406 Petch. — Mocharas and the Genus Haematomyces . 
A fourth species was described by Rick from Brazil : 
‘ Haematomyces eximius , Rick, Ascomate gelatinoso , cerebriformi et 
tremelloideo, prorumpente , convolutionibus eras sis, fir mis, globoso, 5 diam., 
castaneo ; ascis cylindraceis, 130x6-8 y ; sporidiis ellipsoid eis , 6-8 y longis, 
4 ijl cr., biguttulatis , apicidatis v. etiam apice truncatis , viridido-hyalinis , dfem 
olivascentibus , biserialibus , unilocidaribas ; paraphysibus filif omnibus, apice 
paulatim minute incrassato , hyalinis , versus pedem viridulo-olivaceis 
And Rick adds ‘ Haemat. spadiceo ajfinis \ a remark which strikingly 
illustrates the futility of comparisons based on descriptions only. 
In £ Fragmente zur Mykologie ’, VI. Mitt., p. 126, von Hohnel writes, 
‘ Another Discomycete genus with an immarginate disc is Haematomyces , 
Berk. This genus appears to me to be an immarginate Ombrophila . 
Presumably those species of Psilopeziza which are brilliantly coloured 
( flavida , aurantiaca , xylogena , aquatic a) would be better regarded as species 
of Haematomyces. 
£ To this genus, no doubt, belongs also Pezizella orbilioides , Feltgen 
( £ Vorstud. Pilzflora von Luxemburg, 5 III. Nachtr., p. 53), which I formerly 
referred to Ombrophila . It must now be named Haematomyces orbilioides , 
(Feltg.) v. H. It corresponds admirably with this genus. 5 
Apparently the accepted idea of Haematomyces is a pulvinate, convoluted, 
or cerebriform stroma, more or less gelatinous or tremelloid in consistency, 
which bears a palisade layer of asci and paraphyses over the whole of its 
exposed surface, without any definite margin. The spores are continuous 
and hyaline. None of the descriptions states explicitly that the asci are 
arranged as suggested, but that conclusion appears to be warranted by the 
inclusion of the genus in the Bulgarieae. Berkeley and Broome made the 
shape of the asci a generic character, but that has been ignored by all 
the describers of subsequent species. 
Berkeley and Broome’s material appears to have been scanty. There is 
a specimen, part of the original gathering, in the Peradeniya herbarium, but 
as for twelve years I did not meet with any species which coincided with the 
current idea of Haematomyces , it was not examined. During 3918, however, 
I collected, in the low country, an ascomycete which formed a pulvinate, 
cerebriform stroma, up to 1-5 cm. diameter, purple-red to flesh colour, 
and somewhat subtranslucent and tremelloid. The whole of the exposed 
surface was covered by a palisade layer of asci. As this species appeared 
to agree with the description of Haematomyces , an examination of the cotype 
was undertaken. 
The cotype in Herb. Peradeniya (Thwaites’ 59 ) was evidently obovate 
when fresh, about 8 mm. high, and 5 mm. broad. It has become laterally 
compressed in drying, and slightly folded towards the apex, but it is 
scarcely f subcerebrinus \ Its colour is dark purple-brown, and its surface 
minutely rough. On cutting sections, it is found that there is no palisade
