258 PUCCINLA 



with a Crown Rust on Festuea ; Kleh.dm and Fischer have since repeatedly 

 confirmed his results. Fischer records /'. Festucae for Festuea rubra and 

 its \ar. fallax, and he connects it with an secidium on Lonicera coerulea 

 and A. nigra. Be states that the uredospores have about six germ-pores ; 

 that the teleuto-sori are situated in the groove of the upper side of the 

 leaf, at first covered by the epidermis which at Length opens by a slit ; also 

 that the teleutospores have a thick-walled pedicel and are much thickened 

 and occasionally conical at the vertex : mesospores were sometimes found 

 intermixed. 



McAlpine found the uredospores with five scattered germ-pores on one 

 face (i.e. probably six or more altogether). His specimens were on Festuea 

 ovina and F. rigida, hut in Australia no secidium on Lonicera is known. 

 He found very commonly, mixed with the teleutospores, mesospores 

 provided with similar processes at the apex. 



Distribution: Central and Northern Europe, North 

 America, Australia.

Uredospores. Sori amphigenous and on the inflorescence, 

 minute, oblong, as much as 1 mm. long, arranged in long lines, 

 on yellow discoloured spots, not often confluent, lemon-yellow : 

 spores globose to broadly ellipsoid, echinulate, yellow, 25 — 30 x 

 18 — 26 ix ; membrane always distinctly colourless. 



Teleutospores. Sori hypophyllous or culmicolous, arranged 

 in long fine lines, a few scattered on the inflorescence, oblong, 

 dark-brown or black, covered by the epidermis; spores clavate, 

 rounded, truncate or obliquely conical above, where the exo- 

 spore may be as much as 4 — 6 (or even 10) /x thick, slightly 

 constricted, attenuated below, smooth, brown, SO — 70 x 12 — 24m; 

 pedicels very short or almost none; paraphyses brown, numerous, 

 curved, surrounding each little group of teleutospores.
