In the region of Santa Maria, Southern Brazil, we have analyzed morphologically and molecularly some interesting brown-rotting mushroom specimens closely related to Pseudomerulius curtisii. Except for minor differences in morphology and ITS sequence similarity, collections have corresponded to P. curtisii by basidiospore size and shape, the kind of hyphal system, the macromorphology, the slightly unpleasant pungent spicy smell turning stronger upon drying and, particularly, by the highly supported and closely related clade after phylogenetic analysis. Perhaps due the rarity in nature, morphological data are not abundant in literature and appears to be somewhat incomplete to discordant for the species, so we provide a more detailed description and illustrations from collected specimens.

2. Myxogastrid distribution within the leaf litter microhabitat

Authors: Rollins AW, Stephenson SL

Recieved: 26 April 2012, Accepted: 23 July 2012, Published: 10 September 2012

The moist chamber culture technique was used to examine the distribution of myxogastrids at four different levels (or strata) of the forest floor leaf litter microhabitat. Each stratum was characterized by a distinct assemblage of species; moreover, both richness and abundance varied throughout. Many species appeared to exhibit a preference for a particular stratum, whereas others were widespread. Overall, the species richness recorded in the study was relatively high considering the total area sampled. These data suggest that for any study of the forest floor litter microhabitat, an effort should be made to examine all strata so as not to miss any of the species present.

4. A new bioluminescent species of Mycena sect. Exornatae from Kerala State, India

Authors: Aravindakshan DM, Kumar TKA, Manimohan P

Recieved: 20 August 2012, Accepted: 27 August 2012, Published: 12 September 2012

Recent studies on the genus Mycena in Kerala State, India resulted in the discovery of a new species, herein described as M. deeptha. It has hallmarks of Mycena section Exornatae such as gelatinous pileipellis composed of hyphae that are covered with thorn-like excrescences, non-gelatinized stipitipellis, discoid stipe base and luminescent mycelium. A combination of characters such as larger basidiomata, fimbriate pileal margin composed of cells with elongate protrusion, cheilocystidia and caulocystidia with elongate apical projections, and the presence of detersile elements over the primordium, however, makes it unique within that section. Phylogenetic analyses based on ITS rDNA sequences using maximum parsimony and maximum likelihood methods support M. deeptha as a distinct species belonging to a clade containing M. chlorophos, a well-known luminescent species of sect. Exornatae. The ITS rDNA sequence of M. deeptha shows 99–100% similarity with those of two unidentified Mycena species (environmental samples) deposited in GenBank indicating that the new species may have a wider geographical distribution.

This paper gives an account of 293 taxa resulting from the examination of 1168 fungal exsiccates belonging to 434 host plants in 82 families. The fungal taxa are distributed among 20 genera in two families, namely, Asterinaceae: Asterina (207 species), Asterolibertia (4), Bheemamyces (2), Gangamyces (2), Ishwaramyces (1), Meliolaster (1), Prillieuxina (11), Symphaster (1), Trichasterina (1), Vishnumyces (1); Lembosiaceae: Cirsosia (5), Echidnodella (5), Echidnoides (1), Eupelte (1), Lembosia (19), Maheshwaramyces (2). The anamorphs are Asterostomella (24), Asterostomula (3), Bramhamyces (1) and Mahanteshamyces (1). A new genus, Gangamyces with its type species, G. miliusae, is proposed to accommodate Asterina-like species possessing appressoria in couplets with a stellate lumen in the hyphal cells. Asterina cassiicola, Asterina clusiacearum, Asterina homaligena, Asterina kannurensis, Asterina kodajadriensis, Asterina mallotigena, Asterina mezonevronis, Asterina murrayicola, Asterina physalidis, Bheemamyces capparidis, Gangamyces miliusae, Gangamyces shoreae, Cirsosia vateriae, Lembosia calamigena, Lembosia garciniae, Lembosia pandanacearum, Maheshwaramyces coculi, Asterostomella anogeissi, Asterostomella flacourtiae-montanae, Asterostomella shoreae, Asterostomella xylosmae, Asterostomella ziziphina and Asterostomula pavettae are new species, while, Asterina munnarensis, Asterina songii and Asterina viburnicola are new names proposed for homonyms. The new combination has effected here as Prillieuxina argyreiae based on Asterinella argyreiae. All the genera, species and infraspecific taxa are arranged alphabetically in the two families (Asterinaceae and Lembosiaceae). Individual taxa are dealt with in detail and supplemented with line drawings and or photomicrographs. Host and fungus indexes are provided.

12. Contribution to the knowledge of pestalotioid fungi of Iran

Authors: Arzanlou M, Torbati M, Khodaei S, Bakhshi M

Recieved: 18 September 2012, Accepted: 21 September 2012, Published: 16 October 2012

Pestalotioid fungi, generally comprising Bartalinia, Monochaetia, Pestalotia, Pestalotiopsis, Sarcostroma, Seimatosporium, Truncatella, are coelomycetous genera with saprobic, endophytic or plant pathogenic life styles residing in the Amphisphaeriaceae (Xylariales). Little is known about the biodiversity of pestalotioid fungi in Iran. We provide a literature-based checklist for the pestalotioid fungi known to occur on different plant species in Iran. Two species, Bartalinia pondoensis and Pestalotiopsis neglecta are characterised based on morphological and molecular data from bamboo and rock samples, respectively. This is the first record of the genus Bartalinia from Iran and first report on the occurrence of B. pondoensis on bamboo and first report of P. neglecta on rock sample worldwide.

Keywords: appendage – coelomycetes – Pestalotiopsis – Seimatosporium
