Apophysomyces : ウィキペディア英語版 | Apophysomyces
''Apophysomyces'' is a genus of filamentous fungi that are commonly found in soil and decaying vegetation. Species normally grow in tropical to subtropical regions.〔L. Collier, A. Balows, and M. Sussman, "Topley & Wilson's Microbiology and Microbial Infections", 9th ed. (1998), vol. 4. (London, Sydney, Auckland, New York). ISBN 0-340-80912-4 (ISBN is for 10th ed.)〕 The genus ''Apophysomyces'' historically was monospecific, containing only the type species ''Apophysomyces elegans''. In 2010, three new species were described: ''A. variabilis'', ''A. trapeziformis'', and ''A. ossiformis''. ==Characteristics== Among the other members of zygomycetes, ''Apophysomyces elegans'' mostly resembles those from genus ''Absidia''. However, its bell-shaped (although not conical) apophyses (outgrowth), the existence of its foot-cell like hyphal segment, rhizoids produced opposite to the sporangiophores upon cultivation on plain agar, the darker and thicker subapical segment, and inability to sporulate on routine culture media help in distinguishing ''Apophysomyces elegans''.〔Davise H. Larone, "Medically Important Fungi - A Guide to Identification", 3rd ed. (1995). (ASM Press, Washington, D.C.). ISBN 1-55581-172-8 (ISBN is for 4th ed.)〕 ''Apophysomyces elegans'' is a thermotolerant fungus: it has been found to grow favourably at temperatures of 26°C and 37°C, and it grows rapidly at 42°C. Its colonies are fluffy and cottony in appearance. The surface of the colony is white initially and turns to a brownish-grey or yellowish-cream as the culture ages, while the underside is white to pale yellow in colour.〔〔L. Collier, A. Balows, and M. Sussman, "Topley & Wilson's Microbiology and Microbial Infections", 9th ed. (1998), vol. 4, p. 463. (London, Sydney, Auckland, New York). ISBN 0-340-80912-4 (ISBN is for 10th ed.)〕
