- Syncephalastrum racemosum
Hyphae broad, with no or few septa; Sporangiophores often branched, terminating in a vesicle; sporangia "finger-shaped" (merosporangia), formed around the vesicle; sporangiophores round, formed in a linear series in the interior of the merosporangia; rhizoids usually present.
|Surface:||Texture wooly; pale gray or dark gray in color on the surface.|
|Growth Rate:||Rapid to very rapid growth.|
Syncephalastrum is classified within the order Mucorales. It produces sporangiophores terminating in a vesicle upon the merosporangia are fixed. It is necessary to avoid confusing these structures with Aspergillus heads.
Syncephalastrum are primarily present in tropical or subtropical regions, where they are saprobes commonly isolated from animal dung and soil.
Normally considered nonpathogenic; no cases of infection have been reported in humans or animals. A common allergenic and contaminant.
