臺灣黏菌（四）

Myxomycetes of Taiwan IV: Corticolous Myxomycetes

本文報告三十一種生長在活樹之樹皮上的黏菌，其中九種是臺灣的新紀錄種，其學名如下：Echinostelium minutum，Calomyxa metallica，Arcyria annulifera，A. carnea，Hemitrichia karstenii，Physarum leucopus，P. serpula，Clastoderma debaryanum和Macbrideola cornea。其餘種類分屬於下列各屬：Cerariomyxa，Cribraria，Reticularia，Arcyria，Perichaena，Physarum，Didymium和Stemonitis。並以十八個圖版明示其子實體的生長習性和顯微特性。有四個顯然尚未為人發表的種類其分類特性和種名的確定正有待一步的比較研究，其中一種是Cribraria，另外三種屬於Physarum。採用野外直接採集和潮濕培養法採收黏菌子實體，所有的標本皆存放於國立臺灣大學植物系菌類標本室。

Thirly-one species of Myxomycetes that appear on L he bark of living trees are reported. Nine of them arc recorded for the first time on Taiwan: Echinostelium minutum, Calomyxa metallica, Arcyria annulifera, A. carnea, Hemitrichia karstenii, Physarum leucopus, P. serpula, Clastoderma debaryanum, and Macbrideola cornea. Other taxa listed arc those included in the genera of: Cerariomyxa, Cribraria, Reticularia, Arcyria, Perichaena, Physarum, Didymium, and Stemonitis. Their growth habit and microscopic characteristics are demonstrated by figures in eighteen plates. Four apparently undescribed taxa, one of Cribraria and three of Physarum, are described. The taxonomic certainly of them a wait further comparison and investigation. Boths field collections and moist chamber technique were adopted for the fructifications. All the specimens are deposited in the Mycology Herbarium, Department of Botany, National Taiwan University. Taipei, Taiwan, R. O. C., TAI.
