HIMALAYAN LEAF FUNGI. 



Volutella. Sj). {?) — A black discoid fungus on coriaceous leaves, 

 the disc beset with long rigid black bristles, which are expanded at 

 the base, is amongst the collection ; but there is no fruit, only a pro- 

 fusion of long slender hyaline threads. It is difficult even to 

 determine the genus with certainty. 



Septotirichum. <S^^.— This production, similar to Septoti-ichuin 

 Steben', Corda, is not a true fungus, but of the same nature as 

 PhyUerium and Erineum. The tufts of moniliform cells appear to 

 burst through the cuticle, as in the pai-asitic Coniomycetes, but 

 there is no evidence or indication that the cells are reproductive, 

 neither have any organs corresponding to spores been found associated 

 with any of the so-called species. They are all sub-tropical forms, 

 and seem to correspond with the Erineum and PhjjUerium of 

 temperate regions. All of these are now regarded as peculiar 

 conditions of the tissues, and will so remain until some reproductive 

 system can be discovered. 



In addition to the foregoing. Dr. Fleming reports that he has 

 met with Pliragmidium hulhosum, gracile, ohtasatum and mucroiiatuiii 

 — Pucciaiu variabilis, umbeUiferarum, and si/ngenesiarum, Coleos- 

 porium jmigue and Peridermium Pini. Specimens of these we 

 have not seen. M. C. Cooke. 



A SPH^RIACEOUS PARASITE ON PEZIZA. 



By J. DE Seynes. 



In the March number of " Grevillea" you have given (p. 143) 

 interesting particulars of a parasite on Pcziza. Permit me to call 

 attention to a case of parasitism of another Sphceriaceous fungus 

 on a living Peziza. This Peziza has not yet been published ; it 

 was found by Dunal on old dog's dung (album groecum). It- is of 

 one millemetre in diameter, between Heshy and ceraceous. One of 

 the sjDecimens I have found presented a little black spot on the 

 external surface. Seen through the miscroscope this black spot 

 appeared to be a perithecium. It was in the form of a barrel, its 

 base intermixed with the parenchyma of the Peziza, with a large 

 ostiolum, and of olivaceous colour. The fungus being too fully 

 ripe exhibited no asci, but the quadriseptate sporidia, also of an 

 olivaceous colour, issued from the apical opening. It seems to me 

 to resemble the genus Lophiostoma. It is clear that this perithecium 

 does not belong to the Peziza alone, for I have found it also on a 

 very young and small specimen of Xyluria hypoxylon only 12 

 millemetres in length. It was placed on the highest, and most 

 tender part. The perithecium and sporidia had exactly the same 

 form and color. It was also ripe and did not exhibit asci. This 

 seems to approach Lophiostoma macroatoiva, in which the sporidia 

 are sometimes quadriseptate, but the sporidia of the present species
