Hab . — In nido vetusto Bombi sp., Kew, April, 1901. 
The Fungus described above appeared among the debris of an old 
nest of a Wild-bee ( Bombus sp.) dug up in the Royal Gardens, Kew, 
after the nest had been kept for about a month in a tin box. The 
perithecia occurred superficially on the bits of straw, &c., composing 
the nest, and were often held together in groups of three or four by 
their interlaced appendages. The wall of the perithecium is pale 
yellowish-brown, and the sulphurous colour of the perithecium is due 
to the presence of the indumentum closely adhering in strands to the 
wall, and completely surrounding each perithecium. The appendages 
originate from the basal cells of the wall of the perithecium ; the cells 
of the wall at the place of origin are sharply marked off from the rest 
by being very thick walled and brownish in colour. The appendages 
are very flexuous, somewhat rigid and shining, with delicate transverse 
septa ; the apex is variously contorted in a more or less circinate 
manner. Each spore seen from the front is orbicular in outline ; from 
the side, broadly elliptical. 
The present species appears to differ specifically from A. nitidus in 
the slightly larger size of the perithecium, and especially in the 
indumentum surrounding each perithecium ; the appendages also in 
A. nitidus are longer, and apparently never spirally contorted at the 
apex as in the present species. The size and arrangement of the 
spores are the same in both species.
