Sexual reproduction is the basic way to form high genetic diversity and it is beneficial in evolution and speciation of fungi. The global diversity of teleomorphic species in Ascomycota has not been estimated. This paper estimates the species number for sexual ascomycetes based on five different estimation approaches, viz. by numbers of described fungi, by fungus:substrate ratio, by ecological distribution, by meta-DNA barcoding or culture-independent studies and by previous estimates of species in Ascomycota. The assumptions were made with the currently most accepted, “2.2–3.8 million” species estimate and results of previous studies concluding that 90% of the described ascomycetes reproduce sexually. The Catalogue of Life, Species Fungorum and published research were used for data procurement. The average value of teleomorphic species in Ascomycota from all methods is 1.86 million, ranging from 1.37 to 2.56 million. However, only around 83,000 teleomorphic species have been described in Ascomycota and deposited in data repositories. The ratio between described teleomorphic ascomycetes to predicted teleomorphic ascomycetes is 1:22. Therefore, where are the undiscovered teleomorphic ascomycetes? The undescribed species are no doubt to be found in biodiversity hot spots, poorly-studied areas and species complexes. Other poorly studied niches include extremophiles, lichenicolous fungi, human pathogens, marine fungi, and fungicolous fungi. Undescribed species are present in unexamined collections in specimen repositories or incompletely described earlier species. Nomenclatural issues, such as the use of separate names for teleomorph and anamorphs, synonyms, conspecific names, illegitimate and invalid names also affect the number of described species. Interspecies introgression results in new species, while species numbers are reduced by extinctions.

Our studies on lignicolous aquatic fungi in Thailand, Sweden, and the UK resulted in the collection of three new Halobyssothecium species (H. bambusicola, H. phragmitis, H. versicolor) assigned to Lentitheciaceae (Pleosporales, Dothideomycetes). Multi-loci phylogenetic analyses of the combined large subunit, small subunit, internal transcribed spacers of ribosomal DNA, and the translation elongation factor 1-alpha sequence data enabled a revision of the taxa assigned to Lentithecium and the transfer of L. cangshanense, L. carbonneanum, L. kunmingense, L. unicellulare, and L. voraginesporum to Halobyssothecium. Collection of an asexual morph of L. lineare and phylogenetic analysis confirmed its taxonomic placement in Keissleriella. Detailed descriptions and illustrations of H. bambusicola, H. phragmitis, and H. versicolor are provided.

An investigation of freshwater fungi in Thailand resulted in the collection of one new monotypic genus, Neoxylomyces, and a novel species each in Camposporium, Brunneofusispora, Rattania, Neoxylomyces, and Phaeoacremonium.Camposporium dulciaquae resembles C. septatum in conidial morphology and number of septa but differs in conidial sizes. Brunneofusispora hyalina is similar to B. sinensis in conidiogenesis and conidial shape but differs in the sizes of conidiomata and conidiogenous cells. Rattania aquatica is the second species in Rattania, while Phaeoacremonium thailandense is the third species recorded from freshwater habitats. A new genus, Neoxylomyces, typified by N. multiseptatus, is similar to Xylomyces giganteus, but differs in the number of septa, chlamydospore measurements, and absence of a mucilaginous coating around the chlamydospores. These novel taxa form an independent lineage distinct from other species based on multi-loci phylogenetic analyses. Descriptions, illustrations, and notes are provided for each taxon. These new freshwater ascomycetes add to the increasing number of fungi known from Thailand and it is now evident that there are numerous novel taxa awaiting to be described as new freshwater habitats are explored. An update of newly discovered taxa in the widely studied freshwater habitats of Thailand over the last five years is also provided.
