Varixanthone is an antimicrobial made by the marine fungus Emericella variecolor . [1]
The fungi imperfecti or imperfect fungi, are fungi which do not fit into the commonly established taxonomic classifications of fungi that are based on biological species concepts or morphological characteristics of sexual structures because their sexual form of reproduction has never been observed. They are known as imperfect fungi because only their asexual and vegetative phases are known. They have asexual form of reproduction, meaning that these fungi produce their spores asexually, in the process called sporogenesis.
Emericella discophora is a fungus. Its ascospores produce wide and entire, nonstellate equatorial crests. It was isolated from soil in Spain.
Emericella filifera is a fungus. Its ascospores form long appendages that emerge radially from narrow stellate crests. It was isolated from raisins in Argentina.
Emericella olivicola is a fungus. Its ascospores have star-shaped equatorial crests. It was isolated from olives in Italy.
Emericella stella-maris is a fungus. Its ascospores have star-shaped equatorial crests. It was isolated from leaf litter in Tunisia.
Emericella is a genus of fungi.
Isoemericellin is a bio-active isolate of the marine fungus Emericella variecolor.
Evariquinone is a chemical compound of the anthraquinone class which has been isolated from a sponge-derived strain of the fungus Emericella variecolor and from Aspergillus versicolor.
Aspergillus unguis is a species of fungus in the genus Aspergillus, and the asexual state (anamorph) of Emericella unguis. Aspergillus unguis is a filamentous soil-borne fungus found on decomposing plant matter and other moist substrates including with building materials and household dust. Aspergillus unguis occurs mainly in tropical and subtropical soils but has also been isolated from various marine and aquatic habitats. The species was first isolated in 1935 by Weill and L. Gaudin. Historically, A. unguis was assigned to the A. nidulans group, a common group of soil-borne fungi due to the resemblance of its ascospores and cleistothecia to those of Emericella nidulans. Aspergillus unguis is distinctive, however, in possessing spicular hyphae. A number of synonyms have been collapsed into this species, including Sterigmatocystis unguis, Aspergillus laokiashanensis and Aspergillus mellinus.
Aspergillus desertorum is a species of fungus in the genus Aspergillus which has been isolated from desert soil. It is from the Nidulantes section. Aspergillus desertorum produces desertorin A, desertorin B, desertorin C, paxiline and emindol DA.
Aspergillus olivicola is a species of fungus in the genus Aspergillus. It is from the Nidulantes section. The species was first described in 2008. It has been isolated from fruit in Italy. A. olivicola has been shown to produce aflatoxin B1, emericellin, shamixanthone, siderin, sterigmatocystin, terrein, and varitriol.
Aspergillus navahoensis is a species of fungus in the genus Aspergillus. It is from the Nidulantes section. The species was first described in 1982. It was isolated from sand in Arizona, United States. It has been reported to produce averufin, norsolorinic acid, 6,7,8-trihydroxy-3-methylisocoumarin, desferritriacetylfusigen, echinocandin B, and sterigmatocystin.
Aspergillus implicatus is a species of fungus in the genus Aspergillus. It is from the Sparsi section. The species was first described in 1994. It has been reported to produce a versicolorin derivative.

Aspergillus purpureus is a species of fungus in the genus Aspergillus. It is from the Nidulantes section. The species was first described in 1975. It has been isolated from soil in Egypt. It has been reported to produce emindol SA, emindol SB, emindol SC, epurpurin A-C, sterigmatocystin, variecolactone, variecolin, and variecolol.
Aspergillus sublatus is a species of fungus in the genus Aspergillus. It is from the Nidulantes section. The species was first described in 1979. It has been reported to produce asperthecin, nidulalin A, nidulalin B, and sterigmatocystin.
Guisinol is an antibacterial depside with the molecular formula C23H25ClO5 that has been isolated from the fungus Aspergillus unguis.
