Twenty species of thermophilous fungi were identified from sugarcane bagasse at Batala in Northern India. Seven fungal species are reported from bagasse for the first time and Aspergillus caespitosns is a new record for India. Aspergillus fumigatus was the most common fungus followed by Mncor pusillus. The temperature responses of the fungi revealed 5 microthermophiles, 11 thermotolerant, and 4 true thermophiles. Three species of thermophilous fungi are reported in addition to those already recorded in the literature.

During the survey of wild edible mushrooms in between tropical and temperate belt of Nepal in rainy season 2010 -2012, many macro fungal species were collected and identified. The paper highlights on new record of Volvorella taylorii (Berk and Broome) Sing. The species was reported and re-described for the first time from Nepal. Along with, taxonomic description of the two species of Volvorella found in the same studied area, have also been provided. Phytogeographycally, the sample collected area lies within a narrow limit of 9.75 hectare at the altitude between 335 and 400 masl in tropical deciduous riverine forest. The dried specimens are housed in the Tribhuvan University Central Herbarium (TUCH), Kirtipur Kathmandu, Nepal.

We report the powdery mildew Golovinomyces ambrosiae for the first time on silverleaf nightshade (Solanum azureum), a host plant endemic to northern Sinaloa and southern Sonora, Mexico. No teleomorph was observed, requiring the fungal species to be identified based on morphological characteristics of the anamorph. Phylogenetic analyses of the ITS region and the partial sequence of the β-tubulin gene from four specimens confirmed the identity of the species. To our knowledge, this is the first report of G. ambrosiae on S. azureum in Mexico and worldwide.

Buellia epigaea, a terricolous lichenized fungal species known from numerous localities in Northern Hemisphere, but only from Australia in Southern Hemisphere, is reported from Antarctica for the first time. Here we provide morphological, anatomical, and molecular characteristics (nrITS) of this species. Besides, the differences of B. epigaea with morphologically, ecologically or phylogenetically related species are discussed.

Abstract After chemical pretreatment, improved amenability of agrowaste biomass for enzymatic saccharification needs an understanding of the effect exerted by pretreatments on biomass for enzymatic deconstruction. In present studies, NaOH, NH4OH and H2SO4 pretreatments effectively changed visible morphology imparting distinct fibrous appearance to sugarcane bagasse (SCB). Filtrate analysis after NaOH, NH4OH and H2SO4 pretreatments yielded release of soluble reducing sugars (SRS) in range of ~0.17–0.44%, ~0.38–0.75% and ~2.9–8.4% respectively. Gravimetric analysis of pretreated SCB (PSCB) biomass also revealed dry weight loss in range of ~25.8–44.8%, ~11.1–16.0% and ~28.3–38.0% by the three pretreatments in the same order. Release of soluble components other than SRS, majorly reported to be soluble lignins, were observed highest for NaOH followed by H2SO4 and NH4OH pretreatments. Decrease or absence of peaks attributed to lignin and loosened fibrous appearance of biomass during FTIR and SEM studies respectively further corroborated with our observations of lignin removal. Application of commercial cellulase increased raw SCB saccharification from 1.93% to 38.84%, 25.56% and 9.61% after NaOH, H2SO4 and NH4OH pretreatments. Structural changes brought by cell wall degrading enzymes were first time shown visually confirming the cell wall disintegration under brightfield, darkfield and fluorescence microscopy. The microscopic evidence and saccharification results proved that the chemical treatment valorized the SCB by making it amenable for enzymatic saccharification.

The genus Agrisius Walker (1855) is reported for the first time in Cambodia, for the new species Agrisius nigripunctata sp. n. Additionally, Agrisius fuliginosus is reported for the first time in Laos, Myanmar, China, Thailand and Vietnam. Illustrations of the adult and genitalia of Agrisius nigripunctata sp. n. and A. fuliginosus Moore are presented.

Establishment of a fungal infection due to Aspergillus fumigatus relies on the efficient germination of the airborne conidia once they penetrate the respiratory tract. However, the features of conidial germination have been poorly explored and understood in this fungal species as well as in other species of filamentous fungi. We show here that the germination of A. fumigatus is asynchronous. If the nutritional environment and extensive gene deletions can modify the germination parameters for A. fumigatus, the asynchrony is maintained in all germinative conditions tested. Even though the causes for this asynchrony of conidial germination remain unknown, asynchrony is essential for the completion of the biological cycle of this filamentous fungus.

Two new species and one new record species of the genus Pseudonereis are described from specimens collected from ecological surveys of coasts of Taiwan and an offshore island during the past 15 years: P. jihueiensis n. sp., P. kihawensis n. sp., and P. trimaculata. Epitokes of P. jihueiensis n. sp. and P. trimaculata are also described. Pseudonereis jihueiensis n. sp. can be distinguished from congeners by having edentate jaws, χ-shaped ridge pattern of Areas VI–V–VI, parapodial morphology (i.e., length ratio of dorsal cirrus to dorsal ligule or presence of small pennant-like dorsal ligule, shape of dorsal ligule in certain region of chaetigers), and no heterogomph spinigers in the subacicular fascicle of the neuropodia. Pseudonereis kihawensis n. sp. differs from congeners by having crescent-shaped pointed-bars in Area VI, λ-shaped ridge pattern of Areas VI–V–VI, parapodial morphology (i.e., length ratio of dorsal cirrus to dorsal ligule or presence of small pennant-like dorsal ligule or shape of dorsal ligule in certain region of chaetigers), and no heterogomph spinigers in the subacicular fascicle of the neuropodia. Pseudonereis trimaculata, a species originally described from Indonesia, is reported from Taiwan for the first time. A table of key characters for all species of Pseudonereis is provided.
