Introduction
I am working at Pfister Lab, Harvard University, in the project "The Farlow Legacy: a mine of gold to solve fungal taxonomic and systematics probles in the molecular era". I am focussig my efforts on characterization of taxa that lack current treatments and sequences using preserved specimens in the Farlow Herbarium. The aim of this project is to emphasize how historical collections can be the solution to solving taxonomic and systematic problems in Fungi, specifically in the class Leotiomycetes

Question
Hi All,
Are you an expertise in getting ancient DNA? Currently I am looking researchers who have expertise in getting DNA from old herbaria collections. Even better if you have it with Ascomycota (Fungi). If so and you like to collaborate with taxonomist to work in projects about systematics, evolution and biogeography, please contact me at lquijull@gmail.com or luis_quijada@fas.harvard.edu and write in the subject of the email "ancient DNA". I am looking for collaboration to learn these technics but also you will be coauthor of the results of this project that start in July.
Best wishes
Luis
Question
Hi all, I am doing a paper based on published citations.
We would like to explore biogeographical patterns, ecology and possible introductions of pathogens in ecosystems or host shifting.
Do you know about papers that use similar methods? use citations to explore biogeography or ecology.
Can you recommend me manuscripts about it?

Question
I did not see any information about inoperculate Discomycetes. Is there somebody working Leotiomycetes in this project? This group of fungi is avoided in central-south America, but it is one of the most diverse groups in Ascomycota and their species are saprobes, pathogens, mycorrizal, endophytes and lichenized. With less than 5% of their diversity described, without sequences for the major part of the taxa together with their ecology and diversity stimations, would be a really interesting group to explore in Brazil.
Best wishes,
Luis
Question
I am reviewing the type of one fungi. It was collected in Italy and in the original description the author said it is growing on Pistacia therebinthus, Rosa and Rubus. But the type is constituted by only one branch. So I am trying to figure out what is the plant-host for this fungus.
I did some transverse section and I have some macropictures of the branch (inside the branch is hollow). Are there somebody that can help me? I do not know how to identify wood using anatomy, but maybe somebody can figure out at least at family level. It would be good enough to distinguish between Anacardiaceae and Rosaceae for the host of this fungus.
Question
Hi all,
I am trying to identify a species of the genus Rutstroemia. The sample was collected in Sicilia in a place with Pistacia terebinthus, Rosa sp. and Rubus sp. I do not know the host, it could be any of this three.
I have not been able to find reports of Rutstroemia on the genus Pistacia in Italy or Sicily, maybe there are reports in the mediterranean area that I do not know. The apothecia are brownish-red, around 1 mm, the asci 116-136 x 9.4-12 um and ascospores (7.4)11.3-13.3(15.5) x (3)4-4.5(5.7) um.
I think it could be Rutstroemia fruticeti, maybe an inmature specimen.
This species has been reported several times on Rubus and has similar morphology. If somebody from the mediterranean area, Italy or Sicily can help me I would be glad?
I add some photographs here to know your opinion.

Question
I am searching for publications about fungal biogeography. I have seen a lot of mycorrhizal fungi examples. But, are there manuscripts that show examples about worldwide distribution patterns of families or groups of fungi that are not mycorrhizal (saprobes, pathogens, endophytes)?
I would like to find manuscripts that show changes in diversity with latitude, vegetation, biomes, etc.
If you know examples, please I would be glad if you sent me an email lquijull@gmail.com or answer my question here.
Thanks in advance
Luis

In the forest ecosystems of all four Croatian biogeographic regions it is planned to perform: (1) Biodiversity research within priority groups of epigeous fungi from the phylum Basidiomycota, (2) Biodiversity research within priority groups of epigeous fungi from the phylum Ascomycota, (3) Biodiversity research of hypogeous fungi, (4) DNA barcoding of minimum 1500 fungal samples, (5) Analysis on the impact of fungal species on forest ecosystem services in Croatia.
Project
The fungal family Triblidiaceae Rehm sensu Magnes consists of three genera: Triblidium Rebent.: Fr. (4 spp. & 1 subsp.), Pseudographis Nyl. (2 spp. & 1 subsp.), and Huangshania O. E. Eriksson, (2 spp.). Triblidiaceae is currently placed within order Rhytismatales (Magnes 1997) that encompasses non-lichenized, saprobic or weakly-parasitic to pathogenic fungi. These typically produce desiccation-tolerant ascomata with heavily melanized excipula that close in arid conditions. Species of Triblidiaceae produce small, discoid or hysterioid ascomata that are robust and desiccation-tolerant, with a heavily melanized outer excipulum. Asci are unitunicate and ascospores are large, hyaline, lacking a gelatinous sheath and are phragmosporous or dictyosporous. Anamorphic states are currently unknown. Triblidiaceae are primarily saprobic on the bark of members of the plant families Fagaceae, Ericaceae, Pinaceae and Nothofagaceae. They are distributed circumglobally in temperate and boreal forests of northern latitudes, and a few collections have been made from Chilean temperate forests. Magnes’s 1997 monograph in German is comprehensive and erudite, though it has arguably not reached a North American audience as collections from this continent are limited. We propose to test the monophyly of Triblidiaceae Rehm sensu Magnes and its placement within Rhytismatales using molecular characters. Type specimens and a selection of our personal collections and herbarium materials will comprise specimens for DNA sampling. An emphasis will be placed on specimens collected and determined by Magnes that date from the early 1990’s. There are currently no published sequences from any taxon in Triblidiaceae. We will provide, in English, an updated history of the family as well as a key and taxonomy, using Magnes (1997) as a reference-point. Reference: Magnes M. 1997. Weltmonographie der Triblidiaceae.
