MUSCI AND НЕРАТІСЖ RECORDED FROM JAPAN. 161 
DRUMMONDIA, Hook. 
41. D. CLAVELLATA, Hook. 
With capsules some time past maturity and empty, * Challenger’ Exp. 
The specimens agree with American, but are a little more robust. 
AULACOMITRIUM, gen. nov. 
Theca apicalis, æqualis. Folia perichetii in vaginam exsertam convoluta. Calyptra 
mitriformis, plicata. 
42. А HUMILLIMUM,sp.n. (Plate LI. figs. 1-5.) Czespitosum. Caulis simplex erectus. 
Folia patentia sicca appressa lanceolata linealiaque, apice subacuminata integerrima, 
nervo angusto in mucronem pungentem excurrente carinata, marginibus late recurvis, 
e cellulis rotundatis parvis obscuratis, basi ad nervum paucis oblongis areolata; peri- 
cheetialia duplo longiora late convoluta obtusa. Theca breviter exserta brevis ovalis, 
operculo conico rostrato, demum evacua subplicata turbinata, peristomio dentibus 16 
per paria approximatis, siccitate revolutis, teneris, fuscis. Calyptra thecam totam 
obtegens, pluries plicata, basi multifissa. 
Gathered by Maingay. The specimens are all embedded in earthy matter. The 
Macromitriwm calycinum gathered in imperfect state by Textor and enumerated by Van 
der Sande-Lacoste probably belongs to this; it is without locality. 
Caules 3 mm. alti, laxe pulvinatim aggregati. Folia 1-13 mm. longa, olivacea fusces- 
centia. Perichzsetium fere 2 mm. longum, setam fere totam involvens. Тһеса 0:50 mm. 
longa, collo nullo, a membrana tenera cellulis homomorphis condita. Calyptra 1 mm. 
longa. 
The habit and foliage of this small Moss is similar to that of those species of Zygodon 
which generally agree with Z. viridissimus; but the capsule, which at length becomes 
turbinate, with its small membranous teeth, and the plicate mitriform calyptra remove it 
from that genus. Тһе vaginate perichzetium is a character found neither in Orthotrichum 
nor in Macromitrium. 
A. CALYCINUM, Mitt. (Macromitrium calycinum, Mitt. in Journ. Linn. Soc., Bot. iii. 
Supp. 49) is another species of this genus; its capsule is smooth, longer and narrower, 
and its peristome, so far as сап be seen, has equidistant teeth; its calyptra, seen only ina 
young state, is finely striate. Of the male inflorescence nothing is known, and the state 
of the specimens is insufficient to show whether the fertile stems are independent in their 
origin, or, as was supposed in the Ceylon specimens gathered by Gardner and again by 
Thwaites, they arise from a creeping primordial stem ; these appear to have grown on 
trees, but in the Japanese species appearances are against their habitat being arboreal.
