PUBLICATION REFERENCE Dörfelt H, Schäfer U. 1998. Fossil fungi in amber of the alpic Trias; Zeitschrift für Mykologie, v. 64, p. 141-151.
K&J REMARKS The short branches arising from the vesicles, forming loops clasping the main hyphae, may be comparable to the extended hyphal tubes arising from the oogonium on germination, or to the elongated antheridial tubes clasping or adhering to the oogonium, as occur in association with the oogonia of modern Saprolegnia. This was the tentative conclusion reached by Poinar et al. (1993), after they studied a possible algal or fungal vesicular structure (loc. cit., fig. 1L) from the Triassic amber of southern Germany, which they compared to an oogonium with oospheres of an extant Saprolegnia.

The microcenosis in which this fossil occurs was discussed further by Schönborn et al. 1999 (quo vide).
