1. A review of the genus Bulbothrix Hale: the isidiate, sorediate, and pustulate species with medullary salazinic acid

Authors: Benatti MN

Recieved: 27 November 2012, Accepted: 10 December 2012, Published: 23 January 2013

This study is a taxonomic review of ten Bulbothrix (Parmeliaceae, Lichenized Fungi) species containing salazinic acid in the medulla that reproduce by vegetative propagation or form pustules that erode into coarse granules. The current species delimitations are confirmed. New characteristics are detailed, some synonyms are rejected, others confirmed, and range extensions are added.

Keywords: bulbate cilia – norstictic acid – Parmeliaceae – Parmelinella

 

2. Detecting the variability of Hydnum ovoideisporum (Agaricomycetes, Cantharellales) on the basis of Italian collections, and H. magnorufescens sp. nov.

Hydnum ovoideisporum is a species of the Hydnum rufescens complex recently described from Spain, and characterized by having a pileus with deep orange tones, ovoid to broadly ellipsoid basidiospores, and growing in Mediterranean areas on calcareous soil. In this paper, four South Italian collections found under Quercus and traditionally determined as H. rufescens, were analyzed on the basis of morphological and molecular (ITS) data; three of them were proven to be conspecific with H. ovoideisporum even though they differ from the type by globose to subglobose spores, and one has a smooth hymenophore. H. ovoideisporum f. depauperatum f. nov. is established for accommodating specimens with a smooth hymenophoral surface. Finally, H. magnorufescens sp. nov. is established for a collection with large basidiomes without strong orange-reddish tinges, and with globose to subglobose spores.

3. Some noteworthy lichenicolous fungi from Khabarovsk Territory of Russia

Authors: Zhurbenko MP, Tugi EW

Recieved: 19 November 2012, Accepted: 08 December 2012, Published: 28 January 2013

Eight species of lichenicolous fungi are reported from the Russian Far East, seven of which are new to the area. Species concepts of Endococcus pseudocyphellariae and Subhysteropycnis maculiformans are broadened, and both species are for the first time reported from the Northern Hemisphere and on Pseudocyphellaria perpetua. Evernia esorediosa is a new host species for Lichenostigma maureri and Parmelia squarrosa for Phoma physciicola.

4. New additions of basidiomycetous fungi in Indian mycoflora

Authors: Kumari B, Atri NS

Recieved: 21 November 2012, Accepted: 10 December 2012, Published: 28 January 2013

Three new Leucoagaricus taxa were found in various localities of North West India. Leucoagaricus albidus sp. nov., Leucoagaricus barsii var. bulbobasilarus var. nov., and Leucoagaricus tener var. brevisporus var. nov. are described and illustrated.

Keywords: Agaricaeae – fleshy fungi – India – Leucoagaricus – taxonomy

 

5. Ectomycorrhizal fungi from southern Brazil – a literature-based review, their origin and potential hosts

Authors: Sulzbacher MA, Grebenc T, Jacques RJS, Antoniolli ZI

Recieved: 28 November 2012, Accepted: 20 December 2012, Published: 10 February 2013

A first list of ectomycorrhizal and putative ectomycorrhizal fungi from southern Brazil (the states of Rio Grande do Sul, Santa Catarina and Paraná), their potential hosts and origin is presented. The list is based on literature and authors observations. Ectomycorrhizal status and putative origin of listed species was assessed based on worldwide published data and, for some genera, deduced from taxonomic position of otherwise locally distributed species. A total of 144 species (including 18 doubtfull species) in 49 genera were recorded for this region, all accompanied with a brief distribution, habitat and substrate data. At least 30 collections were published only to the genus level and require further taxonomic review.

Keywords: distribution – habitat – mycorrhiza – neotropics – regional list

 

6. A checklist of agarics (gilled mushrooms) of Kerala State, India

Authors: Farook VA, Khan SS, Manimohan P

Recieved: 15 December 2012, Accepted: 04 January 2013, Published: 10 February 2013

A literature-based checklist of agarics (gilled mushrooms) occurring in Kerala State, India is provided. It consists of 616 species of gilled mushrooms belonging in 112 genera and 5 orders (Agaricales, Boletales, Gomphales, Polyporales, Russulales) of the Class Agaricomycetes, Phylum Basidiomycota. The relevant original information is contained in about 122 papers, many with only limited distribution and availability. Most of these papers have been published during the last two decades. The geographical distribution of the reports covers all 14 districts of the State. At the order level, Agaricales has the highest number of species (579), followed by Russulales (21). The six most represented genera are Hygrocybe, Entoloma (41 spp. each), Lepiota (39 spp.), Marasmius (27 spp.), Leucocoprinus and Pluteus (22 spp. each). Several of the species are known only from the region and there is a possibility that many are endemic to the region as the level of endemism in the flora and fauna of Kerala is very high. This list covers only a part of the actual diversity of gilled mushrooms in Kerala as studies on the agarics of this region have been uneven, inadequate and therefore inconclusive.

7. Auricularia olivaceus: a new species from North India

Authors: Kumari B, Upadhyay RC, Atri NS

Recieved: 18 December 2012, Accepted: 08 January 2013, Published: 27 February 2013

Auricularia olivaceus sp. nov. (family Auriculariaceae) is described and illustrated as a new species, based on collections from Himachal Pradesh, North India.

Keywords: Basidiomycetes – India – macrofungi – taxonomy

 

8. Notes on the genus Entoloma in the Northwest of the Iberian Peninsula (V). Entoloma lucense, a new species in subgenus Omphaliopsis

Authors: Blanco-Dios JB

Recieved: 20 December 2012, Accepted: 20 January 2013, Published: 28 February 2013

A full description is given of Entoloma lucense, a new species in subgenus Omphaliopsis, found in Galicia (NW of Spain). Morphological description and drawings of macro- and microscopic characters of the basidiomata are presented. Other close taxa of subgenus Omphaliopsis are discussed.

Keywords: Agaricales – Basidiomycota – Entolomataceae – Spain – taxonomy

 

9. A new species of Mycena sect. Exornatae and some taxonomic observations

Authors: Aravindakshan DM, Manimohan P

Recieved: 11 February 2013, Accepted: 24 February 2013, Published: 28 February 2013

Mycena snigdha sp. nov. is described from Kerala state, India and is assigned to sect. Exornatae. Comprehensive description, photographs, and comparisons with phenetically similar species are provided. The wide, loop-like clamp connections of M. snigdha are remarkably similar to those of species of Mycena sect. Ingratae and this observation reveals that loop-like clamp connections can no longer be used to differentiate sect. Ingratae from sect. Exornatae and supports a recent treatment of sect. Ingratae as a synonym of section Exornatae. Within sect. Exornatae, however, this feature seems to be useful in species segregation. Mycena fumosa, an Australian species currently placed in sect. Sacchariferae, is considered as belonging to sect. Exornatae.

10. A new species of non-lichenized ascomata from India

Hysterographium palamalaiense is characterized by hysterothecium ascomata with sulcus at the centre, cylindrical 8-spored asci with muriform ascospores described here as new to science.

Keywords: Hysterographium – Hysteriaceae – Palamalai hills
