A PYRONEMA FROM QUEENSLAND 
J. W. HERBERT 
Pyronema omphalodes (Bull.) Fuckel., known from 
Europe, North America and Victoria, has not previously 
been recorded from Queensland. Characteristically an 
inhabitant of burnt ground or sterilised soil, it has been 
found in Kalinga Park, Brisbane (A. B. Cribb, 21/4/53) 
on burnt ground. 
The fungus differs from Peziza in the small size of 
the apothecia which are usually less than 2 nun. diameter; 
these become confluent, farming flat irregular masses 
more than a centimetre in diameter surrounded by a white- 
superficial mycelium. The Queensland specimens were 
bright orange, but there is a range from only slightly 
yellowish to an occasional purple tinge. The hymenimn 
of each apothecium is convex. Asci are cylindrical, about 
b50 u x 10-14 u, with 8 spores uniseriate, ellipsoid, 
smooth, hyaline, 10-13 u x 5-8 u: the. paraphyses are stout, 
somewhat thickened at the apices, and about the same 
length as the asci.
