Abstract
The purpose of this study is to explore the genus Candolleomyces from Pakistan. Fungal surveys were conducted in different sites of the Punjab plains during the 2016-2022 period. Several specimens belonging to the family Psathyrellaceae were collected. Traditional morphology and multigene phylogenetic analyses confirmed the novelty and placement of the species in genus Candolleomyces. The phylogenetic study of the nuc rDNA internal transcribed spacer ITS1-5.8S-ITS2 (ITS) and partial 28S rRNA regions confirmed the distinct positions of four new taxa, Candolleomyces iqbalii, C. kotadduensis, C. pakistanicus, and C. parvipileus, in the genus. Currently, the genus consists of 43 species worldwide. However, with the inclusion of these four species, the total number has risen to 47. Detailed descriptions, phylogeny, comparisons, and illustrations are provided.

Abstract
Based on phylogenetic analysis, Candolleomyces (Psathyrellaceae, Agaricales) was established with Psathyrella candolleana as the type species. The basidiomes range from small to large and are typically terrestrial, lignicolous, and rarely fimicolous. We analysed the Candolleomyces species collected during five years in China, and based on morphological and molecular data (nrITS, nrLSU, and tef-1α), we propose seven new Candolleomyces species viz. C. brevisporus, C. gyirongicus, C. lignicola, C. luridus, C. shennongdingicus, C. shennongjianus, and C. sichuanicus. Full descriptions, colour photographs, illustrations, phylogenetic analyses results, and comparisons with related Candolleomyces species of the new taxa are provided. This study enriches the species diversity of Candolleomyces in China.

Enhancing Seed Germination of Cremastra appendiculata: Screening and Identification of Four New Symbiotic Fungi in the Psathyrellaceae Family. J Microbiol 2024:10.1007/s12275-024-00148-7. [PMID: 38940992 DOI: 10.1007/s12275-024-00148-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 05/05/2024] [Accepted: 05/09/2024] [Indexed: 06/29/2024]
Abstract
Several coprinoid fungi have been identified as promotors of Cremastra appendiculata seed germination, while others appear ineffective. This study aimed to discern which genera within the Psathyrellaceae family exhibit this capability and to identify the most effective coprinoid fungi for the cultivation of C. appendiculata. We collected 21 coprinoid fungi from diverse sources and symbiotically cultured them with C. appendiculata seeds. 9 fungi were found to induce seed germination and support seed development, specifically within the genera Coprinellus, Tulosesus, and Candolleomyces. In contrast, fungi that failed to promote germination predominantly belonged to the genera Coprinopsis and Parasola. Notably, four fungi-Coprinellus xanthothrix, Coprinellus pseudodisseminatus, Psathyrella singeri, and Psathyrella candolleana-were documented for the first time as capable of enhancing C. appendiculata seed germination. Strain 218LXJ-10, identified as Coprinellus radians, demonstrated the most significant effect and has been implemented in large-scale production, underscoring its considerable practical value. These findings contribute vital scientific insights for the conservation and sustainable use of C. appendiculata resources.

Abstract
Marine fungi have been studied for a long history in many realms, but there are few reports on marine mushrooms. In this study, marine fungi with conspicuous subglobose sequestrate basidioma were discovered from mangrove forests in South China. They grow on the deadwood of mangroves in the intertidal zone, periodically submerging into seawater due to the tide. Some marine animals were observed to nest in their basidiomata or consume them as food. The pileus-gleba-inner veil complex (PGI) of the basidioma was observed to be detached from the stipe and transferred into seawater by external forces, and drifting on sea to spread spores after maturity. The detachment mechanism of their PGIs was revealed through detailed microscopic observations. The contrast culturing experiment using freshwater and seawater potato dextrose agar media showed they have probably obligately adapted to the marine environment. Based on morphological and molecular phylogenetic evidence, two new species of Candolleomyces (Basidiomycota, Agaricales), namely C. brunneovagabundus and C. albovagabundus, were described. They are similar and close to each other, but can be distinguished by the size and color of the basidioma, and the size of the basidiospores.

Abstract
Many basidiomata of the genus Candolleomyces were found on sandy and loamy soil from the Indus Riverbed, Kot Addu District. A phylogenetic study was conducted to examine the occurrence of Candolleomyces sindhudeltae sp. nov. using a combination of ITS and LSU regions. Our morphological, anatomical, and phylogenetic studies indicated the novelty of Candolleomyces sindhudeltae sp. nov. The distinguishing features of C. sindhudeltae are convex to campanulate and areolate pileus with scalloped to cracked cap margins, branched, and pale reddish lamellae, greenish-brown ellipsoid to ovoid basidiospores, polymorphic cheilo, and caulocystidia. The novel taxa formed independent phylogenetic relationships within the genus Candolleomyces. The addition of our new species to the genus Candolleomyces makes us confident that the genus was separated from Psathyrella accurately.

Abstract
Although coprinoid mushrooms are widely known for the phenomenon of deliquescence and production of fungal laccases and extracellular peroxygenases, the genome structure and genetic diversity of coprinoid mushroom species have not been extensively studied. To reveal the genomic structure and diversity in coprinoid mushroom species, the genomes of five coprinoid mushroom species were compared and analyzed. A total of 24,303 orthologous gene families, including 89,462 genes, were identified in the five species. The numbers of core, softcore, dispensable, and private genes were 5617 (25.6%), 1628 (7.4%), 2083 (9.5%), and 12,574 (57.4%), respectively. Differentiation time analysis revealed that Coprinellus micaceus and Coprinellus angulatus differentiated approximately 181.0 million years ago. Coprinopsis cinerea and Coprinopsis marcescibilis differentiated approximately 131.0 million years ago, and they were differentiated from Candolleomyces aberdarensis approximately 176.0 million years ago. Gene family contraction and expansion analyses showed that 1465 genes and 532 gene families were expanded, and 95 genes and 134 gene families were contracted. Ninety-five laccase-coding genes were detected in the five species, and the distribution of the laccase-coding genes in the five species was not uniform. These data provide a reference for a deeper understanding of the genetic structure of the genomes of coprinoid mushroom species. Furthermore, this study provides a reference for follow-up studies on the genome structure of coprinoid mushroom species and the diversity of specific functional genes.

Abstract
In this work, we introduced a new report, Coprinopsis afrocinerea, a coprinoid mushroom from Pakistan. This species was collected several times during the monsoon season; it was found growing on animal dung and on sandy soil mixed with wood chips and leaf litter. This taxon was identified through morphological (macro- and micromorphology) techniques and molecular (ITS-region) markers. Results showed that Pakistani collection's macro- and micro-morphological characters match the type specimen of Coprinopsis afrocinerea. In the phylogenetic tree, sequences of our collections fall within section Cinereae and are clustered with type sequences of Coprinopsis afrocinerea with strong statistical support. This species has already been reported from Africa and is described here for the first time from Asia. Previously, only seven species of Coprinopsis have been reported from Pakistan, and in this study, the number of known taxa has increased to eight. This paper provides a detailed morphological and molecular analysis of this species to differentiate it from closely related taxa.

Rao G, Dai D, Zhao HN, Liang Y, Li Y, Zhang B. Two new psathyrelloid species of Coprinopsis (Agaricales, Psathyrellaceae) from China. MycoKeys 2021; 83:85-103. [PMID: 34594154 PMCID: PMC8443538 DOI: 10.3897/mycokeys.83.71405] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Accepted: 08/20/2021] [Indexed: 01/04/2023] Open
Abstract
In this study, Coprinopsisjilinensis and Coprinopsispusilla were introduced, based on their morphological characteristics, the internal transcribed spacer (ITS) and large subunit ribosomal (LSU) region sequences of nrDNA. These new psathyrelloid species were found in Jilin Province, China. Coprinopsisjilinensis has brown pileus, utriform pleurocystidia, brown, smooth, dextrinoid basidiospores and tiny pore. It mainly grows on humus. Coprinopsispusilla has small basidiomata, greyish-white pileus, thick and distinct veil at edges, subcolourless and verrucose basidiospores. It is poreless and it grows on the decaying wood of broad-leaved trees. Both of them belong to the C.sect.Melanthinae. A supplementary description of C.sect.Melanthinae was given in combination with the newly-discovered taxa and an identification key to the fourteen psathyrelloid species of Coprinopsis is provided. Coprinopsissect.Canocipes and C.sect.Quartoconatae were evaluated and the phylogenetic position of the psathyrelloid species of Coprinopsis was discussed. Psathyrellasubagraria, as a confusing species, was also discussed in this study.

The functional expression in yeast of two unusual acidic peroxygenases from Candolleomyces aberdarensis by adopting evolved secretion mutations. Appl Environ Microbiol 2021; 87:e0087821. [PMID: 34288703 DOI: 10.1128/aem.00878-21] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
Fungal unspecific peroxygenases (UPOs) are emergent biocatalysts that perform highly selective C-H oxyfunctionalizations of organic compounds, yet their heterologous production at high levels is required for their practical use in synthetic chemistry. Here, we achieved functional expression in yeast of two new unusual acidic peroxygenases from Candolleomyces (Psathyrella) aberdarensis (PabUPO) and their production at large scale in bioreactor. Our strategy was based on adopting secretion mutations from Agrocybe aegerita UPO mutant -PaDa-I variant- designed by directed evolution for functional expression in yeast, which belongs to the same phylogenetic family as PabUPOs -long-type UPOs- and that shares 65% sequence identity. After replacing the native signal peptides by the evolved leader sequence from PaDa-I, we constructed and screened site-directed recombination mutant libraries yielding two recombinant PabUPOs with expression levels of 5.4 and 14.1 mg/L in S. cerevisiae. These variants were subsequently transferred to P. pastoris for overproduction in fed-batch bioreactor, boosting expression levels up to 290 mg/L with the highest volumetric activity achieved to date for a recombinant peroxygenase (60,000 U/L, with veratryl alcohol as substrate). With a broad pH activity profile, ranging from 2.0 to 9.0, these highly secreted, active and stable peroxygenases are promising tools for future engineering endeavors, as well as for their direct application in different industrial and environmental settings. IMPORTANCE In this work, we incorporated several secretion mutations from an evolved fungal peroxygenase to enhance the production of active and stable forms of two unusual acidic peroxygenases. The tandem-yeast expression system based on S. cerevisiae for directed evolution and P. pastoris for overproduction in a ∼300 mg/L scale, is a versatile tool to generate UPO variants. By employing this approach, we foresee that acidic UPO variants will be more readily engineered in the near future and adapted to practical enzyme cascade reactions that can be performed over a broad pH range to oxyfunctionalize a variety of organic compounds.

Bau T, Yan JQ. Two new rare species of Candolleomyces with pale spores from China. MycoKeys 2021; 80:149-161. [PMID: 34163303 PMCID: PMC8192403 DOI: 10.3897/mycokeys.80.67166] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Accepted: 05/23/2021] [Indexed: 11/12/2022] Open
Abstract
Most species of Candolleomyces have brown or dark brown spores. Although pale-spored members are rare in the genus we frequently collected two such species from many Provinces during our investigations in subtropical China from 2016-2020. As revealed by morphological characterisation and multigene phylogenetic analyses (ITS LSU β-tub and tef-1α) these species which we have named C. subcacao and C. subminutisporus are unique and distinct from known taxa. In addition a new combination C. cladii-marisci is proposed on the basis of ITS sequence analysis of the type specimen. Detailed descriptions colour photos illustrations and a key to related species are presented.
