"West. H. C. no. 913/' which is on u Abies," surprisingly yielded 

 1)0 tli the B and C spores of D. occulta. 



B-spores — Pycnidia gregarious, immersed, thick- 

 walled above, convex, black, erumpent in short hysterii- 

 form groups. Spores numerous, filiform, but thickened 

 subclavately upwards, falcate or hamate, obtuse at apex

attenuated below, pluriguttulate in the 



upper 



half, 32-40 x 2 -ft at the widest part; sporophores short, 

 papilliform, rising from a thick soft pale-brownish 

 stratum. (Fig. 4 ? 6.)

The same exsiecatum (Fung. Gall. exs. no. 1727!), as well as 

 tbid. no. 1735! (under the name €i Phoma strobilina, Desm. PL 



Cr. Fr. 1876 ") on the same host, yielded the C-spores. 



C->pores — Pycnidia imperfect or rather with no 

 evident pycnidial wall, convex, irregular, for the most 

 part appearing mouthless, black, rugulose, often erum- 

 pent in an hysteriiform manner, surrounded by the 

 laciniae of the epidermis. Spores fusoid, fish 

 torpedo-shaped, acute at both ends, with one or more 



guttules, 10-14 x 2-3//.; sporophores acicular, 10-15 x 



1 //., rising from a thick brownish stratum. (Fig. 4, c.)

It will be noticed that these spores are exactly what Saccardo 

 describes for his Phoma conorum (Syll. iii. 150); his " basidia 

 uncinata, 24 x 1 ji r * are no doubt the B-spores, though they 

 seem more like the usual B-spores of a Phomopsis than the un- 

 usual ones described above. Perhaps both kinds occur. The 

 C-spores are flattened, as if cut out of thick cardboard, so that 

 in profile they look distinctlv narrower, and are often curved; 



haped.

 There was no true pycnidium : the black mass seemed 



occur 



to be composed entirely of spores 



It was observed that all 

 lines, and often burst the epidermis rimosely, exactly as the 

 ascophoroue stage of D. occulta does at times.
