Summary
The new species Streptosporangium longisporum is described. It differs mainly from the other members of the genus by the shape of the sporangiospores which are cylindrical to oblong or allantoid; the average size is 0.7×2.1 μ, usually they are three times longer than wide. On most of the media the colour of the colonies is bright red, occasionally±brownish red. When bearing mature sporangia the aerial mycelium is pink. Melanin or other soluble pigments are not produced.
In a comparative study of Streptosporangium indianesis no true sporangia were observed. Therefore the species should be excluded from the genus.
Zusammenfassung
Die neue Art Streptosporangium longisporum wird beschrieben. Morphologisch weicht sie insbesondere durch stäbchenförmige Sporangiosporen von allen anderen Arten der Gattung ab. Im Unterschied zu den übrigen Streptosporangium-Arten sind die Kolonien oft leuchtend rot, seltener bräunlich rot gefärbt. Die Farbe des Luftmycels mit reifen Sporangien ist rosa. Melanin oder sonstige Pigmente im Medium werden nicht produziert.
Vergleichende Untersuchungen an den beschriebenen Streptosporangium-Arten machen es wahrscheinlich, daß Streptosporangium indianesis nicht zu dieser Gattung gehört.
