26 Messrs. Berkeley and Broome on British Fungi. 
* Tilmadoche mutabilis, Rtfki. Physarum nutans, Pers. 
This is very properly ‘separated by Rostafinski from Phy- 
sarum, in which genus it was always a “‘ vexata queestio.”’ 
1701. Ostracoderma pulvinatum, Fr. Syst. Mye. ii. p. 214. 
Sibbertoft, 1873. On an old sack which had been lying on 
a dunghill. 
Looks at first sight like a white Diderma (Chondrioderma, 
Rtfki.), but not gelatinous in a young state. 
Spores 0003 inch long. 
1702. Gleosporium Hendersoni, B. & Br. Hypophyllum, 
sparsum; gelatina placentiformi ; sporis oblongis; nucleo 
colorato. 
On orange-leaves in a conservatory. Milton, Mr. J. Hen- 
derson. 
Spores ‘0005-0006 inch long. 
1703. G. viole, B. & Br. Maculis pallidis demum albis ; 
pustulis paucissimis vel solitariis, sporis attrantiacis in matri- 
cem effusis. 
On leaves of violet. Glamis, Rev. J. Stevenson, no. 893. 
The effused spores, especially when developed on large white 
spots, make it a very striking species. 
1704. Béctridium acutum, B. & White. Candidum, para- 
siticum ; floccis deorsum attenuatis, apice acutis 1-3-septatis ; 
articulo penultimo tumido. Sc. Nat. iv. p. 162, tab. 2. 
fig. 4. 
“On hymenium of Peziza cochleata. Perthshire, Dr. Bucha- 
nan White. 
Distinguished from Bactridium helvelle by its constantly 
very acute apex and attenuated base. A specimen from the 
same locality sent by Mr. Stevenson had not the same 
parasite. 
PuatTe III. fig. 2. Threads, magnified. 
1705. Cylindrosporium longipes, Preuss, in Sturm, FI. iii. 
29, tab. 35. 
On the shell of a walnut. Perthshire, Dr. Buchanan 
White. 
The base of the stem, as in Preuss’s figure, is dark, the upper 
part hyaline and breaking up into cylindrical spores, abso- 
lutely truncate at either extremity. This is probably Chalara 
fusidioides, Sace. Corda’s plant seems different, being white 
throughout, 
1706. Trichobasis Lynchit, B. in Gard. Chron, Aug. 25, 
1877. Maculis parvis pallidis; sporis sparsis raro confluenti- 
bus; pseudosporis flavis obovatis pulcherrime echinulatis ; 
stipite brevi.
