Pycnidia incomplete, very numerous and often crowded, roundish, 

 depressed or conical, 250-800 ju diam., becoming pallid, at length 

 elevating and piercing the epidermis in the centre by a minute pore. 

 A-spores fusoid, nearly alwaj^s straight, indistinctly guttulate, 

 8-10 X 2|-3 /u ; sporophores subulate, 8-11 xlai", rising from a 

 thick yello\vi*h-olive or fuliginous stratum : B-spores linear, mostly 

 curvecl or hooked, 16-18 x 1 /x. 



On dead twigs of Lauriis nohilis ; also on the leaves. Kew

The pycnidia are small and very imperfect above. In the Irish 

 specimens, the fungus appeared to be killing the twigs backwards, 

 beginning at the tips, exactly as P. a Hciibicola does. In Mr. Boyd's, 

 A- and B-spores occurred together on the twigs; butonl3^the A-spores 

 on the leaves, in similar pycnidia. The latter ma}^ j^o^sibly be 

 Fhyllosticta Lcmri Westd., for they were thickly spread over the 

 upper sui-face of large brown dry, darker margined, spots, like a 

 normal Pliyllosticta. This Phomopsis is the pyenidial stage of 

 Diaportlie nohilis S. & S.

The spermogonial stage of Diaportlie minuseula Sacc. & Speg. 

 The pycnidium is of the usual character, consisting at first of little 

 except the dusky basal proliferous stratum and the epidermis darkened 

 by a thin brownish mycelium; but afterwards a true and thick 

 pyenidial wall is formed above. 



325, Phomopsis Oleariae, sp. n. 



Pycnidiis superne incompletis, sparsis, \-\ mm. diam., atris, 

 halone pallide brunneo cinctis, erumpentibus. Sp)orulis elliptico- 

 I'usoideis, a latere visis curvis et subclavatis, basi subacutatis, raro 

 guttulatis, 7-8 X 2 yu, sporophoris subulatis, paullo spora brevioribus,

Some of the pycnidia are situated on a blackened patch reminding 

 one of a Diaportlie, but no Diaportlie on Olearia is known. On 

 the same twigs, but not intermixed, was a Spli(srella (?) with long
