神农架丝孢菌的研究——Ⅳ.尾孢菌属,短胖孢属和色链隔孢属(英文)

作者在前两篇文章里报道了湖北省神农架产的尾孢菌属及其近似属的22个种,本文再报道这一地区的尾孢菌属、短胖孢属及色链隔孢属的4个种,其中1个是新种,即李色链隔孢(Phaeoramularia pruni Guo et Liu,sp.nov.),其模式标本收藏于中国科学院真菌标本室(HMAS)。该新种与寄生于李属(Prunus sp.)植物上的变红尾孢(Cercospora rubrotincta)接近,但后者分生孢子梗窄(2—4.5μm),不分枝,曲膝状折点少(0—1个),分生孢子向顶渐狭,不链生,隔膜多(1—5隔),因此易于区别。

A new species ofSporothrix from calf skin

An isolate from calf skin lesions is described as the new speciesSporothrix catenata de Hoog et Constantinescu. The fungus produces conidia in relatively long chains, and may show late-stage budding.     

Coniosporium perforans and C. apollinis, two new rock-inhabiting fungi isolated from marble in the Sanctuary of Delos (Cyclades, Greece)

Coniosporium perforans and C. apollinis, orginating from marble in the Mediterranean basin, are described as new species of rock inhabiting microcolonial fungi. The morphologically similar species Monodictys castaneae (Wallr.) S. Hughes, Phaeosclera dematioides Sigler et al., and a Coniosporium-like strain are compared using 18S rDNA phylogeny and Restriction Length Fragment Polymorphism analysis of Internal Transcribed Spacer regions. Sarcinomyces crustaceus Lindner is additionally compared on the basis of 18S rDNA sequencing data. Phylogenetic analysis suggests that Phaeosclera dematioides is related to the ascomycetous order Dothideales and Monodictys castaneae to the Pleosporales, whereas the three Coniosporium species studied are a sister group to the Herpotrichiellaceae (Chaetothyriales). A similar affinity was suggested previously for the recently described meristematic rock-fungus Sarcinomyces petricola Wollenzien & de Hoog. Sarcinomyces crustaceus appears unrelated to this group, and hence the present new taxa cannot be described in this genus.

Mitochondrial DNA analysis of Exophiala jeanselmei var. lecanii-corni and Exophiala castellanii

A Japanese clinical isolate (KU-A-0094) which was identified by de Hoog et al. as Exophiala jeanselmei var. lecanii-corni with difficulty, was compared with 5 strains including the type cultures of E. jeanselmei var. lecanii-corni, var. jeanselmei and E. castellanii using RFLP (restriction fragment length polymorphism) patterns of mtDNA (mitochondrial DNA). RFLP patterns of KUA-0094 were identical with those of E. jeanselmei var. lecanii-corni and different from those of E. castellanii with restriction enzymes of HaeIII, MspI and hindIII. Therefore, de Hoog et al.'s identification of KU-A-0094 was confirmed. Additionally, mtDNA-RFLP patterns of E. jeanselmei var. lecanii-corni and E. jeanselmei var. jeanselmei were also different from each other. Consequently E. jeanselmei var. lecanii-corni seem to be a species in its own right rather than a variant of E. jeanselmei. This revised version was published online in June 2006 with corrections to the Cover Date.     

Phaeohyphomycosis caused by Exophiala moniliae

We studied two cases of phaeohyphomycosis that occurred in Japan. Histopathologic examination of biopsy material showed the presence of dematiaceous catenulate fungal cells and mycelium characteristic of phaeohyphomycosis. In detailed mycologic study of the two cultures isolated from the patients we found that both formed conidiogenous cells with proximal swellings with long, neck-like extensions bearing distinct annellations and clusters of conidia at their apices. The isolates were identified as Exophiala moniliae de Hoog. These two Japanese cases are the second and third known cases of phaeohyphomycosis caused by E. moniliae and the first recorded in that country.     

Phaeoannellomyces and the Phaeococcomycetaceae, new dematiaceous blastomycete taxa

Phaeoannellomyces McGinnis et Schell gen. nov., which is based upon P. elegans McGinnis et Schell sp. nov., is proposed for dematiaceous yeasts which produce percurrently proliferating conidiogenous cells. Cladosporium werneckii Horta is transferred to Phaeoannellomyces as P. werneckii (Horta) McGinnis et Schell comb. nov. because the most stable and distinctive synanamorph produced by this fungus consists of annellidic yeast cells. The Phaeococcomycetaceae McGinnis et Schell fam. nov. is proposed in the class Blastomycetes, division Fungi Imperfecti for the dematiaceous yeast genera Phaeoannellomyces and Phaeococcomyces de Hoog.
