    • Centraalbureau voor Schimmelcultures Correlation of clustering and other morphological characters
    • Centraalbureau voor Schimmelcultures Correlation of clustering and other morphological characters Clade K: sporangia globose to ovoid with papilla and often proliferating internally, large, oogonia, thick- walled oospores, 1–2 elongate antheridia, laterally applied to the oogonium. Sequence analysis shows this clade to be closer to Phytophthora. Sporangia and oogonia may show similarity to Phytophthora, however, zoospore discharge is Pythium-like. The clade represents a genus intermediate between Phytophthora and Pythium for which the name Phytopythium is proposed. P. carbonicum P. ostracodes
    • Centraalbureau voor Schimmelcultures Correlation of clustering and other morphological characters P. multisporum Clade E: P. rostratifingens-clade: globose, proliferating sporangia or globose hyphal swellings. Oogonia smooth P. segnitium-clade: ovoid to elongate, nonproliferating sporangia; mostly a single, hypogynous antheridium. P. echinulatum
    • Centraalbureau voor Schimmelcultures Correlation of clustering and other morphological characters Clade J: only the subclade P. jasmonium-polymastum is morphologicaly distinct: large oogonia with conical spines, thick-walled oospores, large globose sporangia. P. polymastum
    • Centraalbureau voor Schimmelcultures Correlation of clustering and other morphological characters Clade I: No obvious common morphological characters in this clade. Most species do not produce zoospores.
    • Centraalbureau voor Schimmelcultures Correlation of clustering and other morphological characters Clade G: ovoid, internally proliferating sporangia and smooth oogonia. Ornamentation on the oogonia of P. paddicum is unique. Other characters variable. Mainly from monocotyledons in Asia and the USA.
    • Centraalbureau voor Schimmelcultures Correlation of clustering and other morphological characters Clade F: important, fast growing phytopathogenic species with a worldwide distribution. Globose non-proliferating sporangia or hyphal swellings present. Most species do not or rarely produce zoospores.
    • Centraalbureau voor Schimmelcultures Correlation of clustering and other morphological characters Clade H. Very large, ovoid to elongate, internally proliferating sporangia and ornamented oogonia. P. helicandrum P. undulatum

P. grandisporangium P. insidiosum
    • Centraalbureau voor Schimmelcultures Correlation of clustering and other morphological characters Clade A: P. adhaerens cluster: filamentous non- inflated sporangia, very slow growth. From algae. P. aphanidermatum cluster: filamentous inflated sporangia, very fast growth, often intercalary antheridia. From dicotyledons in warmer regions. P. porphyrae P. deliense
    • Centraalbureau voor Schimmelcultures Correlation of clustering and other morphological characters Clade B P. vanterpoolii cluster: filamentous, inflated sporangia; smooth oogonia. Most other characters variable. Predominantly from grasses. P. apleroticum-cluster: filamentous non-inflated sporangia, smooth oogonia, moderate growth rate.
    • Centraalbureau voor Schimmelcultures “Species specific” morphology: - ornamentation: P. paddicum, P. carbonicum, P. solare, P. jasmonium - segmentation: insidiosum - deciduous sporangia: intermedium, attrantheridium P. intermedium
    • Centraalbureau voor Schimmelcultures Characters that show no significant correlation with clustering: • sporangium size • antheridium origin and number • oogonium size • oospore wal thickness • apressoria • heterothallism • etc.
    • Centraalbureau voor Schimmelcultures Conclusions: • Sporangium type is evolutionary significant • the contiguous type is a distinct sporangium type • oogonium ornamentation is polyphyletic but shows correlation with some (sub-)clades • some clades are characterized by a subset of characters • most characters do not correlate with evolutionary patterns but they are useful for identification
