Cordyceps sensu lato create tremendous economic value due to their medicinal,biological and nutritional importance.The objective of this study is classification of Cordyceps s.***.and optimization of large-scale production conditions for C.militaris and cordycepin.Furthrmore,this study helps in industrialization of C.militaris.More than 120 species of Cordyceps s.***.have been identified from China,Thailand and Russia based on morphology and multi-gene phylogenetic analyses.Among them,30 are new to the science.Cordyceps militaris has been used as a common mushroom in China and the market demand for artificial C.militaris has increased continuously.In the industrial application works,(1) Solid-state fermentation for fruiting-body and cordycepin production:the optimization strategies in solid medium culture lead to a fruit body yield increased 67.96%(about 1.73 g/bottle) and cordycepin yield in fruiting-body increased 55.36%(0.87%).Larger particle size of rice in the medium offers better fruit body growth,and the cordycepin production prefers smaller particle size.(2)Solid-state fermentation only for cordycepin production:medium components glucose,peptone,adenine and histidine have been examined.The levels of variables for CCD experiments were selected according to the above results of the One-factor-at-a-time method;maximum response of 18.92 mg/g cordycepin at levels of glucose26.25 g/L,peptone 26.25 g/L,adenine 7.50 g/L,and histidine 4.50 g/L as optimized medium components.This is the first report for improving the cordycepin production by using additives in this method.Isolates from colony sector mutation could be used for screening high-yield strains in cordycepin production and colony colour is one of the markers to detect fruit body and cordycepin production.(3) The separation and purification process of cordycepin:this optimization strategy leads to crystal of 60.45g with ratio of pure 98.05%,and the recovery rate is 43%.Our production line capacity is about 200kg/year.This study enriches the biodiversity of Cor

Fungi represent one of the most diverse groups of organisms on the planet,with an essential role in ecosystem processes and functioning.The numbers of fungi have always been an intriguing topic with several review papers being written on the subject.Perhaps the starting point was that of paper of D.L.Hawksworth in 1991 in which he estimated that there were roughly 1.5 million species.In the last ten years,new DNA sequencing technologies have revolutionized stud-ies of fungal taxonomy and diversity,leading to changes in the estimates of fungal species numbers ranging from 2.2 to 3.8 based on host association and 11.7 to 13.2 million species using high-throughput sequencing.

Species that has black ascomata with long necks, unitunicate, cylindrical asci with apical rings and fusiform, hyaline ascospores with or without mucilaginous sheaths are common in freshwater habitats in tropical and temperate areas（Shearer and Raja 2010）. Many of these taxa have originally been recorded as Annulatascaceae-like taxa. Twenty genera have been included in Annulatascaceae mostly by morphological characters, but molecular work and phylogenetic analyses are generally lacking（Maharachchikumbura et al.2016）. In this study, nine new Annulatascaceae-like taxa collected from Thailand were morphologically examined.Nine new strains and other known strains of Sordariomycetes species were used to establish a phylogenetic tree and evolution tree based on combined LSU, SSU, ITS and RPB2 sequence data. Phylogenetic analyses show that one new order Atractosporales and six new families are introduced to accommodate taxa excluded from Annulatascaceae sensu stricto. The new order Atractosporales includes three newly built families Conlariaceae,Pseudoproboscisporaceae and Atractosporaceae. Conlariaceae is introduced for genus Conlaria which comprises two species, Conlaria duplumascospora and a new coelomycetous asexual morph taxon Conlarium aquaticum which shows subglobose or irregular, brown, clathrate, muriform conidia. Pseudoproboscisporaceae includes Pseudoproboscispora and Diluviicola, while Atractosporaceae includes the genera Rubellisphaeria and Atractospora. Three genera Barbatosphaeria, Xylomelasma and Ceratostomella form a stable clade which is introduced as a new family Barbatosphaeriaceae in Diaportheomycetidae, families incertae sedis. A new family Lentomitellaceae is introduced in Diaportheomycetidae, families incertae sedis, to accommodate the genus Lentomitella. Woswasiaceae is introduced to accommodate Woswasia, Xylochrysis and Cyanoannulus in Diaportheomycetidae, families incertae sedis. Three new species of Fluminicola are introduced. A new sexual morph, Dictyosporella thailandensis, is reported and

A fungus similar to the monotypic genus Natarajania,isolated from dead wood and collected in Thailand,is reported.Analysis of partial ribosomal LSU and a protein coding gene(RPB2)demonstrated that the new isolate belonged to Stilbosporaceae,Diaporthales and genetically different from N.indica.It is unique in producing synnematous conidiophores,smooth-walled conidiogenous cells and a flared collarette but lacks an elongated collar-canal which is distinct in the type species.Therefore,sequence data and morphological traits are used to introduce the new species,Natarajania thailandica.

We isolated an interesting fungus from dead leaves of Magnolia liliifera collected from Chiang Mai,Thailand.The novel strain is related to Plectosphaer-ellaceae based on the morphology of its asexual morph and the analysis of sequence data.Phylogenetic analyses using a combined gene analysis of LSU and ITS sequence data showed that this strain is clustered in the same clade with Furcasterigmium furcatum with high statistical support.The new strains produced the asexual morph in culture which is morphologically similar to F.furcatum.Thus,we identified this strain as the sexual morph of F.furcatum.This is the first record of sexual morph for the monotypic genus Furcasterigmium and the first record of this genus on Magnolia.

Colletotrichum is an economically important pathogen with a worldwide distribution associated with a wide range of plant hosts.Characterization of the genomic profiles of Colletotrichum can generate new insights to understand its speciation,diversity,and pathogenicity potential.Although some genomic studies on this genus have been reported,a systematic comparative genomic analysis of the genus has so far been lacking.In this study,we first compared genome completeness generated by second-and third-generation sequencing platforms and confirmed the effectiveness of second-generation sequencing techniques for genomic studies.We then integrated the taxonomic concept of Colletotrichum species complexes into the comparative genomic analysis and depicted the genomic features of 102 Colletotrichum genomes from 39 species across ten species complexes and two singletons.Genome sizes of Colletotrichum species vary tremendously(44.15～109.66 Mb),and the average genome sizes of species complexes are significantly different.Repetitive sequences are the key drivers for genome size and GC content variation.The number of predicted genes of each genome(10,354～17,809) is positively correlated to the size of non-repeat genome sequences.Phylogenetically close strains consist of similar composition of secretomes,however,the number of major components is significantly different between different species complexes.The C.gloeosporioides species complex possessed the most abundant CAZymes,which may be responsible for its diverse distribution and higher pathogenicity.A total of 7,971 putative SMGCs covering 20 types were detected in these genomes,suggesting their immense biosynthetic potential to produce natural products.We further constructed a genome-scale TimeTree of Colletotrichum and investigated the evolution of gene families.The result suggested that gene gain and loss are both important for environmental adaption but less useful in delineating species complexes.Our study characterized the genomes of Colletotrichum species from diffe

Palms represent the most morphological diverse monocotyledonous plants and support a vast array of fungi. Recent examinations of palmicolous fungi in Thailand led to the discovery of a group of morphologically similar and interesting taxa. A polyphasic approach based on morphology, multi-gene phylogenetic analyses and divergence time estimates supports the establishment of a novel pleosporalean family Striatiguttulaceae, which diversified approximately 39（20–63） MYA（crown age） and 60（35–91） MYA（stem age）. Striatiguttulaceae is characterized by stromata or ascomata with a short to long neck, trabeculate pseudoparaphyses and fusiform to ellipsoidal, 1–3-septate ascospores, with longitudinal striations and paler end cells, surrounded by a mucilaginous sheath. Multi-gene phylogenetic analysis showed that taxa of Striatiguttulaceae form a well-supported and distinct monophyletic clade in Pleosporales, and related to Ligninsphaeriaceae and Pseudoastrosphaeriellaceae.However, these families can be morphologically demarcated by the slit-like ascomata and extremely large ascospores in Ligninsphaeriaceae and the rather narrow fusiform ascospores in Pseudoastrosphaeriellaceae.Eight strains of Striatiguttulaceae formed two monophyletic sub-clades, which can be recognized as Longicorpus gen. nov. and Striatiguttula gen. nov. Morphologically, the genus Longicorpus can be differentiated from Striatiguttula by its elongated immersed ascomata and fusiform ascospores with relatively larger middle cells and paler end cells. Two new species Striatiguttula nypae and S. phoenicis, and one new combination, Longicorpus striataspora are introduced with morphological details, and phylogenetic relationships are discussed based on DNA sequence data.

During our ongoing surveys of lignicolous freshwater fungi in the Greater Mekong Subregion, we encountered three interesting hyphomycetous fungi with similar characters, such as sporodochial colonies, short conidiophores, and subglobose, ellipsoidal to broadly obpyriform, aseptate, dark brown to black conidia. Based on morphological characters and phylogenetic analyses of combined LSU, ITS and RPB2 sequence data,Parafuscosporella bulbspora sp. nov., Conioscypha taiwaniana and Vanakripa minutiellipsoidea are identified. P.bulbspora clusters in Fuscosporellaceae, Fuscosporellales and is characterized by sporodochial colonies,cylindrical or globose to subglobose conidiogenous cells and bulb-shaped, dark brown to black conidia. C.taiwaniana and V. minutiellipsoidea clusters in Conioscyphales. Descriptions and illustrations of the new collections are provided. C. taiwaniana is a new record in Yunnan, China. This is the first report to show the phylogenetic placement of the genus Vanakripa.
