Ethan CrensonHi all, Another find by a friend yesterday in Bro
Salvia leaf parasite

A tiny fungus shaped like globose black grains, only 0.05 to 0.15 mm in diameter, sprouting on the leaves of Salvia jordanii, colloquially known as rosemary, causing a marked yellowing.
Hyphae of the peridoid wall have an angular texture.
Conidia are cylindrical, with rounded ends, mostly with three septa, constricted within them, with brown intracellular pigment and abundant lipid droplets inside, measuring in water:
(14.7) 15.1 - 19 (20) × (6.9) 7.4 - 9.5 (9.7) µm
Q = (1.6) 1.8 - 2.4 (2.5) ; N = 30
Me = 17.4 × 8.3 µm; Qe = 2.1
I admit I'm not sure where the wind is blowing this time. The closest thing I know about rosemary leaves would be Alternaria alternata, but the microscopy doesn't match up at all.
Any feedback from you would be welcome.
Thank you very much in advance.
Best regards.

Re : Salvia leaf parasite
Hi Josep, take a look at Trimmatostroma salicis, found on many plants inc. Salix mostly. Also on Rosemary. Macro and conidia similar. regards
