INTRODUCTION 
One of the authors (A.B.C.) has recently had the opportunity of exammmg 
marine algal specimens in European herbaria, and in so doing has noted the presence 
of a number of parasitic marine fungi, knowledge of which extends either the 
geographical or host range of three previously described species. 
The herbarium abbreviations used are as follows:-
LD, Botanical Museum and Herbarium, University of Lund, Sweden; 
L, Rijksherbarium, Leiden, Netherlands. 
Halogttignardia tumefaciens (Cribb & Herbert) A. B. & ]. W. Cribb 
A. B. & ]. W. Cribb 1956, p. 98. 
On Sargassum fallax Sond. Port Elliott, South Austraha, Miss Hussey 
(LD, H.erb. Agarclhiorum No. 2066). 
The galls are locafecl mainly on the tiner branches. Ascospores are, i� · general, 
a little smaller than in the type specimen, being mostly 35-40 f.L long, those of the 
type being 42-45.5 f.L· · However, in other respects the· specimens are in good 
agreement with the type. 
On Sargassum globularia�folium J. Ag. Coffs Harbour, New South Wales, 
H. Reick. (LD, Herb. Agardhiorum , No. 2095). 
Copious gall material occurs on leaf and stem, on the .latter sometimes more 
or less enveloping it for distances of up to 3 em. 
On Sargassum sinclairii Hook. & Harv. West Coast of New Zealand. (L, 
a specimen of Algae Muellerianae) . 
The gall on the short terete basal stipe of the plant contains spores in good 
agreement with those of the type specimen, except that they show a greater range 
of size and proportion, being mostly 30-50 X 14-18 f.L· 
On Sargassu,m dec1:piens (R Br. ex Tum.) ]. Ag. Pennington Bay, Kangaroo 
Island, South Australia, H.B.S. Womersley (KI. l864h) (L). 
The spores are mostly 50-56 X 1 0-21 f.L, being thus rather larger than those 
of the type specimen. However, the species appears to show considerable varicltion 
in spore size, and this South Australian specimen can probably be assigned to it.

Haloguignardia decidua A. B. & J. W. Cribb 
A. B. & J W. Cribb 1956, p. 97, pl. l, fig. l. 
On Sargassum daemelii Grunow. Rockhampton , Queensland, A. Daemel. (L) 
Two small galls were found, one on leaf and one on stem. Hyaline spore 
apic:es were not apparent , but this is not surprising since the apices in Haloguignardia 
decidua are very early deciduous. In spore size and shape and in pigmentation 
of the perithecia the specimen agrees well with the type specimen. 
MycojJhycophila gymnogongri (Feldmann) A. B. & J W. Cribb 
A. B. & J W. Cribb 1960, p. 43. 
On Gymnogongrus norvegicus (Gunn.) J. Ag. Atlantic Ocean. (L, No. 041, 
95 .... 360). 
On Galaxaura sp. Clarence Heads, New South Wales. (LD, Herb. Agardhiorum 
No. 32530). 
The brown-black, almost globose, perithecia to 360 /1. diam., arc embedded 
in the host with only the short black papillate ostiole reaching to the surface. The 
spores are similar to those of other Australian specimens of M ycophycophila but differ 
in their greater size, being mostly 22-28 X 7-11 /1.· while those of the other specimens 
we have seen are mostly 14-21 X 3.5-6 /1.· Further collections may show that 
taxonomic distinction is warranted for this plant, but spore size in some marine 
fungi is known to vary considerably, and at present it seems wiser to include the 
specimen under M. gymnogongri.
