Lecidea subhyalina, sp. nov. 



Thallus albus tenius nonnihil squamulosulus ; apothecia 

 electrina pellucida primum planiuscula et vix marginata dein 

 convexa et fere globosa ; sporse (2 — 8 ?) use, incolores, sim- 

 plicis, ellipsoideae, "015 — 02 x 0005 — 009 mm.; paraphyses 

 nullse (proprie sicdictas), epithecium incolor ; hypothecium 

 incolor. Iodo gel. hym. leviter casrulescens dein fulvescens. 



Corticola, Gippsland in Australia. 



The entire hymenium is gelatinous. The apotliecia 

 appear under a Codington lens as little particles of clear 

 amber without any apparent structure. I have not been 

 able to detect more than two spores in each theca, although 

 a presumption is afforded on other grounds that the normal 

 number is 8. There were very few thecae or spores seen. 



Lecidea grossulina, sp. nov. 



Thallus albidus vel pallidus tenuissimus fere continuus ; 

 apothecia sessilia nigra mediocria (latit. circiter 1 mm.), 

 plana et obtuse marginata dein convexa et immarginata ; 

 sporre 8 n?e in thecis oblongo-saccates, incolores, ellipsoidese, 

 1 — septatse, '022 — *034 x "013 — 018 mm. ; paraphyses 

 graeiles distinctse confertse apicibus conghitinatis cserulee 

 nigris interdum fusco-nigris ; hypothecium incolor vel fere 

 incolor. Iodo gel. hym. cyerulescens dein vinose rubens. 



Corticola, Fern-tree Gully in Australia. 



Graphis gypjdia, sp. nov. 



Thallus albidus tenuis hinc inde visibilis ; apothecia tota 

 pallida vel pallid e lutescentia, segregata, prominula, pulve- 

 rulenta (latit. *2 — "3 mm.), ramosa et plerumque stellatim 

 divisa, epithecio rimiformi ; spora3 8 nae incolores obtuse 

 fusiformes, (6 — 9) — loculares loculis mediis interdum semel 

 divisis, "018 — "025 x 006 — *0075 mm.; paraphyses distinctse, 

 crassiusculaa; hypothecium incolor vel pallide lutescens. 

 Iodo gel. hym. leviter vel obsolete ca3rulescens. 



Coiticola, Gippsland. 



In one of Mr. Paton's parcels there were detected traces 

 of a Parmelia, presenting characters so closely resembling 

 those of one sent by Mrs. Roy, of Royston Park, Owen 

 Sound, Ontario, Canada, that I am inclined to identify them. 



The following is a description of the Canadian lichen: — 



Parhelia Royl sp. nov. 



Thallus cinereo — vel cervino-fuscescens, cinereo-rufescens 

 vel interdum obscure olivaceus (K nonnihil flavescens), sub- 

 stellatus, laciniatus, laciniis interdum imbricatis (et tunc 

 latioribus, planis), incisis et lineari-mnltifidis, convexiusculis,
