Fuligo

Dihydroarcyriarubin C (104), a new bisindole alkaloid, has been isolated from fruit bodies of a myxomycete Arcyria ferruginea, which was collected at Hao, Yasu-cho, Kochi Prefecture, together with two known bisindoles, arcyriarubin C (2) and arcyriaflavin C (4), and the structure of 104 was elucidated by spectral data. Arcyriaflavin C (4) was also obtained, together with arcyriaflavin B (3), from fruit bodies of Tub if era casparyi, which ( 16839) was collected at Mt. Miune, Monobe-mura, Kochi Prefecture, in November 1997. Arcyriaflavin C (4) was revealed to exhibit cell cycle inhibition activity on HeLa cells on the basis of flow cytometry studies. Fruit bodies of Fuligo Candida, which ( 23446) was collected at Motoyama-cho, Kochi Prefecture, in August 2002, were revealed to contain a relatively high quantity of cycloanthranilylproline (105). 

BATTITURA AERIS — is Metallic Slag in Greek, Lepidos in Arabic, Cubel, or Tubel, or Fuligo (smoke, soot) in German, Haneerschlag. 

FULIGO — Painter s Black, Cream-soot, is made in several ways and of many materials among us, out of pitch. Dioscorides says that it is obtained from glassblowers. Its medical virtue is astringent and consuming. 

FULIGO METALLORUM — Properly Arsenic, but it often signifies Mercury. 

Scheme 18.2 Fuligorubin A, a polyene acyltetramic acid pigment isolated from the yellow slime mold Fuligo septica (L).

C20H23NO5, Mr 357.41, red crystals, mp. 150 °C (dihydrate), an optically active tetramic acid derivative from the yellow plasmodia of the slime mold Fuligo septica (Myxomycetes). F. exists in Fuligo as a stable calcium complex. F. is assumed to possess photoreceptor properties and to play a role in the phototaxis and sporulation of the slime mold.

Recent digital 3D microscopy should also be added here. It enables useful surveys to be carried out on composite materials for locating sites of interest, which can then be studied with AFM and SNOM. A brief description is given in Ref. 3. The available enlargement is up to 5000-fold to the screen. For example, the nuclei of Fuligo varians are observed with a diameter of 3 mm (0.6 J,m) to 10 mm (2.0 jm). Combined use of 3D microscopy with nanoscopic techniques has appeared. " ... 

The fruiting body (yellow) of the slime mold Fuligo septica appears on a patch of leaves. 

Heaton (1928) simply calls bistre bituminous charcoal . Other historical terms include caligo,fuligino and fuligo (for example, Merrifield (1849), who also lists one of the meanings of atra-mentum as being related).
