A new species ofRoumegueriella

A new species ofRoumegueriella (Ascomycetes; Hypocreales),R. pulchella, is described and illustrated. This fungus is characterized by its rapid growth on Czapek-yeast extract and YpSs agars at 37°C, bright yellow non-ostiolate ascomata, translucent membranaceous peridium, broadly clavate asci, and hyaline one-celled subglobose-ovoid ascospores ornamented with prominent spines. The holotype was isolated from soil in a sugarcane field in Okinawa, Japan.     

A new Cryptococcus species

Summary A newCryptococcus species,Cryptococcus gastricus, is described. Its relationship to the genusLipomyces is discussed.     

A new species of petalosporus

Summary A new species ofPetalosporus, P. anodosus, is described and illustrated. Two isolates representing this species were isolated from dung in California. The new species differs from the only other species of the genus,P. nodulosus, by the lack of thick-walled peridial hyphae with enlargements at the septa and by the absence of disarticulation of peridial elements. Peridial hyphae inP. anodosus have walls which are somewhat thickened and the cells are often variable in diameter. Conglomerate ascospores usually assume the petaloid arrangement characteristic of the genus.

一个耐热的戴氏霉新种(英文)

从海南三亚的河泥中分离获得戴氏霉属一新种,即小孢戴氏霉Taifanglania parvispora。它与相近种的主要区别是菌丝段有时稍膨大,瓶梗短和分生孢子小且呈梨形至倒卵形。基于戴氏霉属、腐质霉属、单瓶霉属和瓶霉属中一些种的ITS1-5.8S-ITS2 r DNA序列构建了系统发育树,结果表明新种与戴氏霉属亲缘关系较近,聚在一个分支中,并在该分支中独立为一亚分支。形态和分子特征分析表明小孢戴氏霉可以作为戴氏霉属中的一个新分类单元。

A new ballistosporous species of Protostelium

During surveys of the protostelids of the Hawaiian Islands and the South Island of New Zealand, an undescribed species of Protostelium was discovered fruiting on collections of substrates found in several sites on the southern and western parts of the island of Hawaii and from one site near Port Elizabeth, New Zealand. The new species, P. okumukumu, has a sporocarp with a bipartite stalk that supports a single, spherical spore. The basal portion of the stalk is straight and rigid. The upper part of the stalk is a nearly spherical apophysis. The junction between the stalk base and the apophysis is flexible such that the spore and apophysis swing back and forth as a unit. Spores are forcibly discharged from the stalk, and only the straight base of the stalk is left behind. Amoebae typical of the taxon Protostelium germinate from the spores, and when an amoeba differentiates into a prespore cell, it becomes lozenge shaped (nearly ellipsoid) in top view, as is typical for species of Protostelium. This represents the seventh species of protostelids described to have forcible spore discharge, and the possibility of forcible discharge needs to be examined in several other species.     

A new species of volvulina playfair

Summary A new species of Volvulina, V. pringsheimii, was isolated from Texas. This species differs from the well-known species of Volvulina, V. steinii, in having pyrenoids in the vegetative cells, a common gelatinous envelope surrounding the colony, a protoplasmic protrusion on the anterior end of each gamete, and spines on the secondary wall of the zygospore.This paper is dedicated to Professor Dr. E. G. Pringsheim on the occasion of his 80th birthday.
