Re-Evaluation of the Order Sordariales: Delimitation of Lasiosphaeriaceae s. str., and Introduction of the New Families Diplogelasinosporaceae, Naviculisporaceae, and Schizotheciaceae. Microorganisms 2020; 8:microorganisms8091430. [PMID: 32957559 PMCID: PMC7565071 DOI: 10.3390/microorganisms8091430] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Revised: 08/11/2020] [Accepted: 09/12/2020] [Indexed: 11/16/2022] Open
Abstract
The order Sordariales includes the polyphyletic family Lasiosphaeriaceae, which comprises approximately 30 genera characterized by its paraphysate ascomata, asci with apical apparati, and mostly two-celled ascospores, which have a dark apical cell and a hyaline lower cell, frequently ornamented with mucilaginous appendages. To produce a more natural classification of this family, we carried out a phylogenetic analysis based on sequences of the internal transcribed spacer region (ITS), the nuclear rDNA large subunit (LSU), and fragments of ribosomal polymerase II subunit 2 (rpb2) and β-tubulin (tub2) genes of several isolates from soil and of reference strains of the Sordariales. As a result, Lasiosphaeriaceae s. str. has been circumscribed for the clade including the type species of the genus Lasiosphaeria and, consequently, its description emended. In addition, the new families Diplogelasinosporaceae, Naviculisporaceae, and Schizotheciaceae are introduced to accommodate those taxa located far from the Lasiosphaeriaceae s. str. Moreover, we propose the erection of the new genera Areotheca, Lundqvistomyces, Naviculispora, Pseudoechria, Pseudoschizothecium, and Rhypophila based on morphological and sequence data. New combinations for several species of the genera Cladorrhinum, Jugulospora, Podospora, Schizothecium, and Triangularia are proposed, their descriptions are emended, and dichotomous keys are provided to discriminate among their species.

Fungal Diversity of Deteriorated Sparkling Wine and Cork Stoppers in Catalonia, Spain. Microorganisms 2019; 8:microorganisms8010012.

Abstract
Filamentous fungi are rarely reported as responsible for spoiling wine. Cork taint was detected in sparkling wine; therefore, we investigated fungal contamination as a possible cause of organoleptic alteration. Spoiled wine was filtered and membranes were plated onto potato dextrose agar (PDA). The cork stoppers used for sealing bottles were cut and also plated onto PDA. Fungal strains were phenotypically characterized and molecularly identified by sequencing of a fragment of the 28S nrRNA gene (LSU) and (occasionally) by other additional molecular markers. Twenty-seven strains were isolated and sixteen species were identified, all of them belonging to the phylum Ascomycota. The fungi isolated from wine were three species of Aspergillus section Nidulantes, a species of Penicillium section Exicaulis and Beauveria bassiana. Candida patagonica was isolated from both sort of samples, and the fungi isolated from cork stoppers were Altenaria alternata and Cladosporium cladosporioides. Surprisingly, most of the taxa recovered from the cork stoppers and/or wine were new to the science: a new genus (Dactylodendron) and seven new species belonging to the genera Cladophialophora, Dactylodendron, Kirschsteiniothelia, Rasamsonia, and Talaromyces. Future studies could let us know if these fungi would be able to produce compounds responsible for cork taint.

Abstract
This study contributes new knowledge on the diversity of conidial fungi in edible pine (Pinus armandii) seeds found in Yunnan Province, China and emphasizes the importance of edible seed products to ensure food safety standards. We isolated two fungal species, one on the pine seed coat and the other on the endosperm of the pine seed. The two fungal species were identified as Pestalotiopsis pinicola sp. nov. and a new host record Cladosporium anthropophilum. Characteristic morphological features of Pestalotiopsis pinicola were used alongside results from multi-gene phylogenetic analysis to distinguish it from currently known species within the genus. Cladosporium anthropophilum was identified as a new host record based on morphological features and phylogenetic analysis. In addition, detailed descriptions, scanned electron microscopy morphology, illustrations, and phylogenetic trees are provided to show the placement of these species.

Abstract
The diversity of Aspergillus species in clinical samples is continuously increasing. Species under the former name Eurotium, currently accommodated in section Aspergillus of the genus Aspergillus, are xerophilic fungi widely found in the human environment and able to grow on substrates with low water activity. However, their prevalence in the clinical setting is poorly known. We have studied the presence of these species in a set of clinical samples from the United States using a multilocus sequence analysis based on the internal transcribed spacer (ITS) region of the rRNA, and fragments of the genes β-tubulin (BenA), calmodulin (CaM), and polymerase II second largest subunit (RPB2). A total of 25 isolates were studied and identified as follows: A. montevidensis (44%), A. chevalieri (36%), A. pseudoglaucus (8%), and A. costiformis (4%). A new species Aspergillus microperforatus is also proposed, which represented 8% of the isolates studied and is characterized by uniseriate conidial heads, subglobose to pyriform vesicles, rough conidia, globose to subglobose cleistothecia, and lenticular and smooth ascospores. The in vitro antifungal activity of eight clinically available antifungals was also determined against these isolates, with the echinocandins and posaconazole having the most potent activity.

Abstract
We describe two novel fungi isolated from soil samples collected in Northern Argentina and belonging to the family Aspergillaceae of the order Eurotiales: Leiothecium cristatum sp. nov. and Aspergillus posadasensis sp. nov. Leiothecium cristatum sp. nov., represented by the ex-type strain FMR 11998(T) ( = CBS 134260(T) = NBRC 109843(T)), is distinguishable morphologically from the type species of the genus, Leiothecium ellipsoideum, by the presence of irregular reticulate ascospores with two prominent equatorial crests, and Aspergillus posadasensis sp. nov., represented by the ex-type strain FMR 12168(T) ( = CBS 134259(T) = NBRC 109845(T)), is differentiated from Aspergillus acanthosporus, the nearest species phylogenetically, by its non-sclerotioid ascomata and a lack of an asexual stage on all culture media tested. The taxonomic proposals are supported by the analysis of the sequences of the internal transcribed spacer region, the D1-D2 domains of the 28S rRNA gene, the fragments of the RNA polymerase II largest subunit, and the putative chaperonin complex related to TCP-1, β-tubulin and calmodulin genes.

Abstract
The genus Farrowia D. Hawksworth was established for members of the Chaetomiaceae with Botryotrichum-like anamorphs and long-necked ascomata, but the separation of Farrowia from Chaetomium Kunze has been questioned by mycologists who did not consider these characters to be significant at the generic level. The recent description of a species of Chaetomium with an aleurioconidial anamorph and long-necked ascomata prompted us to explore this question employing molecular characters. We sequenced a portion of the nuclear large ribosomal subunit rRNA gene (28S) of members of the Sordariales including species of Chaetomium, Farrowia and Thielavia. Phylogenetic analyses confirmed the monophyly of the Sordariales and the close relationship of Aporothielavia leptoderma to the genus Chaetomium. A sequence-based phylogeny identified a well-supported clade that included Chaetomium floriforme, Chaetomium sphaerale, members of the genus Farrowia, and longicollous species of Chaetomium with aleurioconidial anamorphs. A clade containing Chaetomium brevipilium, Chaetomium cuyabenoensis, Chaetomium homopilatum and species of Farrowia was inferred from the analysis of morphological characters, but this data set was found to be incongruent with the 28S sequence data. While these results are in agreement with the hypothesis that species of Farrowia comprise a group of closely related taxa, they do not provide strong support for the recognition of the genus Farrowia.Key words: anamorph, aleurioconidia, Botryotrichum, Chaetomium, 28S ribosomal RNA gene sequences.

Abstract
We studied the changes produced in Candida albicans yeast cells after treatment in vitro with sertaconazole, with light microscopy, transmission and scanning electron microscopy. Four different concentrations were evaluated (10(-6) M, 10(-5) M, 10(-4) M, 10(-3) M) and two times of action (12 and 17 h) for each concentration. This new antimycotic agent shows a considerable destructive effect in C. albicans cells. The alterations produced by sertaconazole were already manifested after 12 h at the concentration of 10(-6) M and a strong fungicidal activity recorded at 10(-4) M.
