gallers on Adoxa

Dichotomous table for gallers on Adoxa moschatellina

by Hans Roskam

1a Bulging or expanded thickenings caused by smut- or rust fungi => 2

1b Above ground organs often with many small, glass pearl-like, mainly 1-celled wart-shaped galls. Synchytrium anomalum

2a Malformations caused by fungi fruiting at gall surface => 3

2b Bulges on shoot parts above or below ground, containing black smut spores. Melanotaenium adoxae

3a Malformation covered with aecia => 4

3b The fungus develops only dark brown sori with 2-celled telia. Puccinia adoxae

4a Aecia on leaf underside rather uniformly distributed or on petioles and stems loosely distributed on ± thickened pads. Puccinia argentata

4b Aecia, as in previous rust; uniformly distributed, more dense or loose, usually over large areas and soon systemically infected, pale plants. Puccinia albescens
