Petch . — The Gemis Endo calyx, Berkeley and Broome . 399 
Microcera has a loose sheath which is longer than the ripe sporodochium, 
and Fusarium has an adherent sheath which envelopes the head of conidia, 
but in both these cases the sheath is not brittle and the hyphae composing 
it are joined by ladder-like connexions instead of being merely cemented 
together. The parallel therefore is not exact. The stalks of E. cincUis and 
E. Thwaitesii suggest an alliance with Stilbum , though the black sheath 
of the first-named is a departure from the usual structure in that genus. 
On the whole Endocalyx would appear to stand best in the section Stilbaceae- 
Phaeostilbeae, though the arrangement of the spores seems to have no 
parallel in that section. 
Rlccoa, Cav. } appears at first sight to resemble Endocalyx : the stalk 
expands at the top into a cup in which the sporophores are produced, and 
the spores are borne along the sides of the latter. But the stalk and cup 
are parenchymatous, and the sporophores are rather widely separated and 
compound, i.e. formed by the fusion of several hyphae : the lateral arrange- 
ment of the spores, as far as can be understood from the description and 
figures, is due to a progressive separation of these hyphae upwards, so that 
the spores are really terminal on the individual hyphae. As in Graphiola , 
the spores are hyaline.
