New zealand fungi 31. Capnobotrys, an anamorph of metacapnodiaceae

Abstract

Seven taxa which produce a Capnobotrys anamorph are illustrated and described. Two of these are described in the teleomorph genus Metacapnodium, namely M. moniliforme and M. dingleyae sp.nov. Other species are Capnobotrys atro-olivacea sp.nov., C. australis sp.nov., C. laterivecta sp.nov., C. pacifica sp.nov., and C. paucispora sp.nov. All but C. laterivecta and C. paucispora produce a Capnophialophora synanamorph. The Metacapnodium teleomorph of Capnobotrys atro-olivacea is briefly described but is not given nomenclatural status for lack of adequate material. Metacapnodium moniliforme also produces a Capnosporium synanamorph. Hyphae can fragment schizolytically in Capnobotrys atro-olivacea. The morphology and pleomorphism of Antennaria guava Cooke (Ȧ Metacapnodium guava (Cooke) comb. nov.), Capnodium crassum Pat. (≡ Metacapnodium crassum (Pat.) comb. nov.), and Phragmocapnias smilacina Mendoza (≡ Metacapnodium smilacinum (Mendoza) comb. nov.) are discussed after a study of type collections. The circumscription ofMetacapnodiaceae is discussed and named and unnamed species circumscribed in DAOM are listed and their pleomwphism is indicated. The broad or narrow host preference shown by species ofMetacapnodiaceae in New Zealand is discussed. © 1981 Taylor & Francis Group, LLC.
