H. longipes Harkn. Fung. Calif, p. 13. 



Pycnidia thickly scattered, minute, roundish, palhd-brown, 

 opening by a round pore, formed beneath the epidermis which at 

 length splits over the ostiole into 3 or 4 dentate triangular segments 

 (like a Phacidium). Sporules oblong-elliptic, 25 — 30x9 — 12 tx 

 (occasionally up to 34 /f long), with two or three guttules, olivaceous, 

 apiculate, the apiculus rather paler; pedicels long, narrow, curved, 

 hyaline, persistent, up to 80 tx long. 



On the phyllodes of Eucalyptus sp., Perth, West-Austraha, July 

 1913 (no. 37). 



The membrane of the pycnidium is pseudoparenchymatous above, 

 but composed below of pale-olive more or less parallel hyphae. It 

 dehisces by a somewhat papillate ostiole, with a perfectly round 

 pore which is visible below the star shaped opening made in the 

 epidermis. The spores are at first hyaline, then olivaceous and 

 granular, and w^hen mature thin-walled, with 2 or 3 (usually two) 

 guttules. The pedicels are very persistent, long, slender and flexuous. 

 The spores ooze out like those of a Mdmiconium and form a black 

 globule at the mouth, which becomes very large and is ultimately 

 effused on the surface like a black stain. The occurrence of this species 

 in Austraha is, of course, exactly what would he expected, although 

 it was first discovered in America.
