CONFIRMED RECORD: -- GERMANY: Minden (loc. cit.).
EXCLUDED TAXA
Saprolegnia androgyna Archer
Quart. J. Microscop. Sci. (N. S.) 7:123, pl. 6, fig. 1. 1867
Humphrey (1893) assigned this species to Aplanes, but it is doubtless an Achlya,
and is so treated here.
Saprolegnia bernardensis Harvey
J. Elisha Mitchell Sci. Soc. 58:22, pl. 3. 1942
This is an illegitimate name, having been published without an accompanying
Latin diagnosis. The specimens as described by Harvey were probably only forms of
Saprolegnia ferax. Upadhay (1967) reported finding this species in Brazil.
Saprolegnia candida Kützing
Species Algarum, p. 159. 1849
The filaments (hyphae) were described as having obtuse apices. Kützing (loc.
cit.) placed Agardh’s (1824) Leptomitus candidus into synonymy with Saprolegnia candida,
but from Agardh’s description, it would appear likely that he was indeed describing a
Leptomitus. This being the case, and assuming that Kützing was correct in his decision,
S. candida was probably a Leptomitus.
Saprolegnia capitulifera Braun
Betrachtungen über die Erscheinung der Verjüngung in der Natur..., p. 20l. 1851
The fungus described by A. Braun (loc. cit.; 1853) was doubtless an Achlya, but in
writing of the “fruit clubs” (sporangia), he stated that they were imperfect because new
ones did not grow through the emptied ones as in Saprolegnia ferax. Clearly, Braun saw
spore formation and discharge, and oogonium and oospore development, but was
unaware of the significance of the latter. There is insufficient information in his account
to identify this Achlya with certainty. Schröter’s (1889) contention that Braun’s species
was Achlya prolifera is not supported by direct evidence.
Saprolegnia corcagiensis Hartog
Quart. J. Microscop. Sci. (N. S.) 27:429 f. 1886-87
It is likely that Hartog was dealing with a mixed culture, since the sporangia of
this species as he described them were of a leptomitaceous fungus, and the oogonia of
652
