155 
were examined, and from these the following description is 
Pycnidia epiphyllous, scattered or in little crowded roundish 
groups, covered by the epidermis, then erumpent, globose, 
slightly papillate, at length collapsed, black, somewhat shining, 
00-150 » diam., pierced by an apical pore. Spores cylindrical, 
often curved, rounded at both ends (sausage-shaped), apparently 
biguttulate, quite colourless, 8+5-9-5 x 2:5; sporophores 
not seen. (Fig. 8d.) 
On leaves of Arbutus Andrachne, Crimea. 
The biguttulate appearance is due, not to the presence of 
oil-guttules, but to the fact that the protoplasm is retracted to 
each extremity of the spore, leaving the middle part as a vacuole. 
This species is similar to Macrophoma maculiformis, Sacc. = 
Sphaeropsis maculiformis, Cooke & Harkn., on Arbutus Menziesii 
(see Grevill. ix. 82), but has different spores. 
After these may be placed a few species which are either 
indeterminable, or were merely named in error. 
905. Phoma nyssocarpa, Cooke. 
Phoma nyssaecarpa, Cooke, in Grevill. vii. 32. 
There is a good supply of the pericarps of these fruits (Nyssa 
capitata), in Rav. Exs. no. 2133!, covered with clusters of little 
brownish-black pycnidia (or perithecia), but no trace of spores 
of any kind could be obtained from them. 
907. Phoma pomorum, Thiim. 
There is no specimen of Thiimen’s in the Herbarium, but 
there are several others issued under this name, all of them 
showing hardly anything but young Diplodia malorum, Fckl. 
941. Phoma Agapanthi, Sacc. 
Sphaeropsis Agapanthi, Thiim. Contr. Myc. Lusit. no. 319. 
Thiimen’s exsiccata (legit Moller), including the type specimen 
named in his own handwriting, show little but brown knots of 
mycelium, accompanied by a quantity of brown creeping threads 
and numerous loose spores: but no spores were seen attached 
to hyphae or in pycnidia. It is probably one of those species of 
Cladosporium which form a basal knot to the conidiophores. 
945. Phoma macrothecia, 7'hiim. 
Phoma macrothecia, Thiim. in Flora, 1876, p. 571 (Thim. 
Mycoth. Univ. no. 680 !). 
This is nothing but Darluca, parasitic on the uredo-sori of 
Uredo Moraeae, Kalch., on leaves of Moraea grandiflora, Eckl. 
— Homeria collina, Vent. var. y, ochroleuca, Baker.
