The present study reports the identification of two newly recorded species of the genus Rickenella, R. indica and R. mellea, in Japan. Small (1-3 mm wide), parabolic to convex, and never becoming applanate or infundibuliform pileus are characteristic features of R. indica. Rickenella mellea is a subalpine species and it is characterized by its honey-colored, yellowish-beige to reddish yellow-pileus and stipe. Molecular phylogenetic analysis using the ITS region and the LSU of the nuclear rDNA supported their identification based on morphological observations. A key to the known Japanese species of Rickenella and morphologically similar taxa is provided.

The discovery of novel natural products through the exploration of distinctmicroorganisms is crucial for advancing drug discovery research. In this study, we focus on a unique environmental resource, microbial masses known as “Tengu-no-Mugimeshi.” From the culture broth of Lecanicillium aphanocladii FKI-9593, isolated from Tengu-no-Mugimeshi collected at Mount Kurohime, Nagano Prefecture, Japan, we report the isolation of two novel tetrapeptides, tengupeptins A (1) and B (2), as well as the known compound oosporein. Structural analysis revealed that tengupeptins are composed of four amino acids: L-glutamic acid for 1 (or L-pyroglutamic acid for 2), (Z)-α,β-didehydro tryptophan (ΔZTrp), (Z)-α,β-didehydro-phenylalanine (ΔZPhe), and L-aspartic acid. Notably, dehydroamino acids containing an aromatic moiety conjugated with a double bond connected via two or more consecutive linkages are rare in natural products, and the ΔZTrp-ΔZPhe fragment represents the first example. The isolation of secondary metabolites from filamentous fungi inhabiting unique environments, such as Tengu-no-Mugimeshi, is anticipated to offer significant potential for future research.

Gymnosporangium mori comb. nov. (Pucciniales) for Caeoma mori (≡ Aecidium mori) inferred from phylogenetic evidence

Caeoma mori (≡ Aecidium mori), known as the mulberry rust which is an anamorphic rust fungus forming only aecidioid uredinia, were found on Morus alba in Ibaraki and Saitama Prefectures, Japan. Molecular phylogenetic analyses using the combined dataset of sequences from 28S and 18S of the nuclear ribosomal RNA gene and Cytochrome-c-oxidase subunit 3 of the mitochondrial DNA revealed that this anamorphic rust fungus was a member of the clade composed of the genus Gymnosporangium. Therefore, a new combination, Gymnosporangium mori is proposed for this species. Additionally, a new combination, G. brucense for Roestelia brucensis is proposed by phylogenetic evidence.

A subhypogeous sclerodermataceous fungus was collected in Nagoya, Aichi Prefecture, central Japan. Based on morphological observations and phylogenetic analyses using nuclear ribosomal DNA sequences, the present fungus was identified as Scleroderma yunnanense, belonging to Sclerodermataceae (Boletales). Scleroderma yunnanense is new to Japan and characterized by not stellately dehiscent basidiomata when mature, thick (2–7 mm) peridium covered by cream to pale yellowish scales, basidiomata covered with whitish mycelial strands, clamped hyphae, and globose to subglobose basidiospores densely covered with pyramidal warts.

Hydropodia silvae-nipponicae, a new agaric species was described based on the specimens collected from evergreen broad-leaved forests in Japan. The present new species is distinct from H. subalpina, the type species of the genus by morphological characteristics and nuclear rDNA sequences. Hydropodia silvae-nipponicae is characterized by its nodulose cystidium-like terminal elements of pileipellis, cylindrical to clavate pileocystidia with irregular excrescences, and dimorphic pleurocystidia. It is the second species belonging to the genus Hydropodia.
