Asterotexis/Schyzothyrium
Esquivel-Rios Eduardo, 23-09-2012 00:12
Hi All.

In 1993 i found a Foliar Disease of "Chayote" Sechium edule, and others Cucurbita spp. cultivated, called "Black Star Spot", and classifed as Schyzothyrium sp. The fungi grows over the leaf cuticule and apparently not penetrates host tissue, as a comensal. The fungi tissue can cover all foliar lamina, causing poor photosintesis al chlorosis  of leaf. Recently, Guerrero, . et al (2011) revised this fungi and determinates is Asterotexis cucurbitacearum (Rehm) Von Arx. because found evidences of real parasitism. The two especies are identical, and the difference is the cuticule penetration by haustoria. May be any can help in this ..?
