RECENTLY DISCOVERED FUNGI IN YORKSHIRE. 



C. CROSSLAND, F.L.S. 

 Halifax. 



The following is the second summary of newly discovered 

 Yorkshire species since the issue of the ' Yorkshire Fungus 

 Flora ' in 1905. It includes one species new to science, and 

 twenty-four new to Yorkshire. These bring the total of known 

 Yorkshire species to 2706. The numbers given under each, to 

 precede or follow, are those of the species in the Flora. 



NEW SPECIES. 



HUMARIA GLOBOSO-PULVINATA n. Sp. 



Ascophores gregarius or scattered, reddish flesh colour, 

 at first globose, then globose-pulvinate, attached by a central 

 point, disc convex, fleshy, i-ij mm. across, J - 1- mm. thick 

 flesh soft, exterior glabrous ; excipulum of interwoven, branched, 

 septate hyphse of irregular diameter, 3-51^^, cortical cells sub- 

 globose, 7-8 /X diam. ; asci broadly cylindric-clavate, rapidly 

 narrowing near the foot, often curved, 140-150 x 16-18 apex 

 truncato-rounded ; spores 8, obliquely one or irregularly two 

 seriate, hyaline, oblong-elliptical, eguttulate, continuous, smooth 

 I2x8/x; paraphyses profuse, filiform, occasionally branched, 

 3 /X diam. contents granular, reddish. 



On sediment, among Bryum avgenteum, in disused dye tank, 

 near Hebden Bridge, October 27th, 1907. — Coll. J. Needham. 



The ascophores occasionally grow in little heaps or clusters 

 of 4-8 individuals. Has the general appearance of an Ascop- 

 hanus, but the tips of the asci do not make the surface of the 

 disc uneven, nor do the asci dehisc by an operculum, as in the 

 that group, but by a slit across the apex. The spores on 

 reaching maturity occupy the upper half of the ascus, later 

 they become sub-biseriate in the upper two-fifths. 

 The apices of the asci do not stain blue with iodine. 

 Under the present arrangement of the British Discomycetes, 

 I have thought it best to include this species in the genus 

 Humaria, although M. Boudier, to whom specimens have been 

 submitted, does not consider it to be a Hiimaria as at present 

 understood, and further remarks • — ' It is intermediate between 

 Pulvinula and Pyronema, and might form a group with Ascop- 

 hamis aurora (Cronan) which I have included with Ascophanus,
