THE GENUS MYCOPORUM. 827 
Ar 
by Dr. S. Kurz in 1871, and sent to Mr. Currey with some 
fungi from Calcutta. They are very singular and remark- 
able plants, apparently referable to the genus Mycoporum of 
Flotow, although they possess peculiarities which lead one to 
doubt whether they ought not to constitute a separate new genus. 
Both are, so far as my present knowledge extends, undescribed, 
and may be characterized and designated as follows :— 
1. MvcoPoRUM MELASPILON, Leight., n. sp. 
Thallus albidus, tenuis, subfurfuraceus, continuus aut subevanescens, 
linea nigro-fusca limitatus; apothecia atra vel fusco-nigra, irregula- 
riter congregata, 8-12- vel plurinodulosa, plano-depressa, excipulo 
communi involuta; noduli rotundati, plano-depressi, interne gru- 
mosi, arthonoidei, virescentes, opaci, continentes 7 ascos pyriformes 
incolores; paraphyses nulle ; spore 8, incolores, cylindraceo-fusi- 
formes, 13-septate, maxim. 
On bamboo, Yomah, Pegu, Dr. S. Kurz. 
The thallus appears to be composed of pale gonidia, and is 
either persistent or more or less evanescent. The apothecia look 
like irregular black spots or macule—under a microscope, com- 
posed of eight or twelve or more round, plane, depressed nodules 
clustered together and covered with a brownish black continuous 
membrane or excipulum, which is depressed or sunken in the in- 
terstices between the nodules. On viewing a single nodule hori- 
zontally with transmitted light, it appears of an opaque green hue, 
and contains seven colourless pyriform asci, six of which are ar- 
ranged at intervals around a central seventh. A vertical section 
shows the nodule to be composed of a thickish green grumous 
mass, darker on the outer surface, in which are imbedded the asci. 
2. MycoporuM CIRCULARE, Leight., n. sp. 
Thallus albidus, tenuis, continuus, subfurfuraceus, linea nigro-fusca 
limitatus; apothecia consistentia e 6-7 nodulis, atris, rotundatis, 
subconvexis, verruciformibus, minutis, in circulum dispositis, primo 
aspectu nudis at realiter coopertis, excipulo communi interstitialiter 
depresso; noduli interne grumosi, virescentes, opaci, continentes 6 
ascos rotundatos; paraphyses nulle ; spore 8, incolores, maxime, 
oblong aut sublineari-oblonge, muraliloculares, 13-septatz, loculi 
3-4-5 in singulis seriebus.

A still more singular plant than the preceding. The thallus 
consists of pale gonidia. The nodules are arranged in minute 
gem-like circles, in number from six to seven, and are like minute
