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.

“…The genus Emericella has been reviewed several times, most recently by Horie et al (1996a), who recognized 32 species since then, three additional species have been described by Horie et al (1996bHorie et al ( , 1998 and Stchigel and Guarro (1997). Based on wall ornamentation of ascospores in scanning electron microscopic (SEM) work, these taxa fall into nine groups in the synoptic key, although the majority of the species are contained within the smooth group represented by E. nidulans (Eidam) Vuill (Fig.…”

Emericella qinqixianii, a new species isolated from desert soil from Sanchakou, Aksu, Qiemo, Yuli, Yutian, and the Taklimakan desert 100 km inland from Minfeng, Xinjiang Province, China, is described and illustrated. It is characterized by grayish yellow to olive brown, non-ostiolate ascomata surrounded by hyaline to pale yellowish brown h~ille cells, membranaceous peridium, prototunicate asci, and violet-brown, lenticular ascospores with two equatorial crests, smooth convex surfaces, and long filiform appendages. It has Aspergillus anamorph with biseriate aspergilla.

The correlation among molecular phylogenetics, morphological data, and growth temperature of the genus <i>Emericella</i>, and a new species

The species of the genus Emericella have been classified and identified on the basis of morphological features. However, the phylogenetic relationships in this genus have not been investigated. To clarify the relationships according to molecular phylogenetics, morphological characteristics, and growth temperature regimens in Emericella, multilocus sequencing analysis based on recent Aspergillus taxonomy was carried out. Various characteristic species formed individual clades, and maximum growth temperature reflected the phylogenetics. Emericella species exhibit various ascospore characteristics, although some species do not have distinct ascospore ornamentation. Species that have smooth-walled ascospores with two equatorial crests are polyphyletic. Here, Emericella pachycristata is described and illustrated as a new species. Its ascospores are similar to those of E. nidulans. These species produce smooth-walled ascospores, but the equatorial crests of E. pachycristata are thicker than those of E. nidulans. On the phylogenetic trees, E. pachycristata is closely related to E. rugulosa, which produces ascospores with ribbed convex surfaces. Thus, E. pachycristata is considered to be a new species both morphologically and phylogenetically.
