VIII. FUNGI. 
38. LEPTOSTROMA, Fries. 
Minute, obscure Fungi, consisting of depressed, irregular or orbicular 
masses, covered with a thin perithecium that falls off by a transverse rupture, 
leaving a thin lower half. Spores simple, minute, borne on sporophores. 
Little-known Fungi, of which some species are supposed to be forms of other polymor- 
phous genera. 
1. L. litigiosum, Desmazieres j — FI. N. Z. ii. 193. Perithecia sub- 
rotund, very minute, punctiform, scattered or conglomerate, brown-black, at’ 
length entirely splitting off. 
Northern Island : on dead Fern stems. A doubtful identification. Mr. Berkeley adds 
that there are two forms, one smooth, the other strongly granulate. (Europe.) 
39. PHOMA, Fries. 
Minute Fungi, forming pustules on wood, leaves, stems, etc. Perithecium 
punctiform or subglobose, often spurious, discharging the minute simple 
spores by a small orifice at the apex. 
A genus of numerous species. 
1. P. fallax. Berk, in FI. N. Z. ii. 193. Perithecia forming scattered or 
crowded; minute, discoid spots, when dry black, when moist brown, thin and 
transparent above. Spores oblong, subcymbiform ; hyaline xyg-g- in. long. 
Northern Island : on berries of Rhipogonum, J. D. II. 
2. P. acmella, Berk, in FI. N. Z. ii. 193. t. 106. f. 10. Perithecia 
forming brown specks on both sides of the leaf, depressed, brown, darkest in 
the centre. Spores about -3 i 1L - long, oblong, attenuated, but obtuse at 
each end. 
Northern Island: on leaves of Corgnocarpus, J. I. H., with Sphceria acetabulum, of 
which it is perhaps a form. 
40. HENDERSONIA, Berk. 
Microscopic Fungi. Perithecia subglobose, with often a terminal pore. 
Spores 2-multiseptate. 
A considerable British and exotic genus. 
1. H. hyalospora, Berk, in FI. N. Z. ii. 194. 1 . 106./. 8. Perithecia 
forming minute, black, shining dots upon bark, sometimes slightly papillate, 
generally without a pore. Spores x / 5 0 in. long, hyaline, linear, obtuse at 
each end, 3 -septate. 
Northern Island : on bark of Olea, Colenso. 
2. H. microsticta. Berk, in FI. Antarct. 170. if. 68. /. 1. Perithecia 
minute, black, globose, covered with the epidermis. Spores pellucid, irregular, 
generally lanceolate, acute at both ends, 3-septate. 
Lord Auckland’s group and Campbell’s Island : on scapes of Anthericum, 
J. D. H.
