256. — Botryosphaeria inflata Cke. & Mass. 



Thwaites 542 was left undescribed by Berkeley and Broome, 

 and was subsequently named Botryosphseria inflata by Cooke 

 and Massee in Grevillea, XVII., p. 42. Their description is 

 " Peritheciis cortice interiore nidulantibus, demum rimoso- 

 erumpentibus, papillatis, glabris, atris, contextu coriaceo ; 

 rimis arete conniventibus, graphideis, flexuosis ; ascis clavatis, 

 octosporis. Sporidiis biserialibus, ellipticis, utrinque obtusis, 

 medio inflatis, continuis, hyalinis, 33-35 X 10 ^." 



The specimens are somewhat peculiar, in that the pieces of 

 bark are covered by a thin, compact, grayish-white film. This 

 is a layer of fungus hyphse, and, judging from some specimens 

 of a scale insect embedded, in it, may be an immature Septo- 

 basidium. It is not connected with the Botryosphseria, but 

 may account for Cooke and Massee's " rimis graphideis." The 

 stromata are immersed in the cortex, circular or oval in plan, 

 up to "8 mm. diameter, only slightly erumpent, raising and 

 cracking the outer cortical layers, usually in narrow, linear 

 cracks. The stromata are black, with sHghtly projecting 

 ostiola, parenchymatoas. The perithecial cavities are scattered 

 or crowded, up to 0-3 mm. diameter. The asci are clavate, 

 thick-walled at first, with biseriate spores, the sporiferous part 

 measuring about 30 X 16 ^.. Numerous paraphyses are 

 present. The spores are narrow-oval to lanceolate, ends 

 obtuse, hyaline, 20-30 x 6-8 jjl. They appear to be somewhat 

 immature, and are not more inflated in the middle than spores 

 of this type so often are. 



In a recent collection, on Cedrela toona, the spores are 

 18-25 X 6-8 tA. 



257. — Physalospora asbolae Cooke. 



Part of Thwaites 307 was marked Sphseria asbolse by Ber- 

 keley, but he did not publish the name, probably because the 

 specimen is in such bad condition that a definite determination 

 is impossible. Cooke discovered it in Berkeley's herbarium, 

 and published a description as Physalospora asbolae B. & Br. 

 in herb. (Grevillea, XX., p. 82). He gave the spore as 18-20 

 X 10 ^. I was unable to obtain anything determinable from
