NEW SOUTH WALES FUNGI. 



By D. McAlpine. 



(Communicated hy R. T. Baker, F.L.S.) 



(Plates XXVI. -XXVIII.) 



The following seven fungi sent by Mr. R. T. Baker, of the 

 Technological Museum, occur on the leaves or bark of indigenous 

 plants. Four of them are new to science, two are new to the 

 colony, and one has been previously recorded from a different 

 locality. 



FusARiUM BYssiNUM, n.sp. — Byssoid Fusarium. 



(Plate XXVI., -figs. 1-2.) 



Hypophyllous. Pustules pulvinate, gregarious, here and there 

 confluent, firm, byssoid at base, at first flesh-colour finally bright 

 orange-3'ellow, often with small cup-shaped depressions on top, 

 generally circular and 2-3 mm. in dia. Hyphfe hyaline, densely 

 compacted, slender, about I-I^/li thick. Conidia hyaline, fusiform, 

 straight, pointed at both ends, continuous, rarely one-septate, 

 11-14 X li-2;x. 



On leaves of Desmodium sp. Jul3^ Murwillumbah, N.S.W. 

 (Baker, 2). 



This is a very striking form, from its size and bright appearance. 

 Ramularia Desmodii, Cke., (Fusisporiu7n pubescens, B. & C), and 

 Cercos2}ora Desmodii, Ell. & Kell., occur on the leaves of this 

 genus, but are quite distinct. There is an orange Fusarium {F. 

 hypochreoideum, Cke. & Mass.) on fading leaves of Ficus in 

 Queensland, but the pustules are much smaller and the conidia 

 stouter. In F. aurantiacum, Sacc, the gonidia are straight and 

 not pointed at the ends.
