Peziza and Pezizaceae Inferred from Multiple Nuclear Genes: RPB2, -Tubulin, and LSU Rdna
Molecular Phylogenetics and Evolution 36 (2005) 1–23 www.elsevier.com/locate/ympev Evolutionary relationships of the cup-fungus genus Peziza and Pezizaceae inferred from multiple nuclear genes: RPB2, -tubulin, and LSU rDNA Karen Hansen ¤, Katherine F. LoBuglio, Donald H. PWster Harvard University Herbaria, Cambridge, MA 02138, USA Received 5 May 2004; revised 17 December 2004 Available online 22 April 2005 Abstract To provide a robust phylogeny of Pezizaceae, partial sequences from two nuclear protein-coding genes, RPB2 (encoding the sec- ond largest subunit of RNA polymerase II) and -tubulin, were obtained from 69 and 72 specimens, respectively, to analyze with nuclear ribosomal large subunit RNA gene sequences (LSU). The three-gene data set includes 32 species of Peziza, and 27 species from nine additional epigeous and six hypogeous (truZe) pezizaceous genera. Analyses of the combined LSU, RPB2, and -tubulin data set using parsimony, maximum likelihood, and Bayesian approaches identify 14 Wne-scale lineages within Pezizaceae. Species of Peziza occur in eight of the lineages, spread among other genera of the family, conWrming the non-monophyly of the genus. Although parsimony analyses of the three-gene data set produced a nearly completely resolved strict consensus tree, with increased conWdence, relationships between the lineages are still resolved with mostly weak bootstrap support. Bayesian analyses of the three- gene data, however, show support for several more inclusive clades, mostly congruent with Bayesian analyses of RPB2. No strongly supported incongruence was found among phylogenies derived from the separate LSU, RPB2, and -tubulin data sets. The RPB2 region appeared to be the most informative single gene region based on resolution and clade support, and accounts for the greatest number of potentially parsimony informative characters within the combined data set, followed by the LSU and the -tubulin region. -

Reproductive Isolation: Evidence that Ascobolus stercorarius and Ascobolus furfuraceus are two species, not one Abstract Strains obtained from the germination of 30-40 year old ascospores from seven stocks of the heterothallicAscobolus stercorarius - furfuraceous complex were mated in all combinations. All st X st and fu X fu pairings were fertile (ascospores) whereas all st X fu pairings were sterile (no ascospores). Based on this reproductive isolation between st and fu strains I conclude that the complex consists of two species. The block that segregated the two species is probably some stage in the establishment of the dikaryotic phase in ascogenous hyphae. One hypothesis is that this block is at the stage of nuclear recognition.

Ascobolus Gomayapriya: a New Coprophilous Fungus from Andaman Islands, India

Niranjan M, Sarma VV 2018 – Ascobolus gomayapriya: A new coprophilous fungus from Andaman Islands, India. Studies in Fungi 3(1), 73–78, Doi 10.5943/sif/3/1/9 Abstract Ascobolus is a very large genus among coprophilous fungi colonizing dung. There are very few workers who have explored dung fungi from India. During a recent trip to Andaman Islands, examination of cow dung samples revealed a new coprophilous fungus in the genus Ascobolus and the same has been reported in this paper. The present new species A. gomayapriya colonizes and grows on cow dung. A. gomayapriya is characterized by stalked, light-greenish-yellow apothecial ascomata, long cylindrical, short pedicellate asci with rounded apical caps, positive bluing reaction to Lougal’s reagent, ascospores that are hyaline to pale yellow red, smooth, cylindrical, thick- walled with two layers, sparsely dotted verruculose surface, very thin crevices. Key words – Ascomycetes – Dung fungi – Pezizomycetidae – Pezizales – Taxonomy Introduction Coprophilous fungi are an important part of the wildlife ecosystems as they help in recycling nutrients in animal dung in a saprophytic mode (Richardson 2001). Together with protozoa, myxomycetes, bacteria, nematodes and many insects, fungi are responsible for the breakdown of animal faeces, and for recycling the nutrients they contain. These are specialized fungi, able to withstand, and in many cases are dependent on, passage through an animal’s gut before growing on the dung (Richardson 2003). -

An updated key to Thecotheus spp. is provided. Key words: Ascobolaceae, Pezizales, Thecotheus. INTRODUCTION Thecotheus Boud., in Pezizales Bessey - Ascobolaceae Boud. ex Sacc., is characterised by multiascal, angiocarpically developing, minute to medium, membranous-fleshy ascomata, with a rough or papillate disc at maturity. Asci are usually 8-spored, operculate, diffusely amyloid and congophilous, strongly protruding at maturity above the hymenial level. Spores are ellipsoidal, symmetrical to slightly or greatly inequilateral, hyaline to pale yellowish, thick-walled in the early stages, cyanophilous, smooth to verrucose, biapiculate or non-apiculate, rarely with a projecting collarette at the apiculus base, individually surrounded by a gelatinous perisporium. -

A moist chamber culture method was employed. Species from eleven genera in Sordariales, Pleosporales, Pezizales, Thelebolales and Microascales were identified. Some of the species examined are new records for Thailand. The most common species were Saccobolus citrinus, Sporormiella minima, Ascobolus immersus and Cercophora kalimpongensis. Most fungal species were found on cattle dung. Chicken dung, a rarely reported substrate for coprophilous fungi, had the least fungal species.

JANUARY, 1978 Dedicated to My Parents CONSTANTINOS & IRENE AT1IANASIADIS for they cherished the life they passed to me 3 ABSTRACT In this work with Ascobolus immersus, gene conversion at the w-78 site and of various newly isolated mutations was studied. For the w-78 site two new narrower ratio classes were detected, namely 6:2(2), 2:6(2), with numbers in parentheses giving the number of pairs of non-identical sister-spores contained in the respective octal'. The 6:2(2), 2:6(2) as well as the 4:4(2) octads detected here were used in the estimation of corresponding-site interference coincidence coefficients which showed that in agreement,with previous findings, corresponding- site interference in Ascobolus is weak. The relative frequencies of symmetrical and asymmetrical hybrid DNA at the w-78 site were investigated. It was concluded that hybrid DNA in this site occurs mainly symmetrically, in two chromatids, without excluding the possibility of asymmetrical hybrid DNA occurring, but to a smaller extent. A new method was developed for carrying out this kind of project, which will allow the study of all possible arrangements of the w-78 site and its gene conversion controlling factors.
