NOTKS ON MYCRTOZOA 85 



Trichamphora pezizoidea Jungli. In Junghuhn's Java type the 

 sporangia are discoid, or saucer-shaped, on long translucent red- 

 brown stalks ; the capillitium extends from wall to wall in branching 

 and anastomosing strands, varying in thickness, with many broad 

 expansions, which are free from lime, or, as Rostafinski expresses 

 it, '* the tubes are empty." The absence of lime in the capillitium 

 was taken as one of the chief characteristics of the genus, and it was 

 borne out by other gatherings from different parts of the globe. A 

 specimen found in Java by Dr. Nyman in 1898 was not in accord 

 with this definition ; although in other respects agreeing with the 

 type, the capillitium had the character of that of a Physanim. ; it 

 contained numerous ovoid or fusiform knots densely charged with 

 lime-granules, and connected by slender hyaline threads. In Sep- 

 tember, 1899, Dr. Jahn, of Berlin, kindly submitted to me for 

 inspection a specimen which had been collected in German East 

 Africa by Standt in 1897. In general features this also agreed with 

 the type of T. pezizoidea, except that the capillitium consisted 

 mostly of broad, branching, somewhat straight bands, charged 

 throughout with lime, such as we associate with the genus Bad- 

 hamia ; a few rounded lime-knots connected by hyaline threads 

 similar to those in Dr. Nyman's specimen were here and there 

 present; the spores measured 15 fx, and were more strongly spinose 

 than any of those described in the Brit. Mus. Cat. (p. 90). On a 

 careful examination of the Sumatra specimen referred to on the 

 same page of the Catalogue, the capillitium is found to be not 

 entirely free from lime, but it is in such small quantity that it had 

 previously been overlooked ; in the Ceylon specimen, traces of lime 

 can also be seen in the broad expansions of the capillitium-threads. 

 Thus, in the eleven examples of the species that have come under 

 our notice, four have more or less abundant calcareous deposits in 

 the capillitium, while in seven the lime cannot be detected. When 

 we consider how frequently we meet with limeless specimens of 

 some species of Physaram., notably in P. nutans, the grounds for 

 placing T. pezizoidea in a separate genus appear to be insufficient. 

 We are dealing, no doubt, with a species of which we have only a 

 few examples ; but, judging from the material we possess, it takes 

 its place in the genus Physanim. On comparing the Java and East 

 African specimens with some examples of Physanim calidris, the 

 resemblance of the two species to each other is striking ; indeed, 

 the principal difference seems to be in the larger size and saucer- 

 shape of the sporangia in T. pezizoidea, and in the larger, darker, 

 and more spinose spores. 



Chondrioderma simplex Schroet. (PI. 419, fig. 1). In a former 

 notice (Journ. Bot. 1895, 324) I described a species which I sug- 

 gested might be C. simplex of Schroeter. The yellow-brown Plas- 

 modium was found on Sphagnum on a wild moor in Wales by 

 Mr. Saunders, who collected and protected it until it changed to 

 red-brown sporangia. In July, 1899, when rambling over an open 

 common near Aberdeen, we came upon three patches of yellow- 

 brown Plasmodium, each about two inches across, on Sphagnum and
