SOME AUSTRALIAN FUNGI. 
Ascochyta apiospora, Cke. Sf Mass. 
Maculis epiphyllis, orbiculari-difformibus, fuscis, zona purpurea 
cinctis ; peritheciis minutis, innatis, ostiolo parvulo pertusis, 
sporulis pvriformibus, inaequaliter didymis, bvalino-fuscis, loculo 
superiori subgloboso, amplo, loculo inferiori minuto, papillaeformi, 
12 x 12 p. 
On leaves of myrtle. Johnstone River. (Bailey, 499.) 
Ascochyta biunnea, CJce. Mass. 
Maculis amphigenis, orbiculari-difformibus, pallide fuscis, 
ocbraceisve, linea obscuriori elevato cinctis ; peritheciis minutis, 
punctiformibus, atris, innatis, demum emergentibus. Sporulis arcte 
ellipticis, uniseptatis, hyalinis (12 x 4 yu) basidiis aequalibus. 
On leaflets of tree unknown (Sapindacece ?) . Brisbane. (Bailey, 
506.) 
Erysiphe vitigera, Cke. fy Mass. 
Hypophylla, mycelio floccoso, persistente, peritheciis gregariis, 
minutissimis (4 mm. diam.), sphaeroideis ; appendicibus obsoletis 
vel cum mycelio intertextis, ascis pvriformibus (4 in singulo peri- 
thecio), 50 x 30 /x, bisporis. Sporidiis ellipticis, hyalinis, 18x9 /x. 
On leaves of grape vine. Near Melbourne. (Mueller.) 
Allied to E. lamprocarpa , but apparently distinct from all the 
bisporous species. W e have seen the floccose mycelium before, but 
•without perithecia. Hitherto we have not been successful in de- 
tecting or identifying the conidia. Destructive to the vines in 
Australia, but there is no evidence on which to connect it with 
Oidium Tuckeri , but, on the contrary, the floccose mycelium is much 
more woolly, and commonly sterile, at least in so far as we have 
seen specimens. Leaves and twigs sent to us from Australia last 
year, with a thick cottony white mycelium, but without fruit of any 
kind, was probably the same species. It has every appearance of 
being a dangerous pest. The methods adopted here of sulphuring 
Oidium Tuckeri should be tried perseveringly, and the disease 
stamped out at once, if possible. 
Agaricus (Pleurotus) clitocyboides, Clce. Sf Mass. 
Pileo convexo-depresso, tenui, glabro, laevi, ochraceo-pallido, 
demum rufescente, margine membranaceo, leniter striatulo. 
Stipite ascendente, curvulo, subgequali, solido, utrinque sub- 
incrassato, pallidiore, deorsum albofloccoso, disco carnoso. 
Lamellis confertis, tenuibus, longe decurrentibus, vix latis 
albis. Sporis ellipticis, 5x2 /x. 
On old fern logs. Gipps Land. (Tisdall, 125.) 
Pileus 2 in. Stem l|-2 in. long, 2-3 lines thick. 
Agaricus (Lepiota) stenophyllus, Cke. Sf Mass. 
Pileo carnoso, molli, e heemispherico applanato, cute fusco, 
in squamas adpressas diffracto ; margine incurvo. Stipite pro- 
cero, bulboso, fistuloso, glabro, albido, annulo supero deciduo. 
Lamellis linearibus, liberis, perangustis, albis. Sporis ellip- 
ticis, 12 X 7-8.
