species are briefly discussed.

中国毛霉目的一个新纪录属—单囊霉属

单囊霉属(Haplosporangium)是被孢霉科(Mortierellaceae)内的一个小属,由Thaxter在1914年建立的。它的主要特征为孢囊梗从高度分化、通常分隔的菌丝上长出。本文首次在中国报道了两个种(极尖单囊霉Haplosporangium attenuatissima sp. nov.和单孢单囊霉H.decipens Thaxter),其中极尖单囊霉是新种,其特征为孢囊梗基部强烈膨大、顶端极细,孢子囊内含1-9个孢子。     

A new species of <Emphasis Type="Italic">Cortinarius</Emphasis> sect. <Emphasis Type="Italic">Orellani</Emphasis> from Japan

Cortinarius breviradicatus sp. nov., found in deciduous forests, is described and illustrated from Niigata, Japan. It is characterized by its medium-sized to large dark brown basidiocarp, acutely conical pileus, and rooting stipe, and by subglobose to broadly ellipsoid basidiospores. In addition, the extracting solution from its basidiocarps exhibits a strong fluorescence around 400–430 nm in ultraviolet radiation (250 nm), which was observed in a species of Cortinarius sect. Orellani. The new species belongs to the section Orellani. The differences between the new taxon and similar species are briefly discussed.

New species and a new combination in the <Emphasis Type="Italic">Hyphopichia</Emphasis> and <Emphasis Type="Italic">Yarrowia</Emphasis> yeast clades

Three new species of Candida and a new combination in the genus Hyphopichia are proposed from phylogenetic analysis of nucleotide divergence in domains D1/D2 of the large subunit (26S) rDNA. The new taxa and their type strains are the following: Candida bentonensis sp. nov. (NRRL YB-2364, CBS 9994), Candida hispaniensis sp. nov. (NRRL Y-5580, CBS 9996), Candida pseudorhagii sp. nov.

Taxonomic review of the genus <Emphasis Type="Italic">Cottiusculus</Emphasis> (Cottoidei: Cottidae) with description of a new species from the Sea of Japan

A taxonomic review of the cottid genus Cottiusculus Jordan and Starks 1904 established three species, C. nihonkaiensis sp. nov., C. schmidti, and C. gonez. Cottiusculus nihonkaiensis sp. nov., which had been previously confused with C. schmidti, is described on the basis of 32 specimens (44.8–77.9 mm, SL) collected from the Sea of Japan. The new species is very similar to C. schmidti in having a curved barbless uppermost preopercular spine and the lateral line extending past the caudal fin base, but is distinguishable as follows: nasal spines simple or sometimes weakly bicuspid (vs. deeply bicuspid in C. schmidti); first dorsal fin not elongated in either males or females (vs. elongated in males); ventral lateral and lateral line cirri present (vs. absent). The former is known from the Sea of Japan coasts of Hokkaido, Honshu, Kyushu and the Korean Peninsula, and Volcano Bay, Hokkaido, and the latter from the Pacific coast of Tohoku District, Japan. Cottiusculus gonez, known from the Sea of Japan, Sea of Okhotsk and Pacific coast of Hokkaido, is characterized by having a simple nasal spine, the uppermost preopercular spine almost straight with two small cusps dorsally, posterior cusp barbed, and the lateral line almost reaching to the caudal fin base. A lectotype of C. gonez is designated here. Sequence differences in the cytochrome b gene among the above three species of Cottiusculus are also presented.
