Chaetosphaeriaceae is one of the largest families in Sordariomycetes that commonly found on decaying leaf, fruit, branch, bark and wood in both terrestrial and submerged environment in nature. This paper reports our research result of diversity, taxonomy and phylogeny of anamorphic Chaetosphaeriaceae in China, which is based on a systematic study with an integrated approach of morphological observation and phylogenetic analysis for a large collection (>1300 herbarium specimens and 1177 living strains). The family Chaetosphaeriaceae is further expanded to accomendate 89 accepted genera, including 22 new genera and 10 newly assigned genera. Most of these genera (except for Chaetosphaeria and several other relatively large genera) are delimitated as monophyletic genera with well-defined diagnostic characters in morphology. The phylogenetic connection of non-phialidic Sporidesmium -like fungi with the family is further confirmed and expanded to 10 different genera. The polyphyletic Codinaea / Dictyochaeta/Tainosphaeria complex is further resolved with a taxonomic framework of 28 monophyletic genera by redelimitation of Codinaea and Dictyochaeta with narrow concept, acceptance of the 16 established genera, and finally introduction of 10 new genera. Chloridium is phylogenetically redefined as monophyletic genus with narrow concept as typified by the type species, a systematic review in both generic and species level is still needed. For biodiversity of chaetosphaeriaceous fungi, a total of 372 species in 76 genera, including 126 new species, 48 new combinations, and 1 new name, are documented. The identification keys are provided for most genera, especially the large genera such as Codinaea , Codinaeella , Stilbochaeta , Cryptophiale , Thozetella , Dinemasporium and Pseudolachnella . In addition, ten known species were excluded from the family and reclassified. One of the future research area for this family should be the systematic revision of several relatively large polyphyletic genera, including Bahusutrabeeja , Ellisembia , Stanjehughesia , Cacumisporium , Chaetosphaeria , Chloridium , Craspedodidymum , Cryptophiale, Cryptophialoidea , Dictyochaetopsis , Minimidochium , and many published species of Codinaea and Dictyochaeta .

In this contribution, 18 species of synnematous microfungi associated with plant debris are registered for the
first time to the Mexican mycobiota. In addition, an account of the current state of knowledge of the synnematous
species registered to date is presented. The taxonomic determination was carried out by morphological analysis of
the specimens growing in natural substrate incubated in damp chambers. Arthrobotryum stilboideum, Blastocatena
pulneyensis, Coremiella cubispora, Menisporopsis multisetula and Phaeoisaria clavulata are new records for the
Neotropical region. Blastocatena pulneyensis, Menisporopsis anisospora and Roigiella lignicola, which have not
been recorded since their original descriptions were also determined. Including the records of this study, a total of
40 species belonging to 28 genera of synnematous microfungi have been registered for Mexico. No information was
found for most of the states in the country. For the 18 species recorded in the present study, descriptions, illustrations
and information about their substrates and geographical distribution are provided. Reference material was deposited
in the Herbarium of the Instituto de Ecología A.C. (XAL) in Xalapa, Veracruz, Mexico.

several setulae at each end. The species is compared with other species having non-septate, setulate conidia and is described
as Dictyochaeta multifimbriata.
Freshwater fungi comprises a highly diverse group of organisms occurring in freshwater habitats throughout the world. During a survey of freshwater fungi on submerged wood in streams and lakes, a wide range of sexual and asexual species were collected mainly from karst regions in China and Thailand. Phylogenetic inferences using partial gene regions of LSU, ITS, SSU, TEF1α, and RPB2 sequences revealed that most of these fungi belonged to Dothideomycetes and Sordariomycetes and a few were related to Eurotiomycetes. Based on the morphology and multi-gene phylogeny, we introduce four new genera, viz. Aquabispora, Neocirrenalia, Ocellisimilis and Uvarisporella, and 47 new species, viz. Acrodictys chishuiensis, A. effusa, A. pyriformis, Actinocladium aquaticum, Annulatascus tratensis, Aquabispora setosa, Aqualignicola setosa, Aquimassariosphaeria vermiformis, Ceratosphaeria flava, Chaetosphaeria polygonalis, Conlarium muriforme, Digitodesmium chishuiense, Ellisembia aquirostrata, Fuscosporella atrobrunnea, Halobyssothecium aquifusiforme, H. caohaiense, Hongkongmyces aquisetosus, Kirschsteiniothelia dushanensis, Monilochaetes alsophilae, Mycoenterolobium macrosporum, Myrmecridium splendidum, Neohelicascus griseoflavus, Neohelicomyces denticulatus, Neohelicosporium fluviatile, Neokalmusia aquibrunnea, Neomassariosphaeria aquimucosa, Neomyrmecridium naviculare, Neospadicoides biseptata, Ocellisimilis clavata, Ophioceras thailandense, Paragaeumannomyces aquaticus, Phialoturbella aquilunata, Pleurohelicosporium hyalinum, Pseudodactylaria denticulata, P. longidenticulata, P. uniseptata, Pseudohalonectria aurantiaca, Rhamphoriopsis aquimicrospora, Setoseptoria bambusae, Shrungabeeja fluviatilis, Sporidesmium tratense, S. versicolor, Sporoschisma atroviride, Stanjehughesia aquatica, Thysanorea amniculi, Uvarisporella aquatica and Xylolentia aseptata, with an illustrated account, discussion of their taxonomic placement and comparison with morphological similar taxa. Seven new combinations are introduced, viz. Aquabispora grandispora (≡ Boerlagiomyces grandisporus), A. websteri (≡ Boerlagiomyces websteri), Ceratosphaeria suthepensis (≡ Pseudohalonectria suthepensis), Gamsomyces aquaticus (≡ Pseudobactrodesmium aquaticum), G. malabaricus (≡ Gangliostilbe malabarica), Neocirrenalia nigrospora (≡ Cirrenalia nigrospora), and Rhamphoriopsis glauca (≡ Chloridium glaucum). Ten new geographical records are reported in China and Thailand and nine species are first reported from freshwater habitats. Reference specimens are provided for Diplocladiella scalaroides and Neocirrenalia nigrospora (≡ Cirrenalia nigrospora). Systematic placement of the previously introduced genera Actinocladium, Aqualignicola, and Diplocladiella is first elucidated based on the reference specimens and new collections. Species recollected from China and Thailand are also described and illustrated. The overall trees of freshwater Dothideomycetes and Sordariomycetes collected in this study are provided respectively and genera or family/order trees are constructed for selected taxa.

Antecedentes y Objetivos:
Los micromicetos asexuales (MA) constituyen un grupo diverso y abundante de hongos en la naturaleza. Hasta la fecha para el Estado de México no se habían realizado estudios sobre estos hongos. El objetivo de esta aportación es proporcionar información sobre la riqueza taxonómica de las especies de MA que habitan en hojas vivas senescentes y muertas de cinco especies de Quercus de un bosque templado en el municipio Huixquilucan, Estado de México, México.
Métodos:
Durante un año, quincenalmente se cortaron hojas de cinco especies diferentes de encinos vivas senescentes y se recolectaron hojas del suelo. Las muestras se incubaron en cámaras húmedas; la revisión microscópica se efectuó dos veces por semana. La determinación taxonómica se basó en la conidiogénesis y en las características morfométricas de los conidiomas. El material de referencia (preparaciones microscópicas), se depositó en el herbario del Instituto de Ecología, A.C. (XAL) en Xalapa, Veracruz, México. Los nuevos registros para la micobiota de México se ilustran y describen en detalle.
Resultados clave:
Se identificaron 30 especies de MA, 12 de ellas constituyen nuevos registros para el país y todas lo son para el Estado de México. En las hojas muertas del suelo hubo un mayor número de especies que en las hojas vivas senescentes. Ocho de los taxones identificados no habían sido recolectados desde que fueron descritos como especies nuevas para la ciencia. Trichothecium roseum, Pestalotiopsis maculans y Vermiculariopsiella immersa son micromicetos que están ampliamente distribuidos en las hojas de todas las especies de encinos estudiadas.
Conclusiones:
La riqueza de MA encontrada en el área de estudio evidencia que las hojas de los Quercus son sustratos que albergan una considerable riqueza fúngica aun desconocida en México. Lo anterior es una importante razón para la conservación de los bosques de Quercus y promover estudios sobre este grupo de micromicetos en nuestro país.
Ceratosporium verrucosum and Diplocladiella alta are described as new species. Ceratosporium verrucosum was found on a dead bamboo culm and D. alta on rotting wood in Taiwan. Compared with the other species of Ceratosporium, C. verrucosum differs by the verrucose ornamentation covering the arms of the conidia. Diplocladiella alta is easily distinguished by the length of its conidiophores. For comparison with the previously described species of Ceratosporium, type material of C. fasciculare first was reexamined and Bactrodesmium submoniliforme recognized as the correct name for this species.
The original material of Trichaleurina polytricha and Urnula philippinarum housed in the Herbarium of the Swedish Museum of Natural History (S) was examined. The results of the morphological study prove they are synonyms of Trichaleurina javanica. The status of Sarcosoma javanicum and Bulgaria celebica are investigated, and a new species, Trichaleurina tenuispora, is proposed to replace one of the different interpretations of B. celebica. The anamorphic genus Kumanasamuha is discussed as well. Color pictures of dried and fresh specimens and microscopic characters are provided.
