32 MM. L.R. AND C. TULASNE ON THE TREMELLINEOUS FUNGI 
being divided by transverse walls into four cells or stumps 
which throw out above long and fertile spieules. (See De Bary's 
‘Morph. u. Physiol. der Pilze’ &c., p. 116, fig. 47,a-c.) 
It is a condition common to these three types that the basidium 
and its appendices are filled with a granular and not very trans- 
parent plasma, which is wholly employed in forming the spores, 
so that when the latter have become perfect and mature the 
organs that have produced ‘them are quite empty and transpa- 
rent. It is moreover observed that the spicules are generally 
far thicker than is mostly the case amongst other Hymeno- 
mycetes. 
IL An hymenium resembling that of the Dacryomycetes is 
found also in the Calocere, which, on account o? their linear shape, 
have for a long time been mixed up with the Clavarie ; but the 
real or legitimate affinities of the former are now understood and 
interpreted by the most able mycologists, such as MM. de Bary 
and Fuckel, in the same manner as that already adopted by our- 
selves. (See ‘Ann. des Sc. Nat., 3rd ser., t. xix.) 
In the Zremella helvelloides DC., a beautiful species, the struc- 
ture of which has hitherto remained unknown, we have met with 
basidia that are forked almost like those of the Dacryomycetes, but 
nearly as globose as those of genuine Tremelle. This fungus, 
which M. Fries has justly removed from the Tremelle to his group 
of the Guepiniz, differs nevertheless from several of the latter 
in being fertile on the under surface. In Guepinia Peziza Tul. 
-the hymenium is only spread on the superior and cup-like face of 
the plant, exactly as is usual amongst the Pezize. 
We give here a short description of Guepinia helvelloides Fr.
