1270. Ustilago pinguiculae Rostrup 90 e ''\ Syll. IX ^^^ 



Soris pallide rufo-violaceis, sporis subhyalinis, tenuiter reticulatis, 

 globosis, 5—6 ," diam. vel ovoideis 7—8 h X 6 P-. In antheris. 



Is much like the two preceding species, the spores occur in the 

 anthers in June— July, and the mycelium is perennial in the host- 

 plant. No doubt it is quite common but rather inconspicuous. Abroad 

 it has been recorded from Norway (Alten see Vgr. 02 "'), Sweden 

 (Gotland see Juel 96 =^3 fi, Vgr. 00 b) and Russia (Oesel see Vgr. 03 '^). 

 Winter (Hedwigia 1878 '«) and Schellenberg (11 " c. icon.) have found 

 it in many places in Switzerland on Pinguicula alpina while P. vul- 

 garis growing close by was not infected, accordingly there seems to 

 be more form. spec, within this species.

The mycelium of this species as also of the above-mentioned one 

 penetrates the host-plant causing it to be lower in growth and most 

 frequently to produce only one head. Not uncommon from May — 

 August.
