|Abstract:||Gracilaria mixta from South China is one of several terete species
of Gracllaria that requires critical microscopic examination for identification.
This new species demonstrates a mixture of spermatangial types that recently
have been used to separate genera in the Gracilariaceae: the simple, pitlike
Verrucosa type and the multicavitied Polycavernosa type arrangements. The first
type is seen in the youngest branch portions, gradually changing to the second
type in older parts. Both types of arrangements occasionally may be seen in the
same cross section. Reexamination of male plants of the western Pacific taxa
placed in Polycavernosa (= Hydropuntia) also shows both types of configurations
in the same thalli. However, some species of Gracilaria with Verrucosa-type
spermatangia maintain that type throughout the plants. These observations
require a transfer of names from Hydropuntia (= Polycavernosa) to Gracilaria.
From 16 taxa, 4 are retained in Gracilaria, 2 receive new names because of earlier
homonyms, and 10 become new combinations within Gracilaria.
