This has gained grounds for changing the prior trends set for the teliospores epidemiology.
Germinations of teliospores were obtained on 1% water agar (WA) supplemented with the antibiotic tetracycline.
Anther-smut diseases cause both male and female flowers to produce anthers that are filled with fungal teliospores (the ovary becomes rudimentary in females).

alba) showed no obvious differences in teliospore morphology, pattern of teliospore germination, or sporidial size and shape.
pulverulent; TELIOSPORES ellipsoid or clavate, 40-60 x 22.
The microscopic observation of the flower powder showed acute hairs, spherical, echinate pollen grains, teliospores of Puccinia malvacearum--a typical parasite of Malva sylvestris that is very common in plants in the Ciudad Universitaria and also appears in the observation made of Althaea officinalis- and parts of subepidermis and mesophyll with oxalate druses (Figure 9).
Based on material on Codiaeum imported from Ghana into the Netherlands, Boerema and Link (1979) determined that the aecioid sori and spores were actually telia and teliospores, thus they described this species in the teleomorph genus Dietelia.
Also, the American specimens contained more one-celled teliospores than the Asian specimens, which were far more likely to contain two-celled teliospores.
Further, it converts the plant's developing seeds into "bunt balls"--encapsulated, powdery, black masses containing over 10 million teliospores, which are easily dispersed by wind and rain or mechanical harvest and transport.
After disease infection, mycelia grow within the developing rice kernel, eventually consume the endosperm, and produce numerous spherical black teliospores (Whitney and Frederiksen, 1975).
Infected plants produce flowers with anthers containing only fungal teliospores, and spores are transmitted from flower to flower by pollinators.
