Effects of Consuming Pulsed UV Light-Treated on Vitamin D Nutritional Status in Healthy Adults.

Vitamin D, essential for growth and health, is often deficient in Taiwan despite abundant sunlight. Plant-derived vitamin D (ergocalciferol) is bioavailable, environmentally friendly, and cost-effective. This study evaluated the efficacy of enhancing (PC) mushrooms' vitamin D content through pulsed ultraviolet (PUV) light and its impact on vitamin D status in humans.

Xylaria iriomotensis sp. nov. from termite nests and notes on X. angulosa.

Background: Fungus gardens of the termite Odontotermes formosanus, excavated from Iriomote Island, Okinawa Prefecture, Japan, were subsequently incubated under laboratory conditions. A Xylaria species emerging from these fungus gardens was initially identified as X. angulosa, a species originally described from North Sulawesi, Indonesia.

Five new Camillea (Xylariales) species described from French Guiana.

Background: The genus Camillea was created in 1849 from collections made in French Guiana with eight species included. Numerous species assigned to Camillea were subsequently discovered, especially in the forests of the Amazon basin, but new discoveries have not been reported from French Guiana since 1849. Recent fieldwork in French Guiana has begun to fill this gap by identifying five new species, most of which were collected in the vicinity of Saül village.

Xylaria furcata reconsidered and nine resembling species.

Background: Xylaria collections from termite nests with dichotomously branched stromata have been identified as X. furcata. However, Léveillé's original material is no longer available, and the modern interpretation of X.

Xylaria species associated with fallen leaves and petioles.

Background: Xylaria species growing on fallen leaves and petioles have not been treated systematically. One source of confusion in this group of Xylaria species has stemmed from X. filiformis, which is an ancient name published in 1805 as Sphaeria filiformis and has commonly labeled on specimen packets that contain leaf- and petiole-inhabiting Xylaria species.

Medicinal Components in Edible Mushrooms on Diabetes Mellitus Treatment.

Mushrooms belong to the family "Fungi" and became famous for their medicinal properties and easy accessibility all over the world. Because of its pharmaceutical properties, including anti-diabetic, anti-inflammatory, anti-cancer, and antioxidant properties, it became a hot topic among scientists. However, depending on species and varieties, most of the medicinal properties became indistinct.

Polyketides with Anti-neuroinflammatory Activity from .

89091602 is a previously reported plant-derived bioactive fungal strain, and the active principles separated from the extracts of its submerged culture were shown to exhibit potent anti-neuroinflammatory activities in both cellular study and animal testing. In a continuation of our previous investigation on the bioactive entities from this fungus, solid state fermentation was performed in an attempt to diversify the bioactive secondary metabolites. In the present study, five previously unreported polyketides, theissenophenol (), theissenepoxide (), theissenolactone D (), theissenone (), and theissenisochromanone (), together with the known theissenolactone B (), theissenolactone C (), and arthrinone (), were isolated and characterized through spectroscopic analysis and comparison with the literature data.

Xylaria insolita and X. subescharoidea: two newly described species collected from a termite nesting site in Hua-lien, Taiwan.

Background: A number of Xylaria species are exclusively associated with nests of macrotermitine termites. A nesting site of Odontotermes formosanus in eastern Taiwan, which is the only macrotermitine termite known on the island, had been inundated during the raining season of 2010, and hundreds of Xylaria stromata emerged from it thereafter. A thorough examination of these stromata showed that they represent a mixture of different species.

Isoprenyl phenolic ethers from the termite nest-derived medicinal fungus Xylaria fimbriata.

Seven new isoprenyl phenolic ethers, namely fimbriethers A‒G (1‒7), were isolated from the fermented broth of the termite nest-derived medicinal fungus Xylaria fimbriata YMJ491.

Twenty-five fructicolous and seminicolous species of Xylaria are classified into three groups by stromatal morphology: (i) the X. ianthinovelutina group; (ii) the X. carpophila group; and (iii) the X.

Medicinal components in Termitomyces mushrooms.

Termitomyces is a genus of edible mushrooms commonly consumed in Africa and Asia among the mushrooms collected from the wild. Termitomyces mushrooms grow as symbionts in the termite nests, where they produce various enzymes to help termites digest lignocellulosic substrates. Many species of Termitomyces are used by different ethnic groups with ethnomedicinal knowledge.

A termite symbiotic mushroom maximizing sexual activity at growing tips of vegetative hyphae.

Background: Termitomyces mushrooms are mutualistically associated with fungus-growing termites, which are widely considered to cultivate a monogenotypic Termitomyces symbiont within a colony. Termitomyces cultures isolated directly from termite colonies are heterokaryotic, likely through mating between compatible homokaryons.

Results: After pairing homokaryons carrying different haplotypes at marker gene loci MIP and RCB from a Termitomyces fruiting body associated with Odontotermes formosanus, we observed nuclear fusion and division, which greatly resembled meiosis, during each hyphal cell division and conidial formation in the resulting heterokaryons.

The survey of tinea capitis and scalp dermatophyte carriage in nursing home residents.

Tinea capitis is a contagious dermatophyte infection of scalp and associated hairs. On the other hand, asymptomatic carriage is a status of positive dermatophyte scalp culture, but without signs or symptoms of tinea capitis, and no evidence of hair shaft invasion confirmed by direct microscopy. Tinea capitis and asymptomatic carriage mostly occur in children, but adult females are becoming another population in recent decades.

Small agarics in Taiwan: Mycena albopilosa sp. nov. and Gloiocephala epiphylla.

Background: Small agarics are poorly documented in Taiwan, with previously reported species either rudimentarily described or lacking a description or diagnosis in most cases. A survey on small agarics in a lowland forest of Taiwan revealed two species previously unrecorded.

Results: One agaric, which is characterized mainly by white hairs overlying the pileus, a conspicuous cup-shaped basal disc surrounding the stipe, and inamyloid basidiospores, fits the genus Mycena and appears undescribed.

Recommendations for competing sexual-asexually typified generic names in Sordariomycetes (except Diaporthales, Hypocreales, and Magnaporthales).

With the advance to one scientific name for each fungal species, the generic names in the class Sordariomycetes typified by sexual and asexual morphs are evaluated based on their type species to determine if they compete with each other for use or protection. Recommendations are made for which of the competing generic names should be used based on criteria such as priority, number of potential names changes, and frequency of use. Some recommendations for well-known genera include Arthrinium over Apiospora, Colletotrichum over Glomerella, Menispora over Zignoëlla, Microdochium over Monographella, Nigrospora over Khuskia, and Plectosphaerella over Plectosporium.

Two rare ophiocordycipitaceous fungi newly recorded in Taiwan.

Background: Ophiocordycipitaceae is a highly diverse fungal family parasitizing a wide range of arthropods and hypogeous fungi. We collected two ophiocordycipitaceous species previously unknown in Taiwan: one emerged from hypogeous fruiting bodies of an Elaphomyces fungus and the other was associated with dragonflies.

Results: Based on gross morphology, microscopic features, ITS sequences, and hosts, the two ophiocordycipitaceous fungi were identified as Tolypocladium japonicum and Ophiocordyceps odonatae.
