... Subsequently, researchers started using protein-coding genes (e.g., TEF1, BenA, CaM, TUB, etc.) for fungal identification under the phylogenetic species concepts. However, standardization was lacking [73][74][75], and no cutoff scores for fungal species identification were available [76]. Furthermore, ANI analysis is not regularly used for the identification of fungi as practiced for bacterial species because fungal genomes are complex and their WGS are scarce in public databases [77]. ...
National Aeronautics and Space Administration’s (NASA) spacecraft assembly facilities
are monitored for the presence of any bacteria or fungi that might conceivably survive a transfer to an extraterrestrial environment. Fungi present a broad and diverse range of phenotypic and functional traits to adapt to extreme conditions, hence the detection of fungi and subsequent eradication of them are needed to prevent forward contamination for future NASA missions. During the construction and assembly for the Mars 2020 mission, three fungal strains with unique morphological and phylogenetic
properties were isolated from spacecraft assembly facilities. The reconstruction of phylogenetic trees based on several gene loci (ITS, LSU, SSU, RPB, TUB, TEF1) using multi-locus sequence typing (MLST) and whole genome sequencing (WGS) analyses supported the hypothesis that these were novel species. Here we report the genus or species-level classification of these three novel strains via a polyphasic approach using phylogenetic analysis, colony and cell morphology, and comparative anal-
ysis of WGS. The strain FJI-L9-BK-P1 isolated from the Jet Propulsion Laboratory Spacecraft Assembly Facility (JPL-SAF) exhibited a putative phylogenetic relationship with the strain Aaosphaeria arxii CBS175.79 but showed distinct morphology and microscopic features. Another JPL-SAF strain, FJII-L3-CM-DR1, was phylogenetically distinct from members of the family Trichomeriaceae and exhibited morphologically different features from the genera Lithohypha and Strelitziana. The strain FKI-L1-BK-
DR1 isolated from the Kennedy Space Center facility was identified as a member of Dothideomycetes incertae sedis and is closely related to the family Kirschsteiniotheliaceae according to a phylogenetic analysis. The polyphasic taxonomic approach supported the recommendation for establishing two novel genera and one novel species. The names Aaosphaeria pasadenensis (FJI-L9-BK-P1 = NRRL 64424 = DSM 114621), Pasadenomyces melaninifex (FJII-L3-CM-DR1 = NRRL 64433 = DSM 114623), and Floridaphiala radiotolerans (FKI-L1-BK-DR1 = NRRL 64434 = DSM 114624) are proposed as type species. Furthermore, resistance to ultraviolet-C and presence of specific biosynthetic gene cluster(s) coding for metabolically active compounds are unique to these strains.

This paper highlights the taxonomy of some interesting saprobic microfungi associated with dead plant materials of Hedychium coronarium, Lilium longiflorum, and Magnolia species. The taxa reported in this study belong to the orders Pleosporales and Kirschsteiniotheliales (Dothideomycetes). These taxa were identified based on multi-locus phylogeny of nuclear ribosomal DNA (rDNA) (LSU, SSU, and ITS) and protein-coding genes (tef1-α and rpb2), together with comprehensive morphological characterization. Two novel saprobic species, Leptoparies magnoliae sp. nov. and Neobambusicola magnoliae sp. nov., are introduced from Magnolia species in Thailand. Another new species, Asymmetrispora zingiberacearum sp. nov., is also described from dead stems of H. coronarium, which is the first asexual morph species of the genus Asymmetrispora. In addition, Ramusculicola thailandica and Kirschsteiniothelia thailandica are reported as new host records from dead twigs of Magnolia species. Sphaerellopsis paraphysata is reported as a new host record from L. longiflorum. Newly described taxa are compared with other similar species and detailed descriptions, micrographs, and phylogenetic trees to show the positions are provided.

Pyrenochaeta fraxinina was first described in 1913 from the state of New York (USA) on petioles of Fraxinus sp. Since then, the species has not been reported from North America and reports from the other regions of the world are very sparse. The results of this study on P . fraxinina are based on the material collected in various regions of Poland from 2012 to 2019. The material comprised 2700 previous year’s leaf petioles of Fraxinus excelsior and 1970 petioles or leaf residues of eight other deciduous tree species. As a result, the occurrence of pycnidial conidiomata of P . fraxinina was confirmed on F . excelsior (3.4% of petioles), F . mandshurica (1.5%), F . pennsylvanica (3.2%), and Acer pseudoplatanus (2.0%). The morphology of the microstructures was described based on the fresh material and compared with the holotype of P . fraxinina . The optimal temperature for the growth of the fungus in vitro was estimated as 20 °C. The analyses based on ITS-LSU rDNA sequences and a protein coding sequence of TUB2 and RPB2 genes showed that P . fraxinina isolates form a well-supported clade in the phylogenetic trees. The species proved to be closely related to Nematostoma parasiticum (asexual morph Pyrenochaeta parasitica ), a species occurring on Abies alba in connection with needle browning disease. Interactions between P . fraxinina and the ash dieback pathogen, Hymenoscyphus fraxineus , were analyzed in vivo on ash petioles and in vitro in dual cultures. Among 93 petioles of F . excelsior , for which P . fraxinina conidiomata were detected, 26 were also colonized by H . fraxineus . Mostly, these two fungi occurred separately, colonizing different sections of a petiole. For all dual cultures, both fungi, P . fraxinina and H . fraxineus , showed growth inhibition toward the counterpartner. The role of P . fraxinina as a saprotrophic competitor toward H . fraxineus in ash petioles is discussed.
... Herpotrichia xiaokongense is distinct from extant species in Melanommataceae and formed a sister clade to H. macrotricha with 100% ML, 1.00 PP bootstrap support (Fig. 10). Herpotrichia xiaokongense is similar to H. macrotricha in having broad cap-like ascomatal apex with a thick inner layer of hyaline pseudoparenchymatous cells (Mugambi & Huhndorf 2009). However, Herpotrichia xiaokongense differs from H. macrotricha in having 1septate, hyaline ascospores with an expanded gelatinous sheath, while H. macrotricha has 1-(3-5)septate, hyaline to brown ascospores with narrow sheath often elongate over tips (Barr 1984, Chen & Hsieh 2004, Tanaka & Hosoya 2006. ...

Even though the putative strains of Decaisnella formosa (BCC 25616, BCC 25617) and Thyridaria macrostomoides (GKM 1033, GKM 1159, GKM 224N) are phylogenetically affiliated in Phaeoseptaceae [37,47], they are not related to any type specimens. Therefore, it is necessary to recollect and epitypify them with DNA sequence data in order to ensure correct generic placement of these two species [49,50]. ...
In the course of investigating the systematics of woody litter micromycete associates in Yunnan Province, China, we found one new species in Phaeoseptaceae, one new genus and three new species in Sulcatisporaceae from 16 specimens collected (ten collections of ascomycetous teleomorphs, four collections of hyphomycetous and two collections of coelomycetes anamorphs) from Ailaoshan, Chuxiong, Diqing, Honghe, Kunming, Lancang, Mengla and Yuxi in Yunnan Province. These taxonomic novelties were recognized with the aid of morphological comparisons and phylogenetic analyses of multiple gene sequences (non-translated loci and protein-coding regions). Pleopunctum menglaense sp. nov. is accommodated in Phaeoseptaceae (Pleosporales) based on its hyphomycetous anamorph, which is characterized by superficial sporodochia on the host surface, macronematous, mononematous, cylindrical, unbranched, aseptate, hyaline and smooth-walled conidiophores, monoblastic, terminal, hyaline conidiogenous cells, hyaline, muriform α conidia, and brown, muriform β conidia with tri-lobed wing like basal cells. Kazuakitanaka gen. nov. (type: K. yuxiensis) is introduced in Sulcatisporaceae (Massarineae, Pleosporales) for a saprobic ascomycete with teleomorphic and anamorphic (coelomycetous) features. The teleomorph possesses globose to subglobose ascomata with acentric ostiole, a peridial wall of textura angularis to textura prismatica, cylindric-clavate, pedicellate asci with an ocular chamber, and 1–2-septate, hyaline, fusiform, guttulate ascospores with a distinct mucilaginous sheath. The anamorph features pycnidial conidiomata, phialidic, ampulliform to cylindrical, hyaline conidiogenous cells and ampulliform to cylindrical, one-to-three-septate, hyaline, guttulate conidia. Loculosulcatispora was known only from its anamorph of L. thailandica. We observed the teleomorph of Loculosulcatispora hongheensis sp. nov. and amended the generic description of Loculosulcatispora accordingly. Loculosulcatispora hongheensis is characterized by globose to subglobose ascomata with a central ostiole, a peridial wall of textura angularis to globosa, branched, septate, pseudoparaphyses, clavate asci with a short pedicel and a minute ocular chamber and hyaline, fusiform, 1-septate ascospores with a thick irregular mucilaginous sheath. This study provides some insights into the diversity of fungi on dead woody litter in terrestrial habitats.

The types of damage to Cupressaceae and Pinaceae conifers from the Arkhara-Boguchan, Belaya Gora, and Progress localities (Amur Region, Russia; Paleocene) are analyzed. Most of the damage types were caused by various microscopic fungi of the Ascomycota. Fungal remains are represented by hyphae, chains of conidia, different fruiting bodies, and dispersed spores of three types. The problem of differentiation of morphologically similar damage caused by arthropods and micromycetes is discussed. The abundance of diverse micromycetes on various organs of Paleocene conifers is consistent with previously obtained data on the existence of these plants in a temperate humid climate with a hot summer and without a dry season.
