Fruit bodies of wild myxomycetes often have bright colors. In 1980 Steglich et al. isolated red and yellow pigments from methanol extracts of 2 g of the red fruit bodies of Arcyria denudata [7], Structure of these pigments were elucidated by spectral data as a series of bisindole maleimides, and they were named arcyriarubin B (1), C (2), arcyriaflavin B (3), C (4), and arcyrioxepin A (5). 1, 2, and 5 were red... 

Steglich et al. also studied the constituents of the fruit bodies of Lycogala epidendrum [17] and isolated not only lycogarubins A-C (31-33) but also lycogalic acid A (35) [18], staurosporinone (36) [19], and arcyriarubin A (6) and arcyriaflavin A (7) previously isolated from Arcyria denudata. 

Craterium, and there are also genuses which showed low germination ratio such as Cribraria and Arcyria. 

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).
