Entylomaster Vánky & R.G.
Entylomaster typhonii Vánky & R.G. Shivas on Typhonium
Sori on hosts in the Araceae, forming leaf spots containing spores agglutinated in irregular balls, embedded in the host tissue.
Spore balls composed of spores only, without a fungal cortex or sterile cells.
Spores yellow, pale yellowish brown or orange-yellow, without blackish or reddish brown tints, produced on the tips of sporogenous hyphae.
Septal pore simple, enclosed by 2 membrane caps.
Host-parasite interaction by complex interaction apparatus with cytoplasmic portions; haustoria absent.
Entylomaster was established for smut fungi with yellow to yellowish brown spores aggregated into spore balls that are embedded in leaves and petioles of Araceae (Vánky & Shivas, 2006). It includes two species, E. typhonii and E. dietelianus (Bubák) Vánky & R.G.Shivas, both known only from their type collections. The latter occurs on Ambrosina bassii L. in Italy.
