In one specimen from near Echo Hill, with a stem about 6 cm. high and an 
umbonate convex pileus 2 cm. in diameter, the rather stout stem expands 
gradually upwards and the universal veil is seen almost intact. The veil covers 
the whole of the pileus, both disc and gills, and descends on to the stem, a 
little below the level of the lowest portion of the gills, as a grevish to dirtv 
whitish friable rugose membrane, which has ruptured in half its circumference 
to form a spreading upwardly directed superior ring a mm. eej On the stem 
below at intervals are further broad fragments of the universal veil and at the 
base which is not definitely bulbous are volva-like fragments. Where the veil 
leaves the outer convex surface of the gills, these turn in horizontally for 3 mm., 
forming a horizontal rim of uncovered gill plates so closely set as to resemble

the leaves of a book. The sides of the gills facing the stem then ascend almost 
at right angles but with a slight concavity towards the stem to the disc leaving 
an ample space between them and the stem, whien latter is here coarselv striate! 
Spores of this specimen spherical to irregularly spherical, dark-fuscous, 5.5 to 7 a. 
In another specimen the veil has left imperfect rings on a delicate stem. The 
attachment of the gills to the disc is very narrow: the gills, however, soon assume 
their average diameter and may do so abruptly, thus leaving a free edge internally 
facing the stem and another free edge externally where the veil leaves the side's 
of the gills, or may be somewhat narrowed internally and externally; sometimes 
they may be perhaps attached to a slight extent to the under aspect of the edge 
of the disc. The above description has been drawn up from fresh specimens 
collected in the Mnsgrave Ranges or their vicinity. At first sight it may seem, 
from the great differences in spore measurements and shapes, that we mav be 
dealing with two species, especially as the Echo Hill specimen is distinctly more 
robust than the others (which are numerous). It i s in fact matched to some 
extent by two other coarse specimens, one from Miller Creek near Mount Eba.
