562 AUSTRALIAN FUNGI, 



S C H I Z O T H I C 11 U M, n.g. 



Sporodochia globose or siibglobose, erumpent, ultimately super- 

 ficial, black; sette septate, thick-walled, erect, straight or slightly 

 curved, few or numerous. Conidiophores obsolete or represented 

 by a minute colourless base. Conidia h3^aline, filiform, straight 

 or curved, 3- or more septate. 



This genus has a dark-coloured sporodochium, but the conidia 

 are hyaline, hence it belongs to the Series Tnhercidariecti rtiiice- 

 dineo', Sacc. Further, on account of the septate spores, it will 

 occupy a place beside Leptotrichum, Corda, in which the conidia 

 are only 1-septate and the setre continuous. 



59. SCHIZOTRICHUM LOBELL?:, n.sp. 



Sporodochia on sooty elongated patches, densly crowded, 

 globose or discoid, erumpent, finally superficial, black, with 

 greyish bloom due to conidia, 130-160 /z diam., composed of com- 

 pact dark olivaceous, closely septate and copiously branched 

 hypliEe 7-9 /i broad; with similarly coloured, projecting, thick- 

 walled setae, simple, septate, not constricted at septa, with usiiall}' 

 rounded and almost colourless apex, 70-95 x 4^-5 fi. Conidio- 

 phores obsolete. Conidia hyaline, filiform, straight or curved, 

 3-6-septate, not constricted at septa, guttulate, very variable in 

 length, average 28-35 x 1-2 yn, but may reach a length of 50-60^^1. 



Sandringham, Victoria; on flowering and fruiting stems as well 

 as leaves of Lobelia gihbosa, Labill.; Dec, 1902; Jan., 1903. 



The black elongated patches are very conspicuous and often 

 very numerous. The soot}^ appearance is due to a perfect net- 

 work of dense olivaceous hyphse which connect the various sporo- 

 dochia. The conidia arise direct from the olive-coloured cells of 

 the sporodochium, or there may be a minute, basal, hyaline cell 

 from which the conidia are detached. The radiating setse may 

 be few or numerous, sometimes none or apparently covering the 

 entire sporodochium, and very occasionally the apex gives rise to 

 a colourless filament, resembling a conidium originating from the 

 basal cells.
