The very rich material of this fungus has made it possible to give 

 some additions to the diagnose of this species (1. c.) made after the last 

 stage of the development of the fungus (compare: "On decaying leaves 

 of Carica Papaya"). — On the green leaves the infection is very con- 

 spicuous because they are speckled with plenty of until 3 mm. broad 

 spots which are glaring yellow-white, especially on the over-side, while 

 on the under-side they will soon be filled by the outbreaking sporodochia. 

 These are from the beginning brown-yellow, ceraceous, but by and by 

 they are always becoming brown-black. The spores from our specimens 

 were as a rule one-celled, and many of these were seen germinating 

 with until 3 germinative hyphae (see the figure!). Hence cross-walls are 

 not always to be found. In our specimens they were upon the whole 

 rare and indistinct. After this Pucciniopsis Caricae is very closely related 

 to the genus Epidochium Fr. — The longest spores were measured 

 to 27 /i.

Stilbum (Stilbella Lindau) Heveae (Zimmerm.) Sacc. et P. Sacc. 

 Bull. Inst. bot. Builz. 1901 p. 21. This pretty hyphomycetous fungus with a 

 shining ruby-coloured base is described from Buitenzorg, Java, found on Hevea 

 hrasiliensis. As all characters exactly agree and the fungus is upon the 

 whole very characteristic there is — even if our specimens reached until 

 2 mm. in height (while about 1 mm. for the Javanian) — no doubt about 

 the species-identity of the two forms. — On stumps of wood.
