“…Field efforts to obtain material from the co-distributed species Fagus japonica as an alternative host (Fang and Lechowicz 2006) have been unsuccessful. In addition to the well-known host specificity in many species of Lachnaceae (e.g., Tochihara and Hosoya 2019), overall this provides further evidence of the strong ecological relationship between D. longistipitata and F. crenata.…”

During the Last Glacial Maximum (LGM), drastic environmental changes modified the topology of the Japanese Archipelago, impacting species distributions. An example is Fagus crenata, which has a present continuous distribution throughout Japan. However, by the end of the LGM it was restricted to southern refugia. Similarly, Dasyscyphella longistipitata (Leotiomycetes, Helotiales, Lachnaceae) occurs strictly on cupules of F. crenata, sharing currently an identical distribution. As the effects of the LGM remain poorly understood for saprobiotic microfungal species, herein we identified past structuring forces that shaped the current genetic diversity within D. longistipitata in relation to its host using a phylogeographic approach. We inferred present and past potential distributions through species distribution modeling, identifying environmental suitability areas in mid-southern Japan from which subsequent colonizations occurred. Our findings suggest that current high genetic diversity and lack of genetic structure within D. longistipitata are the result of recent multiple re-colonization events after the LGM.

“…In the cecal lumen at day 1, fed samples consisted mainly of Gibberella (83%), while unfed communities were composed of Incrucipulum (32%), Cladosporium (25.4%), Coniochaeta (14%), and unidentified Fungi (11%). Incrucipulum and Coniochaeta are environmental taxa, with Incrucipulum often associated with fallen leaves or twigs ( Tochihara and Hosoya, 2019 ), and Coniochaeta found on diverse substrates including soil, plants, butter, and feces ( Si et al, 2021 ). At day 2 Gibberella remained low (4%), Incrucipulum dropped to less than 1%, and Coniochaeta , unidentified Fungi, and Cladosporium comprised the majority of the remainder of the samples.…”

Temporal dynamics of the chicken mycobiome

et al. 2022

The microbiome is an integral part of chicken health and can affect immunity, nutrient utilization, and performance. The role of bacterial microbiota members in host health is relatively well established, but less attention has been paid to fungal members of the gastrointestinal tract (GIT) community. However, human studies indicate that fungi play a critical role in health. Here, we described fungal communities, or mycobiomes, in both the lumen and mucosa of the chicken ileum and cecum from hatch through 14 days of age. We also assessed the effects of delayed access to feed immediately post-hatch (PH) on mycobiome composition, as PH feed delay is commonly associated with poor health performance. Chicken mycobiomes in each of the populations were distinct and changed over time. All mycobiomes were dominated by Gibberella, but Aspergillus, Cladosporium, Sarocladium, Meyerozyma, and Penicillium were also abundant. Relative abundances of some taxa differed significantly over time. In the cecal and ileal lumens, Penicillium was present in extremely low quantities or absent during days one and two and then increased over time. Meyerozyma and Wickerhamomyces also increased over time in luminal sites. In contrast, several highly abundant unclassified fungi decreased after days one and two, highlighting the need for improved understanding of fungal gut biology. Mycobiomes from chicks fed during the first 2 days PH versus those not fed during the first 2 days did not significantly differ, except during days one and two. Similarities observed among mycobiomes of fed and unfed chicks at later timepoints suggest that delays in PH feeding do not have long lasting effects on mycobiome composition. Together, these results provide a foundation for future mycobiome studies, and suggest that negative health and production impacts of delayed feeding are not likely related to the development of fungal populations in the GIT.

“…For the five species of Microstoma known in Japan, sequences were derived from specimens at the TNS herbarium. DNA was extracted from mycelia cultivated on 2% (w/v) malt extract broth (Bacto TM Malt Mycoscience: Advance Publication A d v a n c e P u b l i c a t i o n Extract; Thermo Fisher Scientific, Waltham, MA, USA) following the modified CTAB method (Hosaka & Castellano, 2008;Tochihara & Hosoya, 2019). When isolates were not available, DNA was extracted from pieces of dried apothecia using the same method.…”

“…When isolates were not available, DNA was extracted from pieces of dried apothecia using the same method. The ITS-5.8S region was then amplified, sequenced, and aligned following procedures described by Tochihara and Hosoya (2019) . Aligned sequences were deposited in the DNA Data Bank of Japan (DDBJ) ( Table 1 ).…”

Microstoma longipilum sp. nov. collected from two localities in Japan is described. It is characterized by long apothecial hairs and salmon pink discs. Molecular phylogenetic analyses supported the novelty of the fungus. We additionally reported the overlooked morphology of hyphal mats, conidiogenous cells produced directly from ascospores, and conidia. With the addition of M. longipilum, now six species of Microstoma are documented in Japan.
