Example of Brown Rot (Alternaria passiflorae) on a Passion Fruit vine.
a slime mold ?
New record for NZ. Necrotic areas of living leaves with conidiomata exuding tendrils of conidia, to 60x 4um. Agrees with description in "Fungi of Australia: Septoria by Michael J Priest, 2006". Conidia larger than other species associated with Senecio. Isolated into culture for ICMP.
One of the two Colletotrichum fungi causing the "bitter rot" disease on apples.
One of the new species described last year out of my postdoc work:
A pretty common Colletotrichum fruit spot on banana
Dry rot on swede - Phoma lingam (teleomorph Leptosphaeria maculans)

Dothideomycetes is the largest and most diverse class of ascomycete fungi. It comprises 11 orders 90 families, 1300 genera and over 19,000 known species. Traditionally, most of its members were included in the loculoascomycetes, which is not part of the currently accepted classification. This indicates that several traditional morphological features in the class are not unique and DNA sequence comparisons are important to define the class.
