Hypoxylon fuscoides

[Ditiola]

Several new species of Hypoxylon have been recent described: One of these H.fuscoides occurs on Alnus and is very similar to H.fuscum but has a purple rather than brown KOH extractable pigment and slightly smaller spores.

Having today tested 10 samples of Hypoxylon collected on Alnus wood from near Derby one of these was the new species (photo below)

See Field Mycology Vol.11 p.13 and the following abstract from Mycotaxon:

Mycotaxon Vol.113 (2010) p.209-235
Three new species of Hypoxylon are described from France, Portugal, and the United Kingdom based on new combinations of teleomorphic morphology. Hypoxylon fuscoides is related to H. fuscum but differs in having purple pigments. Hypoxylon lusitanicum is similar to H. perforatum but differs in having orange stromatal pigments. Hypoxylon gibriacense features glomerulate stromata and resembles the American H. shearii but has discoid ostiolar areas and different ascospores.

Very Cool, Does any one know the range of Hypoxylon fuscoides?

Hi John

There is only one record in the BMS database. When I send in my record that will make two. But until mycologists start to look for it and sent in records we will not know its distribution.
