“…A. nidulans is characterized by a “nestlike” fruiting body [ 36 ] and is known for producing xylanase [ 37 ]. A. montenegroi was first isolated from soil by Horie et al [ 38 ] (as Emericella montenegroi ). A. montenegroi is characterized by ascospores with reticulate and convex walls [ 38 ].…”

Aspergillus (Trichocomaceae, Eurotiales, and Ascomycota) is a genus of well-defined asexual spore-forming fungi that produce valuable compounds such as secondary metabolites and enzymes; however, some species are also responsible for diseases in plants and animals, including humans. To date, 26 Aspergillus species have been reported in Korea, with most species located in terrestrial environments. In our study, Aspergillus species were isolated from mudflats and sea sand along the western and southern coasts of Korea. A total of 84 strains were isolated and identified as 17 Aspergillus species in 11 sections on the basis of both morphological characteristics and sequence analysis of the calmodulin gene (CaM) locus. Commonly isolated species were A. fumigatus (26 strains), A. sydowii (14 strains), and A. terreus (10 strains). The diversity of Aspergillus species isolated from mudflats (13 species) was higher than the diversity of those from sea sand (five species). Four identified species—A. caesiellus, A. montenegroi, A. rhizopodus, and A. tabacinus—are in the first records in Korea. Here, we provide detailed descriptions of the morphological characteristics of these four species.

“…Aspergillus section Nidulantes accommodates Aspergillus nidulans and other species producing biseriate conidiophores with pale brown pigmented stipes, and if present, the ascomata embedded in masses of Hülle cells (Frisvad and Samson, 2004, Horie, 1978, Horie, 1979, Horie, 1980, Kong and Qi, 1986, Horie et al., 1989, Horie et al., 1990, Horie et al., 1996a, Horie et al., 1996b, Horie et al., 1998, Horie et al., 2000, Raper and Fennell, 1965, Samson and Mouchacca, 1975, Stchigel and Guarro, 1997, Thom and Raper, 1939, Zalar et al., 2008 and others). The majority of section Nidulantes species are able to produce a sexual state and those species were, in the dual name nomenclature system, assigned to the genus Emericella.…”

Aspergillus section Nidulantes includes species with striking morphological characters, such as biseriate conidiophores with brown-pigmented stipes, and if present, the production of ascomata embedded in masses of Hülle cells with often reddish brown ascospores. The majority of species in this section have a sexual state, which were named Emericella in the dual name nomenclature system. In the present study, strains belonging to subgenus Nidulantes were subjected to multilocus molecular phylogenetic analyses using internal transcribed spacer region (ITS), partial β-tubulin (BenA), calmodulin (CaM) and RNA polymerase II second largest subunit (RPB2) sequences. Nine sections are accepted in subgenus Nidulantes including the new section Cavernicolus. A polyphasic approach using morphological characters, extrolites, physiological characters and phylogeny was applied to investigate the taxonomy of section Nidulantes. Based on this approach, section Nidulantes is subdivided in seven clades and 65 species, and 10 species are described here as new. Morphological characters including colour, shape, size, and ornamentation of ascospores, shape and size of conidia and vesicles, growth temperatures are important for identifying species. Many species of section Nidulantes produce the carcinogenic mycotoxin sterigmatocystin. The most important mycotoxins in Aspergillus section Nidulantes are aflatoxins, sterigmatocystin, emestrin, fumitremorgins, asteltoxins, and paxillin while other extrolites are useful drugs or drug lead candidates such as echinocandins, mulundocandins, calbistrins, varitriols, variecolins and terrain. Aflatoxin B1 is produced by four species: A. astellatus, A. miraensis, A. olivicola, and A. venezuelensis.

Emericella appendiculata, a new species isolated from soil of the Pamire Plateau, is described and illustrated. It is characterized by grayish green non-ostiolate ascomata surrounded by a thick layer of h~ille cells, membranaceous peridiurn, prototunicate asci, violet-brown, lenticular ascospores which are ornamented by two stellate equatorial crests, capitate convex surfaces, and long filiform appendages, and an Aspergillus anamorph with biseriate conidiogenous cells.
