Microascus brevicaulis
''Microascus brevicaulis'' is a microfungus in the Ascomycota,〔(【引用サイトリンク】url=http://www.mycobank.org/BioloMICS.aspx?Table=Mycobank&Rec=36461&Fields=All )〕 the largest and most diverse Phylum within the Kingdom Fungi.〔Kirk et al., p. 55.〕 Most of the discussion of this fungus in the scientific and medical literature has referred to the fungus using the name of its asexual form, or anamorph, ''Scopulariopsis brevicaulis''.〔Hawksworth, D. L. (2011). "A new dawn for the naming of fungi: impacts of decisions made in Melbourne in July 2011 on the future publication and regulation of fungal names". MycoKeys 1: 7–20. doi:10.3897/mycokeys.1.2062.〕 However, a sexual form (teleomorph) named ''Microascus brevicaulis'' was recently described. Under the current revision of ''International Code of Nomenclature for Algae, Fungi, and Plants'', as articulated in the (Melbourne Code ), it remains unclear which name this fungus will ultimately take.〔 Until further clarification, ''Microascus brevicaulis'' is considered the most recent, accepted name.〔 ''Microascus brevicaulis'' occurs world-wide as a saprotroph in soil, a common agent of biodeterioration, an irregular plant pathogen, and an occasional agent of human nail infection. Bartolomeo Gosio discovered in 1890 that under wet conditions ''M. brevicaulis'' produces significant amounts of trimethylarsine via biomethylation of inorganic pigments especially Paris green or Scheele's Green used in indoor wallpapers which is then released into the air.
==Morphology==
''Microascus brevicaulis'' is a common mold. When cultured at a temperature of 25 °C on potato dextrose agar it forms white colonies which become powdery and/or granular as they mature. Under such conditions the fungus can grow rapidly, expanding as much as 4.5 - 5.5 cm within one week. The hyphae of ''M. brevicaulis'' are hyaline (transparent) and septate (separated into segments by cross-walls). The anamorph has conidia that are flattened on the base and tapered at the apex, resembling a boat keel in cross-section or a pontifical mitre.〔 The conidia are produced in chains from cells known as annelides, phialide-like cells that elongate with each successive conidium produced.〔http://www.mycology.adelaide.edu.au/virtual/glossary/〕 These, in turn, range from solitary to arranged in complex broom-like clusters on fertile hyphae known as conidiophores.〔〔Fine Structure of Annellophores. I. Scopulariopsis brevicaulis and S. koningii Terrence M. Hammill American Journal of Botany Vol. 58, No. 1 (Jan., 1971), pp. 88-97〕 The fungus is a typical perithecial member of Phylum Ascomycota, producing minute, enclosed fruiting bodies containing sexual spores (ascospores) in sacs known as asci. The ascospores of ''M. brevicaulis'' are kidney-shaped and reddish-brown in colour.〔
